EventFlows

2.0.0 evfls are up.

Weather

Two identical new weather patterns were added (Fine08, Fine09). These are used on certain Kapp’n tour islands.

Weather

(using the same translations used by MeteoNook: 快晴 = Clear, 晴れ = Sunny, 曇り = Cloudy, 雨雲 = Rain Clouds, 雨 = Rain, 大雨 = Heavy Rain).

Wind

(using 海弱 = Sea, Weak; 海中 = Sea, Moderate; 海強 = Sea, Strong; 陸弱 = Land, Weak; 陸中 = Land, Moderate; 陸強 = Land, Strong; 凪 = Calm).

Ordinances

K.K. Slider must have performed to set ordinances.

Beautiful Island Ordinance

The rate at which weeds spread is roughly halved.

The rate at which random weeds appear, and the rate at which weeds grow between stages, is unchanged.

The maximum number of weeds before weed processing stops is halved from 150 to 75.

There is a 69% chance a flower rolls for reproduction despite not having been watered (watering counter will be incremented after reproduction roll as normal).

There is a 69% chance a watered flower will increment its watering counter both before and after rolling for reproduction.

Every time a flower rolls for reproduction (breeding or cloning), there is a 69% chance of calculating the odds of reproduction with counter + 1 instead (this roll is independent from the above rolls, and the +1 does not get saved).

Cockroaches are cleared and unable to spawn while the ordinance is in effect; the day the ordinance is turned off, it is as if everyone has logged in that day.

Spawns in water will only be fish (no trash or stone) or water eggs (if during Bunny Day events).

Early Bird Ordinance

Things generally open an hour earlier (closing time unchanged).

Night Owl Ordinance

Things generally close an hour later (opening time unchanged).

Bell Boom Ordinance

Item prices are generally increased by 20%. This applies more broadly than the Nook Friday discounts, and stacks with the Nook Friday discount (for a final price of 84%) when applicable.

Nook Friday

This event discounts item prices in Nook’s Cranny by 30%. You must have upgraded both Resident Services and Nook’s Cranny to encounter this event, which runs in the later portion of November.

Brewster

Unlock Conditions

The conditions for Blathers to begin the interaction to find Brewster are:

• single player mode (no local co-op)
• no visitors present
• K.K. Slider has visited
• the museum has upgraded to the point where art donations are possible
• it is not during the International Museum Day event (Stamp Rally)
• you have donated at least 1 of each of the following:
  • fish
  • sea creature
  • bug
  • fossil
  • painting or sculpture
• you are the Island Representative
• you have talked to Blathers before
• you have talked to Blathers after upgrading the museum to accept art donations
• you are not in a dream

Daily Coffee

Visiting Brewster for coffee for the first time each day will set the cPlayer:PgeCoffeeTodayFlag flag, which causes the cPlayer:PgeRegularCoffee flag to be incremented. When this flag reaches certain values, Brewster will give you certain gifts:

Brewster’s greeting will change when the flag reaches: 1, 3, 5, 7, 9, 11, 13, 15. Take out is available if the flag is at least 3.
This flag is incremented during GrowUp before the daily announcement, which means you need to get coffee on 50 days, then visit Brewster on a 51st day to get the Brewstoid.

The daily flag will reset upon backwards time-travel. Since unlike the Brewster achievement, the cPlayer:PgeRegularCoffee flag is incremented before the next day's daily announcement, this means that backwards time-travel will desynchronize the two counters, and coffee obtained before backwards time-travel in one day will not be counted for getting gifts.

• For example, if you stay on one day, get coffee then time travel back to the start of the hour, and repeat this 50 times (ending with one final backwards time travel), you will get the Brewster achievement, but none of the coffees you bought will count towards getting gifts.

Kapp’n

K.K. Slider must have performed for Kapp’n to appear (specifically: cLand: TkkFirstLive must be set). Kapp’n will refuse to send you on a tour until you have used your free NMT island ticket.

Kapp’n picks an island for you to go to right before setting sail, and unlike with NMT islands, the game does not save upon departure, so it is possible to reset for a different island. The game may save anytime after closing dialogue with Kapp’n, so it is advisable to close the game after landing, before Kapp’n finishes talking.

Island Selection

Kapp’n Boat Tour Island Rate Calculator

TL;DR

Islands marked with * are not available until the date of the island has happened once since your character was created. You cannot visit these islands unless you've visited every other one of them at least the same number of times.

First tour and tours while inviting Brewster are always Gyroid Fragment.

Bad luck adjustments for the top four island types begin after 7 tours of not visiting one of those four types of islands.

Details

A few factors will ensure you are sent to a normal gyroid fragment island (Haniwa):

• First Kapp’n tour (player-based)
• Blathers has asked you to find Brewster, and you have not invited Brewster to your island yet
• Bad belongings fortune (this will also convert the gyroid fragments into clay)

If you have good belongings fortune, you skip the following roll and get a rare island. Otherwise, the game first rolls to check if you get a normal island (78%) or a rare island (22%).

If you rolled to get a normal island (78%):

• if in the last 7 Kapp’n tours you’ve been on, there is a type of normal island you have not been sent to (because you were sent to other normal islands, or were sent to 7 rare islands in a row, etc.), a normal island type is picked randomly out of the ones you haven’t been to for the longest (uniformly at random, counters cap at 20 days)
• else the game rolls according to SelectWeight (breaking the 78% up into: 30% Haniwa, 22% Vegetable, 18% OneRoom, 8% RareHaniwa)

If you rolled to get a rare island (22%):

• rare island types that you have visited more than another rare island type are removed from the pool
• a random rare island type is picked uniformly at random from the remaining pool
• if the date that the rare island type has never happened since you created your character (as measured by current game time), you cannot go to that rare island, and instead roll for a normal island as follows:
  • if you have good belongings fortune, you get OneRoom
  • else, you get a random normal island according to SelectWeight (38.46% Haniwa, 28.21% Vegetable, 23.08% OneRoom, 10.26% RareHaniwa)
• otherwise, you get the rare island rolled

For example, if you created your character on 2021/07/16 in the Northern Hemisphere, since the date for the SeaShell island type is August 31st in Northern Hemisphere, you cannot get sent to SeaShell islands unless your game time is after 2021/08/31.

Another example: if you have visited all the rare island types 3 times, except for the StarFragment island, which you have only visited 2 times, and have good belongings luck, you are guaranteed to roll for the StarFragment island, and, depending on your player creation date, may be sent to OneRoom instead.

Note that this is based on player create time (a new profile on a 5* island will not be able to go to rare islands for some time), and game time at the time that you talk to Kapp’n (you can time travel forward to unlock but going backwards will lock them again).

An island should then be picked randomly based on the island type.

Island Types

This section is a work in progress

* this island has a date of August 1st (NH)/February 1st (SH) in KappeiTourInfoParam.bcsv, but dates are not checked during island selection for normal islands, and OneRoom is specifically singled out as a special case in code where game time should be used instead of the date in the BCSV – for some purposes. Notably, bug and fish spawn follow game time, while weather follows the island date.

All Islands

All islands have a single gyroid fragment buried on them (which becomes clay if you have a bad belongings fortune).

Most islands will have fruit trees; these will always be of your native fruit.

Flowers on these islands are randomly picked out of the flowers that are in season (on the date of the island, or game time if not set), which are not your native or sister flowers.

Unlike NMT islands, trees do not have anything in them (no coins, wasps, or furniture).

Fish and bug spawns use your game time (of when you first entered the island) and either your game date (normal islands) or the date of the island (rare islands). For example, if your game is set to March 22, 3:00 PM in the Northern Hemisphere, and

• you land on a normal glowing moss island (OneRoom) => all spawns will be those of 3:00 PM, March, until you leave the island.
• you land on a rare spring bamboo island (SpringBamboo) => all spawns will be those of 3:00 PM, May, until you leave the island.

The number of vegetables present on each plant is fixed for each island.

Bug/Fish: same as your island

Glowing Moss Island (OneRoom)

This island is fixed on the Fine00 weather pattern and will be clear or sunny depending on game time.

One rock will be a money rock.

There will be up to 5 tree branches on the ground, and a full-grown gyroid buried on the island in addition to the usual gyroid fragment. This gyroid cannot be a Brewstoid, and is picked the same way as described in the gyroids section.

Bug/Fish: same as your island

Snowing Island (SnowCrystal)

Star Fragment Island (StarPiece)

This island is fixed on the Fine08 pattern on June 15th (NH)/December 15th (SH), and will be always be nighttime* when you arrive, with shooting stars in the sky.

*bug and fish spawns still follow your island time with date set to June 15th/December 15th.

Shooting stars are calculated using your island’s weather seed for the game day (starting at 5:00 AM and ending at 4:59 AM) of June 15th (NH)/December 15th (SH) of the current year of game time, with time starting at 0:00:00 (midnight) the moment you get off Kapp’n’s boat and arrive on the island.

This means that the timings for stars for everyone on your island will be the same for the whole year. Like your own island, stars only happen between the hours of 7:00 PM and 4:00 AM; as you arrive at midnight, this means that shooting stars will stop, and dawn will break, 4 hours after you arrive.

If you remain on the island past the island time of 4:59 AM, the day simply starts over again (going from June 16th 4:59 AM -> June 15th 5:00 AM).

The weather pattern (Fine08) indicates heavier showers than the usual heavy showers you receive on your own island (Fine00); specifically, there is an 80% chance instead of 50% chance of there being stars for any given minute. Like normal heavy showers, if there are stars in any given minute, there is a 50% chance of having 8 stars within the minute, and 50% chance of having 5 stars.

Click here check exactly when shooting stars will fall.

All rocks will drop star fragments according to the following distribution:

Rocks: star fragment (2x)

Trees: coconut (8x), native fruit (4x), hardwood (3x)

Bush: hydrangea (8x)

Ground Items: tree branches (3x), star fragments (3x), large star fragment (1x)

Buried Items: gyroid fragment (1x)

Bush: hibiscus (25x)

Ground Items: tree branches (5x), stone (3x), summer shells (7x)

Rocks: normal (2x), money (1x)

Trees: coconut (6x), native fruit (5x), hardwood (5x), cedar (10x)

Bush: holly (7x)

Ground Items: tree branches (3x), stone (3x), plain mushroom (2x), round mushroom (2x), thin mushroom (2x), random mushrooms (5x), acorns (0-5x), pinecones (2-5x)

Buried Items: gyroid fragment (1x)

DIY: SeasonMushroom (mushroom DIYs)

Bug/Fish: Normal, November/May (Game Time)

There are 6 mushrooms in fixed locations that always appear (2 of each of plain/round/thin). The random mushrooms are generated like those on your island (with distributions that vary depending on island evaluation).

Each of the 15 hardwood/cedar trees can have one of the following under it: tree branch, mushroom, acorn (if hardwood), or pinecone (if cedar), in addition to the 6 fixed mushrooms, generated in the following order:

• 3 random trees are assigned tree branches
• 5 random trees are assigned random mushrooms
• up to 5 hardwood trees are assigned acorns (less if there are less than 5 unassigned hardwood trees at this point)
• up to 5 cedar trees are assigned pinecones (less if there are less than 5 unassigned cedar trees at this point)

Veggie Basket

You must buy vegetables from Leif on three different days. The DIY for veggie basket (item ID 13608) should be received the next day.

Plumeria

Plumeria is in bloom when either Hydrangea or Hibiscus is in bloom.

Friendship

Chance for villager photos and thresholds for return gifts have not changed. The types of items villagers may return as a gift have not changed.

Wisp

Thanks to Stoney#9215 for pointing these changes out.

Wisp rewards have changed significantly. Min Value/Max Value refer to the item’s buy price (Price column in ItemParam.bcsv).

Category

The rate of each category depends on whether you have a tent or a house.

Items with ItemFrom in (ShopOneRoomDefault, ShopOneRoom, ShopOneRoomMiscGoods, ShopOneRoomMiscGoodsDefault) are now also in Wisp’s pool of furniture; all items with ItemLayout = Ceiling are removed if you do not have the Pro Decorating License.

Item pools for wallpaper, flooring, and clothing remain unchanged.

Something I don’t have

The item is always an item that you have not cataloged yet, unless you have cataloged everything in the pool of items, in which case it picks randomly from the pool of items.

Something expensive

Nooks’ Cranny Not Upgraded

Nooks’ Cranny Upgraded

Redd

Redd Art Simulator

Museum Upgrade

There is code to skip Museum Level 2 (museum with no art) if you are upgrading from Museum Level 1 (Blathers’ tent), and jump straight to Museum Level 3 (museum with art gallery unlocked). This does not appear to be a bug, as certain new flags are set to explicitly mark this behaviour.

If you already upgraded to Museum Level 2 before the 2.0.0 update, you must meet the old requirements to unlock the art gallery (60+ donations).

Boat

Redd’s art inventory algorithm has not changed for the most part (it is still 10%/30%/50%/10% chance of 1/2/3/4 fake pieces of art). As before the update, there is a 20% chance of real pieces of art being something you have not donated yet.

Redd’s furniture inventory selection has changed as follows:

• Eligible ItemSizes have increased (new ones in bold): 1.0 x 1.0, 2.0 x 1.0, 2.0 x 2.0, 1.0 x 0.5, 2.0 x 0.5, 1.5 x 1.5, 1.0 x 0.5 (wall), 0.5 x 1.0 (wall), 1.0 x 1.0 (wall), 1.0 x 1.5 (wall), 1.0 x 2.0 (wall), 2.0 x 1.0 (wall), 2.0 x 1.5 (wall)
  • Ceiling items are excluded
• Eligible ItemFrom have changed for players who have upgraded Nook’s Cranny:
  • before 2.0.0: ShopDefault, ShopMiscGoods, ShopLv1, ShopLv2, ShopLargeGoods
  • after 2.0.0: ShopOneRoomDefault, ShopOneRoomMiscGoodsDefault, ShopOneRoomMiscGoods, ShopOneRoom (only items with Price <= 9999; these are all items added in 2.0.0)

If you have skipped Museum Level 2 (museum with no art), and skipped straight to Museum Level 3 (museum with art gallery unlocked), then the first time you meet Redd, all the fake art on his ship will be converted to real art (this means that there is a 10%/30%/50%/10% chance of 1/2/3/4 pieces of real art that must have a fake art analogue). This does not apply to anyone who upgrades from Museum Level 2 to Museum Level 3 after the update – such players will get a normal roll of art. This is the only time that Redd will not have at least one piece of fake art.

Harv’s Island

Mid-Week Replenished Inventory

Items that are sold out are replaced the next day. The rate for real art begins at 20%, and increases by 5% every time you buy a fake piece of art from Redd (cLand:FoxCommuneRealRate).

This pulls from the entire real art/fake art pool.

There is a maximum of two pieces of real art a week generated, before you are guaranteed fake art (cLand:FoxCommuneRealNum).

Start of Week

Before inventory is reset, any sold-out slots are replenished (but these items cannot be bought because the inventory is immediately reset right after).

At the start of the week, the entire inventory is reset as follows:

• if the shop never stocked a real piece of art (regardless of whether you bought it or not) last week, there is a 100% chance of one slot having a real piece of art, and a 30% chance of the second slot having a real piece of art.
  • note that if there were sold-out slots right before the start of the week, and a real art was generated in that slot, this does not apply, even though you had no chance to buy it.
• otherwise, both slots roll for a 30% chance of a real piece of art.

The rate for real art for mid-week replenished inventory is reset back to 20%.

The real art generated at the start of the week pulls only from the pool of real art that has a fake art analogue – art with only real versions cannot be generated at the start of the week.

Saharah

Harv’s Island

Saharah sells 8 items, which change weekly, with a 20% markup on all items. These items are pulled from:

1. ItemKind = RoomWall, ItemFrom = LaurentWallFloor (normal Saharah wallpaper)
2. ItemKind = RoomWall, ItemFrom = CmlCommune_WallFloor (new Saharah wallpaper)
3. ItemKind = RoomFloor, ItemFrom = LaurentWallFloor (normal Saharah flooring)
4. ItemKind = RoomFloor, ItemFrom = CmlCommune_WallFloor (new Saharah flooring)
5. ItemKind = Rug, ItemFrom = RugS/RugM/RugL (normal rug, any size)
6. ItemKind = Rug, ItemFrom = RugS/RugM/RugL (normal rug, any size)
7. ItemKind = Rug, ItemFrom = CmlCommune_RugS/CmlCommune_RugM/CmlCommune_RugL (new rug, any size)
8. ItemKind = Rug, ItemFrom = CmlCommune_RugS/CmlCommune_RugM/CmlCommune_RugL (new rug, any size)

Visitor

As before the 2.0.0 update, Saharah sells 5 items from unchanged pools:

1. ItemKind = Rug, ItemFrom = RugL (normal large rug)
2. ItemKind = Rug, ItemFrom = RugM (normal medium rug)
3. ItemKind = Rug, ItemFrom = RugS (normal small rug)
4. ItemKind = RoomWall, ItemFrom = LaurentWallFloor (normal Saharah wallpaper)
5. ItemKind = RoomFloor, ItemFrom = LaurentWallFloor (normal Saharah flooring)

Saharah’s inventory selection has been changed to never overlap with the inventory displayed on Harv’s Island.

Kicks

Harv’s Island

Kicks sells 11 items, which change weekly, pulled from the exact same pool as when Kicks visits your island. There is no markup.

Visitor

As before the 2.0.0 update, Kicks sells 11 items.

If Kicks’ shop has not been built on Harv’s island, the item pools are unchanged as follows:

1. Seasonality = AllYear or current season, ItemKind = Shoes, ItemFrom = ShoesBagShop (normal Kicks shoes that are in season) (x3)
2. Seasonality = AllYear or current season, ItemKind = Socks, ItemFrom = ShoesBagShop (normal Kicks socks that are in season) (x3)
3. Seasonality = AllYear or current season, ItemKind = Bag, ItemFrom = ShoesBagShop (normal Kicks bags that are in season) (x5)
   • if it is not October, ItemFrom may also be ShoesBagShop_Halloween (6 colours of impish wings)

If Kicks’ shop has been built on Harv’s island, the item pools for Kicks as a visitor change to:

1. Seasonality = AllYear or current season, ItemKind = Shoes, ItemFrom = ShoesBagShop/ShoesBagShop_Commune (normal and new Kicks shoes that are in season) (x3)
2. Seasonality = AllYear or current season, ItemKind = Socks, ItemFrom = ShoesBagShop/ShoesBagShop_Commune (normal and new Kicks socks that are in season) (x3)
3. Seasonality = AllYear or current season, ItemKind = Bag, ItemFrom = ShoesBagShop (normal Kicks bags that are in season) (x2)
   • ShoesBagShop_Halloween (the 6 colours of impish wings) are not available
4. Seasonality = AllYear or current season, ItemKind = Bag/HandBag, ItemFrom = ShoesBagShop_Commune (new Kicks bags that are in season) (x3)

Kicks’ inventory when visiting may overlap with the inventory on Harv’s island.

Note: impish wings are no longer sold by Kicks once you build the shop on Harv’s island.

Vegetables

The new vegetables generally function identically to pumpkins internally, aside from changing colors, which only pumpkins do.

Nook Miles Redemption Unlock Criteria

Some of these are from before 2.0.0 but putting here anyways.

Fortune

Selection

If you had bad fortune, you are guaranteed good fortune the next day. If you had good fortune, you have a 70% chance of getting good fortune the next day.

Your fortune is then picked randomly out of eligible good (or bad) fortunes.

May Day not available: it is either not the right time of year, or you have already gone on the May Day Tour.

Purification

If you received a bad fortune, and have at least 10000 bells on you (after paying the initial fee of 1000 bells) you will be given the option to pay 10000 bells to be purified. This causes the fortune to not be set: there will be no effects from fortune whatsoever for the day.

Each time you get purified, you will receive a random item out of the following list (all equal probability) in the mail the next day:

• mini dharma
• horseshoe door decoration
• gold turtle figurine
• power stone

Effect

Money (Good)

• Glowing Spot will contain 5k bells instead of 1000 bells
• Shaken Trees drop 300 bells instead of 100 bells
• Rock Drops (both hitting and breaking) are altered
  • Money rocks will start with the 200 bell drop instead of the 100 bell drop; the final drop after the 8000 bell drop will be a 10000 bell drop
    • Breaking the money rock before the hit timer ends will drop 10000 bells instead of 8000 bells
  • When Bunny Day events are not active, normal rocks on your island are significantly more likely to drop gold nuggets and less likely to drop stones:
    • Hitting rock once

      Item	Probability
      stone	50% -> 40%
      iron nugget	34%
      clay	15%
      gold nugget	1% -> 11%

      • Note: (with or without good money fortune) you can only get up to one gold nugget from hitting rocks on your island, governed by the cPlayer:PopDiyGoldFromStoneToday flag, per player per day, after which, any would-be gold nugget drops on your island become iron nuggets. This cap only affects hitting rocks, and not breaking them. Gold nugget drops from mystery tour islands (Nook Miles Ticket or Kapp'n Boat Tour) will count toward the limit but will not be transformed into iron nuggets.
    • Breaking before hit timer ends

      Item	Probability
      clay	49% -> 40%
      iron nugget	49% -> 40%
      gold nugget	2% -> 20%

• Balloon 1000 bell drops are replaced with 3000 bells

Money (Bad)

• There will be no Glowing Spot

• Villagers may come up to you to give you a gift
• 30% chance of being an item from ShopOneRoom or ShopOneRoomMiscGoods (some of the furniture added in the 2.0.0 update), with a max buy price of 3000 bells or 100 times friendship points in bells, whichever is higher
• 70% chance of being an item from ShopLv1, ShopLv2, or ShopMiscGoods (smaller furniture found in Nook's Cranny from before 2.0.0 update), with a max buy price of 2000 bells or 100 times friendship points in bells, whichever is higher

Belongings (Good)

• Villagers may come up to you to give you a gift
• 50% chance of being an item from ShopOneRoom or ShopOneRoomMiscGoods (some of the furniture added in the 2.0.0 update), with a max buy price of 3000 bells or 100 times friendship points in bells, whichever is higher
• 50% chance of being an item from ShopLv1, ShopLv2, or ShopMiscGoods (smaller furniture found in Nook's Cranny from before 2.0.0 update), with a max buy price of 2000 bells or 100 times friendship points in bells, whichever is higher
• Tools do not consume any durability
• If you have a tool that has already been used beyond its limits (using a shovel/axe on a rock resulting in dropped items, on a normal day will consume durability, even past its limit, even though it will not break immediately), it will still be destroyed
• You are guaranteed to roll for a rare Kapp’n island
• You are guaranteed OneRoom islands (glowing moss) when you roll for a rare Kapp’n island but your character is too new to visit it

Revealing Friendship

Asking Katrina to divine your friendship with a specific villager will indirectly tell you what level of friendship you are at with the villager. If your friendship level with the villager is less than 5, you may pay an additional 10000 bells to have her perform a friendship blessing, giving a small boost in friendship points:

* if you have never talked to the villager selected before

Cyrus Customization

The cost to customize an item is 700 * RemakeKitNum + 300 if RemakeKitNum is less than 8, and 800 * RemakeKitNum otherwise. Both the number of kits and the cost through Cyrus can be searched up on catalogue.ac.

Any item with ReBodyPatternNum != -1 or ReFabricPatternNum != -1 can be customized (effectively everything that has variants).

Gyroids

There are no requirements before buried Gyroid Fragments start growing to Gyroids – it is possible to grow Gyroid Fragments without building a house or unlocking the vaulting pole, by burying the Gyroid Fragment and ensuring the tile it is on is wet (either by rain or by watering it) before the day ends.

Gyroids may randomly spawn only after you have successfully grown a Gyroid Fragment to a Gyroid on your island (cLand:UnlockGyroidMainField). Random gyroid(s) will spawn after experiencing rain, as long as you have already grown a Gyroid Fragment into a Gyroid on your island before (even before Kapp’n is unlocked, or before you have done anything except reach a point where the game can be saved).

Both randomly spawned Gyroids and Gyroids grown from Gyroid Fragments pull from the full pool of Gyroids excluding Brewstoid uniformly. Brewstoid will never grow from a Gyroid Fragment or spawn randomly on your island. The type of Gyroid is picked first, then a variant is picked uniformly at random.

The day after rain, two Gyroids appear buried on your island (space permitting). There is a maximum of 4 buried (not placed) Gyroids on your island before Gyroids stop spawning (if you have 3 buried Gyroids before the day ends, you only get 1).

There are no limits on how many Gyroid Fragments may grow into Gyroids. Gyroid Fragments growing into Gyroids happens after Gyroids are randomly spawned, and do not affect the 4 buried Gyroid cap.

The type of Gyroid that spawns (either randomly or from a Gyroid Fragment) is fixed during GrowUp before daily announcements.

Isabelle

When complaining to Isabelle about a villagers' clothing, the villager's UsuallyTops, UsuallyCap, and UsuallyAccessory (the items currently worn) are cleared from WearStockList.

Golden Watering Can

As of 2.0.0, using the golden watering can will allow up to all 9 flowers in range of the can, if they are black roses, to produce a gold rose, even if used by a player on their own island.

HHP

Grade and Rank

Grade and Rank Calculator

You have both a Grade (cWherearenPlayer:CoordinatorGrade) which is visible to you, and a Rank (cWherearenPlayer:CoordinatorRank) which is not.

Your Grade (0 - 6) determines your pay, among other things:

*approximate, likelihood for client approaches, which result in a 10% increase in reward. See below for how this is calculated; notably, Famous Designer will have gaps of at least 14 days between approaches.

Your rank (0 - 200) is calculated from a mix of factors:

* when over 20 minutes are taken for their request; must be actively decorating (timer stops after a minute of inactivity as tested by Stoney#9215).

Approach Rate

Clients may approach you only after you have reached Famous Designer (Grade 3). Approach rate (the likelihood for client approaches) varies depending on rank, and how long it has been since either the last client approach, or since you have reached Famous Designer, whichever is more recent (cWherearenPlayer:ApproachSelectMissedCount):

(n = cWherearenPlayer:ApproachSelectMissedCount)

Note that this means that for Grade 3 (Famous Designer), since the base rate is 0%, there will always be a period of 14 days between approaches where the approach rate is 0%, resulting in no approaches happening.

The reward for completing an approach request is 10% over your grade’s salary.

Restaurant Recipes

You can acquire a recipe once a day from the restaurant; this recipe should be drawn at random out of all the recipes a villager may be found making.

Poki-Bell Exchange

You are able to exchange poki and bells after being introduced to the ABD in HHP. The exchange rate is controlled by the cWherearenPlayer:PokiRate flag, which is limited to values in the range 0-200, representing the amount of bells equal to 100 poki. The game sets this rate according to the following distribution:

The amount of bells you exchanged for poki in a day is stored in cWherearenPlayer:DailyExchangeBell and the amount of poki you exchanged for bells in a day is stored in cWherearenPlayer:DailyExchangePoki; both values are capped at 50000. There is a in-code limit of 15000 poki exchanging to bells.

Poki Item Cost

Items bought with Poki cost 90% of the Bell price, in Poki, subject to the following rounding rules:

• if the (buy) price of an item in Bells is 1111 or less, round to the nearest multiple of 10 Poki after multiplying by 90%
• if the (buy) price of an item in Bells is 1112 or more, round to the nearest multiple of 100 Poki after multiplying by 90%

Plots/Islands

Season

Each plot has a set of 4 fixed dates, corresponding to each of the four seasons; this determines the date that will be in effect for each of the seasons. The year is always set to 2020, and the hemisphere should be fixed to Northern Hemisphere.

Recommended Season

Spring

Summer

Autumn

Winter

Weather

When you pick between rain and no rain for weather, the game applies either the Rain07 or Fine07 patterns:

(using the same translations used by MeteoNook: 快晴 = Clear, 晴れ = Sunny, 曇り = Cloudy, 雨雲 = Rain Clouds, 雨 = Rain, 大雨 = Heavy Rain).
