Color party menu icons by species - pret/pokecrystal GitHub Wiki
The tutorial to add a new party menu icon explains how to add a different icon for each Pokémon species, but the icons are all still red. This tutorial will explain how to color each species' icon from a set of eight palettes. (Coloring them uniquely, with the same palettes as their battle sprites, is beyond the scope of this tutorial.)
- Define the eight icon palettes
- Assign the palettes to Pokémon
- Allow sprite animations to have dynamic palette attributes
- Make party icons' sprite animation data use dynamic palettes
- Load the correct icon palettes for species and shininess
- Make the overworld Fly animation use the right palette
- Day care Pokémons use their custom palette
- Make the Move Deleter's delete move menu display shiny palettes
- Fix a bank overflow error
First we'll define the constants we need for our eight palettes. Let's edit constants/icon_constants.asm, adding them at the end of the file:
+; party menu icon palettes
+ const_def
+ const PAL_ICON_RED ; 0
+ const PAL_ICON_BLUE ; 1
+ const PAL_ICON_GREEN ; 2
+ const PAL_ICON_BROWN ; 3
+ const PAL_ICON_PINK ; 4
+ const PAL_ICON_GRAY ; 5
+ const PAL_ICON_TEAL ; 6
+ const PAL_ICON_PURPLE ; 7Then edit gfx/stats/party_menu_ob.pal to add the respective colors; delete the entire content and replace it with this:
+ RGB 27,31,27, 31,19,10, 31,07,01, 00,00,00 ; red
+ RGB 27,31,27, 31,19,10, 10,09,31, 00,00,00 ; blue
+ RGB 27,31,27, 31,19,10, 07,23,03, 00,00,00 ; green
+ RGB 27,31,27, 31,19,10, 15,10,03, 00,00,00 ; brown
+ RGB 27,31,27, 31,19,10, 29,05,13, 00,00,00 ; pink
+ RGB 27,31,27, 31,19,10, 13,13,13, 00,00,00 ; gray
+ RGB 27,31,27, 31,19,10, 03,23,21, 00,00,00 ; teal
+ RGB 27,31,27, 31,19,10, 18,04,18, 00,00,00 ; purpleFinally, edit engine/gfx/color.asm:
InitPartyMenuOBPals:
ld hl, PartyMenuOBPals
ld de, wOBPals1
- ld bc, 2 palettes
+ ld bc, 8 palettes
ld a, BANK(wOBPals1)
call FarCopyWRAM
retThese will be the eight possible colors for all 251 Pokémon (and Eggs). You can choose any colors you want, but the first two will have to be red and blue respectively, since the Fly map uses those for the player sprite at the same time as it shows the flying Pokémon. (InitPartyMenuOBPals used to only load those first two, since they were all that was needed: Chris and the Pokémon were red, Kris was blue.)
(If you've followed the tutorial to edit the player colors, and/or the tutorial to add a third player choice, that's fine; just make sure that the possible player colors all correspond to identical Pokémon icon colors.)

+
+INCLUDE "data/pokemon/menu_icon_pals.asm"
INCLUDE "data/icon_pointers.asm"
INCLUDE "gfx/icons.asm"This defines the normal and shiny color for each Pokémon. Note that EGG (index 253, or $FD) also has an entry; if you give it a different shiny color (here BLUE instead of RED) you'll be able to tell shiny Eggs apart.
The sprite animation engine has certain data for Pokémon icons, Pokémon holding items, and Pokémon holding Mail. This data is accessed at certain points in the code, like the party menu and the Fly map, and is hard-coded to use PAL_OW_RED. To change the color based on species, we need to achieve two sub-goals: get the right color corresponding to the current Pokémon species and apply that color to the sprite animation; and don't then force the animation to be red. Let's take those in reverse order; it's easier.
Edit engine/sprite_anims/core.asm:
Note: For older versions of the pokecrystal disassembly, you'll have to modify engine/gfx/sprites.asm instead (file name and location was changed as of Sep 18, 2023).
UpdateAnimFrame:

jr .doneNow we'll be able to load a species-appropriate palette index, and then load some sprite animation data; if that data uses −1 for the attribute value, it will just apply the already-loaded palette index instead. We'll see where that −1 value gets used in the next step.
First, edit constants/sprite_anim_constants.asm:

+ const SPRITE_ANIM_OAMSET_PARTY_MON_1 ; 8c
+ const SPRITE_ANIM_OAMSET_PARTY_MON_2 ; 8dWe're going to be updating the data soon for those SPRITE_ANIM_OAMSET_PARTY_MON_WITH_MAIL_* and SPRITE_ANIM_OAMSET_PARTY_MON_WITH_ITEM_* indexes; but the SPRITE_ANIM_OAMSET_RED_WALK_* indexes are used for more things than just Pokémon, so we're creating new SPRITE_ANIM_OAMSET_PARTY_MON_* indexes for plain party icons.

retAlso we need to edit engine/menus/naming_screen.asm to load the appropiate DV values to wTempMonDVs (which is used by NamingScreen_InitAnimatedMonIcon in the previous file we edited), and this depends whether the Pokémon we receive/catch ends up in the player's party or in a box. For this, let's to go NamingScreen:
NamingScreen:
...
.Pokemon:
ld a, [wCurPartySpecies]

+ cp BOXMON
+ call z, CloseSRAM
ld hl, LoadMenuMonIcon
ld a, BANK(LoadMenuMonIcon)
ld e, MONICON_NAMINGSCREEN
rst FarCall
...And finally edit ram/wram.asm:
wHandlePlayerStep:: db
- ds 1
+wCurIconMonHasItemOrMail:: db
wPartyMenuActionText:: dbThat code will load the correct icon colors on certain screens: the party menu, nickname screen, move list, and Fly map. Notably, the trade animation and overworld Fly animation do not load the new palettes. That's because those screens use some of the sprite palettes for their own elements (the trade tube, and other overworld sprites), so not all the possible species would have their correct colors available. There are different possible ways to overcome this, such as redesigning the trade and Fly animations, or converting some icon palettes on those screens, but that's left as an exercise for the reader. ;)
So far, the overworld fly animation still uses the OBJ 0 palette (the red one). An easy way to fix it is to override the colors of this palette.
We will make the palette change happen at the same time as the Pokémon sprite is loaded, which happens in FlyFunction_GetMonIcon in engine/gfx/mon_icons.asm
FlyFunction_GetMonIcon:
push de
ld a, [wTempIconSpecies]
call ReadMonMenuIcon
ld [wCurIcon], a
pop de
ld a, e
call GetIcon_a
+ ; Edit the OBJ 0 palette so that the flying Pokémon has the right colors.
+ ld a, [wTempIconSpecies]
+ ld [wCurPartySpecies], a
+ ld a, MON_DVS
+ call GetPartyParamLocation
+ call GetMenuMonIconPalette
+ add a
+ add a
+ add a
+ ld e, a
+ farcall SetFirstOBJPalette
retWe're calling SetFirstOBJPalette but it doesn't exist yet, so let's create and put it at the end of engine/gfx/color.asm:
FemalePokegearPals:
INCLUDE "gfx/pokegear/pokegear_f.pal"
+
+; Input: E must contain the offset of the selected palette from PartyMenuOBPals.
+SetFirstOBJPalette::
+ ld hl, PartyMenuOBPals
+ ld d, 0
+ add hl, de
+ ld de, wOBPals1
+ ld bc, 1 palettes
+ ld a, BANK(wOBPals1)
+ call FarCopyWRAM
+ ld a, TRUE
+ ldh [hCGBPalUpdate], a
+ jp ApplyPalsNow we need to reset the OBJ 0 palette to its red color after the player landed. To do this, edit engine/events/overworld.asm
.ReturnFromFly:
+ ld e, PAL_OW_RED
+ farcall SetFirstOBJPalette
farcall RespawnPlayerPlease note that this method is not compatible with "Make overworld sprites darker at night".
Warning: Before proceeding, double check that you added ld e, a at the end of GetMenuMonIconPalette from Chapter 5 of this tutorial.
The Day Care is on Route 34. On this Route, we can make use of 2 OBJ palettes that are unused in vanilla: PAL_OBJ_PINK and PAL_OBJ_ROCK.
We will make each Pokémon at the day care use one of those palettes.
Edit maps/Route34.asm
- object_event 14, 18, SPRITE_DAY_CARE_MON_1, SPRITEMOVEDATA_POKEMON, 2, 2, -1, -1, 0, OBJECTTYPE_SCRIPT, 0, DayCareMon1Script, EVENT_DAY_CARE_MON_1

+ object_event 14, 18, SPRITE_DAY_CARE_MON_1, SPRITEMOVEDATA_POKEMON, 2, 2, -1, -1, PAL_NPC_PINK, OBJECTTYPE_SCRIPT, 0, DayCareMon1Script, EVENT_DAY_CARE_MON_1

Add the following code at the end of LoadMapPals in engine/gfx/color.asm
.morn_day
ld de, wBGPals1 palette PAL_BG_ROOF color 1
ld bc, 4
ld a, BANK(wBGPals1)

retThe Move Deleter's delete move menu has a small problem that may go unnoticed. It will load the correct palette for all normal Pokémon, but will not show some shiny palettes (it may even show a palette not even defined in this tutorial). Thankfully, this is an easy fix.
Edit engine/pokemon/mon_menu.asm:
ChooseMoveToDelete:
ld hl, wOptions
ld a, [hl]
push af
set NO_TEXT_SCROLL, [hl]
- call LoadFontsBattleExtra
+ farcall LoadPartyMenuGFX
call .ChooseMoveToDelete
pop bc
ld a, b
ld [wOptions], a
push af
call ClearBGPalettes
pop af
retWe're done implementing the new palettes, but probably we'll have this error when building the ROM:
ERROR: main.asm(324) -> engine/gfx/mon_icons.asm(556) -> gfx/icons.asm(40):
Section 'bank23' is too big (max size = 0x4000 bytes, reached 0x403F).
All that code and data we added has overflowed section "bank23", which layout.link tells us is in ROM bank $23. (Okay, duh, but not every section is named after its bank.) We need to move some content to a different bank.
It turns out that engine/gfx/mon_icons.asm INCLUDEs gfx/icons.asm, which is just all the icon graphics. They're loaded by bank anyway, so they can freely be placed in any bank without causing errors.
Edit gfx/icons.asm:
+SECTION "Mon Icons", ROMX
+
Icons: ; used only for BANK(Icons)
NullIcon:
PoliwagIcon: INCBIN "gfx/icons/poliwag.2bpp"
JigglypuffIcon: INCBIN "gfx/icons/jigglypuff.2bpp"
DiglettIcon: INCBIN "gfx/icons/diglett.2bpp"
...Now it builds correctly!
This is totally compatible with the tutorial to add a unique icon for each Pokémon; in that tutorial, we just split gfx/icons.asm into more than one section, and change how the graphics' bank is determined.
