Money Limit

Spoiler:

In this example, I'll be moving the cap to 9 999 999.

I also have the code in my github branch called money, so you can pull directly from it.

Adding the Fairy Type (Em)
I was bored, so I inserted the Fairy Type in a clean copy of Pokeemerald. Do I need to say anything else?
Hopefully, this can work as a template to learn how to insert entirely new types from.

The changes can be checked in this diff:
https://github.com/pret/pokeemerald/compare/master...LOuroboros:pokeemerald:fairy_type

To quickly incorporate it into a project, you just have to track my repository via git remote and pull the branch where I did the modifications using git pull, like so:

git remote add lunos https://github.com/LOuroboros/pokeemerald
git pull lunos fairy_type

Pics:

Note: I only changed the type of Pound locally. It's not like that in the commit, though that's something everyone can see.

And that's pretty much it.​

It's been a while since I've posted anything, so here's a small feature from fire red:

[Pokeemerald] Auto-read signposts

This feature allows the player to read a signpost by walking up to it, rather than needing to press A. The player is also able to walk away while the script is running.

How to add more signposts:

• Currently, your tile must have behavior "MB_SIGNPOST" in order for this feature to work. Keep reading if you want to add new behaviors that the player can auto-read from
• You can add a new signpost type based on these defines
• Add your metatile behavior check here
• Add your custom script in the switch statement here

How to add this feature:

• git remote add ghoul https://github.com/ghoulslash/pokeemerald/
• git pull ghoul signpost

Uniquely Shuffle Arrays

This is a generic function to shuffle an array of values, for example species. It could be good for randomizers, challenge options, etc.

[Pokéfirered] Remove FRLG item use animation screen

The little animation screen that plays when you use an item on a Pokémon in the field (medicine, TM/HM, Rare Candy, evolution stone, berry) may have looked cute when it came out, but right around your 340th time seeing it you'll be reaching for the fast-forward button.

These changes remove the screen entirely, so item use looks identical to RSE: https://github.com/pret/pokefirered/commit/b5cc9eb7bc167be1ee300e74bee0a49abf452fae
(Handy if you plan on also adding "repeated medicine use".)

[EM] ADDING EVs TO TRAINERS

This tutorial will allow you to add EV values to any trainers you wish.

Spoiler:

First, in include/data.h, you need to do this in all (or some) of the trainer structs:

struct TrainerMonItemCustomMoves
{
    u16 iv;
    u8 lvl;
    [B][COLOR="Red"]u8 evs[NUM_STATS];[/COLOR][/B]
    u16 species;
    u16 heldItem;
    u16 moves[MAX_MON_MOVES];
};

Then, in src/battle_main.c, the next changes for the struct regarding the trainer type need to be done.

            case F_TRAINER_PARTY_CUSTOM_MOVESET | F_TRAINER_PARTY_HELD_ITEM:
            {
                const struct TrainerMonItemCustomMoves *partyData = gTrainers[trainerNum].party.ItemCustomMoves;

                for (j = 0; gSpeciesNames[partyData[i].species][j] != EOS; j++)
                    nameHash += gSpeciesNames[partyData[i].species][j];

                personalityValue += nameHash << 8;
                fixedIV = partyData[i].iv * 31 / 255;
                CreateMon(&party[i], partyData[i].species, partyData[i].lvl, fixedIV, TRUE, personalityValue, OT_ID_RANDOM_NO_SHINY, 0);

                SetMonData(&party[i], MON_DATA_HELD_ITEM, &partyData[i].heldItem);
                for (j = 0; j < MAX_MON_MOVES; j++)
                {
                    SetMonData(&party[i], MON_DATA_MOVE1 + j, &partyData[i].moves[j]);
                    SetMonData(&party[i], MON_DATA_PP1 + j, &gBattleMoves[partyData[i].moves[j]].pp);
                }
[B]                [COLOR="Red"]for (j = 0; j < NUM_STATS; j++)
                {
                    SetMonData(&party[i], MON_DATA_HP_EV + j, &partyData[i].evs[j]);
                }
                CalculateMonStats(&party[i]);[/COLOR][/B]
                break;
            }

Last, but not least, you need to modify the trainer party mons, so they include the new value. This is the boring part, and depending on how many trainer structs you have modified, you'll have to modify some or all the trainers. Here's an example:

static const struct TrainerMonItemCustomMoves sParty_MayRoute103Mudkip[] = {
    {
    .iv = 0,
    .lvl = 5,
    .species = SPECIES_TREECKO,
    .heldItem = ITEM_NONE,
    [B][COLOR="Red"][I].evs = {0, 0, 0, 255, 0, 255},[/I][/COLOR][/B]
    .moves = {MOVE_POUND, MOVE_LEER, MOVE_NONE, MOVE_NONE}
    }
};

Thanks to GriffinR for giving me pointers on how to build the function. Please let me know if this works.

Spoiler:

I'd just like to add on to this a little bit if I can. Adding abilities for trainers is very similar.

In include/data.h, you'll need to add u8 ability; to the trainer structs of your choice (I only did it in this one)

struct TrainerMonItemCustomMoves
{
    u16 iv;
    u8 lvl;
    u8 evs[NUM_STATS];
    u16 species;
    u16 heldItem;
    [B][COLOR="Red"]u8 ability;[/COLOR][/B]
    u16 moves[MAX_MON_MOVES];
};

Then in src/battle_main.c, you'll need to add this line

            case F_TRAINER_PARTY_CUSTOM_MOVESET | F_TRAINER_PARTY_HELD_ITEM:
            {
                const struct TrainerMonItemCustomMoves *partyData = gTrainers[trainerNum].party.ItemCustomMoves;

                for (j = 0; gSpeciesNames[partyData[i].species][j] != EOS; j++)
                    nameHash += gSpeciesNames[partyData[i].species][j];

                personalityValue += nameHash << 8;
                fixedIV = partyData[i].iv * 31 / 255;
                CreateMon(&party[i], partyData[i].species, partyData[i].lvl, fixedIV, TRUE, personalityValue, OT_ID_RANDOM_NO_SHINY, 0);

                SetMonData(&party[i], MON_DATA_HELD_ITEM, &partyData[i].heldItem);

                [B][COLOR="Red"]SetMonData(&party[i], MON_DATA_ABILITY_NUM, &partyData[i].ability);[/COLOR][/B]

                for (j = 0; j < MAX_MON_MOVES; j++)
                {
                    SetMonData(&party[i], MON_DATA_MOVE1 + j, &partyData[i].moves[j]);
                    SetMonData(&party[i], MON_DATA_PP1 + j, &gBattleMoves[partyData[i].moves[j]].pp);
                }
                for (j = 0; j < NUM_STATS; j++)
                {
                    SetMonData(&party[i], MON_DATA_HP_EV + j, &partyData[i].evs[j]);
                }
                CalculateMonStats(&party[i]);
                break;
            }

You have to add it to all the applicable trainer parties now....yay~
0 will be it's first ability, 1 it's second (or hidden if it doesn't have a second), and 2 hidden (if it has two other abilities).

static const struct TrainerMonItemCustomMoves sParty_WallyMauville[] = {
    {
    .iv = 0,
    .lvl = 5,
    .evs = {0, 0, 0, 0, 0, 0},
    .species = SPECIES_RALTS,
    .heldItem = ITEM_NONE,
    [B][COLOR="Red"].ability = 1;[/COLOR][/B] // gives Ralts the ability Trace
    .moves = {MOVE_GROWL, MOVE_CONFUSION, MOVE_NONE, MOVE_NONE}
    } 
};

I hope this helps for people who want to add extra challenge in their games.

Custom Battle Music Via Scripting (Emerald / Firered)

This modification allows you to set any song to play during the next battle from a script.

Spoiler:

1. Open include/constants/flags.h and rename one of the unused flags to FLAG_SYS_SET_BATTLE_BGM
2. Open src/pokemon.c and find the function GetBattleBGM, add the following code to the start of the function before the other if statements:

u16 GetBattleBGM(void)
{
    [COLOR="Lime"]if (FlagGet(FLAG_SYS_SET_BATTLE_BGM)){
        FlagClear(FLAG_SYS_SET_BATTLE_BGM);
        return VarGet(VAR_TEMP_F);
    }[/COLOR]
...

You can now set the battle music of the next battle like this:

setflag FLAG_SYS_SET_BATTLE_BGM
setvar VAR_TEMP_F, <song>

For example:

setflag FLAG_SYS_SET_BATTLE_BGM
setvar VAR_TEMP_F, MUS_VS_MEW
setwildbattle SPECIES_MAGIKARP, 5, ITEM_NONE
dowildbattle
end

This works with both wild and trainer battles. You could even use this in a map script to have custom wild encounter music.
Feel free to replace VAR_TEMP_F with any other variable if you need to.

Implement a metatile behavior for Feebas encounters (Emerald)

A very simple little tweak.

https://github.com/surskitty/pokeemerald/commit/fea41dbc7a8620782b1c1a67f60db6aaddca46c1

You can then use Porymap to edit Route 119, make a new tile with the behavior MB_FEEBAS, and use that tile to set that as the location for Feebas.

In ORAS, Feebas are found under the bridge next to the Weather Institute during the daytime, and by the rock in the water at the southern end of Route 119 during the night.

Display Mugshots/Other Images In The Overworld (Emerald / Firered)

This modification allows you to load images onto BG0 from a script. It can only show one 16-color image at a time.

1. Installation

Spoiler:

1. Create mugshot.c in the src folder and copy the following code to it:

Spoiler:

#include "global.h"
#include "blit.h"
#include "window.h"
#include "menu.h"
#include "palette.h"
#include "event_data.h"
#include "constants/mugshots.h"

#define MUGSHOT_PALETTE_NUM 13

struct Mugshot{
    u8 x;
    u8 y;
    u8 width;
    u8 height;
    const u32* image;
    const u16* palette;
};

void DrawMugshot(void); //VAR_0x8000 = mugshot id
void DrawMugshotAtPos(void); //VAR_0x8000 = mugshot id, VAR_0x8001 = x, VAR_0x8002 = y
void ClearMugshot(void);


static const struct Mugshot sMugshots[] = {
    //ADD YOUR MUGSHOTS HERE
};


//WindowId + 1, 0 if window is not open
static EWRAM_DATA u8 sMugshotWindow = 0;

void ClearMugshot(void){
    if(sMugshotWindow != 0){
        ClearStdWindowAndFrameToTransparent(sMugshotWindow - 1, 0);
        CopyWindowToVram(sMugshotWindow - 1, 3);
        RemoveWindow(sMugshotWindow - 1);
        sMugshotWindow = 0;
    }
}

static void DrawMugshotCore(const struct Mugshot* const mugshot, int x, int y){
    struct WindowTemplate t;
    u16 windowId;
    
    if(sMugshotWindow != 0){
        ClearMugshot();
    }
    
    #if GAME_VERSION==VERSION_EMERALD
    SetWindowTemplateFields(&t, 0, x, y, mugshot->width/8, mugshot->height/8, MUGSHOT_PALETTE_NUM, 0x40);
    #else
    t = SetWindowTemplateFields(0, x, y, mugshot->width/8, mugshot->height/8, MUGSHOT_PALETTE_NUM, 0x40);
    #endif
    windowId = AddWindow(&t);
    sMugshotWindow = windowId + 1;
    
    LoadPalette(mugshot->palette, 16 * MUGSHOT_PALETTE_NUM, 32);
    CopyToWindowPixelBuffer(windowId, (const void*)mugshot->image, 0, 0);
    PutWindowRectTilemap(windowId, 0, 0, mugshot->width/8, mugshot->height/8);
    CopyWindowToVram(windowId, 3);
}

void DrawMugshot(void){
    const struct Mugshot* const mugshot = sMugshots + VarGet(VAR_0x8000);
    DrawMugshotCore(mugshot, mugshot->x, mugshot->y);
}

void DrawMugshotAtPos(void){
    DrawMugshotCore(sMugshots + VarGet(VAR_0x8000), VarGet(VAR_0x8001), VarGet(VAR_0x8002));
}

2. Create mugshots.h in include/constants/ and copy the following to it:

Spoiler:

#ifndef GUARD_CONSTANTS_MUGSHOTS_H
#define GUARD_CONSTANTS_MUGSHOTS_H

//Add your mugshot constants here

#endif

3. Open ld_script.txt and add .text and .rodata for mugshot.o:
Add this somewhere among the other src files' text sections (for example here):

src/mugshot.o(.text);

Add this somewhere among the other src files' rodata sections (for example here):

src/mugshot.o(.rodata);

4. Open sym_ewram.txt and add this to the end:

.include "src/mugshot.o"

5. Open data/event_scripts.s and add this after the includes at the top of the file:

#include "constants/mugshots.h"

2. Adding new mugshots

Spoiler:

Your mugshot images need to be 16-color indexed PNGs. Their width and height must be multiples of 8.

(OPTIONAL). Make a new folder called "mugshots" in the graphics folder for your images, you could also just place them in some other folder.

1. Add a constant for each image in include/constants/mugshots.h, each with a number one higher than the last:

#ifndef GUARD_CONSTANTS_MUGSHOT_H
#define GUARD_CONSTANTS_MUGSHOT_H

//Add your mugshot constants here
[COLOR="Lime"]#define MUGSHOT_BLAINE 0[/COLOR]
[COLOR="Lime"]#define MUGSHOT_MAZE 1[/COLOR]

#endif

2. Load the image's tiles and palette in src/mugshot.c, above the definition of sMugshots

[COLOR="Lime"]static const u32 sMugshotImg_Blaine[] = INCBIN_U32("graphics/mugshots/blaine.4bpp.lz");
static const u16 sMugshotPal_Blaine[] = INCBIN_U16("graphics/mugshots/blaine.gbapal");

static const u32 sMugshotImg_Maze[] = INCBIN_U32("graphics/mugshots/maze.4bpp.lz");
static const u16 sMugshotPal_Maze[] = INCBIN_U16("graphics/mugshots/maze.gbapal");
[/COLOR]

The path in the incbin is the path to your image except "png" is replaced with "4bpp.lz" for the tiles and "gbapal" for the palette.


3. Create mugshot templates in sMugshots in src/mugshot.c using the images and palettes from the last step and the constants from the first step

static const struct Mugshot sMugshots[] = {
    //ADD YOUR MUGSHOTS HERE
    [COLOR="Lime"][MUGSHOT_BLAINE] = {.x = 16, .y = 5, .width = 80, .height = 72, .image = sMugshotImg_Blaine, .palette = sMugshotPal_Blaine},[/COLOR]
    [COLOR="Lime"][MUGSHOT_MAZE] = {.x = 6, .y = 1, .width = 144, .height = 96, .image = sMugshotImg_Maze, .palette = sMugshotPal_Maze},[/COLOR]
};

Note that x & y are tile coordinates, so the mugshot will be drawn at (8*x, 8*y).

3. Using mugshots in a script

Spoiler:

There are 3 new functions, which you can call with the callnative command:
DrawMugshot: draws mugshot that's id is in VAR_0x8000
DrawMugshotAtPos: draws mugshot that's id is in VAR_0x8000, at coordinates stored in VAR_0x8001 and VAR_0x8002
ClearMugshot: clears drawn mugshot

If a mugshot is drawn while one is already on the screen, the previous one is automatically cleared.

Example script:

setvar VAR_0x8000, MUGSHOT_BLAINE
callnative DrawMugshot
msgbox SomeText, MSGBOX_NPC
callnative ClearMugshot
end

SomeText:
.string "hi.$"

[Pokeemerald]Spawn an invisible Player

This feature lets us use a flag to spawn the player invisible after warping, which is useful for cutscenes (using a flag instead of requiring messy map scripts)

see the wiki post here

 

[mgriffin]

void DrawMugshot();
void DrawMugshotAtPos();
void ClearMugshot();

Hiya, I guess you're a C++ programmer. Unlike C++ where empty parens mean "no parameters", in C what you've written is prototypes that can take any arguments at all (think something like how ... is used by printf). You'd want to write, e.g. void DrawMugshot(void);. (It's not going to break anything if you don't, but it's pretty bad style and can mask errors when you get it wrong in header files!)

Locktarget Overworld scripting command (Em)
About an hour ago, SBird in Pret's Discord server brought up how the lock scripting command locks the movement of all the event objects on screen instead of just locking the event object that the Player is interacting with.
I decided to take a stab at it since it sounded like a fairly easy thing to address.

The changes can be checked in this commit:
https://github.com/LOuroboros/pokeemerald/commit/05f57351a0cf8a97134d7ef5067d4e68aab5bb1c

To quickly incorporate it into a project, you just have to track my repository via git remote and pull the branch where I did the modifications using git pull, like so:

git remote add lunos https://github.com/LOuroboros/pokeemerald
git pull lunos locktarget

Note: Depending on the feature branches you use in your project, you may need to adjust some of these values.
For example, if you added other new scripting commands to your project you'll need to change the internal ID of locktarget from 0xe3 to something else.

And that's pretty much it.​

Making Pokémon with Poison Heal be unaffected by poison in the overworld (Em)
Note: Poison Heal is an ability introduced in Gen. 4 and it's naturally not present in Pokemon Emerald by default.
This is mainly an optional thing you can add to projects that make use of DizzyEgg's battle_engine.

Earlier, Meister_anon from this forums' Discord server asked some tips because they wanted to make Pokémon with the Poison Heal ability not be affected by poison in the overworld, an effect that should have been implemented in the official games since its introduction, imo.
I decided to take a stab at it since it sounded like a fairly easy thing to do.

There are no commits this time. I won't make a branch because it's so utterly simple it doesn't warrant making one.
All you need to do is to go to the DoPoisonFieldEffect function in src/field_poison.c, and add the following check to the first if statement inside the for loop:

&& GetMonAbility(&gPlayerParty[i]) != ABILITY_POISON_HEAL

Don't forget to throw in a #include "pokemon.h" and a #include "constants/abilities.h" at the end of the header files list at the top of the file.
src/field_poison.c can't recognize constant labels for species abilities nor the GetMonAbility function by default.

Video:


And that's pretty much it.

EDIT (28/08/2023): I updated the post. I forgot to mention that include/pokemon.h has to be #included too.​

 

[Meister_anon~Master_o f_None]

Excluding pokemon with Ability POISON_HEAL from overworld poison damage.

I started it, but most credit goes to Lunos, for the fix.

This works for all decomps far as I can tell, I've checked poke-emerald and poke-firered
this change goes in the field_poison.c file

 

[Buffel Saft]

Remove the need to water berries on rainy Routes (Emerald)​

Ever watered berry trees in the thunderstorm on Route 119 and thought "this makes no sense"?

This little tweak will make any berry trees on specified routes give out their maximum number of berries all the time, as if the weather watered them for you!

Go to src\berry.c and find the function named GetBerryCountByBerryTreeId().
Replace it with the following:

static u8 GetBerryCountByBerryTreeId(u8 id)
{
    struct BerryTree *tree = GetBerryTreeInfo(id);
    const struct Berry *berry = GetBerryInfo(tree->berry);
    u16 currentMap = gMapHeader.regionMapSectionId;

    if (currentMap == MAPSEC_ROUTE_119 || currentMap == MAPSEC_ROUTE_120 || currentMap == MAPSEC_ROUTE_123)
        return berry->maxYield;
    else
        return gSaveBlock1Ptr->berryTrees[id].berryYield;
}

Then you'll probably need to add #include constants/map_groups.h at the top of src\berry.c so the compiler recognizes the map names.

The maps used here are just examples, so you can change them to whatever condition you want.

Prevent Map Fade With A Flag (Emerald)

This modification allows you to stop the screen from fading after loading a map - useful for cutscenes.

Spoiler:

1. Open include/constants/flags.h and rename one of the unused flags to FLAG_SYS_PREVENT_MAP_FADE
2. Open src/field_screen_effect.c and find the function WarpFadeInScreen, add the following if statements before the FadeScreen calls.

void WarpFadeInScreen(void)
{
    u8 previousMapType = GetLastUsedWarpMapType();
    switch (GetMapPairFadeFromType(previousMapType, GetCurrentMapType()))
    {
    case 0:
        FillPalBufferBlack();
        [COLOR="Lime"]if(!FlagGet(FLAG_SYS_PREVENT_MAP_FADE))[/COLOR]
            FadeScreen(FADE_FROM_BLACK, 0);
        break;
    case 1:
        FillPalBufferWhite();
        [COLOR="Lime"]if(!FlagGet(FLAG_SYS_PREVENT_MAP_FADE))[/COLOR]
            FadeScreen(FADE_FROM_WHITE, 0);
    }
}

Now just set the flag and the screen will stay black/white after a map loads. You can use the fadescreen command to fade the palette manually.

Here are the scripts used in the example GIF (note that the ON_TRANSITION script runs before the fading would start):

LittlerootTown_BrendansHouse_2F_MapScripts::
    map_script MAP_SCRIPT_ON_TRANSITION, LittlerootTown_BrendansHouse_2F_OnTransition
    map_script MAP_SCRIPT_ON_FRAME_TABLE, LittlerootTown_BrendansHouse_2F_OnFrame
    .byte 0

LittlerootTown_BrendansHouse_2F_OnFrame:
    map_script_2 VAR_TEMP_0, 0, LittlerootTown_BrendansHouse_2F_Lights
    .2byte 0

LittlerootTown_BrendansHouse_2F_OnTransition:
    setflag FLAG_SYS_PREVENT_MAP_FADE
    end

LittlerootTown_BrendansHouse_2F_Lights:
    msgbox Text_LittlerootTown_BrendansHouse_2F_Lights, MSGBOX_NPC
    fadescreen FADE_FROM_BLACK
    clearflag FLAG_SYS_PREVENT_MAP_FADE
    setvar VAR_TEMP_0, 1
    end

Text_LittlerootTown_BrendansHouse_2F_Lights:
    .string "...\p"
    .string "I can't see anything.\l"
    .string "Let's turn on the lights.$"

Greetings everyone, I've got a pretty desirable fix I think, with credit and thanks to Buffel Saft, for helping me understand the function, I was able to figure a simple way of adding fairy type to hidden power.

It's just a simple C trick but this should work for firered and leaf green. Emerald doesn't seem to have mystery type so unfortunately this wouldn't work for it.

in pokefirered there's a line of code that essentially says, if hidden power type is greater or equal to type mystery add 1. (this is to remove mystery type from pool of possible results.

if (gBattleStruct->dynamicMoveType >= TYPE_MYSTERY)
  gBattleStruct->dynamicMoveType++;

the ++ is the plus 1.

now from messing around with effect spore I learned a trick of replacing an effect by setting it equal to another field. And that's what I did to get fairy in.
I replaced the above with this...

if (gBattleStruct->dynamicMoveType == TYPE_MYSTERY)
  gBattleStruct->dynamicMoveType = TYPE_FAIRY;

Emerald does have the Mystery Type. Every game up to HeartGold and SoulSilver have it, in fact, as it was removed in Black and White (1).
It's highly likely your modification will work on a clean copy of Pokeemerald normally, assuming Hidden Power's type can be set to Type Mystery normally.

if (gBattleStruct->dynamicMoveType == TYPE_MYSTERY)
  gBattleStruct->dynamicMoveType = TYPE_FAIRY;

I might be mistaken, but won't this basically replace Hidden Power Dark with Fairy?

My thinking is that before the numbers worked like this:

 i | i + 1
 9 | TYPE_FIRE (10)
10 | TYPE_WATER (11)
11 | TYPE_GRASS (12)
12 | TYPE_ELECTRIC (13)
13 | TYPE_PSYCHIC (14)
14 | TYPE_ICE (15)
15 | TYPE_DRAGON (16)
16 | TYPE_DARK (17)

But now that you've replaced ++ (i.e. + 1) with turning TYPE_MYSTERY (8) into TYPE_FAIRY (18) you get this:

 i | i == 8 ? 18 : i
 9 | TYPE_FAIRY (18)
10 | TYPE_FIRE (10)
11 | TYPE_WATER (11)
12 | TYPE_GRASS (12)
13 | TYPE_ELECTRIC (13)
14 | TYPE_PSYCHIC (14)
15 | TYPE_ICE (15)
16 | TYPE_DRAGON (16)

I think you both need to generate a number that's 1 bigger and remap TYPE_MYSTERY to TYPE_FAIRY to have all the types. This might actually be working on your thread? I saw you and Buffel Saft made some changes to how dynamicMoveType was calculated.
