Make Player Only do 50% damage

[Araxyllis]

Is this as easy as I hope it is? Looking through the decompiled files and searching for the dmg formula, maybe adding a little /2 to it will do the trick, but I dont really want it to affect enemy dmg. Does someone know where there formulas are stored, or maybe a workaround to achieve what i want? I will learn as much as I can, but I feel that someone who actually knows what they are doing could tell me how to do it in a few minutes which may take me 20+ hours just to learn how to use this

Edit: Found something in line 2323 in /src/pokemon.c
s32 CalculateBaseDamage
maybe i can add something that here to change my dmg?

Find somewhere that computes damage and use GET_BATTLER_SIDE to decide if the attacker is the player?

EDIT: The process to find this was pretty simple. I browsed the battle code looking for something related to damage, I found gBattleMoveDamage and then searched the repository for that, looking for anything that was setting it. Not sure if I found the right place, but it's a start.

If i understand this correctly the upper one is used for my dmg calculation and the lower one for enemies, so maybe adding a *0.5 to the gBattleMoveDamage will do the trick, will learn how to actually compile the code and try it tomorrow

Spoiler:

static void atk05_damagecalc(void)
{
u16 sideStatus = gSideStatuses[GET_BATTLER_SIDE(gBattlerTarget)];

gBattleMoveDamage = CalculateBaseDamage(&gBattleMons[gBattlerAttacker],
&gBattleMons[gBattlerTarget],
gCurrentMove,
sideStatus,
gDynamicBasePower,
gBattleStruct->dynamicMoveType,
gBattlerAttacker,
gBattlerTarget);
gBattleMoveDamage = gBattleMoveDamage * gCritMultiplier * gBattleScripting.dmgMultiplier;
if (gStatuses3[gBattlerAttacker] & STATUS3_CHARGED_UP && gBattleMoves[gCurrentMove].type == TYPE_ELECTRIC)
gBattleMoveDamage *= 2;
if (gProtectStructs[gBattlerAttacker].helpingHand)
gBattleMoveDamage = gBattleMoveDamage * 15 / 10;
++gBattlescriptCurrInstr;
}

void AI_CalcDmg(u8 attacker, u8 defender)
{
u16 sideStatus = gSideStatuses[GET_BATTLER_SIDE(defender)];

gBattleMoveDamage = CalculateBaseDamage(&gBattleMons[attacker],
&gBattleMons[defender],
gCurrentMove,
sideStatus,
gDynamicBasePower,
gBattleStruct->dynamicMoveType,
attacker,
defender);
gDynamicBasePower = 0;
gBattleMoveDamage = gBattleMoveDamage * gCritMultiplier * gBattleScripting.dmgMultiplier;
if (gStatuses3[attacker] & STATUS3_CHARGED_UP && gBattleMoves[gCurrentMove].type == TYPE_ELECTRIC)
gBattleMoveDamage *= 2;
if (gProtectStructs[attacker].helpingHand)
gBattleMoveDamage = gBattleMoveDamage * 15 / 10;
}

I wanna say that AI_CalcDmg is used when the AI is deciding which move to use, and atk05_damagecalc is used for all actual attacks, but that's just my intuition.

Also, you probably want /2 rather than *0.5. The latter might have to use expensive floating point operations, whereas the former is an integer division.
