under the last attribute in itemAttrTypes (ITEM_ATTRIBUTE_DOORID = 1 << 22, if you haven't edited it, and use the number after << + 1 for reflection)

under ORIGIN_RANGED in CombatOrigin
[code=cpp]ORIGIN_REFLECT,[/code]
item.h
in: [code=cpp]inline static bool isIntAttrType[/code]
take the hex value (default is 0x7FFE13) and use bitwise or ( | ) with (1 << 23) and replace the hex with the new value you get (you can do this at Lua: demo) with this code:
[code=lua]print(string.format("0x%x", 0x7FFE13 | (1 << 23)))[/code]
you should now get 0xFFFE13, replace the value in isIntAttrType with the new hex value we have
under int8_t getHitChance, put:
[code=cpp] int32_t getReflection() const {
if (hasAttribute(ITEM_ATTRIBUTE_REFLECTION)) {
return getIntAttr(ITEM_ATTRIBUTE_REFLECTION);
}
return items[id].reflection;

find this code:

defense = item->getDefense();
extraDefense = item->getExtraDefense();
} else {
attack = it.attack;
defense = it.defense;
extraDefense = it.extraDefense;
}[/code]
replace it with:
[code=cpp] int32_t attack, defense, extraDefense, reflection;
if (item) {
attack = item->getAttack();
defense = item->getDefense();
extraDefense = item->getExtraDefense();
reflection = item->getReflection();
} else {
attack = it.attack;
defense = it.defense;
extraDefense = it.extraDefense;
reflection = it.reflection;

find this piece of code (should be around line 896)

}

if (extraDefense != 0) {

the rest of the code is for scripting purposes, so this isn't 100% necessary if you aren't planning on tampering with reflection using lua
luascript.h
under: [code=cpp]static int luaItemTypeGetArmor(lua_State* L);[/code]
put: [code=cpp]static int luaItemTypeGetReflection(lua_State* L);[/code]
luascript.cpp
under: [code=cpp]registerEnum(ITEM_ATTRIBUTE_DOORID)[/code]
put: [code=cpp]registerEnum(ITEM_ATTRIBUTE_REFLECTION)[/code]
under: [code=cpp]registerEnum(ORIGIN_RANGED)[/code]
put: [code=cpp]registerEnum(ORIGIN_REFLECT)[/code]
under: [code=cpp]registerMethod("ItemType", "getArmor", LuaScriptInterface::luaItemTypeGetArmor);[/code]
put: [code=cpp]registerMethod("ItemType", "getReflection", LuaScriptInterface::luaItemTypeGetReflection);[/code]
under: [code=cpp]int LuaScriptInterface::luaItemTypeGetArmor(lua_State* L)
{
// itemType:getArmor()
const ItemType* itemType = getUserdata<const ItemType>(L, 1);
if (itemType) {
lua_pushnumber(L, itemType->armor);
} else {
lua_pushnil(L);
}
return 1;
}[/code]
put: [code=cpp]int LuaScriptInterface::luaItemTypeGetReflection(lua_State* L)
{
// itemType:getReflection()
const ItemType* itemType = getUserdata<const ItemType>(L, -1);
if (itemType) {
lua_pushnumber(L, itemType->reflection);
} else {
lua_pushnil(L);
}
return 1;
}[/code]
now you can use ITEM_ATTRIBUTE_REFLECTION, ORIGIN_REFLECT, and itemType:getReflection() in your scripts
you can set reflection inside of items.xml with: [code=xml]<attribute key="reflect" value="10"/>[/code]
you can set reflection of items with lua using: [code=lua]item:setAttribute(ITEM_ATTRIBUTE_REFLECTION, 10)[/code]
also forgot, inside of game.cpp in bool Game::combatChangeHealth(Creature* attacker, Creature* target, CombatDamage& damage)
put
[code=cpp] if (!target) {
return false;
}[/code]
at the top of the function, otherwise it will crash when stepping on magic fields that damage you
