Sorry i have changed variable name, but didn't update this line.
It should be:
lua_pushboolean(L, attackedCreatureChanged);

And as I can see I missed the semicolon in this line:
Player *player = creature->getPlayer()
should be:
Player *player = creature->getPlayer();





and did u have any example of script using getSpectators?

Unfortunately not :) But I am sure that there's a lot of them here.

You can use the following function to get all creatures able to see a specific position.
getSpectators(centerPos, rangex, rangey[, multifloor = false])

Then iterate over each of these creatures and check if it is attacking the caster:
getCreatureTarget(cid)

And if any creature is targeting your caster then simply change their's target.
voilà


To do target changing you probably have to add a new lua function because I cannot find any "setPlayerTarget"-like method.
You can do this in a similar way to function doMonsterSetTarget:

Didn't test it but should work ;) (I called it doCreatureSetTarget, not so creative :D):
Lua: 
int32_t LuaInterface::luaDoCreatureSetTarget(lua_State* L)
{
    //doCreatureSetTarget(cid, target)
    uint32_t targetId = popNumber(L);
    ScriptEnviroment* env = getEnv();

    Creature* creature = env->getCreatureByUID(popNumber(L));
    if(!creature)
    {
        errorEx(getError(LUA_ERROR_CREATURE_NOT_FOUND));
        lua_pushboolean(L, false);
        return 1;
    }

    Creature* target = env->getCreatureByUID(targetId);
    if(!target && targetId != 0)
    {
        errorEx(getError(LUA_ERROR_CREATURE_NOT_FOUND));
        lua_pushboolean(L, false);
        return 1;
    }

    lua_pushboolean(L, creature->setAttackedCreature(target));

    return 1;
}

Of course, you have to register such function somewhere here:

and add it's definition to the header file somewhere here:
github.com

3777/src/luascript.h at main · Fir3element/3777

The Forgotten Server 0.4 (rev 3777) with several improvements and bugfixes - Fir3element/3777
github.com github.com

Providing 0 as a target creature should stop attacker from targeting currently attacked creature.
doCreatureSetTarget(attacker, 0)

@esigma94 ty you so much!

i tried:
luascript.cpp
Code: 
lua_register(m_luaState, "doCreatureSetTarget", LuaInterface::luaDoCreatureSetTarget);


Code: 
int32_t LuaInterface::luaDoCreatureSetTarget(lua_State* L)
{
    //doCreatureSetTarget(cid, target)
    uint32_t targetId = popNumber(L);
    ScriptEnviroment* env = getEnv();

    Creature* creature = env->getCreatureByUID(popNumber(L));
    if(!creature)
    {
        errorEx(getError(LUA_ERROR_CREATURE_NOT_FOUND));
        lua_pushboolean(L, false);
        return 1;
    }

    Creature* target = env->getCreatureByUID(targetId);
    if(!target && targetId != 0)
    {
        errorEx(getError(LUA_ERROR_CREATURE_NOT_FOUND));
        lua_pushboolean(L, false);
        return 1;
    }

    lua_pushboolean(L, creature->setAttackedCreature(target));

    return 1;
}

luascript.h
Code: 
static int32_t luaDoCreatureSetTarget(lua_State* L);

then on spell i tried:
Code: 
local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_HEALING)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false)

function onCastSpell(cid, var)
    doCreatureSetTarget(cid, 0)
    return doCombat(cid, combat, var)
end

no errors, but didn't remove player target, it shouldn't work?

I think so. Maybe just red square suggesting that you are attacking a specific target (but you are not anymore) remains.

try to add sendCancelTarget() to lua method if target is null and creature is player. Like this:
Lua: 
int32_t LuaInterface::luaDoCreatureSetTarget(lua_State* L)
{
    //doCreatureSetTarget(cid, target)
    uint32_t targetId = popNumber(L);
    ScriptEnviroment* env = getEnv();

    Creature* creature = env->getCreatureByUID(popNumber(L));
    if(!creature)
    {
        errorEx(getError(LUA_ERROR_CREATURE_NOT_FOUND));
        lua_pushboolean(L, false);
        return 1;
    }

    Creature* target = env->getCreatureByUID(targetId);
    if(!target && targetId != 0)
    {
        errorEx(getError(LUA_ERROR_CREATURE_NOT_FOUND));
        lua_pushboolean(L, false);
        return 1;
    }

    bool attackedCreatureChanged = creature->setAttackedCreature(target);
    
    // Remove red square in client if setting target to NULL
    Player *player = creature->getPlayer()
    if(player != NULL && targetId == 0 && attackedCreatureChanged) {
        player->sendCancelTarget();
    }
    
    lua_pushboolean(L, result);

    return 1;
}

Code: 
luascript.cpp:6922:24: error: ‘result’ was not declared in this scope
     lua_pushboolean(L, result);

what is this result?
lua_pushboolean(L, result);

and did u have any example of script using getSpectators?

remove target is working :) TY

every single example of getSpectators i saw using this function was 1.0+ with that
Code: 
player:
code

did u know how to get that player variable i'm trying to use here:
Code: 
local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_HEALING)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false)

function onCastSpell(cid, var)
    doCreatureSetTarget(cid, 0)
    local spectators = getSpectators(getPlayerPosition(cid), 15, 15)
    if #spectators > 0 then
        doCreatureSetTarget(player, 0)
    end
    return doCombat(cid, combat, var)
end
