Solved How to remove creature focus?

[whitevo]

I tried to remove player target, but apparently this is not simple to do with Lua.

the only function we get to use is: creature:setTarget(target)
but the problem with that is, the target must exist near the creature

Is there any network message to remove current focus target from player/creature?

If not what should be done in sources so that creature:setTarget() will remove focus from targets?

related codes in luascript.cpp and creature.cpp

int LuaScriptInterface::luaCreatureSetTarget(lua_State* L)
{
   // creature:setTarget(target)
   Creature* creature = getUserdata<Creature>(L, 1);
   if (creature) {
       Creature* target = getCreature(L, 2);
       pushBoolean(L, creature->setAttackedCreature(target));
   } else {
       lua_pushnil(L);
   }
   return 1;
}

bool Creature::setAttackedCreature(Creature* creature)
{
   if (creature) {
       const Position& creaturePos = creature->getPosition();
       if (creaturePos.z != getPosition().z || !canSee(creaturePos)) {
           attackedCreature = nullptr;
           return false;
       }

       attackedCreature = creature;
       onAttackedCreature(attackedCreature);
       attackedCreature->onAttacked();
   } else {
       attackedCreature = nullptr;
   }

   for (Creature* summon : summons) {
       summon->setAttackedCreature(creature);
   }
   return true;
}

EDIT:
Pfft didn't even matter when the creature is player.
cant change player target.

So what I did was this.

if target and target:getId() == cid then
                if enemy:isPlayer() then
                    local previousPos = enemy:getPosition()
                    teleport(enemy, tokenPos)
                    teleport(enemy, previousPos)
                else
                    target:setTarget()
                end
            end

The tokenPos is set into middle of nowhere and when player teleported there, then it will loose target.
Still looking for better solutions.

did you tried player->sendCancelTarget()? i think it should work.

I could prolly compile once a month. So its not something i can just try.

Try this method:

enemy:setTarget(nil)

local msgPlayer = NetworkMessage()
msgPlayer:addByte(0xA3)
msgPlayer:addU32(0x00)
msgPlayer:sendToPlayer(enemy)

Try this method:

enemy:setTarget(nil)

local msgPlayer = NetworkMessage()
msgPlayer:addByte(0xA3)
msgPlayer:addU32(0x00)
msgPlayer:sendToPlayer(enemy)

enemy:setTarget(0) if it nil doesnt work.

actually you dont even need to touch the source files, i just said that because is a way to solve this, passing to lua player->sendCancelTarget() but since its only a network message lua already can do this, just add this function to your lua player lib

function Player.sendCancelTarget(self)
    local msg = NetworkMessage()
    msg:addByte(0xA3)
    msg:addU32(0x00)
    msg:sendToPlayer(self)
    msg:delete()
end

an example of usage:

function onUse(player, item, fromPosition, target, toPosition, isHotkey)
    player:sendCancelTarget()
    return true
end

this should work, if dont let me know.

Try this method:

enemy:setTarget(nil)

local msgPlayer = NetworkMessage()
msgPlayer:addByte(0xA3)
msgPlayer:addU32(0x00)
msgPlayer:sendToPlayer(enemy)

setting nil is not necessary.
Just the network message works fine.


About network messages. Did some digging and found some useful network messages, but still don't understand what byte codes I need to use to make them work.
