TFS 1.X+ [TFS 1.3] How to Force Monsters Only Focus Summons Always the Player Have Summons?

[Yan18]

Hello folks!

As the title said, I would like to know how to force monsters focus on the summons players always the players have summons? I tried:


in Data/Events/Scripts/creature.lua:

function Creature:onTargetCombat(target)
   
    if not self then
        return RETURNVALUE_NOERROR
    end
   
    if target:isPlayer() and self:isMonster() then
        if #target:getSummons() >= 1 then
            self:setTarget(target:getSummons()[1])
        return true
       
        else
            return false
        end
    end
       
    return RETURNVALUE_NOERROR
end

The code above even works, but constantly the monster change the target between the player and summon.

I tried too in monster.xml (monster file, not the file that contains the monsters file registered) set target chance to 0:

<targetchange interval="1000" chance="0" />

But the monsters always focus the player firstly and after that never change the target more while him lose the focus. I belive the monster focus the player first even I have summon before the monster can target, is because the source.

And lastly I tried to set in monster.xml set chance to 100 and interval to 1 in target tag bevause the first case, the monster focus firstly the player, and happen the same problem of the first case, the monster change the target constantly:

<targetchange interval="1" chance="100" />

To solve the problem, is in sourvce (C++) or in Lua?

I tested your code and noticed it refused to follow the summon.
The following worked for me.

function Creature:onTargetCombat(target)
    if target:isPlayer()
    and self:isMonster()
    and #target:getSummons() >= 1 then
        self:removeTarget(target)
        self:selectTarget(target:getSummons()[1])
    end
    if hasEventCallback(EVENT_CALLBACK_ONTARGETCOMBAT) then
        return EventCallback(EVENT_CALLBACK_ONTARGETCOMBAT, self, target)
    else
        return RETURNVALUE_NOERROR
    end
end

If you wish that monsters avoid targeting players then you will have to modify searchTarget

Thanks to try help bro! I tried your code, but I can't target none monsters. The monster focus me but after him focus the summon and keeping focusing the summon correctly. But I can't target none monster.

Your script generates an error:

Lua Script Error: [Event Interface]
data/events/scripts/creature.lua:Creature@onTargetCombat
data/events/scripts/creature.lua:29: attempt to call global 'hasEventCallback' (a nil value)
stack traceback:
        [C]: in function 'hasEventCallback'
        data/events/scripts/creature.lua:29: in function <data/events/scripts/creature.lua:9>

replace

    if hasEventCallback(EVENT_CALLBACK_ONTARGETCOMBAT) then
        return EventCallback(EVENT_CALLBACK_ONTARGETCOMBAT, self, target)
    else
        return RETURNVALUE_NOERROR
    end

with

return RETURNVALUE_NOERROR

replace

    if hasEventCallback(EVENT_CALLBACK_ONTARGETCOMBAT) then
        return EventCallback(EVENT_CALLBACK_ONTARGETCOMBAT, self, target)
    else
        return RETURNVALUE_NOERROR
    end

with

return RETURNVALUE_NOERROR

The error got was because my server doesn't have the function hasEventCallback, then your script won't works.
