Monster FriendList

[KnightmareZ]

Hello there! I have an event in a Arena where I spawn monsters with Game.createMonster(monster.name, monster.spawnPos ..). Now I would like to add friends(Players) to this monster so he wont target this person. It does add people to this list but still attacks them.

INVESTIGATION RESULT 1. Printer faced this problem where it still tried to steer to the player. Link: https://otland.net/threads/summon-auto-attacking-monster-1-0.211199/ with code examples.

INVESTIGATION RESULT 2. In monster.cpp at Monster::addTarget (Line 305~)
This process should be:
When addTarget is ran it will update monster friendList first (updateTargetList(I dont know?)).
then right before monster going to add target to his targetList, make it check if its in its friendlist. if it is, dont add it to target.

INVESTIGATION RESULT 3 - Tried to add the 4th line below but any monster never attacked any player

void Monster::addTarget(Creature* creature, bool pushFront/* = false*/)
{
    assert(creature != this);
    if (std::find(targetList.begin(), targetList.end(), creature) == targetList.end()) {
        if (std::find(friendList.begin(), friendList.end(), creature) != friendList.end()) {
            creature->incrementReferenceCounter();
            if (pushFront) {
                targetList.push_front(creature);
            } else {
                targetList.push_back(creature);
            }
        }
    }
}

INVESTIGATION RESULT 4.
In LUA:

monster:addFriend(player)

and player can be found in

monster:getFriendList().

and in monster.cpp:

if (isOpponent(creature) && isFriend(creature) == false) {[/I][/I][/I][/I][/I]
[I][I][I][I][I]        addTarget(creature, pushFront);
    }

and it still add target to player.

local monster = Game.createMonster(name, pos)
monster:addFriend(creature)

You have to use userdata or cid, not name

 

[KnightmareZ]

local monster = Game.createMonster(name, pos)
monster:addFriend(creature)

You have to use userdata or cid, not name

Thank you for your quickly response. I have updated my post for clarification. Please take a look at investigation result 2.

Edit: I am in the monsters friendlist but it keeps attacking me. Why is that?

 

[zbizu]

Try:
monster:setTarget()

There is a chance it could update targetting.

 

[KnightmareZ]

Try:
monster:setTarget()

There is a chance it could update targetting.

It doesn't updates : ( do you have any more ideas?

 

[zbizu]

try this instead of setTarget
monster:searchTarget()

 

[KnightmareZ]

try this instead of setTarget
monster:searchTarget()

still no "/

I do

 for _, c in ipairs(monster:getFriendList()) do
        print(c:getName())
    end

and it return all the playernames...

I do

monster:getFriendCount()

and it returns 1 or the actual count, but still targetList doesnt updates and attack the player.

monster:removeTarget(creature)

 

[KnightmareZ]

monster:removeTarget(creature)

Makes the creature follow you around like a summon =P and when you leave the creatures targetList and then enter it again it attacks you

@UnsineSoft solved my problem in another way - with onTargetCombat instead..

local creatures_red = "Wolf"
local creatures_blue = "Rat"

function Creature:onTargetCombat(target)
    if self:isMonster() and target:isPlayer() then
        if self:getName() == creatures_red and (target:getStorageValue(26800) == 1) then
            self:searchTarget()
            self:removeTarget(target)
            return RETURNVALUE_YOUMAYNOTATTACKTHISPLAYER
        elseif self:getName() == creatures_blue and (target:getStorageValue(26800) == 2) then
            self:searchTarget()
            self:removeTarget(target)
            return RETURNVALUE_YOUMAYNOTATTACKTHISPLAYER
        end
    end
    return true
end

also don't forget

<event class="Creature" method="onTargetCombat" enabled="1" />

cool! You did the best possible solution IMO (I would do it onThink which isn't really that efficient)
