As the title says, I need a function like this

PHP Code:


//entitiy: witch
//client: a target that witch will chase 
//return true if succeed, return false if can't change witch target

bool WitchAttackTarget( int entity, int client) 


Change target when the witch incapacitates or kills victim,
I know some plugins already did this before, but there are still some problems.

Example:
1. [L4D & L4D2] Evil Witch
Spawns a new witch and give a hurt point. I think that is not good.

2. [L4D2] Relentless Witch
He uses signature "@_ZN8Infected15OnHitByVomitJarEP20CBaseComba tCharacter" on witch, but the director will call a horde.

Edit:
Thanks BHaType, xZk, cravenge and silvers, I write code here for myself

Is not exactly what you asked...

Maybe you can force the target with CommandABot

Usually, we use that for bots (clients) (Scavenge Bots use this, I think).

I have never seen a plugin to common infected/witch.

Didn't test but here are some examples.

My old practices, they work but as far as I remember the server will crash if you change the target when the witch is not scared yet

You can also literally change the target to any entity and patch the WitchAttack::IsValidEnemy function so the witch can run after anyone and not just survivors

Note:
If this still works then I might try to make a more advanced version and this is for windows only

[HarryPotter]

I will give a try and report

I just tested,
Everything works fine in windows server,
no crash, no wired behavior.

I just have a little wish,
It could be better if we can force witch to attack another target again even after witch had lost her target or killed survivor already.

Would love to see a Linux version of this.

ago I was looking for something like that, and maybe this can be useful when the witch loses her objective, but I think it only works for survivors :/:

PHP Code:

stock void WitchChangeTarget(int witch, int target)
{
    //PrintToChatAll("attacking target %N", target);
    if(GetEntProp(witch, Prop_Send, "m_bIsBurning") == 1){
        ExtinguishEntity(witch);
        SDKHooks_TakeDamage(witch, target, target, 0.0, DMG_BURN);
    }else{
        int anim = GetEntProp(witch, Prop_Send, "m_nSequence");
        SDKHooks_TakeDamage(witch, target, target, 0.0, DMG_BURN);
        SetEntProp(witch, Prop_Send, "m_nSequence", anim);
        SetVariantFloat(0.0);
        AcceptEntityInput(witch, "IgniteLifetime");
        //ExtinguishEntity(witch);// no works
        SetEntProp(witch, Prop_Send, "m_bIsBurning", 0);
        int ent = GetEntPropEnt(witch, Prop_Data, "m_hMoveChild");
        if(IsValidEnt(ent)){
            char classname[32];
            GetEntityClassname(ent, classname, sizeof(classname));
            if(strcmp(classname, "entityflame") == 0){
                SDKHook(ent, SDKHook_SetTransmit, SetTransmit_Fire);
            }
        }
    }
}

public Action SetTransmit_Fire(int entity, int client)
{
    return Plugin_Handled;
}

Working for survivors is enough to me, I will give a try

Thanks BHaType, xZk, cravenge and silvers, I write a script for myself

You might improve the method on completely removing the fire from the Witch. You could take a look at the Bots Trigger Witch plugin by Silvers.
