Script help.

I think it will be like this, step by step:

Code: (Select All)

SetLocalVarInt("BarrelCollisionCount", 0);

Just after "void OnStart/OnEnter" you declare a variable. It doesn't have to be "BarrelCollisionCount", name it as you wish.

Code: (Select All)

AddEntityCollideCallback("BARREL NAME", "SCRIPTAREA1 NAME", "FUNCTION NAME", true, 1);
AddEntityCollideCallback("BARREL NAME", "SCRIPTAREA2 NAME", "FUNCTION NAME", true, 1);
AddEntityCollideCallback("BARREL NAME", "SCRIPTAREA3 NAME", "FUNCTION NAME", true, 1);

Here we add collide callback for 3 script areas. You can do it this way, though for more than 2 objects I usually use "for" loop.

Code: (Select All)

void FUNCTION NAME(string &in asParent, string &in asChild, int alState)
{
    AddLocalVarInt("BarrelCollisionCount", 1);
    if (GetLocalVarInt("BarrelCollisionCount")==3)
    {
        SetSwingDoorLocked("DOOR NAME", false, false);
        (And here put any other effects you would like to play. Maybe unlock sound, or something like that)
    }
}

Every time the function is played, it adds 1 to the variable and checks if the variable equals 3. On the 3rd collision it should unlock the door.

You put the SetLocalVarInt to the void OnStart() part. And if the Player must do all this to unlock a door, and if it locks again if no barrels are in place then you'll need another script.
