How do i make a monster appear with a trigger (solution)

[TEJR]

Here ya go. "ScriptArea_1" is the name of the script area where you collide which causes the monster to spawn. "MonsterFunc1" is the name of the function used later on when you want to add to the script instead of it doing nothing. "servant_grunt" is the name of the monster that spawns. If you don't know how to actually place a scriptarea or to place and setup a monster, then ask me.

void OnStart()
{
AddEntityCollideCallback("Player" , "ScriptArea_1" , "MonsterFunc1" , true , 1);
}
void MonsterFunc1(string &in asParent , string &in asChild , int alState)
{
SetEntityActive("servant_grunt" , true);
}

Ok thanke you but where i must put this text? (i mean this script)

In the same folder as your map.
If your map is called "castle.map" the script file has to be "castle.hps".
You can edit those files with a texteditor.
