keep monster from despawining

[Vale]

just an idea. Im no expert in scripting, but when the map loads you could have it check a variable whether the monster is active or not. Just have the variable changed when the monster should spawn or despawn. Use a global variable.
Do you need a code example?

---

void 0nStart() //the first time the area ever loads
{
SetGlobalVarString("Monster", inactive); //sets a string variable that says the variable monster is inactive. works across all maps so each one may need "Monster" to be replaced with "Monster2", etc
}
void OnEnter() //runs whenever player enters map
{
if(GetGlobalVarString("Monster") == active) //checks when player enters that variable "Monster" is equal to active
{
SetEntityActive("monstername", true);//sets your monster active if previous statement true
}
}

when you first activate your monster, include
SetGlobalVarString("monster_variablename", active);

that code is a mess, and you may need to go over it a couple times. Everything is documented, and it should work. Hope this helps.
