Making an enemy not despawn after dying

[Cranky Old Man]

you could create a checkpoint
{
CheckPoint ("checkpoint1", "playerstart_2", "enemykill", "", "";
}

void enemykill(string &in asName, int alCount)

{
SetEntityActive("monster2", true);
SetEntityActive("monster", false);

}

Then Create another monster called monster2 and set him as inactive.
so the callback will set that monster active when you die.and the false one will
delete the first monster if he stayed spawned

That seems like a finite list. Sure, if you make ten monsters and number them 1-10, the players won't bother dying ten times over, but it's not an ideal solution.
A hunch: Does "SetEntityActive("monster", true);" after death, make the monster respawn in its spawn position?
