[tokugawa1]

Well i want to spawn these monsters but not at the same time. they spawn at the same time with this script and also the game crashes so here it is

void OnStart()
{
AddUseItemCallback("", "key_tomb_1", "mansion_1", "UsedKeyOnDoor", true);
SetEntityPlayerInteractCallback("key_tomb_1", "Spawn_Monster", true);
AddUseItemCallback("", "key_torture_chamber_1", "mansion_4", "UsedKeyOnDoor", true);
SetEntityPlayerInteractCallback("key_torture_chamber_1", "Spawn_Monster", true);
SetEntityPlayerInteractCallback("note_generic_3", "Spawn_Monster", true);
}


void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("mansion_1", false, true);
PlayGuiSound("unlock_door", 0.8f);
RemoveItem("key_tomb_1");
SetSwingDoorLocked("mansion_4", false, true);
PlayGuiSound("unlock_door", 0.8f);
RemoveItem("key_torture_chamber_1");
}
