[SCRIPT] Enemy Hallucination not Working

[Tripication]

the true would mean that it is set to yes, it is a Hallucination.
The easiest way is just to have the set entity active and then click the monster in the map editor and tick the Is Hallucination box, and set the end distance to 1 or whatever. Remove the SetEnemyIsHallucination line and make sure you save your map and check the spelling in relation to the map and the script.
