Npc antlion template maker

Entity Description

Seeing as antlions were frequently used as cannon fodder in Half-Life 2, especially within Nova Prospekt, this entity is used to efficiently monitor and respawn antlions on a continuous basis. It has similar functionality to a npc_maker.

Note:The resulting antlions will only spawn on materials with the "antlionsand" surfaceprop.
