I've ripped a SH2 monster (Mandarin) to GZDoom and it's supposed to climb around in the ceiling, just like an upside down A_Chase.
Perhaps with ZScript, but it's brand new to me... I've not been playing with the decorate for a while so I'm just askin right out if it is possible. I'm requesting for some suitable examples/templates if there are. Thx in adv
