That works fearsomely
That was immensely helpful. Thank you. I have only four doors that can be so opened so I can make a script for each (some having two plates, one on each side, so that generic line that you gave really helps!).

There must be some discussion about making monsters fight each other, but it's hard to get the forum search engine to narrow that down.

So I'll post the question here, at the risk of repeating a thread: How can we get monster A to attack monster B and vice versa?
