Gmod suggestion!!!

Is there any way is there any way to create a restricted area line turning friendlys hostile after crossing it?

uhh… no.
But I’m sure you could if you lua’d it.

Also, you can use the NPC Control 2.x tool, and just do it manually.

I’m sure if you asked for one in the Lua section, someone might be kind enough to make one for you.

Thanks dude, your real helpfull,
