A How do you.....? Question. Created 17 years ago2006-09-21 09:40:05 UTC by VortigauntSlave

First, sorry about all the questions but im in the process of making a mod and most of the stuff i ask would be of great use, now the question. If you've completed Half-Life you should of seen this, chunks of rock/rubble/solid brushes that fall in the way and block your path/prevent you from backtracking (like the fight with the garg in power up), now what i would like to know is how do you do that? I've never been able to figue this out so help would be greatly appreciated.
Thanks!
Well, how do i get solid brushes to move in a map, like a box which is unpushable by the player to slide across the floor at high speed, or the unmovable rubble fall to the floor.

they're trains.

I thought it might have something to do with them, thank you.
