Since this thread exists for mapping questions, I thought I would put my question here.
I am a noob at mapping, with that said, I want to make a rock face that can be blown up, and then, closed again. The map I am working on I want to make a quick root, but that needs a demomans det bomb to open it. from what Ive been reading on the forums, and what I am learning, I think I need to create a func_wall, and then a ff_trigger that can be blown up, but I dont know what Im doing, so I am confused. I also have no clue what LUA is, and whether I need that for what I am doing. the rock im using is used in badlands, its that brown color rock if that helps.
