Hi all me again; ive come with more newby questions. First off how do you make it so that players cannot walk to/through a certain area? Sort of like what you do with the respawn areas where you put up a wall that stops the enemy team from going into the enemy spawn; I want to do that but for areas I dont want people of either team to go. An example would be in hydro where theres this railing on the side of this pathway that goes to like the side of a cliff. You can see the railing and when you see it you think you can jump over the railing and off the cliff, but you cant. I want to know how to do that. Is there some sort of func_entity that i can tie to a brush or something like that? Also, im curious about how exactly to make water. I really have no idea whatsoever and if theres a tutorial or whatnot on this forum or somewhere can you guys tell me where/tell me how to create water? Thanks alot!
