How do I make it so that a player can't pick up any "new weapons" (wall, box, etc.)?

EDIT: Also, in the

waittill()

function, which statement corresponds to which in-game event: "fake_death", "death", and "player_downed" to downing, bleeding out, and being revived?

you would mostly need to edit the code which handles the box and wall weapons triggers and make it invisible to the player you want. not an easy job :l

I just realized that my player will have to be touching a pad, meaning that he won't be able to reach any other guns anyways. Thanks for trying to help though!
