I am new to the world of mapping, started today in fact. The problem I am having is with the first map I made, it is basically a game of pyro volleyball. There is a 'net' in the middle with an object on top and on each side the pyro's have to try and keep the object airborne using compression blasts. So far I have everything made apart from the the prop. I want to prop to be light enough so that a compression blast will push it, I tried using Mass Scale when using prop_physics_multiplayer and changing it to 0.001 but it still won't work (moves when shot but not with the compression blast). This is my first problem, I need to find some way to make an object light enough to be hit by a compression blast and float down to the ground slower than normal without affecting the gravity for everyone else. The second one is trying to get the prop to respawn when it does hit the floor. I have read all the tutorials I could find on respawning props but they all work with buttons etc. and as the default TF2 has no use key I was looking for a way to get round it. If anyone can help me with these two problems I would be very grateful.
