Okay, so I've been playing about with the SourceSDK today, and I decided a simple mod would be to create a console command that would give you the mega gravity gun.
So here's what I've come up with. This is in weapon_physcannon.cpp.
It's pretty much just a modified version of trigger_weapon_dissolve.
However, it just won't compile.
Here's my errors from Visual Studio (2005):
I'm not sure if this is a source thing or something I've done completely wrong, since I'm not entirely familiar with C++.
I'm not asking for a difinitive "THIS IS HOW YOU FIX IT" guide, rather a push in the right direction, thanks.
