Gmod 10 (updated)

Yesterday, I got Gmod 10. IT IS AWESOME!!! The tools are great, the physics are great, the trap possibilities are endless. The only problem I have is that I can't figure out how to make buttons work (a.k.a. push button, activate items). There is an expansion for Gmod 10 called Wiremod. Wiremod is a more complicated tool that lets you make circutry. If I get Wiremod, then the first thing I will do is make a tripwire door trap. I hope to play soon so that I can get on this.
