The C Menu allows you to change your player model and manipulate objects in some pretty fun ways.
Uses for the Right Clicking on an Object
This is a full list of what you can do with it.
- Edit Bones
- Make Persistant
- Drive (all most all objects except most NPCs)
- Make Statue
- Keep Upright (almost all props)
- Set on Fire (some props)
I believe this is all, I'm not sure.
Uses for your Player Model
Your player model distinctifies you. The default player model is Kleiner. There are dozens of player models for you to choose from. They are all from Half-Life 2. You can edit the color of your player and the Physics Gun Beam.
