I'm trying to do some things with the Box 2D extension for flash, I'm new with this extension and I want to ask a few questions about this.
1) I know how to do very basic shapes, but how I can make triangular shapes?, like a ramp.
2) How I can do simple collision? for example, object A collides with the object B then the object A is destroyed.
3) And finally, how I can make a cannon that shoots bullets with physics?
