Gator

For this blender project I made a gator, with armature and animation included.

What you see here is a still of the gator chomping a box.  When you press space, the chomp animation plays.  It also sets off a property above zero, and that when it runs into the box with that property above zero it will end the box.  A countdown limits the duration of this.
In order to accomplish such a task, I had to connect sensors from different objects.  The collision detection is still simple, but it's a start.
I used an armature to do the animation.  The gator has not only a walk animation, but also a chomp animation.  I wonder...I could probably make an independant swim animation too, that is activated by collision with water.
