Rigid Body Demonstration

Using different fields and constraints, I simulated the affects of gravity and momentum on different objects.  A gravity field is attached to all objects that move in this scene.  Using hinge and nail constrains, I was able to have the hammer swing and hit a ball.  The ball affected a few different objects as it flies away. Hinge constraints hold the board in place as it spins as well as holding the mallet and the cup. Two springs are attached to the doors of the next part that would swing back up and down if they were still in the camera view. Two invisible planes help keep the diamond in place as it falls.  A uniform volume field is placed down the shoot to help push the diamond faster into the wheel.  A vortex field is applied to the wheel with an initial state set before the diamond hits.  After it spins the spring that launches the heart is triggered.  The spring has a spring and hinge attached to it.  The handle his by the heart just has a hinge and gravity applied to it. The three spinning wheels are just one wheel with a spin attribute keyed that was then duplicated to create the ending scene.
