Swinging Ball

The general idea for the swinging ball is:

Spawn several chain-pins from the base pin

Disable orbiting on these chain-pins

Spread the chain-pins out about 15 pixels away from each other

Pin the  chain-pins to the base (remember this is moving left and right constantly)

Once you have spawned 9 chain pins spawn the spiked ball from the last pin

Disable orbiting on the ball

Pin the ball to the final chain pin.

Finally make sure that the ball hurts the player.
