For my Senior Capstone Game at Champlain College, Choo Choo Boom Boom, I was tasked with creating the rigs for our games three main guns. The main cannon has two guns attached to a base for heavy and light shot variations, and the "BFRG" is a charged rail gun that is shot for more cinematic parts of the game. These mechanical rigs had a focus on set driven key animation, with custom attributes for gate openings, extending and retracting the gun barrels, and switching between an orient or aim constraint for rotating the gun barrels.
