Bridge Crane in Unity 3D simulator (very simplified version)

Before creating a large project of a Bridge Crane Simulator ([login to view URL]), we want to create a small demo to validate some aspects of the game, specially physics and objects interactions. We have created a mind map as specification: [login to view URL] Press 'f' to expand nodes! Mind map is better but for those who like a textual description here follows a simplified version: Crane Simulator 1. Introduction First person game with the player inside a shed with only the bridge crane and some loads. 2. Game Play 2.1. Controls Numpad for crane and WASD + mouse look for player 2.2 Cameras First person 3. Artwork & animations Loads with basic primitives (cube, for instance) and bridge crane can be bought. 4. Physics (most important part with Ultimate Hope Asset) G force must act on elements Trolley and motor forces should be applied to the hope and load creating pendulum movements. Ultimate Hope asset will probably do it all. 5 . Mechanics Interactions between Load <> Hope, Trolley <> Bridge, and Crane <> Runways must be modeled. Fell free to ask any question
