A scene I made recently. The main feature is the elevator. It has a few features added on compared to the elevators I have seen on the forums. It has a stopper to prevent the chain from going slack and winding the wrond way, and another to stop it from becoming over tightened. A large buffer is present at the bottom of the shaft, and this can be tersted by pressing D and breaking the chain.
The scene is based on a simple warehouse. The aim is to drive the trolley to the goods, load them on using the drag tool, then take them back to be dropped onto the truck.
The controls are as follows:
Up and down arrow keys - move elevator
Left and right arrow keys - move trolley
D key - break elevator chain
Please feel free to make comments and suggestions!
