Animation State Machines

It is common for a character or other animated Game Object to have several different animations that correspond to different actions it can perform in the game. For example, a character may breathe or sway slightly while idle, walk when commanded to and raise its arms in panic as it falls from a platform. A door may have animations for opening, closing, getting jammed, and being broken open. Mecanim uses a visual layout system similar to a flow-chart, to represent a state machineThe set of states in an Animator Controller that a character or animated GameObject can be in, along with a set of transitions between those states and a variable to remember the current state. The states available will depend on the type of gameplay, but typical states include things like idling, walking, running and jumping. More info
