Animation state machine
Arrange animations into graphs to control action flow.

It's common for a character or a GameObject to have several animations for the different actions it performs in a game. For example, a character might breath and sway slightly when idle, walk when commanded, and raise their arms when they fall from a platform. A sliding door might open, close, or jam.
Mecanim uses a state machine to arrange these actions. A state machine is a graph of nodes and connecting lines that resembles a flowchart. A state machine plays the animation linked to the current action and determines the next action. You can create a state machine for each character and GameObject in your scene.
Topic | Description |
|---|---|
| State machine basics | Learn core state machine concepts and build animation flow in the Animator window. |
| Animation states | Configure states, motions, and defaults to control what each state plays. |
| Animation parameters | Control state logic with scriptable parameters. |
| State machine transitions | Simplify complex controllers with Entry and Exit transitions between state machines. |
| Animation transitions | Blend between states and define when transitions are triggered. |
| Animation blend trees | Blend similar motions smoothly using parameters and normalized time. |
| State machine behaviors | Attach behavior scripts to states to run code on enter, update, and exit. |
| Sub-state machines | Group related states into nested machines to keep large graphs manageable. |
| Animation layers | Separate animation with layered controllers, masks, and blending modes. |
| State machine solo and mute | Preview transitions faster by soloing key paths and muting irrelevant ones. |
| Target matching | Match character parts to precise world targets during specific animation windows. |
