When you select the new Animator Override Controller in the inspector, it will initially be unassigned, and will look like this: An Animator Override Controller with no Animator Controller assigned The Animator Override Controller has a very similar icon to the Animator Controller, except that it has a “plus” sign rather than a “play” sign in the corner of the icon: Comparing icons: The Animator Controller and the Animator Override Controller assets side-by-side To create a new Animator Override Controller, use the Assets -> Create menu, or the Create button in the Project view, and select Animator Override Controller. However, using an Animator Override Controller, the basic logic for how to transistion and blend between movement states can be shared between different characters with different sets of animation, reducing the work required building and modifying state machines themselves. The Ogre may have a different way of idling and moving around, perhaps with slower, heavier and more muscular motion.

To extend this general NPC state machine to use unique animations which just apply to - say - an ogre-type character, you can create an Animator Override Controller and drop in the Ogre’s animation clips as replacements to the original animation clips. This represents an Animator Controller containing a simple state machine with a blend tree controlling animations in four directions, plus an idle animation, looking like this: To demonstrate, here’s a typical Animator Controller asset: For example, your game may have a variety of NPC types living in the world, but each type (goblin, ogre, elf, etc) has their own unique animations for walking, idling, sitting, etc.īy creating one “base” Animator Controller containing the logic for all NPC types, you could then create an override for each type and drop in their respective animation files. This allows you to create multiple variants of the same basic state machine, but with each using different sets of animations. The Animator Override Controller is a type of asset which allows you to extend an existing Animator Controller, replacing the specific animations used but otherwise retaining the original’s structure, parameters and logic.
