> Documentation for 🔸Locomotion.

General movement animations are implemented in the `AC_CAS_FPSPack_Template` controller:

Structurally, it's identical to the demo [AC\_CAS\_Template](/cas/core/example-content/animations#animator-controller) animator. The only difference is the **IK\_Locomotion** layer:

<Info>
  **Tip**: This layer is responsible for IK movement animations, such as idle, walk, sprint and jump.

**IK\_Locomotion** uses a special Avatar Mask to only affect the `ik_hand_gun_additive` bone.

This additive bone is animated in movement animation clips from the FPS Animation Pack:
