Swim

The Swim ability will allow the character to traverse through water and is activated on collision with water layer triggers. The swim ability inherits the Detect Object Ability Base ability allowing for a broad range of water detection modes. It is recommended that the water uses a trigger setup.

Setup

  1. Select the + button in the ability list under the “Abilities” foldout of the Ultimate Character Locomotion component.
  2. Add the “Swimming Pack/Swim” ability. This ability should be positioned above the Fall ability but below the Dive and Climb from Water abilities.
  3. Perform the water setup.
  4. Set the Detect Object Ability Base parameters. In the demo scene Detect Layers is set to the Water layer.
  5. Set the Start Swim Depth, Surface Swim Depth, and the Surface Height Adjustment.
  6. Add the Swim Capsule Collider Positioner preset to the character’s Capsule Collider Positioner component. This component is located on the Character/Colliders/Capsule Collider GameObject. Ensure the Capsule Collider Positioner’s Rotation Bone and Position Bone fields are set to a Transform on the character. This can be set by enabling the Rotate Collider toggle.
  7. Add the Breath attribute and Drown ability (if necessary).
  8. Specify any Water Effects.
