ReadonlyvelocityGravity magnitude applied along -Y each move.
Current capsule-center world position.
Current ground classification.
True when standing on walkable ground.
Normal of the ground under the feet (up if airborne).
Sets the capsule's facing (usually left identity; rotate the model instead).
Sets a vertical launch velocity if currently grounded (a jump).
Advances the character by dt: integrates gravity into velocity.y, sweeps
the capsule through the world (sliding, stairs, floor-stick) and writes the
collision-resolved position and velocity back. Set the desired horizontal
velocity (and any jump on velocity.y) before calling.
Frees the Jolt objects backing this controller.
Desired velocity (world units/sec). Set horizontal each frame; move integrates gravity into Y and resolves collisions, then writes the result back here.
