Fields

frame_duration: Float

The duration of the current frame.

tracker: &'a TnuaRigidBodyTracker

A sensor that collects data about the rigid body from the physics backend.

proximity_sensor: &'a TnuaProximitySensor

A sensor that tracks the distance of the character’s center from the ground.

up_direction: Dir3

The direction considered as “up”.
