Description

Component for 2D physics-based movement.

Stores configuration and runtime state for 2D physics-based movement. This component is used by the Move2DSystem to apply smooth acceleration and deceleration to the entity.

The component receives input via move() which sets target direction and throttle. The actual physics simulation (integration of velocity, application of dampening) is performed by the Move2DSystem.

info

Rotation/heading is handled separately by SteeringComponent and SteeringSystem.
