  • public abstract class MoveableEntity
extends BaseGameEntity
    A base class defining an entity that moves. The entity has a local coordinate system root(0, 0) and members for defining its mass and velocity.

      • setHeading

        public void setHeading​(float x,
                       float y)
        First checks that the given heading is not a vector of zero length. If the new heading is valid this function sets the entity's heading and side vectors accordingly
        Parameters:
        x - the new heading in X
        y - the new heading in Y

      • getMaxTurnRate

        public float getMaxTurnRate()

      • setMaxTurnRate

        public void setMaxTurnRate​(float maxTurnRate)

      • isRotatedHeadingToFacePosition

        public boolean isRotatedHeadingToFacePosition​(Vector2 target)
        Given a target position, this method rotates the entity's heading and side vectors by an amount not greater than m_dMaxTurnRate until it directly faces the target.
        Parameters:
        target - the new target vector
        Returns:
        true when the heading is facing in the desired direction
