use of org.terasology.engine.physics.components.shapes.BoxShapeComponent in project Terasology by MovingBlocks.

the class BulletPhysics method getShapeFor.

 * Returns the shape belonging to the given entity. It currently knows 4 different shapes: Sphere, Capsule, Cylinder
 * or arbitrary. The shape is determined based on the shape component of the given entity. If the entity has somehow
 * got multiple shapes, only one is picked. The order of priority is: Sphere, Capsule, Cylinder, arbitrary.
 * <br><br>
 * TODO: Flyweight this (take scale as parameter)
 *
 * @param entityRef the entity to get the shape of.
 * @return the shape of the entity, ready to be used by Bullet.
