Example 2 with BoxShapeComponent

use of org.terasology.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.

 * TODO: Flyweight this (take scale as parameter)
 *
 * @param entity the entity to get the shape of.
 * @return the shape of the entity, ready to be used by Bullet.
