Examples with BoxShape com.bulletphysics.collision.shapes.BoxShape used on opensource projects

Example 1 with BoxShape

use of com.bulletphysics.collision.shapes.BoxShape in project jmonkeyengine by jMonkeyEngine.

the class BoxCollisionShape method createShape.

protected void createShape() {
    cShape = new BoxShape(Converter.convert(halfExtents));
    cShape.setLocalScaling(Converter.convert(getScale()));
    cShape.setMargin(margin);
}

Example 2 with BoxShape

use of com.bulletphysics.collision.shapes.BoxShape 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 entity the entity to get the shape of.
 * @return the shape of the entity, ready to be used by Bullet.
