Method Detail

init

public static void init()

Loads the native Bullet native library and initializes the gdx-bullet extension. Must be called before any of the bullet classes/methods can be used.

init

public static void init(boolean useRefCounting)

Loads the native Bullet native library and initializes the gdx-bullet extension. Must be called before any of the bullet classes/methods can be used.

Parameters:

useRefCounting - Whether to use reference counting, causing object to be destroyed when no longer referenced. You must use BulletBase.obtain() and BulletBase.release() when using reference counting.

init

public static void init(boolean useRefCounting,
                        boolean logging)

Loads the native Bullet native library and initializes the gdx-bullet extension. Must be called before any of the bullet classes/methods can be used.

Parameters:

useRefCounting - Whether to use reference counting, causing object to be destroyed when no longer referenced. You must use BulletBase.obtain() and BulletBase.release() when using reference counting.

logging - Whether to log an error on potential errors in the application.

getShapeParts

public static void getShapeParts(Node node,
                                 boolean applyTransform,
                                 Array<com.badlogic.gdx.physics.bullet.Bullet.ShapePart> out,
                                 int offset,
                                 Pool<com.badlogic.gdx.physics.bullet.Bullet.ShapePart> pool)

getShapeParts

public static <T extends Node> void getShapeParts(Iterable<T> nodes,
                                                  Array<com.badlogic.gdx.physics.bullet.Bullet.ShapePart> out,
                                                  int offset,
                                                  Pool<com.badlogic.gdx.physics.bullet.Bullet.ShapePart> pool)

obtainStaticNodeShape

public static btCollisionShape obtainStaticNodeShape(Node node,
                                                     boolean applyTransform)

obtainStaticNodeShape

public static btCollisionShape obtainStaticNodeShape(Array<Node> nodes)

Obtain a btCollisionShape based on the specified nodes, which can be used for a static body but not for a dynamic body. Depending on the specified nodes the result will be either a btBvhTriangleMeshShape or a btCompoundShape of multiple btBvhTriangleMeshShape's. Where possible, the same btBvhTriangleMeshShape will be reused if multiple nodes use the same (mesh) part. The node transformation (translation and rotation) will be included, but scaling will be ignored.

Parameters:

nodes - The nodes for which to obtain a node, typically this would be: `model.nodes`.

Returns:

The obtained shape, if you're using reference counting then you can release the shape when no longer needed.
