Method Detail

createMeshShape

public static CollisionShape createMeshShape(com.jme3.scene.Spatial spatial)

Create a mesh shape for the given Spatial.

This type of collision shape is mesh-accurate and meant for immovable "world objects". Examples include terrain, houses or whole shooter levels.

Objects with "mesh" type collision shape will not collide with each other.

Creates a HeightfieldCollisionShape if the supplied spatial is a TerrainQuad.

Parameters:

spatial - the spatial on which to base the shape (not null)

Returns:

A MeshCollisionShape or a CompoundCollisionShape with MeshCollisionShapes as children if the supplied spatial is a Node. A HeightieldCollisionShape if a TerrainQuad was supplied.

createDynamicMeshShape

public static CollisionShape createDynamicMeshShape(com.jme3.scene.Spatial spatial)

Create a hull shape for the given Spatial.

For mesh-accurate animated meshes (CPU intense!) use GImpact shapes.

Parameters:

spatial - the spatial on which to base the shape (not null)

Returns:

a HullCollisionShape (if spatial is a Geometry) or a CompoundCollisionShape with HullCollisionShapes as children (if spatial is a Node)

createBoxShape

public static CollisionShape createBoxShape(com.jme3.scene.Spatial spatial)

Create a box shape for the given Spatial.

Parameters:

spatial - the spatial on which to base the shape (not null)

Returns:

a BoxCollisionShape (if spatial is a Geometry) or a CompoundCollisionShape with BoxCollisionShapes as children (if spatial is a Node)

shiftCompoundShapeContents

public static void shiftCompoundShapeContents(CompoundCollisionShape compoundShape,
                                              com.jme3.math.Vector3f vector)

This method moves each child shape of a compound shape by the given vector

Parameters:

vector -
