Constructor Detail

GImpactCollisionShape

public GImpactCollisionShape(CompoundMesh mesh,
                             Vector3f offset)

Instantiate a shape based on the specified CompoundMesh and offset.

Parameters:

mesh - the mesh on which to base the shape (not null, unaffected)

offset - the offset to add to the vertex positions (not null, unaffected)

GImpactCollisionShape

public GImpactCollisionShape(IndexedMesh... submeshes)

Instantiate a shape based on the specified native mesh(es).

Parameters:

submeshes - the mesh(es) on which to base the shape (not null)

Method Detail

countMeshTriangles

public int countMeshTriangles()

Count how many triangles are in the mesh.

Returns:

the count (≥0)

countMeshVertices

public int countMeshVertices()

Count how many vertices are in the mesh.

Returns:

the count (≥0)

countSubmeshes

public int countSubmeshes()

Count how many submeshes are in the mesh.

Returns:

the count (≥0)

getSubmesh

public IndexedMesh getSubmesh(int index)

Access the specified submesh.

Parameters:

index - the index of the desired submesh (in the order the submeshes were added, ≥0)

Returns:

the pre-existing instance (not null)

split

public ChildCollisionShape[] split(Triangle splittingTriangle)

Attempt to divide this shape into 2 shapes.

Parameters:

splittingTriangle - to define the splitting plane (in shape coordinates, not null, unaffected)

Returns:

a pair of children, the first child generated by the plane's minus side and the 2nd child generated by its plus side; either child may be null, indicating an empty shape

canSplit

public boolean canSplit()

Test whether the shape can be split by an arbitrary plane.

Overrides:

canSplit in class CollisionShape

Returns:

true

recalculateAabb

protected void recalculateAabb()

Recalculate this shape's bounding box if necessary.

Overrides:

recalculateAabb in class CollisionShape

setScale

public void setScale(Vector3f scale)

Alter the scale factors of this shape.

Note that if the shape is shared (between collision objects and/or compound shapes) changes can have unintended consequences.

Overrides:

setScale in class CollisionShape

Parameters:

scale - the desired scale factor for each local axis (not null, no negative component, unaffected, default=(1,1,1))
