Constructor Details

MutableCompoundShape

public MutableCompoundShape()

Instantiate an empty compound shape with no subshapes.

Method Details

addShape

public int addShape(Vec3Arg offset,
 QuatArg rotation,
 ShapeRefC shapeRef)

Add a subshape in the specified position.

Parameters:

offset - the desired offset (not null, unaffected)

rotation - the desired rotation (not null, not zero, unaffected)

shapeRef - a reference to the desired subshape (not null)

Returns:

the index of the added subshape

adjustCenterOfMass

public void adjustCenterOfMass()

Recalculate the center of mass and shift the subshapes accordingly.

removeShape

public void removeShape(int index)

Remove the specified subshape.

Parameters:

index - the index of the subshape to remove (≥0)
