Method Details

getLocalTransformNoScale

public Mat44 getLocalTransformNoScale(Vec3Arg scale)

Calculate the local transform for this shape, given the scale of the child. The sub-shape is unaffected.

Parameters:

scale - the scale of the child in the local space of this shape (not null, unaffected)

Returns:

a new transform matrix

getPositionCom

public Vec3 getPositionCom()

Copy the center-of-mass location. The sub-shape is unaffected. (native function: GetPositionCOM)

Returns:

a new vector

getRotation

public Quat getRotation()

Copy the rotation. The sub-shape is unaffected.

Returns:

a new rotation quaternion

getShape

public ConstShape getShape()

Access the child shape. The sub-shape is unaffected.

Returns:

a new JVM object with the pre-existing native object assigned

isValidScale

public boolean isValidScale(Vec3Arg scale)

Test whether the specified scale is valid for the sub-shape. The sub-shape is unaffected.

Parameters:

scale - the scale factors to validate (not null, unaffected)

Returns:

true if valid, otherwise false

setPositionCom

public void setPositionCom(Vec3Arg location)

Alter the center-of-mass location. (native function: SetPositionCOM)

Parameters:

location - the desired location (not null, unaffected)

setRotation

public void setRotation(QuatArg rotation)

Alter the rotation.

Parameters:

rotation - the desired rotation (not null, unaffected)

setTransform

public void setTransform(Vec3Arg offset,
 QuatArg rotation,
 Vec3Arg centerOfMass)

Alter the coordinate transform.

Parameters:

offset - the desired translation (not null, unaffected)

rotation - the desired rotation (not null, unaffected)

centerOfMass - the desired center of mass (not null, unaffected)

transformScale

public Vec3 transformScale(Vec3Arg scale)

Transform the specified scale to the local space of the child.

Parameters:

scale - the scale to transform (not null, unaffected)

Returns:

a new vector
