Sets the velocity of the given frame relative to the reference frame. The frame will be moved by the vector [rvX, rvY, rvZ] with respect to the reference frame at each successive call to the IDirect3DRM::Tick or IDirect3DRMFrame::Move method.
HRESULT SetVelocity(
LPDIRECT3DRMFRAME lpRef,
D3DVALUE rvX,
D3DVALUE rvY,
D3DVALUE rvZ,
BOOL fRotVel
);
Parameters
lpRef
Address of a variable that represents the Direct3DRMFrame object to be used as the reference.
rvX, rvY, and rvZ
New velocity for the frame.
fRotVel
Flag specifying whether the rotational velocity of the object is taken into account when setting the linear velocity. If TRUE, the object's rotational velocity is included in the calculation.
Return Values
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible return codes, see Direct3D Retained-Mode Return Values.
