IDirect3DRMAnimation::AddPositionKey

HRESULT AddPositionKey(D3DVALUE rvTime, D3DVALUE rvX,

D3DVALUE rvY, D3DVALUE rvZ);

Adds a position key to the animation.

·Returns D3DRM_OK if successful, or an error otherwise. For a list of possible return codes, see Direct3D Retained-Mode Return Values.

rvTime

Time in the animation to store the position key. The time units are arbitrary and zero-based; a key whose rvTime value is 49 occurs exactly in the middle of an animation whose last key has an rvTime value of 99.

rvX, rvY, and rvZ

Position.
