Please see "demos/ObjRotation" for an example program.
|
Clone a Rotation/Scaling Set. The hel_ObjRotScaleClone function clones an existing Rotation/Scaling Set.
|
|
Create a new Rotation/Scaling Set. The hel_ObjRotScaleCreate creates a new Rotation/Scaling Set and returns a Handle to it.
|
|
Deinitialize Object Rotation/Scaling SubSystem. Call hel_ObjRotScaleInit to deinitialize the Rotation/Scaling Parameter SubSystem. |
|
Delete a Rotation/Scaling Set.
The hel_ObjRotScaleDelete deletes the Rotation/Scaling Set specified by
|
|
Get amount of free Rotation/Scaling Sets. The hel_ObjRotScaleGetFreeSlots returns the amount of free/unused Rotation/Scaling Sets. |
|
Initialize Object Rotation/Scaling SubSystem. Call hel_ObjRotScaleInit once to initialize the Rotation/Scaling Parameter SubSystem. This function must be called before using any other Object Rotation/Scaling function. |
|
Reset Object Rotation/Scaling SubSystem. The hel_ObjRotScaleReset resets the Object Rotation/Scaling SubSystem. |
|
Transmit Rotation/Scaling Parameters to hardware. The hel_ObjRotScaleTransmit forces the Rotation/Scaling SubSystem to copy its shadowed parameters to hardware (Vram). This function should be called during Vertical Blank. |
|
Update Rotation/Scaling Parameters. hel_ObjRotScaleUpdate can be used to update the parameters of an existing Rotation/Scaling Set. This includes the rotation-angle and zoom.
