RwSetUserDrawParentAlignment(RwUserDraw *userdraw, RwUserDrawAlignmentTypes alignment);
Description
Sets the alignment flags of the user-draw’s parent. A user-draw’s parent is either the bounding box of the clump that owns the user-draw or the current camera’s viewport.
The alignment flags of the user-draw’s parent determine which part of the user-draw’s parent rectangle is aligned with the user-draw. The actual point of alignment between a user-draw and its parent is determined by the user-draw’s alignment flags and the parent’s alignment flags.
Arguments
userdraw Pointer to the user-draw.
alignment A bitfield representing an alignment flag (or "bitwise or" of flags).
Return Value
The argument userdraw if successful, and NULL otherwise.
Comments
If the user-draw’s type is rwBBOXALIGN then the user-draw’s parent is the bounding box of the clump to which the user-draw is attached. If the type is rwVPALIGN the user-draw’s parent is the viewport of the current camera when the user-draw is rendered. If the user-draw’s type is rwVERTEXALIGN or rwCLUMPALIGN then the user-draw has no parent and the parent alignment bitfield is ignored.
The alignment flags are:
• 0 Align with the center of the parent.
• rwALIGNTOP Align with the top edge of the parent.
• rwALIGNBOTTOM Align with the bottom edge of the parent.
• rwALIGNLEFT Align with the left edge of the parent.
• rwALIGNRIGHT Align with the right edge of the parent.
