This got changed because switching weapons in EndPowerup is not safe - this can be called from weapon states where the player can end up with a different weapon being active than the one running the state.
The actual weapon switch has to be delayed until the state processing has ended.
A_OverlayPivotAlign(int layer, int halign, int valign)
- Aligns the pivot point origin to a corner of the PSprite before applying offsets.
- - halign: Horizontal. Applicable constants are PSPA_<LEFT/CENTER/RIGHT>.
- - valign: Vertical. Applicable constants are PSPA_<TOP/CENTER/BOTTOM>.
- - Default is top left.
A_OverlayVertexOffset(int layer, int index, double x, double y, int flags)
- Allows offsetting the corners of the psprite, granting modders the ability to skew weapon sprites as they see fit.
- - index: The index of the vertice. Valid ranges are between [0,3].
- - x/y: Offsets of vertices.
- - flags: Takes WOF_ flags.
Other changes:
- Removed pivot point interpolation since it's pointless.
- Removed PSPF_PIVOTSCREEN due to complications with it having relativity. This will be revisited either later or in another submission.
- Added ResetPSprite() to be called with BringUpWeapon(), A_Lower(), and morph weapon raising to reset all the new properties to 0.
Nearly ready now. Just some final testing needed.
