- Setting WOF_INTERPOLATE on any of the functions with flags (except A_OverlayFlags) will enable one tic for interpolating.
- Setting PSPF_INTERPOLATE with A_OverlayFlags will permanently enable it for that layer, but requires manual calling.
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.
- Fixed PSPF_PIVOTPERCENT not being applied at start by default.
- Pivots now start in the upper left corner. Alignment flags are planned next for pivot point starting.
Significant progress made, but more testing still required.
- Fixed A_OverlayPivot carrying over copying of X to Y if Y is zero. This is meant to be exclusive to A_OverlayScale only.
- Added WOF_ZeroY to prevent copying X to Y for A_OverlayScale when desired, mirroring A_SetScale's behavior.
The idea behind this is to outright remove the relative position adding from the engine side and let it happen with A_OverlayOffset instead. Still more work to do.
All decisions were done deep inside the texture creation code, leaving zero options to the higher level code for controlling the feature.
Changed this so that the option to upscale must be passed as a parameter to FRenderState::SetMaterial and extended all needed variables to manage the added texture variants.
Still not solved: Material layers need explicit control, not only for scaling but also for filtering.
It makes little sense exposing every minute detail of this through UDMF.
Setting it up that way is far too complicated. Using virtual textures that map to a real texture plus a colorization record should be far easier to use by mappers.
This also doesn't piggyback on the Doom64 color feature anymore and is completely separate, despite some redundancies.
This is still missing the texture definition part, though.
