- GetTerrainDef takes the raw number of the Terrains[] index. Can return null.
- GetFloorTerrain (Sector) gets the defs from the position given (either Sector.Floor or Sector.Ceiling).
- Offset: The offset from the actor's view to move the camera about.
- Flags: (Default is -1, which means don't change flags)
- VPSF_ABSOLUTEOFFSET: Don't include actor angles in calculation.
- VPSF_ABSOLUTEPOS: Position is absolute, and disables all transformations. Modders are responsible for being portal aware!
Notes:
- `ViewPos` in Actor will be `null` until A_SetViewPos is called for the first time.
**Issues:**
- Hiding sprite while in portal incomplete.
- 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 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.
There were two booleans that could be merged into the flag word.
This also fixes a bug with CHAN_NOSTOP not working for local sounds because it checked the wrong sound source for the playing sound.
- added Marisa Kirisame's CHAN_OVERLAP flag.
- exported S_IsActorPlayingSomething to ZScript.
The sound API change required deprecating A_PlaySound and S_Sound. There are now new variants S_StartSound and A_StartSound which have two distinct parameters for channel and flags.
There are two options here - one only disables the vertical thrust and the other goes back fully to the original non-z-aware code.
Both options are settable through MAPINFO.
For the compatibility presets, the normal ones only disable the vertical thrust, the strict ones force use of the old code entirely.
