Create a new surface for each 'usemtl' statement in the OBJ file, and fix memory errors caused by TriangulateQuad.
Calculate missing normals, and fix incorrect UV coordinates
Fix construction of vertex buffer for objects with multiple surfaces
Localize curMtl, curSurface, aggSurfFaceCount, and curSurfFaceCount to FOBJModel::Load(), since they are not used anywhere else.
Fix parsing of OBJs without UV references
Internally, I replaced hashtag line comments with C-style line comments, and I replaced each forward slash with newSideSep.
If no UV coordinates are available, add a default vector of (0,0).
Also, remove "this->" from ResolveIndex to make the code a bit cleaner, and fix a minor garbage issue I failed to notice earlier (normref would pick up garbage if there was no normal reference).
Ensure usemtl statements remain intact
It may be a bit inefficient, but I tried modifying the buffer directly, and I got memory corruption errors. In this case, it's a lot better to be safe than sorry.
What works:
- Parsing the model
- Constructing geometry (surfaces) for triangulated models
What doesn't:
- Rendering the model
- Building the vertex buffer
- Triangulating quads
RIndexOf returns the index where the substring starts, instead of the index where the substring ends - 1.
Deprecate the LastIndexOf method of StringStruct
This setup has been a constant source of problems so now I reviewed all uses of FName to make sure that everything that needs to be initialized is done manually.
This also merges the player_t constructor into the class definition as default values.
These methods do not examine or change playsim state. They only perform math or look at class metadata.
Methods changed are:
• deltaangle
• absangle
• AngleToVector
• RotateVector
• Normalize180
• BobSin
• GetDefaultSpeed
• FindState
• GetDropItems (which changes the scope of the returned struct, but the returned struct is all-readonly anyway)
The logic here was a bit more complicated than I assumed but it was all buried in a heap of code that tried to deal with angular wraparounds in the BAM format.
When GZDoom 3.5.0 was released, the ZScript version in the release commit was set to 3.5.0, but on master it was left at 3.4.0.
In the future, I suggest setting the ZScript version *before* making a release commit. Then master will remain up to date.
This reverts commit 8c7d3b6ab8.
With DTA_LegacyRenderStyle being added there is no pressing need for this. Aside from that there's an utterly unhealthy amount of information duplication here and it is missing some more recent additions.
