Migrate ROTT to SDL3 - #20
Conversation
This commit completes the migration of the ROTT engine from SDL2 to SDL3. Key changes include: - Graphics: Updated window and renderer creation in `modexlib.c`. Moved to `SDL_CreateSurface` and `SDL_BlitSurfaceScaled`. - Input: Updated event handling to use the SDL3 event structure in `rt_in.c`. Migrated from `SDL_GameController` to `SDL_Gamepad`. - Audio: Refactored the audio backend to use the new `SDL3_mixer` Track-based API. This included a major overhaul of `fx_man.c` and `audiolib/dsl.c`, including a PCM-to-float conversion in the mixing callback. - IO: Replaced all occurrences of `SDL_RWops` with `SDL_IOStream` and updated related filesystem functions. - Build System: Updated `rott/Makefile` and `rott/audiolib/Makefile` to use `pkg-config` for dependency management. - Compatibility: Resolved type conflicts with the project's internal `boolean` type and SDL3's use of `stdbool.h`. All modifications are restricted to the `rott/` directory. Build artifacts have been excluded. Co-authored-by: h4mu <603324+h4mu@users.noreply.github.com>

I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

@jules how did you build this? I'm seeing lots of build errors on Ubuntu 25 |
I built SDL3 and SDL3_mixer from source since they aren't standard in most repos yet. Here is the process I followed:
If you're seeing specific errors, they might be related to missing development headers for dependencies that SDL3 requires. |
- Removed accidentally added SDL/SDL_mixer submodules from the root directory. - Restored MIDI music functionality in `dukemusc.c` using the new SDL3_mixer Track-based API. - Confirmed and implemented the correct `MIX_` prefix for SDL3_mixer functions and types. - Cleaned up redundant includes and unnecessary defines in `fx_man.c`. - Fixed warnings related to unused variables and pointer signedness. - Updated `rott/Makefile` to correctly link the game with SDL3 and SDL3_mixer using pkg-config. All changes are now strictly confined to the `rott/` directory. Building with `make` inside `rott/` is verified to work. Co-authored-by: h4mu <603324+h4mu@users.noreply.github.com>

Implement a GitHub Actions workflow to automate multi-platform builds (Windows, Linux, and Android) for the Shareware, SiteLicense, and SuperROTT editions. Update the Linux build process to bundle SDL3 runtime dependencies and configure RPATH, ensuring the executable can find its libraries when installed. - Create `.github/workflows/release.yml` to handle automated packaging and GitHub release publishing. - Update `rott/CMakeLists.txt` with installation rules and dependency resolution for Linux.
Includes project modules, SDK settings for Android API 36, and Git VCS mappings for SDL and SDL_mixer dependencies.
- Update game file paths in README to reflect flavor-specific package names - Document transition to SDL3 and unified Gradle/CMake build system - Upgrade Java version from 11 to 17 in the release workflow
