PixelPerfectEngine

PixelPerfectEngine is a (currently) 2D engine written in D, which is specifically made for creating authentic pixel-art graphics without misalignment, etc.

Features:

• Color lookup and palette swap effects.
• Sprite layer with horizontal and vertical scaling, complete with the shimmering typical of old systems.
• Tile layer with optional per-line scrolling.
• Transformable tile layer (Mode7)
• Input handling (currently via SDL2).
• Has its own map format to support its own features, editor is capable of importing CSV tile maps.
• Graphical User Interface (Concrete), influenced by old GUIs (Amiga Workbench, Win3.1, etc). Primarily made for its own editors (e.g. PixelPerfectEditor), but probably could be used for games too.
• Text formatting support via a custom XML (ETML) file format, single file is capable of holding multiple text chunk in one.
• Bitmap text drawing with variable width.
• Audio subsystem that runs its own "plugins" (modules) for effects and sound synthesis.

  
  

  • QM816 - phase modulation engine capable of replicating digital FM synthesis sounds, alongside with some extra capabilities (user-definable wavetables, amplitude/ring modulation for things like resonance, greater feedback control, etc.).
  • PCM8 - PCM playback module, which is capable of playing back 8 and 16 bit PCM, IMA ADPCM, Dialogic ADPCM, Mu-Law and A-Law PCM.
  • DelayLines - adds delay and reverb effects.
• MIDI sequencer.
• Editors:
  • PixelPerfectEditor - Editor for tilemaps, sprite placement, etc.
  • test1/PPE Audio Development Kit - Module routing, presets, etc. (MIDI 2.0 editing will be added later on).
  • WindowMaker - Window layout editor.

Coming later:

• Moving some of the rendering to the GPU, which will enable more complex sprite transformations, and even 3D (background tiles will likely still be rendered on the CPU).
• Scripting in some form (once I'm finding a suitable replacement for Lua).
• Language and localization support.
• More audio modules.
• MIDI 2.0 file support (likely have to invent my own format).
• Guide on setting up a D development environment.
