A 2.5D Raycasting Game Engine

A brand-new, old-school game-engine inspired by the likes of Wolfenstein 3D (1992) and Ultima Underworld: The Stygian Abyss (1992). Uses simple raycasting techniques and a uniform cell grid to render 3D.

Currently in Phase 4:

• Levels are represented in memory as Jagged Arrays (to save memory)
• Wall and Floor maps are just CSV's (So I can quickly make levels in Excel)
• Wall and Floor textures are represented by char's so I can very quickly make maps with a variety of textures
• Wall/Floor file io

TODO

• Remake / Demake a Pokemon town in this engine
• Texture animations
  • Src directory
  • Frames (must have at least 1)
  • Store current frame index tracker
  • Frame rate
  • Looping
  • Random start frame
  • Random frame order
• Texture transparency (ray pass-through to next texture)
• texture collision enabled bitfield for floor wall or ceiling via 0bXXX (similar to texture surface type) so you can have hotbox detection for walls, floors, and ceilings
• Sprites are all square/rectangular like minecraft and always face the player, but can "change direction" by changing the texture currently displayed
• Separate drawing/raycasting logic from window width and height

Previous phases

Phase 3

• Fixed visual artifacts and pixel densities

Phase 2

• Wall collision detection
• Basic texture mapping for walls
• Very warped tetures with many artifacts

Phase 1

• Very basic ray-casting
• No collision detection
