A full-featured 2.5D rendering engine built with C++ and the SFML library. This project simulates a 3D environment by projecting rays through a 2D grid, inspired by the rendering techniques of classic games like Wolfenstein 3D.
- 2.5D Rendering: Real-time rendering of textured walls, floors, and ceilings.
- Level Logic: Includes 3 demo levels featuring:
- Kill Blocks: Tiles that reset the player upon contact.
- Win Blocks: Tiles that trigger a level completion.
- Interactive Doors: Functioning door mechanics via player interaction.
- Texture Converter: A built-in
BMP-to-Arraytool to prepare image data for the engine's pixel-by-pixel rendering pipeline.
The engine treats the game world as a 2D grid. To create the illusion of 3D, it casts rays from the player's position across their Field of View (FOV).
- Distance Calculation: The engine calculates the distance between the player and the first wall hit by a ray.
- Projection: Using the distance, the engine determines the height of a vertical slice to draw on the screen.
- Texture Mapping: The engine maps vertical strips of a texture array onto these slices.
To change the textures in the game, follow these steps:
- Open
Image.bmpand modify the graphics. Save it specifically as a BMP file. - Run
V-1\Converter\BMP_to_Array.exe. - The converter will translate the image into an array format required for the pixel-by-pixel renderer.
Note: Do not change the dimensions of individual texture blocks, as this will cause rendering misalignments.
