This is an old-school DDA raycaster made in Windows Batch. This project is notable for its functionality despite Batch's lack of floating point arithmetic or built-in trigonometric functions.

Per Batch's limitations, frames take roughly 1.5 seconds to generate and movement is done via console-inputs (set /p).

Designed exclusively for Windows. Functionality within Linux/macOS virtual environments may vary (e.g. wine).

1. Modify map.txt to contain the map of your choice. By default, the character '·' middle-dot, U+00B7, denotes empty cells.
2. Double click raycaster.bat or execute from Command Prompt.
3. Movement/aiming commands relative to the top-down map
   3.1 w=north, a=west, s=south, d=east
   3.2 z #=aim left, x #=aim right, where # is the number of degrees to turn.

NOTE: Run optimized/raycaster_optimized.bat instead of raycaster.bat for greatly increased performance at the cost of unreadable code.
