How to make a simple 3d game (Raycaster) in Scratch. This update episode can be slotted in anywhere after episode 2 and gives us a huge speed boost in our bitmap raycasting speeds! You won't believe it - I didn't!!! We also add an FPS counter, and implement framerate independent movement for the player and enemies in the game.
With the extra speed we have achieved we are all set to now look at adding texture mapping! I hope you are ready for some serious fun!
