Need help on making raycasting faster

[robie972003]

ok thank you ill go do that now

---

Its getting faster! I just need find an alternative to "break" because the loop needs to end immediately if the statement is true. anyway here is the updated code, I changed the whole thing up a bit.

import turtle
import math
import pygame
pygame.init()
pygame.display.set_mode()
events = pygame.event.get()

colors = {1: "Blue", 2: "Mediumblue", 3: "Red", 4: "Crimson"}

# Instructions:
# UP = forward
# LEFT = left
# RIGHT = right
# DOWN = backwards
# Do not run into the walls partly because I haven't coded the collision
# detection and also partly because it displays an error right after
