# Variable explanations:
# HEIGHT = window height
# line_height = calculated height of line (from raycast)
# pixels = amount of pixels to draw (to prevent drawing off-screen or wasting time)

pixels = int(min(HEIGHT, line_height))
draw_start = int(HEIGHT // 2 - pixels // 2)

# Loop through pixels
for y in range(pixels):
    # Get texel Y
    texel_y = (wall_width - 1) * ((y - (pixels - line_height) / 2) / line_height)

    # Draw pixel (using PyGame's pixel array)
    pixel_array[x, draw_start + y] = wall_image_pil[texel_x, texel_y]  # texel_x is calculated earlier and doesn't have any problems
