Rend

This is the same as my Raycasting repo but you can se this in any project and it is sorta a module.

To use this module you need to have the Rend folder inside where you want to use it.

Then you need to import pygame

Then initialize the screan

And also make a map(The layout of what you render):

  _ = False
  mapp = [	[[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
               [1, _, _, 1, _, _, _, _, _, _, _, _, _, _, _, 1],
               [1, _, _, 1, _, _, _, _, _, _, _, _, _, _, _, 1],  
               [1, _, _, 1, _, _, _, _, _, _, _, _, _, _, _, 1],
               [1, _, _, _, _, _, 1, _, _, _, _, _, _, _, _, 1],
               [1, _, _, _, _, _, 1, _, _, _, _, _, _, _, _, 1],
               [1, _, _, _, _, _, 1, _, _, _, _, _, _, _, _, 1],
               [1, _, _, _, _, _, 1, _, _, _, _, _, _, _, _, 1],
               [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]],
    ]

Then initialize the folowing classes:

  cam = Rend.camera()
  rend = Rend.object_renderer(screan)      
  map = Rend.map()      
  map.update()      
  ray = Rend.raycasting()      
  clock = pygame.time.Clock()

Then we need to add our layout to the map class:

  map.import_map(mapp)

later we need to make the game loop

Finaly call these methods:

cam.movement()    
obj = {}    
for i in range(len(map.world_map)):    
obj[i] = ray.ray_cast(map.world_map[i], cam)	
rend.get_objects_to_render(obj, map.world_map)    
rend.draw()

#Example code:

import Rend

import pygame

_ = 0
mapp = [	[[1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
	     [1, _, _, 1, _, _, _, _, _, _, _, _, _, _, _, 1],
	     [1, _, _, 1, _, _, _, _, _, _, _, _, _, _, _, 1],
	     [1, _, _, 1, _, _, _, _, _, _, _, _, _, _, _, 1],
	     [1, _, _, _, _, _, 1, _, _, _, _, _, _, _, _, 1],
	     [1, _, _, _, _, _, 1, _, _, _, _, _, _, _, _, 1],
	     [1, _, _, _, _, _, 1, _, _, _, _, _, _, _, _, 1],
	     [1, _, _, _, _, _, 1, _, _, _, _, _, _, _, _, 1],
	     [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]],
	]
pygame.init()
screan = pygame.display.set_mode((Rend.settings.WIDTH, Rend.settings.HEIGHT))
cam = Rend.camera()
rend = Rend.object_renderer(screan)
map = Rend.map()
map.import_map(mapp)
map.update()
ray = Rend.raycasting()
clock = pygame.time.Clock()

running = True
while running:
    pygame.display.set_caption(str(int(clock.get_fps())))
    screan.fill((0, 0, 0))
    for event in pygame.event.get():
	if event.type == pygame.QUIT:
	    running = False
    cam.movement()
    obj = {}
    for i in range(len(map.world_map)):
	obj[i] = ray.ray_cast(map.world_map[i], cam)
    rend.get_objects_to_render(obj, map.world_map)
    rend.draw()
    pygame.display.flip()
    clock.tick(Rend.settings.FPS)
pygame.quit()
