Moving A Sprite To The Other Side When A Sprite Moves Off Screen Pygame

If I have a sprite (See below) that I can move around, the screen with the arrow keys. (Up and Down moves forwards and backwards, left and right turn.) I was wondering if it would

Solution 1:

I'm not too familiar with pygame but I think this game (md5: 92f9f508cbe2d015b18376fb083e0064 file: spacegame.zip) has the feature you're looking for. Thanks to the author, DR0ID_ , for making it publicly available on his/her website

To implement the "wrap around" feature in your car game I used this function from "game.py":

def draw(self, surface):
    wrap = 0for s inself.sprites():
        r = s.rect
        if r.left<0:
            r.move_ip(800, 0)
            wrap = 1
        elif r.right > 800:
            r.move_ip(-800, 0)
            wrap = 1if r.top < 0:
            r.move_ip(0, 600)
            wrap = 1
        elif r.bottom > 600:
            r.move_ip(0, -600)
            wrap = 1ifwrap:
            surface_blit(s.image, r)
            wrap = 0

After a few adjustments I ended up with this working example:

import sys, pygame, math
from pygame.locals import *
pygame.init()

# Added HEIGHT and WIDTH as fixed variables 

WIDTH = 800
HEIGHT = 600

SCREEN = pygame.display.set_mode((WIDTH, HEIGHT))

car = pygame.transform.scale(pygame.image.load('Car.png').convert_alpha(), (64, 64))
pygame.display.set_caption('Car Game')
pygame.display.set_icon(car)
FPS = pygame.time.Clock()

carX  = 400
carY  = 100
angle = 90
speed = 0whileTrue:

    if angle == 360: angle = 0if  angle == -1: angle = 359

    SCREEN.fill((0,0,0))

    foreventin pygame.event.get():
        ifevent.type == QUIT:
            pygame.quit()
            sys.exit()

    keys = pygame.key.get_pressed()
    if keys[K_a] or keys[K_LEFT]:
        angle += speed
    elif keys[K_d] or keys[K_RIGHT]:
        angle -= speed
    if keys[K_w] or keys[K_UP]:
        speed += 1
    elif keys[K_s] or keys[K_DOWN]:
        speed -= 0.5

    carX += speed*math.cos(math.radians(angle))
    carY -= speed*math.sin(math.radians(angle))
    speed *= 0.95

    rotcar = pygame.transform.rotate(car, angle)
    position = rotcar.get_rect(center = (carX,carY))

    # Basically a copy/paste of the "draw"-functionfrom the spacegame.zip

    wrap_around = Falseif position[0] <  0 :
        # off screen left
        position.move_ip(WIDTH, 0)
        wrap_around = Trueif position[0]  + rotcar.get_width() > WIDTH:
        # off screen right
        position.move_ip(-WIDTH, 0)
        wrap_around = Trueif position[1]  < 0:
        # off screen top
        position.move_ip(0, HEIGHT) 
        wrap_around = Trueif position[1] + rotcar.get_height() > HEIGHT:
        # off screen bottom
        position.move_ip(0, -HEIGHT) 
        wrap_around = Trueif wrap_around:

        SCREEN.blit(rotcar, position)


    position[0] %= WIDTH
    position[1] %= HEIGHT  
    carX %= WIDTH
    carY %= HEIGHT


    SCREEN.blit(rotcar, position)

    pygame.display.update()
    FPS.tick(24)

Solution 2:

Instead of using "elif"-statements, you can just set the coordinates "modulo" (%) screen-width / screen height, for x and y coordinates individually.
