I wanna make the Dragon on the picture rotate softly to the left when he flys to the left and rotate to the right when he flys to the right and up and down also. enter image description here How can i do that with the keys w a s d? The Dragon can fly already up, down, lef, and right....but he don't turns...

My Code:

import pygame, sys
from pygame.locals import *


size = width, height = 1600, 848
speed = [2, 2]
black = (0, 0, 0)


screen = pygame.display.set_mode(size)
background = pygame.image.load("background.PNG")
dragon1 = pygame.image.load("dragon1.gif")
movex, movey=0,0

while True:
screen.blit(background, (0,0))
screen.blit(dragon1, (x,y))

for event in pygame.event.get():
    if event.type == QUIT:

if event.type==KEYDOWN:
        if event.key==K_a:
        elif event.key==K_d:
        elif event.key==K_w:
        elif event.key==K_s:
if event.type==KEYUP:
        if event.key==K_a:
        elif event.key==K_d:
        elif event.key==K_w:
        elif event.key==K_s:

Trying to circumvent the rules of the site, however, is a great way to guarantee your questions don't get viewed because they get closed.

Use pygame.transform.rotate function:

    screen.blit(background, (0,0))
    angle = None
    if movex == 0 and movey < 0:
        angle = -180
    elif movex > 0 and movey >= 0:
        angle = 20
    elif movex < 0 and movey >= 0:
        angle = -20
    elif movex > 0 and movey < 0:
        angle = 160
    elif movex < 0 and movey < 0:
        angle = -160

    if angle:
        dragon = pygame.transform.rotate(dragon1, angle)
        dragon = dragon1

    screen.blit(dragon, (x,y))

You can always keep the original surface dragon1 and transform it when you are going to blit it (like the example), or keep three variations pre-calculated and choose which one you want to blit.

  • \$\begingroup\$ sorry i'm just beginner but i tried it an it doesn't work...like your example.. \$\endgroup\$ – user2333167 Apr 29 '14 at 19:11
  • \$\begingroup\$ and what when de dragon flys up and down? \$\endgroup\$ – user2333167 Apr 29 '14 at 19:15
  • \$\begingroup\$ now it works but the dragon turns all the time i hold the key down...:( \$\endgroup\$ – user2333167 Apr 29 '14 at 19:24
  • \$\begingroup\$ Isn't it good? That while you are going right the angle is always the same? I'll add code for up and down too. \$\endgroup\$ – pmoleri Apr 29 '14 at 19:48
  • \$\begingroup\$ sorry what? if the dragon fly's left, he turns 20* but all the time until im stop holding the key...but he should turn only once he flys on one side... \$\endgroup\$ – user2333167 Apr 29 '14 at 19:52
