function calls in python (pygame)

Question

im trying to split my code into functions and i want to input my own values for x and y. so the character can move from the inputed values. When i try to do this from the function call, nothing happens.

Any suggestions?

import pygame, sys
from pygame.locals import *

pygame.init()

width,height=(842,595)
screen = pygame.display.set_mode((width,height),0,32)
pygame.display.set_caption("game")
man = pygame.image.load("man.png")
target = pygame.image.load("star.png")

#setting a background image
bgimage= pygame.image.load("background.jpg")
##image for the jupiter object
another_target = pygame.image.load("jupiter.gif")


x = 100
y = height-300

another_targetx = 400
another_targety = 500

#allows movement whilst holding down key.

clock= pygame.time.Clock()

def move(x,y):
    movingX =0
    movingY =0

    speedX =0
    speedY=0
    while True:
        pygame.display.update()  
        for event in pygame.event.get():
            if event.type==QUIT:
                pygame.quit()
                sys.exit()
            elif event.type==KEYDOWN:
                if event.key ==K_LEFT:
                    x-=5
                elif event.key==K_RIGHT:
                    x+=5
                elif event.key==K_UP:
                    y-=5
                elif event.key==K_DOWN:
                    y+=5

        time_Passed=clock.tick(25)
        time_elapsed_seconds=time_Passed/1000.0

        distanceX = time_elapsed_seconds*speedX
        movingX+=distanceX

        distanceY=time_elapsed_seconds*speedY
        movingY+=distanceY

        x+=movingX
        y+=movingY
        clock.tick(50)
    pygame.display.update()  

move(x,y) 
screen.blit(bgimage,(0,0))
screen.blit(man, (x,y))
screen.blit( another_target,( another_targetx, another_targety))
screen.blit(target,(200,400))
pygame.display.update()

You should really work on your question titles. calling functions python (pygame), function calls python (pygames) and function calls in python (pygame) are not really helpful :-) — sloth

You have an infinite loop within the command move(x, y). The stuff on the outside of this loop which updates the screen is never reached, so nothing ever appears to happen. Try putting everything after the command definition into the while True loop inside the command.
