[Pygame]：将表面移向位置

Question

Is there an algorithm to change a set of coordinates to make it move towards another set of coordinates? Like, if I have ax,ay=(20,30) a

 #fonctions import pygame, sys from pygame.locals import * pygame.init() fpsClock = pygame.time.Clock() windows= pygame.display.set_mode((1200,500), 0, 32) pygame.display.set_caption('testing') size = width, height = (32, 32) PNGImg = pygame.Surface(size) sob_X=575 sob_Y=250 FPS = 15 # frames per second setting RED= (255, 0, 0) #red color while True: windows.fill((54, 141, 197)) pygame.draw.circle(windows, RED, (70, 80), 20, 0) windows.blit(PNGImg, (sob_X,sob_Y)) dis_X=sob_X-600 #cicle X_Cordinate dis_Y=sob_X-870 #cicle Y_Cordinate if dis_X<0: sob_X=sob_X+ dis_X if sob_X==70 and dis_Y<0: sob_Y=sob_X+dis_Y elif sob_X==70 and dis_Y>0: sob_Y=sob_Y-dis_Y elif dis_X>0: sob_X=sob_X -dis_X if sob_X==70 and dis_Y<0: sob_Y=sob_Y+dis_Y elif sob_X==70 and dis_Y>0: sob_Y=sob_Y-dis_Y windows.blit(PNGImg, (sob_X,sob_Y)) for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() pygame.display.update() fpsClock.tick(FPS) pygame.quit()

nd bx,by=(40,60)

How can I change ax and ay (coordinate of the image"surface") to equal bx and by? (Preferably an algorithm achievable in python.) i tried to make algorithme but in the end don't work thanks you

Answer 1

Replying here as I can't comment yet, but from the question itself, do you mean to do ax, ay = bx, by ? You can simply do that, or even individual ones like ax = by .

With an example from the terminal:

>>> ax,ay=(20,30)
>>> bx,by=(40,60)
>>> ax, ay = bx, by
>>> ax, ay
(40, 60)
