Python pygame sprite碰撞测试
我一直在学习一些pygame教程,并根据这些教程开发了自己的代码。详情如下:Python pygame sprite碰撞测试,python,pygame,collision-detection,Python,Pygame,Collision Detection,我一直在学习一些pygame教程,并根据这些教程开发了自己的代码。详情如下: #!/usr/bin/python import pygame, sys from pygame.locals import * size = width, height = 320, 320 clock = pygame.time.Clock() xDirection = 0 yDirection = 0 xPosition = 32 yPosition = 256 blockAmount = width/3

尝试使角色停止跳跃。是否有一个内置函数来测试这一点,或者在我的例子中是否有一种可行的方法。顺便说一下,这不起作用,我似乎不知道怎么做。非常感谢您的帮助:)代码的问题是,您的角色每一步移动的像素数超过一个。例如,当以最大速度移动时,角色每一步移动22个像素。因此,如果他一步高出草地10像素,那么下一步他将比草地低12像素。要解决此问题,请测试角色是否接触草地或在草地下,如下所示:
if mainCharacter.rect.bottom <= grass.rect.top:
jumping = False
如果mainCharacter.rect.bottom
if mainCharacter.rect.bottom <= grass.rect.top:
jumping = False
