您好，我目前正在制作一款生存射击游戏，但找不到任何关于如何进行碰撞的方法!我试图让玩家与地板碰撞，但没有成功。这是 map 的图像(我想与月球 block 碰撞): /image/R2apz.jpg
这是一张没有背景的月球 block 图像: /image/W9H2m.png
最后这是我的代码:

最佳答案
我为 PyWeek #17 制作了一款非常类似的游戏，名为“Miner”。 这是屏幕截图:http://media.pyweek.org/dl/17/powrtoch/miner_ss.png (你可以看到相似之处!)
您可以在 GitHub 上找到相关代码:https://github.com/marcusmoller/pyweek17-miner/blob/master/miner/engine.py#L202-L220 :
def checkCollision(self, sprite, xVel, yVel):
for x in range(len(level.levelStructure)):
for y in range(len(level.levelStructure[x])):
block = level.levelStructure[x][y]
if block is not None:
if pygame.sprite.collide_rect(sprite, block):
if xVel < 0:
sprite.rect.x = block.rect.x + block.rect.w
if xVel > 0:
sprite.rect.x = block.rect.x - sprite.rect.w
if yVel < 0:
sprite.rect.y = block.rect.y + block.rect.h
if yVel > 0 and not sprite.onGround:
sprite.onGround = True
sprite.rect.y = block.rect.y - sprite.rect.h
