这就是基本函数:
def xCollision(self):
for tile in tiles:
if tile.colliderect(self.rect):
if self.x_vel >= 1:
self.rect.right = tile.left
elif self.x_vel <= -1:
self.rect.left = tile.right
def yCollision(self):
for tile in tiles:
if tile.colliderect(self.rect):
if self.y_vel >= 1:
self.rect.bottom = tile.top
elif self.y_vel <= -1:
self.rect.top = tile.bottom
在Player类中。
现在，当我尝试这个我的帧下降到大约4帧每秒，它也不工作。关于它不工作它需要对self。rect。something = tile做点什么。因为当我用print()替换它时，它会打印任何东西
这里是完整的代码供参考，是的，我刚刚开始，所以不要认为它会有什么好，好吗?
