造成此问题的原因是，
pygame.Rect存储整数坐标：
Rect对象的坐标都是整数。[…]
的部分组件
dx，并
dy当你丢失：
self.Rect.x += dxself.Rect.y += dy
您必须以浮点精度进行计算。在类中添加一个
xand
y属性。递增属性
move并同步
Rect属性：
class Player: def __init__(self, color): self.Rect = pygame.Rect([50, 50], [30, 50]) self.x = self.Rect.x self.y = slef.Rect.y # [...] def move(self, dx, dy, platforms): # Test for collisions with platforms # handle movement on the X axis self.x += dx self.Rect.x = round(self.x) for platform in platforms: if self.Rect.colliderect(platform.Rect): if dx > 0: self.Rect.right = platform.Rect.left if dx < 0: self.Rect.left = platform.Rect.right self.x = self.Rect.x # Reset velocity when collision with wall self.vx = 0 # handle movement on the Y axis self.Rect.y += dy self.Rect.y = round(self.y) for platform in platforms: if self.Rect.colliderect(platform.Rect): if dy > 0: self.Rect.bottom = platform.Rect.top if dy < 0: self.Rect.top = platform.Rect.bottom self.y = self.Rect.y # Reset velocity when collision with floor or roof self.vy = 0 # return correctly collided rect to draw() return self.Rect
