我正在设计一款基于生存的游戏，但我无法让玩家从树上收集木材。
下面的函数检查我的鼠标是否被按下，如果玩家与任何树矩形碰撞，它们的木材数量就会增加一。我使用刻度来确保每九个刻度仅添加一根木头。
def check(self):
global tick
if pygame.mouse.get_pressed()[0]:
for tree in resources:
tree_rect=tree.rect
if self.rect.colliderect(tree_rect) and tick>=9:
self.inventory['wood']+=1
tick=0
但是，每当我单击时，有时会添加木头，有时则不会，无论我的玩家类别是否与任何树木发生碰撞。
我尝试使用pygame.sprite.spritecollide()，但结果是一样的。如有任何帮助，我们将不胜感激。

最佳答案
在Tree.update方法中绘制rect，您就会发现问题所在。
pygame.draw.rect(screen, (120, 50, 0), rect)
您使用 rect 的 x 和 y(topleft)坐标作为中心圆的点，因此矩形将位于树的右下象限。
= =
= =
= ____=___
= | = |
= | = |
= |= |
|________|
改用centerx和centery坐标:
pygame.gfxdraw.filled_circle(screen, rect.centerx, rect.centery, 80, light_green)
pygame.gfxdraw.aacircle(screen, rect.centerx, rect.centery, 80, light_green)
