我正在製作遊戲，並且遇到碰撞檢測問題。我正在製作關卡塊的結尾，但是它無法檢測到玩家是否站在關卡上以更改爲2級。該塊的碰撞檢測可以在player.updater（）中找到。除此之外，該塊是一個類，並且位於稱爲endPlatform的組中，以允許碰撞檢測工作。遊戲運行完美，但無法檢測到玩家何時碰到Endplatform。我沒有得到任何出現的錯誤。碰撞檢測不能在pygame中工作
EndPlatform：

self.image = pygame.image.load("endPlatform.png")
self.rect = self.image.get_rect()
display.blit(self.image, self.rect)

確保塊和播放器的矩形值正確設置並相互碰撞。據我所知，你沒有設置結束塊的X/Y座標。 – ventsyv
我在Level_01類中設置x和y座標，我確定我也是爲Player做的。 – Fabmaur
你能輸出玩家的座標嗎？此外，嘗試明確設置碰撞檢測函數（pygame.sprite.collide_rect（））作爲spritecolide的第四個參數 – ventsyv
