C# Sfml 我没有看到错误？

Question

我不知道为什么，但是我的跳转方法不起作用。我的角色只能跳到一个物体上。其他障碍对玩家没有任何影响。我真的没有看到我的错误

     foreach (RectangleShape obstacles in MoveAtObjectList)
               {
                   MainPlayer.Move(deltaTime, obstacles);
               }

               foreach (RectangleShape obstacles in JumpAtObjectList)
               {
                   MainPlayer.Jump(deltaTime, obstacles);
                   break;
               }

               Draw();

               Window.Display();
           }
       }
   }
}

这是我的主类的一部分，我在 foreach 循环中调用 jump 方法。在我的 Payer 类中，我尝试编写跳转函数。

看起来您在第一次迭代后打破了循环，这导致只执行第一次迭代：

foreach (RectangleShape obstacles in JumpAtObjectList)
{
    MainPlayer.Jump(deltaTime, obstacles);
    break;
}

从循环中删除 break 语句：

 foreach (RectangleShape obstacles in JumpAtObjectList)
 {
     MainPlayer.Jump(deltaTime, obstacles);
 }
