大家好，我正在创建一个简单的2D游戏，到目前为止，我已经有一些噩梦试图让事情互相沟通。到目前为止，我有一个'主菜单'，'游戏网格'和一个显示在网格上的图像。我现在正在解决它的运动，但我似乎无法得到它的工作。JavaFx移动图像

它instantize到1级，当你打电话给你使用的是'你的键盘命令object.xPosition'你试图使用'object.setLayoutX = value'，也只需要注意，你已经使用函数来尝试返回一个你可以得到的值，而不需要把它放在一个函数中，例如'case W： keeper.setyPosition（keeper.getyPosition（）--KEYBOARD_MOVEMENT_DELTA）; break;' 可能只是'case W： keeper.setyPosition（keeper.getLayoutY（） - KEYBOARD_MOVEMENT_DELTA）; break;'不需要功能。 – TravisF
谢谢你们两位的回复，非常友善。 你会推荐我在哪里放置object.setLayoutX = value方法？ – SteveMunroe
您需要将它们放到您的级别类中，因为这是WarehouseKeeper对象被实例化的地方（当它被赋予一个地方并且它需要成为一个节点时），可以将该命令发送到另一个类，但是为了保持它的整洁，你只需在与之类似的类中进行操作，如果你阅读下面的答案，那么你的答案大部分都是正确的，你只需要改变你的键盘记录器就可以使用你的关卡类中的实例化对象。 – TravisF
