Java 玩家角色移动错误LibGDX RPG
我正在做一个RPG游戏，但是，我现在有一个错误。玩家的角色可以在所有四个基本方向上移动，但是如果你向右、向上或向下移动，玩家就会被卡住 此外，该错误似乎有一定的逻辑性： 如果向下移动，角色将卡在向下移动的循环中 除非按下向上箭头，否则玩家将开始一个新的向上无限循环 除非按下向右箭头，否则玩家将开始一个新的向右无限循环 所以权利似乎优先于向上，而向上优先于向下 奇怪的是，向左移动的效果非常好。即使角色卡在无限循环中，左箭头键也会使玩家以正确的方式向左移动 我不明白代码中的错误在哪里。我不知道为什么向左移动有效，而其他三个方向无效。我不明白为什么其他三个方向之间似乎也有某种优先顺序 我已经看过了整个程序，我认为我对待向左运动的方式和对待其他方向的方式没有什么不同。然而，考虑到这个错误，我可能是错的 由于30k字的限制，我没有足够的空间来包含这里的所有代码。因此，我包含了一个指向github的链接，因此您可以在那里看到代码 我认为这些课程可能是最重要的课程：Java 玩家角色移动错误LibGDX RPG,java,libgdx,Java,Libgdx,我正在做一个RPG游戏，但是，我现在有一个错误。玩家的角色可以在所有四个基本方向上移动，但是如果你向右、向上或向下移动，玩家就会被卡住 此外，该错误似乎有一定的逻辑性： 如果向下移动，角色将卡在向下移动的循环中 除非按下向上箭头，否则玩家将开始一个新的向上无限循环 除非按下向右箭头，否则玩家将开始一个新的向右无限循环 所以权利似乎优先于向上，而向上优先于向下 奇怪的是，向左移动的效果非常好。即使角色卡在无限循环中，左箭头键也会使玩家以正确的方式向左移动 我不明白代码中的错误在哪里。我不知道为什么
