Java LWJGL仅在俯仰和偏航时向前移动
所以基本上在我的游戏中，我设法添加了向右移动，然后应用了相反的逻辑向左移动，但我仍然无法向前或向后移动。 我只有一个俯仰和偏航的工作， 意思是我没有旋转X，Y或Z。 如果你能帮我计算这些，如果必要的话也会很酷。 这是我目前的代码：Java LWJGL仅在俯仰和偏航时向前移动,java,math,opengl,vector,lwjgl,Java,Math,Opengl,Vector,Lwjgl,所以基本上在我的游戏中，我设法添加了向右移动，然后应用了相反的逻辑向左移动，但我仍然无法向前或向后移动。 我只有一个俯仰和偏航的工作， 意思是我没有旋转X，Y或Z。 如果你能帮我计算这些，如果必要的话也会很酷。 这是我目前的代码： 公共级摄像机{ 专用最终浮动最大螺距=90.0F； 私有向量3f位置=新向量3f（0,0,0）； 私人浮球； 私人浮球； 私人浮动偏航； 私人浮动汇率； 私人浮动辊； 专用浮球前进速度=7.0f； 私人浮动后退速度=10.0f； 专用浮动侧速度=反向速度； 专用浮动跳
