問題描述
球在傾斜平面上滾動 java libgdx (Ball rolling on an incline plane java libgdx)
我正在嘗試編寫自己的物理程序（請不要使用 box2d 的答案），並且我想要一個球在它接觸的任何傾斜平面上滾動。我在物理學方面擁有豐富的經驗，但由於某種原因，我似乎無法在任何地方找到如何在任何地方進行編程。非常感謝任何有關如何解決此問題的幫助！
參考解法
方法 1:
Think geometrically!
First you need to find out if and which plane the ball touches. Create a vector from the balls position that points straight down. Find the nearest plane this vector intersects. This can be done with vector math, e.g. the basics you find in wiki: https://en.wikipedia.org/wiki/Line%E2%80%93plane_intersection
You now know the plane and you can calculate the distance between ball and plane intersection point. If the distance is <= balls radius, it touches. From there, calculate the planes slope and modify the balls movement vector accordingly (to your physics model).

From the very limited information you've given it looks like a duplicate of 3D libgdx rotation, for which you can find an example as well at https://gist.github.com/xoppa/3b841fb52f46e8cdec24
