平滑旋转到一个角度

Question

我正在努力将一个物体旋转 160 度 degrees/second，然后让它在预先指定的角度减速到完全停止。例如，如果选择的角度是 30 度，它会旋转得很快，然后减速，最终停在 30 度处。我无法想出执行此操作的算法，这正是我所要求的。

暂时，假设您需要做的就是设置旋转 object.Rotation = 30（度）。随意写在 Java/Lua/C++/JavaScript.

目前我所掌握的（基本没有）：

//Assume that wait(1) waits 1 second
int angle = 70;//Fast rotations at first but slow down as time goes on
for (int i = 140; i > .1; i = i - 5)//Must work for every angle
{
    for (int a = 0; a < i; a = a + 10)
    {
        object.Rotation = a;
        wait(.05);
    }
}

Answer 1

伪代码：

int max_speed = 10
int target_angle = 30

while (target_angle != object.Rotation) do
  int delta = target_angle - object.Rotation
  delta = max(min(delta / 5, max_speed), -max_speed) + max(min(delta, 1), -1)
  object.Rotation = object.Rotation + delta
  wait(.05)
end while
