平滑的角色旋转

这是我在四个基本方向上移动的代码：

    if (Input.GetKeyDown(KeyCode.RightArrow)){
        transform.forward = new Vector3(0f, 0f, 1f);
        }
    else if (Input.GetKeyDown(KeyCode.LeftArrow)){
        transform.forward = new Vector3(0f, 0f, -1f);
        }
    else if (Input.GetKeyDown(KeyCode.DownArrow)){
        transform.forward = new Vector3(1f, 0f, 0f);
        }
    else if (Input.GetKeyDown(KeyCode.UpArrow)){
        transform.forward = new Vector3(-1f, 0f, 0f);
        }

我的角色立即在四个行进方向上旋转我遇到的问题是试图弄清楚如何在方向之间平滑。我想说的是，如果角色指向北，并且您按下按钮向西走，我希望看到角色向西方向平滑地旋转一定角度，而不是立即转向西。

我搜索并尝试了教程，但没有一个起作用。有什么解决办法吗？

Here is my code for moving in the four cardinal directions:

    if (Input.GetKeyDown(KeyCode.RightArrow)){
        transform.forward = new Vector3(0f, 0f, 1f);
        }
    else if (Input.GetKeyDown(KeyCode.LeftArrow)){
        transform.forward = new Vector3(0f, 0f, -1f);
        }
    else if (Input.GetKeyDown(KeyCode.DownArrow)){
        transform.forward = new Vector3(1f, 0f, 0f);
        }
    else if (Input.GetKeyDown(KeyCode.UpArrow)){
        transform.forward = new Vector3(-1f, 0f, 0f);
        }

My character instantly rotates in the four directions of travel The problem I'm having is trying to figure out how I can smooth out inbetween directions. What I'm trying to say is, if the character is pointing north and you push the button to go west, instead of instantly turning west, I would like to see the character rotate smoothly in degrees to the westward direction.

Ive search and tried tutorials, but none of them worked. Any solution?

看一下 Slerp 函数。这可能会做你想要的。

http://unity3d.com/support/documentation/ScriptReference/Quaternion.Slerp.html

简单的例子：

    newdir.y=-135; // depends on which axis you want to turn...

transform.rotation = Quaternion.Lerp(transform.rotation, newdir, Time.deltaTime * smoothSpeed);

所以你基本上得到了当前旋转的四元数。将其复制到新的四元数中，并增加或减少一个或多个轴上的旋转。

Take a look at the Slerp function. This will probably do what you want.

http://unity3d.com/support/documentation/ScriptReference/Quaternion.Slerp.html

Simple example:

    newdir.y=-135; // depends on which axis you want to turn...

transform.rotation = Quaternion.Lerp(transform.rotation, newdir, Time.deltaTime * smoothSpeed);

So you basically get the Quaternion of your current rotation. Copy that in a new Quaternion and increase or decrease the the rotation on one or more axis.
