单位在最小和最大距离之间旋转 [英] unity Rotate between min and max distance

问题描述

我正在尝试拖动一个对象.该对象只能旋转这么多. (Similair到门).

I'm trying to make it possible to drag an object. This object can only rotate so much. (Similair to a door).

这是对位进行编辑的代码，该代码旋转有效的对象. 我有2个向量用于最大旋转和最小旋转.

Here is the code abit edited that rotates an object which works. I have 2 vectors for maxrotation and minrotation.

每当用户拖动可交互对象时，就会调用此代码. (例如更新，但仅在拖动时显示)

This code will be called whenever the user is dragging the interactible object. (like update but only when dragged)

        if (GestureManager.Instance.IsNavigating &&
    HandsManager.Instance.FocusedGameObject == gameObject)
        {
            //speed and navigiation of rotation
            float rotationFactor;
            rotationFactor = ManipulationManager.Instance.ManipulationPosition.y * RotationSensitivity;
            totransform.Rotate(new Vector3(rotationFactor, 0, 0));
        }

如果我可以在这里使用if语句，那将是很棒的.我尝试了很多事情，但仍然无法正常工作.

It would be great if I could use an if statement here. And I tried quite some things but it's still not working.

如前所述，此处的代码粘贴有效.该对象应该是可拖动的，但只能拖动到一定程度.

As stated the code paste here works. The object should be dragable but only up to a certain points.

totransform是要旋转的变换

totransform is the transform that will be rotated

任何想法都将是伟大的，并且将受到赞赏.

Any ideas would be great and most appreciated.

亲切的问候.

推荐答案

我认为您想看看

I think you want to look at eulerAngles. Check the values you're getting then set an if-statement before doing the rotation. This is a sample code for you to find the values you want:

if (GestureManager.Instance.IsNavigating &&
    HandsManager.Instance.FocusedGameObject == gameObject)
{
    //speed and navigiation of rotation
    float rotationFactor = ManipulationManager.Instance.ManipulationPosition.y * RotationSensitivity;

    Debug.Log(totransform.eulerAngles);
    if (totransform.eulerAngles.x < 100) {
        totransform.Rotate(new Vector3(rotationFactor, 0, 0));
    }
}
