如何将画布和TextMeshPro垂直保持在字符上方

Question

我制作了Canvas和TextMeshPro，然后制作了这个立方体对象的子对象。

    GameObject myCanvas = new GameObject();
    myCanvas.name = "TestCanvas";
    myCanvas.AddComponent<Canvas>();
    Canvas canvas = myCanvas.GetComponent<Canvas>();
    canvas.renderMode = RenderMode.WorldSpace;
            

    GameObject myText = new GameObject();
    myText.name = "wibble";
    myText.transform.parent = myCanvas.transform;
    myText.AddComponent<TextMeshPro>();
    TextMeshPro text = myText.GetComponent<TextMeshPro>();
    text.text = "Ta-dah!";
    text.fontSize = 12;
    //text.font = (Font)Resources.Load("MyFont");
    myCanvas.transform.parent = cube.transform; // attache canvas as child of cube.

但是，到目前为止，当多维数据集轮回文本时，它仍然有效。

我想保持文字始终略高于字符沿Y轴，即使当旋转发生。

我该怎么做？？

Answer 1

我会在画布游戏对象中添加一个Billboard组件来处理旋转，并使画布始终面向摄像机。

公告牌部分：

使用UnityEngine；

public class Billboard : MonoBehaviour {
    public Transform cam;
    private void Start() {
        cam = Camera.main.transform;
    }
    void LateUpdate() {
        transform.LookAt(transform.position + cam.forward);
    }
}

使用myCanvas.AddComponent<Billboard>();添加组件，整个脚本如下：

    GameObject myCanvas = new GameObject();
    myCanvas.name = "TestCanvas";
    myCanvas.AddComponent<Canvas>();
    Canvas canvas = myCanvas.GetComponent<Canvas>();
    canvas.renderMode = RenderMode.WorldSpace;

    myCanvas.AddComponent<Billboard>(); //component added here

    GameObject myText = new GameObject();
    myText.name = "wibble";
    myText.transform.parent = myCanvas.transform;
    myText.AddComponent<TextMeshPro>();
    TextMeshPro text = myText.GetComponent<TextMeshPro>();
    text.text = "Ta-dah!";
    text.fontSize = 12;
    //text.font = (Font)Resources.Load("MyFont");
    myCanvas.transform.parent = transform; // attache canvas as child of cube.

编辑:旋转立方体的图像与画布正面进入照相机。
