Question

这是我的剧本：

var ctexture : Texture2D;
function Update() {
var ray = Camera.main.ScreenPointToRay (Vector3(Screen.width/2,Screen.height/2,0));
var hit : RaycastHit;
if (Physics.Raycast (ray, hit, 100)) {
    var pointVec=Camera.main.WorldToScreenPoint(hit.point);
    GUI.Label(Rect(pointVec.x,pointVec.y,145,93),ctexture);
    Debug.DrawRay (ray.origin, ray.direction * 10, Color.yellow);
Debug.Log(hit.point);}}

我可以看到Debug.DrawRay光线，它就是我想要它的方式。问题是我无法看到GUI.Label的结果。分配了ctexture，Debug.Log打印出正确的信息。

提前致谢。

将代码放在OnGUI（）函数中：

var ctexture : Texture2D;

function OnGUI() {
    var ray = Camera.main.ScreenPointToRay (Vector3(Screen.width/2,Screen.height/2,0));
    var hit : RaycastHit;
    if (Physics.Raycast (ray, hit, 100)) {
        var pointVec=Camera.main.WorldToScreenPoint(hit.point);
        GUI.Label(Rect(pointVec.x,pointVec.y,145,93),ctexture);
        Debug.DrawRay (ray.origin, ray.direction * 10, Color.yellow);
        Debug.Log(hit.point);
    }
}
