Question by bstout · Oct 03, 2016 at 07:44 PM · canvasinstantiate prefabparent and child

UnityEngine.Canvas' does not contain a definition for `FindWithTag'

I am trying to instantiate a text object stating the new score when and where an object dies. I can instantiate the object but I can not see it in the game view until it is parented to the canvas. That's where the trouble begins.

private Canvas canvas;

     void Start()
 {
     pos = transform.position ;
     Canvas thisCanvas = Canvas.FindWithTag("canvas");
     canvas = thisCanvas.GetComponent<Canvas>();
 }

public void killBubble () {

     Destroy(gameObject);
     ScoreManager.score += scoreValue;
     Instantiate (scoreText, pos, Quaternion.identity);
     scoreText.transform.parent = canvas.transform;
     }


how can i find the canvas to make it a parent of the instantiated text object?

thanks in advance for your help

The syntax is GameObject.FindWithTag or gameObject.FindWithTag. You are using [Component].FindWithTag.

You can do this ins$$anonymous$$d

 void Start()
 {
     pos = transform.position;
     GameObject go = GameObject.FindWithTag("canvas");
     canvas = go.GetComponent<Canvas>();
 }

This does require that your canvas is tagged as canvas (case sensitive).

There may be another way, but I always use:
GameObject.FindGameObjectWithTag("myTag")
or
GameObject.FindWithTag("myTag")
(same function)

 GameObject myCanvas = GameObject.FindWithTag("Canvas");
 myTextGameObject.transform.SetParent(myCanvas.transform);

Should get the object tagged "Canvas" and set myTextGameObject as a child. You shoudn't need to get the canvas component to parent it, since it's always paired to a GameObject.
