Finding a GameObject using a canvas text?

Questions & Answers
1

I just don’t understand it. I used to use guitext and managed to muddle through with that.
I’ve got a canvas, called “Canvas” and a text ui element called “text” – think these are the defaults.

With javascript, I just want to be able to affect the value of the text shown.
How do I do this? I’ve googled and tried to use their examples, but I either get an error of just nothing happens.

Please help. Tearing my hair out over what should be so, so so simple.

The “Text” component has a property called “text”

That’s the one you need to change.

var myTextObject : GameObject;

//Assign your object

myTextObject.GetComponent <Text> ().text = "Your text here."

Not solved. What I’m trying to do is to find a gameobject (in this case, text with a specifc name in a canvas).

var myDescText : GameObject;
 myDescText = GameObject.Find("NotifyText");

 // for the purposes of this question, the variable myLitem contains a string "redmist"
// so, with this line, the text of the gameObject called 'NotifyText' should be changed to 'redmist' right?
  myDescText.GetComponent <Text> ().text = myLitem;

Except it doesn’t work and spits out 3 errors all pointing to the last line of my code.
These errors are:

Assets/scripts/switchscript.js(65,35): BCE0043: Unexpected token: ).

Assets/scripts/switchscript.js(65,36): BCE0044: expecting ), found ‘.’.

Assets/scripts/switchscript.js(65,37): UCE0001: ‘;’ expected. Insert a semicolon at the end.

Please can someone see where I’m going wrong and offer corrections as needed.

You can use Javascript but just use it right.

var myDescText : GameObject;
function Start () {
   myDescText = GameObject.Find("NotifyText");
   if(myDescText != null){
       var text : Text = myDescText.GetComponent (Text);
       if(text !=null){
             text.text = "testing"; 
       }
   }
}

The null checks are not required but you can also add some debug to see if something goes wrong.
