Can't get an actual canvas size

Questions & Answers

Hi, guys!

I can’t figure out how to get the actual size of a canvas. Here is the canvas in the inspector: [87698-безымянныи.jpg|87698]

so you can see that its width and height are 901.2876 to 600. How can I access these values via script? When I tried several functuons, neither of them provided me a needed result. Here is the code I’ve used and its result:

void Awake()
	{	
		var rect = canvas.transform as RectTransform;

		Debug.Log ("sizeDelta: " + rect.sizeDelta);
            // sizeDelta: 350; 233

		Debug.Log ("canvas width: " + rect.rect.width + "; canvas height: " + rect.rect.height);
            // canvas width: 350; canvas height: 233

		Debug.Log ("scale factor: " + rect.localScale);
            // scale factor: (1.0, 1.0, 1.0)

		Debug.Log ("Screen size: " + Screen.width + "; " + Screen.height);
            // Screen size: 350; 233

		Debug.Log (Screen.currentResolution);
            // 1920 x 1080 @ 60Hz

            Debug.Log ("scale factor " + canvas.scaleFactor);
            // scale factor 1
	}

As you see, most functionl provide me the “350 : 233” size. If I divide it by the scale factor shown in inspector (see the image above), which is equal to 0.3883, I will get the correct result. But when I try to get this value by the rect.localScale functions, it provides me just a unit vector (1; 1; 1). Why? Why the scale factor is 1, when it should be 0.3883? What should I do?

Put your logic in to the start function and you will get desire result. In awake canvas scaler component doest not rendered yet so you cannot acces correct rect size.
