2D Sprite position problem

Hi
I created 2d sprite image and my target is make it always Centered depend on screen resolution, i created the next small code but the 2d sprite disappear !! How fix it ?

Code (JavaScript):

1.  
2. function Update ()
3. {
4. transform.position = new Vector2(Screen.width/2, Screen.height/2);
5. }

 

Well, when you do this, the position.z value is getting set to 0. That could be the reason it seems to disappear if you're not looking at the correct depth.

Try this instead:

Code (CSharp):

1. function Update ()
2. {
3.     transform.position = new Vector3(Screen.width/2, Screen.height/2, transform.position.z);
4. }

Aside from that, I'm not sure why you would need to do this every single frame in Update(). If this is for some sort of UI, you're better off using a Canvas with an image anchored to the center.

 

sorry jeffreyschoch, the problem still live !
in the next screenshot it gone to these corrdinates:

 

I see, forgive me I should've noticed this before. In the unity game world, the units are not pixels unless your Pixels Per Unit is set to 1. By default it's 100. So by using Screen.width and Screen.height, you're getting a result in pixels.

You'll need to divide by your pixels per unit to make that work.

Or you'll have to convert to world like this:

Code (CSharp):

1. Vector3 worldPoint = Camera.main.ViewportToWorldPoint(0.5, 0.5);
2.  
3. transform.position = new Vector3(worldPoint.x, worldPoint.y, transform.position.z);

 

worked well, Thanks
