i used

if (GetComponent<Renderer>().isVisible)
 {
    //Visible code here
 }
 else {
    //Not visible code here
 }

but when i start game, not visible code is executing itself two times, but my object is still visible.

I wouldn’t use that…
I think in editor it check all the cameras, which might be problematic.
And you shouldn’t probably do GetComponent in every Update… cache that to some field.

Also - when posting code, always use code tags, here is how:

Using code tags properly

If you see someone who needs to know about code tags, please link them to this post: Please use code tags when posting code. You can “tag” your code by typing [984347--130826--Screenshot 2015-03-16 10.33.58.png] around your code. There is no overt “Code” tag button that automatically tags a selection as code. That being said, however, we can Insert code directly into the post using the “Insert Code” button: [image] This will bring up an “Insert” window were we can paste our code and choose…

You can edit you message with that edit button…

I would use this instead:

screenPos = myCamera.WorldToViewportPoint(transform.position);

Then simply check if your position is less than 0 or more than 1 in either x or y.

should i this code put to my object’s script?

“should i this code put to my object’s script?”

I didn’t give some cut and paste code… if you know the basics, you should pretty much be able to use that without much effort.

I think you should visit https://learn.unity.com/ and watch some tutorials.

You can place code where it fits best in your code. It could be in object, or in some other object depending on what you are trying to do. Which you didn’t explain to begin with.
