Scroll View Issue

[mholmes]

I’m having a scroll view issue:

I remember seeing this along time ago but i don’t remember the solution

[mholmes]

no one has a solution?

[Brathnann]

I don’t understand what you’re trying to show. Is your text enlarged? What are you showing in the first screenshot?

[mholmes]

That’s what happens when I bring data in from my API. It even happens when I split the text. I’ve split it down to just a few letters and it still wants to mess up. I seen this once but not sure how they fixed it.

[Brathnann]

However you are populating your scroll rect, do those objects have a layout element on them?

[mholmes]

Assuming your asking about the content part:

[Brathnann]

Nope, asking about how you’re adding stuff to the content. You need layout elements on those items since you’re using a vertical layout group.

[mholmes]

Not sure I understand

[mholmes]

I added a layout element to my text object and now I get nothing. Its giving me an error that I have handing elements or something? Just trying to add dynamic text to a scroll view content. .Do you have a video or tut on how to add a simple Game object such as text to a scroll view?

error:

Updated code but now I get nothing:

            }
        }

        {
            Debug.Log(ex);
            Debug.Log("Failed To Get News");
        }

        yield return _dtNews;
    }
}

If you’re getting nothing, chances are your dtNews has no data by the time you hit your loop.
However, your problem is most likely a scaling issue. When you instantiate an object and assign it’s parent, it usually isn’t scaled properly. So just set it’s scale it Vector3.one and that might be all you need to fix it. If you select the instantiated object in your hierarchy after it’s added to your scrollview, is it scaled up really large?

[mholmes]

I figured it out. So my code above works but I had to put it on the content object its self for this to work on a scroll view. Prior, I had everything on an object and imported the scroll view content etc.
