Hello!
Quite weird and I know that there must be a super easy fix to the issue - or a configuration I’ve missed, but the problem is that the text element, the children of the default button created from the engine itself, is disappearing during runtime. I have zero idea, why that happens. As it does not happens with other text objects…
Above you can (low-key) see all of my settings - and the issue that I’m trying to fix…
Thanks for any input in advance!
Do you have any scripts referencing to this button and if so, can you share code of them?
Hey, thanks for the reply.
I have the prototype code in a more recent state, so please mind the code segments about keeping score etc.
But I guess the start method should be investigated (?)

Couldn’t find references to button’s text in your code. Maybe you accidently referenced text component in scene (you can check it by right-clicking component/object > Find References In Scene). Also as I can see your text containing object not deleted in runtime so check what happens to it.
No, you’re right, there are no references regarding its appearance, content or visibility.
Also, I cannot even add more elements to the Canvas as they are also becoming hidden in runtime. I’m switching between Render Modes for the canvas:
But they are giving different results - none of them are fully functional.
This is confusing…
There must be some layering problems but I’m not sure what to check out.
well, the first step is to create a new button and see if it disapears also
if not then start editing from the begin that button, until you reach the point where it disapears again, or if its fixed
happened many times to me. iirc it’s a matter of setting the wrapping correctly on your text.
or, button is simply too small for the text to fit in (and you have text’s wrapping set to Truncate). yeah, and in editor sometimes you get different results
Hey!
This is going to be crazy but… I’ve found the problem.
Even though I started up a 2D project (I never did in 3 years), it never occured to me that the depth of an asset, its position on the Z axis would be the key. These problems were coming from one item was being in front of another. This is super stupid on my side, but never thought that the 3rd dimension could confuse my 2D system…
I feel dumb.
dont sweat it, such things is business as usual, happens all the time to anyone
