I can’t find anything around that has an answer to this so forgive me if I’m just missing something here.
I’m just trying to change a UI image on button press. I have it set up similarly in a different project and it works there but in this one it isn’t working at all. I’m using the node ‘Set Brush’ but ‘Set Brush from Texture’ doesn’t work either.
On begin play I’m creating a reference to the widget in question that has the image I’m trying to change:
Then on button press I set a stat, then check if the stat is a certain number before changing the image. I have also tried just straight button press = change image, neither worked. I have tried both Set Brush and Set Brush from Texture and neither are working.
It has to be in the viewport to change the image? Hmm how do I change an image in a widget without it being in the viewport?
For example, this one’s a stat screen the player pulls up with a button press, I want the image to change without the widget being active at the time so that it can happen while the stat screen is not up.
The stat page is shown by pressing TAB, there are a set of stars (1 star, 2 star, etc) for each stat. I want to be able to press a button to change the amount of stars (change the image) when the stat page is not visible, so that when the player presses TAB to view their stats they are now different.
For example if I interact with something in the world that changes the stats and adds a star, I want to then be able to pull up the stat page and see that there is one more star added. This has to happen without the widget being in the viewport/visible.
There’s no guarantee the Create Widget node keeps referencing the widget. You should reference it the same as in the 1st pic and then use that ref - so other entities can access that referenced instance.
Ah shoot, okay you learn something new about this program every day! Sorry I’m still quite new to all this. So if this widget is only created when the button is hit, how would I reference it to change the image from before the first time it is created with TAB?
About the connection not being safe- if I want it on a flipflop and the second half to remove it from parent, how would I do that then without doing what I did?
If I do that in the TAB script, won’t it not have a reference made until the first time the player hits TAB? So if they never hit TAB and interact with something that is supposed to change the stars, nothing would happen no?
One note, adding to viewport reconstructs the widget - if you have any script there, it will be rerun and the widget laid out again. Could be irrelevant here but another way to go about it is to keep the widget in the viewport, but keep it hidden. Tab would show / hide it instead.
You can validate references by right clicking pins, like so:
