Good, Maybe this is a complicated thing for beginners like me, but just in case someone wants to do the same as me, here I leave this little tutorial.
Basically I’m creating a character creator and I was doing something cool in the widget to select the color. I had created a “radial slider” with the transparent bar to let you see the texture with a radial RGB color image. (Everything I’m going to say is using a vector color value inside a “Material Parameter Collection” (which is a kind of global variable of only one color, something that I find very useful to tint anything: widgets, character textures…) "I had transformed the texture to a radial RGB color image. …)) "I had transformed the slider value into RGb thanks to the “HSV to RGB” and I had taken the color value and passed it to the “Print text” node so that both the RGB values and the color itself would appear tinting the text on the screen. The result was a kind of rainbow of text that was printed on the screen. I liked it so much that I wanted to put it inside the Widget itself.
Well, I did it by creating a “scrol box” in my widget to which, every time I changed the value of the “radial slider” I would add a “child” inside (the “child” is, simply, a widget with text inside that has the
text and color variables). Remember to click on the little buttons!
Everything worked fine, but the problem was that the number of “Childs” was infinite and the scrol box only showed the first “Childs” instead of the last ones. So something had to be done to eliminate the first ones, constantly to make room for the next ones. My original idea was to remove them after 0.2 seconds, but what happened was that it always removed the last one added, so it was stuck.
So I decided to make an “array” list of widgets so that it would constantly delete the ten widgets in the list as it replenished them.
Explaining it step by step would be a bit redundant if you have the image to see it, but remember how to make an array of “user widget”.
First the variable is searched for and then it is specified as “array”.
Nothing else, I hope you find it useful.
