UMG Sliders (need help)

Development Programming & Scripting Blueprint

Hi,

I’m creating a mini game that involves sliders and I am unable to figure out how to achieve the result I am looking for.

The slider can go from 0 to 1 and the goal is to find the correct value by moving the slider, for example, 0.3 . As I the slider value reaches the threshold of 0.2 I want to gradually change a material parameter, for example, opacity. Once it reaches 0.3 in this case the opacity should be at 1 but once the slider value is greater than 0.3 I want the opacity to decrease until it reaches 0.4.

I am stuck because I don’t know how to get the direction of the slider (if I am increasing or decreasing slider value). My idea was to store old slider value as a variable and then compare with the current slider value but how do I set the old value so that it wouldn’t be equal to the current slider value? Or maybe there is a better way?

Thanks

I figured it out by using Map Range Clamped node.

I think it would work better if you used curves. This is what a curve might look like based on your description:

848×609 39.9 KB

And here is how you get the curve value:

Thanks for the advice! I’ll remember it in the future but for now I made a macro that converts the range of 0.2 - 0.3 into a range of 0 - 1 and range 0.3 - 0.4 into 1 - 0 which is basically the same.
