NEED HELP: Custom Widget Slider

Using Enhanced Input System.

I’m trying to make my own slider (SizeBox-based), with Step and Drag and Drop functionality to work for both Mouse and Gamepad.

Problem is that Menu is not receiving ANY Mouse Input, unless I hold the LMB down around the viewport.

Also, on top, when I interact with List Item that has a slider, so I can grab it (indirectly / activate it), the scalar ceases to update completely, preventing me from updating its value.

I’m losing my mind looking for a fix.

Okay, bumping this to give more info on it.

For Pseudo-Experts:

Sliders use these mechanics:

  • Drag and Drop: Slider Moves based on if it’s active, button is held and mouse/stick is moved in X direction (scalar).
  • Step: Uses arrow buttons to change the value of the slider, if available.

Visually it updates between Normal of 0.0 to 1.0.
In my case between 382,5 and 27,0.

0.0 = 27,0

1.0 = 382,5

I wanted to make my own, using Sizebox as a bar for the slider, that is clamped between Min and Max Lenght.

Problem is, which I already mentioned, that the input from the mouse is completely ignored, until I hold down the button outside the list item.

And when I interact with my List Item, activating/grabbing the Slider owned by it, my mouse/stick scalar is not received/updated at all.

Am I asking “too complex” questions?

The window/viewport is not capturing mouse movement input, unless I hold down the LMB button (mouse cursor disappears, while doing so)!
