[1.20.1] Adding Custom GUI with Slider on Top of Inventory GUI - Help with Implementation

[RatCommit]

Hi everyone,

I'm working on a mod where I need to display a custom GUI on top of the inventory screen that includes a slider. The goal is to allow the player to select a number using the slider, and then confirm the action, which will split an item stack (similar to shift-clicking, but with a custom number).

I've successfully created custom GUIs before using Screen, but I’m running into a couple of issues when trying to integrate a slider into the inventory screen (AbstractContainerScreen):

I found the slider in the forge package (net.minecraftforge.client.gui.widget.Slider), but I couldn’t find any usages or examples on how to properly implement it or use it in this context.

My Questions:

How can I properly integrate a slider into the custom gui screen ?

Is net.minecraftforge.client.gui.widget.Slider the right class to use for this?

If yes, are there any examples or recommended usages of this Forge slider widget?

If not, what would be a good alternative to create a custom slider (maybe extending AbstractSlider or another class)?

How do I ensure proper interaction between the slider and the rest of the inventory screen?

Any advice, code snippets, or examples would be greatly appreciated!

Thanks in advance for your help!
