[1.11 - ~Solved] Using GuiListExtended

[Franckyi]

Hi !

I'm still working on my "Item Editor" mod for mapmakers. I'm working on a simple way to add enchantments to an item, so I created a list of all enchantments in Vanilla Minecraft.

I created my enchant list by extending

GuiListExtended

and my list items by implementing

IGuiListEntry

.

Everything seems to be working well, except the scroll bar. I did nothing about it and I don't know how it works. I can't find any tutorials on Internet.

I can give you source codes if you need.

Can someone help me ?

Ok then, there you have the source code :

 

 

My GuiScreen :

My GuiListExtended :

}

@Override

Edit : Lol, when I posted the code I saw I always used 'Minecraft.getMinecraft()' instead of 'mc' in my GUIs ^^ Let's fix that

 

[Franckyi]

Ok, I found how to register scroll buttons. But I want to scroll the list using the scroll bar or the mouse wheel.

Does someone know how to do that?

[Franckyi]

My bad, didn't know that GuiScrollingList exists.
