I want to make a scrollable list of buttons (which then edits the itemstack in an slot), but I really dont know where to begin... Any hints or something?

 

Thanks

Buttons (Gui) are client-side only. Aside from that fact - you shouldn't give players ability to change stuff on client.

Aside from that, if feature is for creative mode only - you don't need to worry about anything since creative player is allowed (by vanilla itself) to change ItemStacks (updates don't go server->client, but are bipolar).

 

So after thinking about the design, now how to actually code gui:

Consider updating to at least 1.7.10 as I don't know if 1.7.2 has methods/classes I'm gonna mention.

 

First of all, look into vanilla or forge's option menu - talking about controls.

If you wan't to know how stuff works or code more flexible stuff - look into GuiScrollingList or GuiListExtended.

All that should be put into GuiScreen.

 

And as I always tell - Gui is something that can't have tutorial for all cases. Vanillas code and time are your allies.

 

Why not update?

Why does it need to be scrollable? Because you have lots of them?

 

Anyway, the general idea is that you would create a class that extends GuiScreen. Then in the initGui() method you would create all the buttons. You would also have fields to remember the amount of scrolling. in the drawScreen() method you would then draw the buttons in a position based on the amount of scrolling. To control the scrolling you could look at other GUIs that have slider scrolling, or you could create "up" and "down" buttons. If you created buttons for the scrolling then you would handle the actionPerformed() method and adjust the scroll amount based on which button was pressed. In the updateScreen() method, for any button that is scrolled far enough to go off the screen, you would set visible to false.

 

That's pretty much the idea -- just keep track of the scroll and draw the buttons locations according to the amount of scrolling.

Thank you both very much; I think I can try and do something with this information..
