[SOLVED] Add element to world list without editing base classes!

[Rexozz]

Hey folks!

 

I want to add an element to the vanilla world list!

But I don't know how to do that without editing some base classes!

Can someone help me please?

add an element to the vanilla world list!

 

What?

[Rexozz]

I want to add text behind the name of the world!

[Draco18s]

Oh. You're trying to add another line of text to the screen that lets you pick a world to play (the "load a save" screen).

 

The not-coremod way of doing this would be to create your own GUI screen and replace it when the vanilla one is invoked (there's events for that).

 

This probably isn't the best way (COG does stuff in a way that's a holdover from when another person was maintaining it, all I did was make sure that it continued to work on 1.10--also that code only adds a button to the "create new world" screen rather than replacing the entire GUI).

Whoahh, thank you so much!

Actually, that would be so easy if I wouldn't think so complicated!

First I tried to do it with java reflection! How stupid can I be?

 

You probably do not need to replace the whole GuiScreen.

Is there another way to achieve this?

[Rexozz]

 

Like this one!

I decided to do this with images instead of text.

[Rexozz]

Ok I'll try this!

Unfortenately my #*!#?!*%## brandnew Computer died today so it will take a while to post results!

But thank you diesieben07 and Draco18s ^^

[Rexozz]

Yeahhhhh, got my computer to work!

 

Now this is my result:

 

Everything works perfectly! Thanks ^^

 

EDIT: If someone else has problems with this:

1. Copy the classes GuiWorldSelection, GuiListWorldSelection and GuiListWorldSelectionEntry to your mod and edit the drawEntry method in the GuiListWorldSelectionEntry class

2. Create an class that does this:

You can easily draw additional stuff onto an existing

GuiScreen

using

GuiScreenEvent.DrawScreenEvent

(you could also use the InitGuiEvent like I, depends on what you want to do! When the events are called is really self-explanatory)

And register the event in your client proxy or client side in your main mod or common proxy init method!

3. Here's the source for the event class:

Don't know if there's an easier way but I hope it helps ^^
