As of version 1.12 - 14.21.1.2436, this feature is now included in forge. This mod will no longer work properly or even cause crashes. This project will only stay up as a reference for other modders.

Replaces the advancements screen with a new gui that supports multiple pages for advancements

The vanilla advancement screen only supports 26 advancement tabs. Thats why :P

This mod consists of 2 parts that are bundled into one jar. The biggest part is a coremod which is getting assisted by a really small FML mod. This means, the mod is currently not compliant to the Forge Coremod Policy! I will work on that as soon as possible, but at the moment, forge does not support loading coremods from embedded jars and I dont want to ship the coremod + a single classfile mod separately.

This is a coremod(😱) that modifies the GuiScreenAdvancements class:

• Adds a public integer field selectedPage to the class which can be set from outside sources (in this case a GuiEvent handler)
• Patches the rootAdvancementAdded method to call GuiAdvancementsTabEx.createEx() instead of GuiAdvancementsTab.create() which handles the calculation of the page and index on the page
• Patches the drawScreen() method to call super.drawScreen() to allow the use of buttons on the Gui

The rest of the logic is handled by the GuiAdvancementsTabEx which just extends GuiAdvancementsTab and adds some paging logic. Rendering the paging buttons as well as the switching logic is handled in the GuiEventHandlerAdvancementScreen, so I dont have to add more ASM patches to the GuiScreenAdvancements class :)~~
