OPack2Reload

📖 Introduction

Minecraft always loads some base resource packs such as:

• vanilla (the game's default resources)
• mod_resources (resources added by mods)

However, before the player opens the resource pack screen for the first time, the game's options.txt still records resourcepacks=[] as empty.

So when opening the resource pack selection screen before creating or joining a world, even if the player does nothing (no adding, removing, or reordering), clicking "Done" or pressing Esc will still cause Minecraft to incorrectly think new resource packs were added, and it will forcibly reload them.

This reload process can be very slow, especially when many modded resource packs are involved.

✅ What This Mod Does

This mod introduces two features to avoid this unnecessary waste of time:

1. If the user hasn’t made any actual changes to the resource pack list, pressing Esc or clicking “Done” will no longer trigger a reload.

2. An extra "Cancel" button was added to the resource pack screen, intended to exit without triggering any logic at all.
   (However, after 1.20, due to technical limitations in Minecraft, resource pack validation always runs when the screen closes, making the Cancel button behave nearly the same as Done in most cases.
   As a result, the Cancel button was removed in the 1.21.1 NeoForge version.)

The additional "Cancel" button:
