About TaCZ Pack Upgrader

From Modrinth

Only required on unofficial TaCZ 1.21.1

TaCZ Pack Upgrader

This mod is completely unrelated if you're using the official TaCZ Automatically upgrades the gun packs to be compatible with TaCZ 1.21.1

Basic Usage

  1. Install the mod
  2. Put the gun packs into the tacz folder as usual
  3. Launch the game and the packs will be upgraded and loaded automatically

About .jar Files

There are two types of .jar files in the context of TaCZ:

  1. .jar gun packs
  • Maxstuff, Daffa's Arsenal, Gucci & Vuitton Attachments, LesRaisins Append Pack, etc.
  1. .jar mod addons (which still can include gun packs)
  • TaCZ Tweaks, LesRaisins Tactical Equipments, TaCZ Durability, etc.

The upgrader can handle gun packs, but not mod addons; it's impossible to upgrade mods from 1.20.1 to 1.21.1 programatically

You need to put the .jar gun packs into the tacz folder, not the mods folder After that, everything should be handled automatically

Troubleshooting

  • Some gun packs may contain some dependencies to some of the mod addons (e.g. LesRaisins Tactical Equipments)
  • In that case you can't really do anything, since those addons doesn't exist on 1.21.1
  • Maybe you could find an older version of the pack that doesn't have the dependencies
