ModPacker - 1.6.2
Unofficial Tool for installing and creating mods for Wargroove. This Tool is required for installing mods in .hmd format.
The download comes with one simple Mod which removes the intro video for testing the installation process.

In Version 1.6.2 it supports modding/replacement of Sprites, Music, SFX, LUA scripts, Config files as well as spritesheet/animation definitions.
(For those wondering this allows you to do more than just visual stuff: Look at the example video I uploaded and see yourself)



Notes for updating the game:
  1. Make sure the game is in vanilla and updated state (verify integrety in Steam).
  2. Then go to your wargroove installation. (should be [steam]/SteamApps/common/Wargroove/assets)
  3. In this directory delete the "mod_bckp" directory and restart the Tool.


Requirements:
  • Java >=11
  • (If you do not want a permanent Java installation, an optional portable download including a runtime is provided)


Usage (Installing Mods):
  1. Extract the zip file.
  2. Run the included .jar
  3. The Tool will look for a Steam installation of Wargroove. When that cann't be found you will be asked to manually select the "Wargroove" directory.
  4. Click Use/Apply Mods. You will be presented with a window like this:
  5. You can add, remove and reorder mods using the Buttons on the right. (In .hmd Format of in a .zip containing a single .hmd)
  6. Clicking apply will install any mods you added. (Note: This operation will take 1-3 minutes mostly depending on your harddrive speed)
  7. (Clicking apply with no mods in the list will revert the game to vanilla state)
  8. If everything worked correctly you will now see additional text on the main menu of the game indicating how many mods were installed.

Usage (Developing Mods):
  1. Run the Tool like above, but select Develop Mod
  2. Press Unpack Game Data (Note: This operation will take 1-3 minutes mostly depending on your harddrive speed)
  3. The extracted Game Data can now be found in the /data/ directory
  4. Since Version 1.5.0 using the patching system is recommended whenever possible (please read /docs/patches.txt)
    (Only if needed: Modify these files as required)
  5. To test your current modifications, press "Apply changes to game" and run the game
  6. With the modifications complete press Pack Mod
  7. Fill in the Mod Name/Description/Authors
  8. The Tool will now pack a .hmd in the /mods/ directory which only stores the modifications you made  (Note: This operation will take 1-3 minutes mostly depending on your harddrive speed)

Notes for modding:
  • The .pro files mainly describe properties of how the file is stored in the .dat and contain no relevant information for most mods. Change them only if you "know what you are doing" as that can quickly result in the game crashing.
  • Config, SpriteSheet Definition and Animation Definition files are converted from binary to a more editable JSON format
  • Version 1.2.2 and up feature new tools for swapping indexed/paletted images to something more managable. Just "PaletteSwap" an image, edit it and the "UnPaletteSwap" it again.
  • Version 1.3.2 and up feature a tool for extracting animation frames/single sprites from spritesheets (see the readme changelog for an explanation)
  • Please run "Unpack Game Data" again after updating the tool, as old unpacked data can become incompatible with certain changes
  • Please read the included documentation in /docs/
