The Tweak Units modoption can be used to modify many unit and weapon parameters. It can be used for rapidly testing balance changes or just for making a quick game mode. It has limitations and should not be used for large mod projects, see Mod Creation to get started on full modding.

Workflow

The Tweak Units modoption overwrites unit paramers (called unitDefs) as they are loaded. The modoption requires a base64 encoded lua array of differences. Here is how to use it.

  • Make a lua table in an empty file.
  • For each unit you wish to modify, add an empty table indexed by the internal name of the unit to your table.
  • Search for the units you wish to modify in the Zero-K repository.
  • Copy the parameters you wish to modify into the table, maintaining the structure of the unitDef table.
  • Base 64 encode your table.
  • Put the base 64 encoding of your table into the Tweak Units modoption.
  • Start the game.
  • Check infolog.txt in your install directory and fix your syntax errors.

Check out the unit def and weapon def pages on the SpringRTS wiki for definitions of many of the parameters. Search the internet for tutorials on lua tables.

Simple Example

In this example we make Glaive faster and healthier.

Start with an empty lua table.

{
}

A search through the unitdef repository reveals that Glaive is known as cloakraid internally. This is the file. Add an empty table with key 'cloakraid'.

{
    cloakraid = {},
}

The SpringRTS wiki page on unitdefs says that a unit's health is 'maxDamage' and its speed is 'maxVelocity'. The Glaive file shows us the current value of these parameters, as well as their position in the structure of a unitdef. We can change these values like so:

{
    cloakraid = {
        maxDamage = 500,
        maxVelocity = 8,
    },
}

Copy this text into a [base 64 encoder http://www.example.com] and click encode. Here is the resulting encoding.

Set the Tweak Units modoption to your encoding and start the game. Your infolog should indicate that the modoption loaded successfully.

[f=-000001] Loading UnitDefs_posts
[f=-000001] Loading tweakunits modoption
[f=-000001] Loading tweakunits for cloakraid
[f=-000001] Loading FeatureDefs_posts
[f=-000001] Loading WeaponDefs_posts
[f=-000001] Loading ArmorDefs_posts

Advanced Example

In this example we will change Bandit's damage and range, and add it to the Glaive changes.

As in the simple example, we find the Bandit's file and see that it called shieldraid. To change Bandit and Glaive at the same time we add a new subtable to the table from the previous example.

{
    cloakraid = {
        maxDamage = 500,
        maxVelocity = 8,
    },
    shieldraid = {},
}

Weapon parameters can be found in the SpringRTS page on weapon defs, and Zero-K stores them as a subtable within unitdefs. The range parameter is inside 'LASER' (the internal name of the Bandit's weapon), which is inside the weaponDefs table of Bandit. Weapon damage is further nested inside the damage sub-table of the weapondef.

{
    cloakraid = {
        maxDamage = 500,
        maxVelocity = 8,
    },
    shieldraid = {
        weaponDefs = {
            LASER = {
                range = 600,
                damage = {
                    default = 50,
                },
            },
        },
    },
}

As before, we now take this text, [base 64 encode http://www.example.com] it, and copy it into Tweak Units. Encodings can be shortened by removing whitespace prior to encoding.
