ItemDefinition

This is a special JSON object that is used by CreateEffect and ValueChanger to target specific items from other modpacks.

• When used with CreateEffect, it allows you to spawn items that originate from other modpacks.
• When used with ValueChanger, you can create dynamic values based upon the number of these specific items in your backpack.

Note: In order to target items from another modpack, the player must have both your modpack and the other (target) modpack installed at the same time.

The ItemDefinition object should consist of a single key:value pair, where the field name should match the internal_name of the target modpack which contains the item, and the value should match the name of the target item within that modpack.

Field Name	Optional?	Description	Data Type
<any .*>		Item name within the target modpack	string

Example usage:

The following examples are based around the "Strength Cleaver" from the "Farlands Dwelling" modpack (which has the internal_name of "Farlands"):

Example with CreateEffectExample with ValueChanger

This example shows how you might use a CreateEffect to spawn a Farlands Dwelling "Strength Cleaver".

    "create_effects": [
        {
            "trigger": "onUse",
            "create_items": [
                {
                    "Farlands": "Strength Cleaver"
                }
            ],
            "create_areas": [
                "board"
            ]
        }
    ]

This example shows how you might use a CombatEffect to add a Block amount equal to 5 times the number of "Strength Cleaver" in your backpack.

    "combat_effects": [
        {
            "trigger": "onUse",
            "type": "Block",
            "target": "player",
            "value": {
                "replace_with": "numOfItems",
                "multiplier": 5,
                "check_items": [
                    {
                        "Farlands": "Strength Cleaver"
                    }
                ]
            }
        }
    ]

Finding a Modpack's internal_name

The internal_name of a modpack will often differ from its published name. Here's a quick and easy way to identify the internal_name of a modpack without having access to its source files:

1. Subscribe to the modpack and install it (by checking the corresponding box in the Ctrl+M menu)
2. During a run, open the debug menu (Ctrl+D) and press "Show Logs"
3. Search the logs for a line such as: Debug Farlands - Strength Cleaver: Loading item Strength Cleaver
4. This log has revealed that the modpack containing the "Strength Cleaver" has an internal_name of "Farlands".
