Mod Loaded (Meta Condition Type)

Checks whether another mod is installed, optionally at a given version. It ignores its context entirely, so the same type is available wherever a condition is — entity, bi-entity, item, block, damage, fluid and biome — and in a power’s load_condition.

Type ID: apoli:mod_loaded

Fields#

Field	Type	Default	Description
mod	String	optional	A mod id that must be installed.
mods	list of String	[]	Mod ids that must all be installed.
version	String	optional	If set, every named mod’s version must also satisfy comparison against this.
comparison	Comparison	>=	How each mod’s version is compared to version.

At least one of mod / mods must be given; with neither, the condition is never fulfilled. Give both and every id in both has to match.

Versions are compared number-group by number-group, so 1.9 is older than 1.10, and a release is newer than its own pre-releases (4.2.0 beats 4.2.0-beta.1). Anything after a + is build metadata and is ignored, so 4.7.6+Fabric compares as 4.7.6.

A mod’s presence never changes while the game runs, so this is resolved once, when the JSON is read. Testing it per tick costs nothing.

Examples#

"condition": {
    "type": "apoli:mod_loaded",
    "mod": "icarus"
}

Fulfilled while Icarus is installed.

"condition": {
    "type": "apoli:mod_loaded",
    "mods": ["pehkui", "trinkets"],
    "inverted": true
}

Fulfilled unless both Pehkui and Trinkets are installed.

"load_condition": {
    "type": "apoli:mod_loaded",
    "mod": "icarus",
    "version": "4.0.0"
}

As a load_condition on a power: the power is only read at all when Icarus 4.0.0 or newer is installed. That is the only way to use a power type that does not exist without its mod — apoli:wings is registered only when Icarus is, so a plain condition cannot save a power that names it.
