About this Mod

Impactor

A developer API meant to streamline work in a common environment, and support any sort of Minecraft environment, modded or vanilla.
Additionally, Impactor attempts to maintain commonality amongst its codebase across Minecraft versions.

Impactor's primary objective is to simplify the work other developers are required to complete, while also
allowing them to better support multiple platforms. Examples include:

  • ItemStack Creation
  • Players and Entities
  • Scoreboards
  • Economy

Provided Feature Set

While Impactor is a developer API at heart, it also provides a set of provided features server owners can
immediately leverage just with installing this API.

Economy

A built-in service for the Economy API is provided by default, allowing you to establish a ready to go
economy system.

The provided system supports multiple types of currencies and provides basic commands capable of interacting
with the system. We also provide a /baltop command for those interested parties.

Should you be using another EconomyService, Impactor's API allows the replacement of our default service
with a service which can mirror any API calls to the service you yourself are using. While this will
require code, Impactor can be leveraged to feed information to other plugins while not requiring plugins
to outright support multiple different economy systems.

As of 5.3.5, Impactor supports the following platforms:

  • Fabric
  • Forge

Using Impactor in your Projects

Impactor does its best to provide API access in a manner that allows you to only pull in what you need. With this
in mind, here's an example of pulling in the current economy API:

repositories {
    maven("https://maven.impactdev.net/repository/development")
}

dependencies {
    implementation("net.impactdev.impactor.api:economy:5.3.5")

Frequently Asked Questions

Impactor server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is Impactor compatible with fabric and forge and neoforge?

Impactor officially supports fabric, forge, neoforge for Minecraft 1.21.1, 1.20.1, 1.19.2. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Impactor – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Impactor consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
