AE2 Addon Lib Mod FAQ
10 questions players actually ask, answered.
Do I need to install this mod by itself or does it come with something else?
You only need to install AE2 Addon Lib if a modpack, addon, or another mod specifically requires it—it's a library mod that runs in the background. If you're playing a pack that uses AE2 addons, it will already be included.
What's the difference between this and Applied Energistics 2?
Applied Energistics 2 is the main mod with ME networks and storage systems. AE2 Addon Lib is a toolkit that lets other mods add custom machines and menus that work properly with AE2's systems—you need AE2 installed for this mod to do anything.
How do I register a new item or block with this mod?
Use the Registry Tools provided by the mod, which handle the setup process automatically for items, blocks, fluids, and materials without requiring manual configuration. The mod manages the registration behind the scenes so custom content integrates cleanly.
Can I add custom buttons and sliders to my machine's menu?
Yes—the Menu Widgets feature unlocks standard buttons from Applied Energistics 2 for custom use and includes a built-in slider styled to match the classic tech menu aesthetic. You can also add a full color picker that accepts hex codes.
How do I let players choose which direction a machine outputs to?
Use the directional machine output configuration feature, which gives players a menu interface to select exactly which direction (up, down, north, south, east, west) the machine exports items or fluids. This is built into the custom screen tools.
What's the fluid tank slot widget and when would I use it?
It's a special menu widget designed for custom machine interfaces that need to display or interact with fluids. Use it when your addon machine handles fluid input or output as part of its network integration.
Does this mod add anything visible to the player or is it all backend?
It's purely backend—the mod itself adds no blocks, items, or machines to the game. Everything it does is provide tools for other mods to create custom content that works smoothly with AE2.
Can I use this mod's tools to make machines that work with Applied Energistics 2 networks?
Yes, that's the main purpose—the mod is specifically designed to help custom machines integrate properly with AE2 item and fluid networks. The registry and menu tools ensure compatibility automatically.
Will this mod cause lag or performance issues?
No, AE2 Addon Lib runs quietly in the background and only handles registration and menu rendering—it has minimal performance impact on its own. Any lag would come from the addons that use it, not the library itself.
What happens if I remove this mod after using it in a world?
Any custom machines or items added by mods that depend on AE2 Addon Lib will likely break or disappear from your world. Only remove it if you're also removing the addons that require it.
