AE2 Lightning Tech: Simulation

By qiqi. An independent Minecraft 1.21.1 / NeoForge addon for AE2 Lightning Tech Reborn. Grow reusable simulation crystals with lightning, then use an ME network to produce minerals, crops, wood and mob loot.

Features

• Bind simulation crystals to resources and cultivate them into reusable production templates.
• Single-block chambers support up to 128 parallel operations, acceleration cards and automatic output.
• Multiblock chambers from 3x3x3 to 7x7x7 hold up to 49 crystals, with efficiency, fortune, overload and smelting upgrades.
• The modular Overload Thunder Coil provides lightning, mining tools and wrench functionality.
• Datapack recipes and documented Java APIs support modpack integration. Hold G over an item for its guide.

Required environment and mods

For 0.1.1-beta.1, install Minecraft 1.21.1, Java 21 and NeoForge 21.1.252 or later within 21.1.x. Install all four required mods at the following exact versions:

These versions match the released JAR dependency declarations. Original Lightning Tech and Reborn have different interfaces and cannot be substituted directly. CurseForge dependency relations link projects; they do not replace this exact version table.

Mekanism is optional, tested with 10.7.19.85. Mystical Agriculture 8.0.28 and Cucumber 8.0.16 were used for optional crop compatibility tests. They are not mandatory dependencies. No KubeJS dependency is required.

Install overload_sim-0.1.1-beta.1.jar on both client and server. Remove older addon JARs and back up worlds before upgrading. Source JARs and source ZIPs are developer downloads and do not go in mods/. Dependency binaries are not bundled.

Beta status

This version preserves the gameplay of 0.1b while preparing licensing, documentation and portable builds for public distribution. Generic resource matching does not promise compatibility with every mod. Entity equipment/NBT, special crop environments and block entities are not cloned. Long-running worlds, multiplayer and additional mod combinations still need testing. Native AE2 CPU on-demand crafting integration is not implemented.

Open source, licenses and attribution

Source code, scripts, documentation and original artwork are licensed under MIT, by qiqi and contributors. Adapted simulation crystal sprites, the crystal logo and seven coil module icons retain CC BY-NC-SA 3.0, based on artwork by AE2 Lightning Tech Reborn contributors. Crystal palettes and module symbols were modified. These assets require attribution, noncommercial use and the same license for adaptations; the MIT license does not replace their license.

This is an independent addon. No endorsement by upstream authors is implied. AE2, Lightning Tech Reborn, Thunderbolt Core Reborn and GuideME remain separate projects with their own licenses.
