Truss Mod: Unleash Moving Contraptions in Minecraft
Minecraft has always been about building, but what if your creations could actually move? The Truss Mod brings that dream to life by introducing motors and frames that can shift entire structures across your world. Inspired by the legendary Red Power 2 by Eloraam, this mod lets you construct elevators, sliding doors, rotating platforms, and much more—all while blocks continue to function and render smoothly during motion. Whether you are a redstone engineer or a casual builder, the Truss Mod opens up a new dimension of mechanical creativity.
What Is the Truss Mod?
The Truss Mod is a technical Minecraft add-on that adds block-moving mechanics directly into the game. At its core, you have motors that provide directional force and frames that connect together to form large, cohesive structures. When activated, these frames slide, push, or rotate, carrying every block attached to them—including tile entities like chests, furnaces, and even machines from other mods. The result is a seamless moving contraption that feels like a natural extension of vanilla redstone, but with far more power and flexibility.
Key Features
- Motors and Frames: Motors generate movement, while frames link blocks into a single moving unit. All blocks render and tick during transit, so machines keep working as they slide.
- TileEntity Support: Chests, furnaces, and complex machines from IndustrialCraft 2, BuildCraft, or Thermal Expansion can be moved without breaking.
- Power Compatibility: The mod accepts energy from IC2, BuildCraft, and Thermal Expansion systems, making it easy to integrate into existing setups.
- Microblocks & ForgeMultipart: Both Immibis's Microblocks and ForgeMultipart are fully supported. Covers and panels can mask frame sides, allowing for sleek, hidden mechanisms.
- Multiblock Movement: With proper configuration, entire multiblock structures like Railcraft tanks or Forestry alvearies can be shifted as a single unit.
- Per-Block Handling: A configurable handler system lets you fine-tune how individual blocks or entire mods behave when moved, preventing crashes and desynchronization.
Installation Guide
Getting the Truss Mod running depends on your Minecraft version. For the older 1.5.2 era, you needed to extract TrussCore-*.jar into the coremods folder and TrussMod-*.jar into the mods folder. Starting from version 1.6.x and later, the process simplified: simply copy TrussMod-*.jar into your mods folder and you are ready to go. If you are using a modern launcher like foxygame.net, the whole experience becomes even smoother—this convenient, flexible launcher lets you download mods right from the menu, so you can skip the manual file hunting and add the Truss Mod with just a few clicks. No matter which method you choose, always double-check that you have the correct version for your Minecraft client.
Using Motors and Frames
Once installed, the first step is crafting a motor and some frames. Motors are the heart of any moving machine, and controlling their direction is intuitive. Shift-right-click with an empty hand to cycle the position of the red action side—this determines where the force is applied. A regular right-click with an empty hand changes the direction that red side faces, letting you push, pull, or rotate structures exactly how you want. Frames automatically stick to adjacent blocks, but there is a clever twist when microblocks are involved.
Microblock Interactions
Any cover-thick microblock will prevent frames from sticking to that side, effectively masking the frame and giving you a clean appearance. If you place covers or panels on a frame side, that side becomes solid visually and functionally, allowing you to hide the mechanics behind a seamless facade. This makes the Truss Mod perfect for hidden doors, retractable bridges, or moving platforms that blend into your build.
Moving Multiblock Structures
One of the most powerful aspects of the Truss Mod is its ability to relocate entire multiblocks—if you configure it correctly. By editing the TrussMod.cfg file, you can add specific block sets that the mod should treat as a single movable unit. For example, adding S:alveary=1382 or S:railcraft_tank="452:0,452:1,452:2" tells the mod to move all those blocks together without breaking the structure. In newer versions, you use block names instead of IDs. This feature is a game-changer for factory builders who want to rearrange their production lines without dismantling everything.
Known Issues and Compatibility
While the Truss Mod works with most mods from the FTB 1.5 beta pack, a few quirks remain. Items moving through BuildCraft pipes may not update their rendering state after the pipe itself is moved—though the items still travel correctly, you might see visual oddities. Some mods with default-hard handlers can cause tiny time desynchronizations, leading to brief stuttering. Most notably, Thermal Expansion blocks are known to crash or disappear when moved, so exercise caution with those. The mod includes per-block and per-mod handler configurations to mitigate these problems, so checking the config file before building large contraptions is always wise.
Conclusion
The Truss Mod revives the spirit of Red Power 2 and pushes Minecraft’s engineering possibilities further than ever. With motors that respect tile entities, frames that integrate with microblocks, and the ability to shift entire multiblocks, it is a must-have for any technical player. The learning curve is gentle, and the payoff is a world where your builds are no longer static—they come alive with motion. Just remember to tweak the configs for your favorite mods, keep an eye on compatibility, and let your imagination engineer the next great moving masterpiece.
