Build a bridge lets you auto-generate bridges in Minecraft 1.12.2 with a single command. Choose from built-in presets (railroad, plain, stone brick, wooden) or define your own custom template — complete with automatic support beams, torch lighting on railroad pillars, and smart headroom clearing so you can walk across immediately.

📦 Installation
- Install Forge for Minecraft 1.12.2.
- Place the
buildabridge.jarfile into your.minecraft/modsfolder. - The mod is required on both client and server — install it on both sides for multiplayer.
No additional dependencies are needed.
✨ Features
/bridge <length> <preset> [x y z]— Build a bridge instantly in your viewing direction./bridge custom <length> <roadBlock> <beamBlock> [x y z]— Use any blocks you want for road and support beams.- Four built-in presets —
railroad(cobblestone + rails),plain(cobblestone),stone_brick, andwooden(oak planks). - Automatic support beams — Placed every 25–30 blocks; beams descend through air, water, lava, and glass until they hit solid ground, then dig 5 blocks deeper.
- Torch platforms on railroad bridges — A cobblestone platform with a torch lights every support pillar.
- Headroom clearing — At least 2 air blocks are cleared above the bridge so you can walk without hitting your head.
- Smart starting position — Without coordinates, the bridge starts one block below your feet to avoid building inside you.
- Direction detection — Bridge extends north, south, east, or west based on your yaw.
- Input validation — Length limited to 1–10000; invalid presets show a helpful list of available options; block names for custom templates accept
minecraft:prefix or just the block name.

❓ FAQ
Does this need to be installed on the server?
Yes. The /bridge command modifies world blocks, so both the client and the server must have the mod. In single-player it’s fine because the integrated server loads it.
Can I use blocks from other mods for custom bridges?
Yes, as long as you specify the full block name (e.g., modid:blockname). The validation will catch unknown blocks.
Is it safe to use on a survival server?
Absolutely. All block placements respect existing terrain rules, and the command can be restricted via permissions (OP-only by default).
I found a bug — where do I report it?
File an issue on the issue tracker. Include your Minecraft version, Forge version, and a log if available.
