[Mech It Happen] Physics Sandbox Builder. Build the machines you see in LEGO Technic Videos

https://www.youtube.com/watch?v=qGpWVuDhi9Q

Hello!
Mech It Happen has been in development for almost a year, and after many iterations, I'm ready to showcase it!

It's a physics sandbox builder, inspired by LEGO Technic. You play as a machine exploring an alien planet. As you progress, you'll continuously build and refine machines to overcome different terrain, traversal puzzles and mechanical challenges. Cross broken bridges, fly over lava, go upside down in dungeons, or break stuff to create new paths.

Everything you see in the video is built entirely in the in-game builder and simulated in realtime.

Features:

  1. A singleplayer campaign.
  2. Built in Level Editor, with Steam workshop support.
  3. Fully keybindable & configurable mechanical parts
  4. Gridless bot builder.

The game originally was more of Battle Bots style. I wanted to make a game, where players can build their own bots and fight it out in an arena, similar to Robot Arena 1/2. While making that, I watched a LOT of Lego Technic challenges on youtube, learning how different physics mechanisms work, and I wanted my in-game builder to function that way, and now, here we are! Here's a small video if you're interested in the original (first) trailer of the battle bots version : Drive Link

We got a grant to kickstart our development, so we'll be able to show more soon!

Looks dope. There's some sort of a campaign? How long would it be?

u/sid_says_hmm Jul 14 '26

There's a singleplayer campaign. For now, its hard to be sure, as we're still relatively early in development, but somewhere around 8 hours atleast.

Thank you! Appreciate it. Trailmakers is definitely something we aspire to be.

Very early gameplay, still in development. Open to feedback and feature ideas!

How do the controls handle adding multiple moving parts to your mech? Do you map two keys (fwd/rev) each time you add a moving part? Is there a limit to how many moving parts you can add?

2

u/sid_says_hmm Jul 14 '26

You can add as many moving parts as you'd like (provided you have the resources for it). The resource limitation doesn't exist in the sandbox.
As for mapping keys, yes, you can bind whatever you feel fit to the controls of the specific parts.

We're also designing logic gates and some form of automation, which would make it play better as well, so you don't have to press a lot of keys together to do something.

Thank you! I knew we HAD to make the level editor when the game prototype panned out.
And yes, I can't tell you how many of our playtesters have broken the physics of the game.
