Click on the Strechted hinge, go to axle and apply brake to it. In order to move.

Other than that, this is fast.

Nope.avi

Please make it run on something other than an axle motor please. That isn't even considered an engine.

Anyone teach me.

I'm pretty sure Vaidas has a spawn engine tutorial scene if you want to look at it.

Phun User who told you to critize others scenes?

Nitrocide who told you we can't?
First of all you had to press the Right key instead of going to the menu and adding a brake, it was already done xd, also this is fast because it's simply an axle (you can do that in less than a minute)
Second we have a right to say whatever we think about someone's scene, especially if we're gonna give feedback about the scene.
And you fail on the same part than him: your scenes are too simple, no engine, no gearboxes, no track... that's not a good scene by any standards! At least this guy is trying to change his quality...

Now some help:
-use density 50 or more for every part of the engine: this gives much better collisions. On the flywheel you might need more, so that the output is more constant

-always use 120 Hz or 200 Hz for your scenes, preferrably 120 Hz. you can change that going to Settings (the gear on the upper left corner) -> Simulation, and changing the slider. this gives even better collisions

-Use more realistic scales, that engine is 4 meters long, keep it less than 50 cm long

When you're done adjust the spring slowly until the engine blows up, then undo and adjust it below that line, and you'll have a decent engine

p.s, I saw your comment on the previous scene. you don't need scripting for a spring engine lol
