Algodoo

i know the human the are inside on the vehicle

Its heavy weapons guy from team fortress 2

Very very very good scene. 9/10 is near to perfect
I really enjoy playing and dig into scripts/mechs!
No such cool games for a few months...

Few advices:
Since you using algodoo - use lasers and onLaserHit event instead of frequently collided-circles.
Use inertiaMultipler (new from 1.7.1) and airFricionMultipler property instead of that stretch-hinge stabilizers.
Negative fuel is impossible - you must check it on decrease in scripts.
Make fuel indicator parts zero friction and restitution to avoid bouncing.

And couple of suggestions:
Make fuel flow more on acceleration and less while standing (you can do it with lasers).
I'd like to keep ability to move claw even if I have no fuel.
Wheel can be more realistic with simple shadow texture.

Thanks Kilinich. I used collides pecause of Phun users. And I noticed negatife fuell posibility after I have uploaded the scene. And fuel really flow more when moving.

I think I re upload the scene, and fix some errors.

It's not work in phun anyway.
density=0 crash phun
gif textures not supported
springs reset
low perfomance

Forget it

Ok thanks.
