What if we had a ratio, say, 3-1 buoyancy to weight retro, that if you had, say, five floating blocks for one regular block, the thing would float in air. Then, you could make blimps! Hot air balloons! Zeppelins!
You would go up, and the higher you go up, the faster you'd go up, because the air is thinner and lighter. How would you get down, you ask? That's for everyone to figure out for themselves.
Oh! And stea, engines. Not steam locomotives, but engines, that could power props and wheels, for us steampunk people.
Finally, toggleable cylinders on a car engine. So the more cylinders you have, the more horsepower you could have, but you couldn't have less than two or more than twelve. Thoughts?
@WNP78 I can't
@palp yes but when the RigidBody turns out to have overall negative mass, bad things happen. Have you tried it?
@WNP78 negative mass is possible
Just with XMLed fuel tanks
@WNP78 or just make them generate lift even when they are stationary.
@EternalDarkness well, unity can't handle negative mass because negative mass is impossible. I don't think it natively calculates displacement and density etc. I think what would be in order is a fuselage that can be 'filled with helium'. It would then generate an upwards force, and explode a lot easier.
Good idea
This get down you could have ballast tanks or vent hydrogen/helium or have a wav to reduce upward force
@WNP78 I don't know much about programming. Lift of any kind, including buoyancy, really is an upward force. This is only one of many things I would like to see in some future update.
@EternalDarkness well, it's hard, since unity can't handle negative weight, it would need a force pushing it up. Since the way the game merges and creates RigidBodies, creating the force in the right place could be hard. Although, I haven't looked and there might be a function to do just that.
You got the concept wrong. The higher the ligter-than-air aircraft goes, thinner air it encounters, thus being less buoyant and climbing slower. Besides that, ligter-than-air blocks are great idea. Actually, it's so great that it has been proposed around fifty times already.
