Gaseous Physics in Powder Toy

Not sure if this has been mentioned before, but if it has I would like to strech its importance. When you go to game settings and switch air pressure off and set the world to "radial gravity" gas is not attracted to the center, instead it remains where it was (with a little bit of diffusion depending on the type of gas), in real physics if there was a gravity well it would attract liquids, solids and gases, I understant it would be too difficult to implement solids as moving things but having gases react to gravity would be nice.

Exactly. Some gases are 'heavier' than others. All the other 'lighter' gases just continue to diffuse. If you were to place a gpmp or a dmnd ringed bhol, and place gases around them, they stay on the surface instead of diffusing outward.

Actually I just tested the game again to verify this information and again it turns out to be incorrect, Water Vapor or WRTV floats away from the center of gravity on the screen, it is trying to replicate air pressure even when it is off, meaning that its actions are dictacted by a code telling it to "move away from gravity" instead of calculating an actual mass value which should determine where it goes. CO2 does floats tward the center of gravity because it is coded to go nearer as it stated CO2 is a "heavy gas and floats down". to further conclude my argument PLSM or plasma flame goes in the opposite direction of gravity even without air pressure on.

a lot of base elements are following false physics laws to look like they look irl, so that you have an approximate mapping between the real world and the simulation. TPT is not a physics simulator
