The real AIR COMPOSITION (nearly) is:
78 % Nitrogen, 20 % Oxygen, 1% Water Vapor, 1% Carbon Dioxide.
I did the same mixture and replace the Nitrogen by Hydrogen ( because Powder Toy don´t have Nitrogen).
How to make a "similar" to real air in Powder Toy ?
I guess you will have to count how many pixels are there in this game and make it equals to 100% and then you will have to do some maths to figure out how many pixels should your simulation contain from each element.
Yeah...
So this got locked by the mods, and you've just created a new topic, which is exactly the same. You also seem to have solved your own problem in your post. What are you asking?
thanks all for information, and sorry for the duplicate thread....
