Well, the thing with fog mist and steam is, those are mixtures of water
as a liquid and air as a gas, not uniform quantities of some element element
(or even molecules).
Some more examples:
whipping action
solid cream(l) + air(g) -----------------> whipped cream(mixture)
stirring action
water(l) + sugar(s) -----------------> sugar water(mixture)
combustion
wood(s) + air(g) -----------------> fire + smoke(mixture)
cornstarch(s) + water(l) -----------------> "goop" (sometimes solid,
sometimes liquid)
Try making some "goop" at home. Get some cornstarch and mix in some water,
when you squeeze it it feels solid. If you leave it alone, it turns to a
runny liquid. Neat stuff. 8')
Anyway, the way that I'd do it would be to define some base type of matter
that can be some lump that is recognizable as a unit and has three properties:
quantity of mass, material, and form.
The material will define the density. From the material and the mass, you
can find the weight. Add in the form, and you can find the shape and volume.
quantity of mass is a number that tells you how much of something you have
(grams, kilograms, whatever)
form is
fluid(x) liquids and mixtures in liquid form (may have a viscosity x to
it as well. Viscosity is "resistance to flow" - maple syrup
would have high viscosity, while water would have low
viscosity.)
gas A gaseous state, like air or helium
granular(x) solid, with X corresponding to the number of times the thing
has been broken into smaller pieces. So X=0 would be a single
gold brick, X=1 maybe big gold nuggets, X=2 for gold gravel
X=3 for gold sand, X=4 for gold dust... etc.
plasma Certainly some more research is involved if you want to add
plasma to your game. But that would be very cool. 8')
material is what it's made of. Could be a mixture, complex structure, or pure
molecular/elemental type. Lots of room for development here, depending on how
involved you want to get. (are animals and plants the same or different
subtypes of "organic", etc...) There are mixtures, alloys, all kinds of neat
stuff. Go to your college book store and sit down with a Chemistry 101 book
and thumb through it for a while for ideas. There is some neat stuff in there.
You could also add a propery temperature. And when an object's temperature
changes, you can see if it changes state based on the material.
Another thing to add for support would be a table of reactions, to see what
happens when various elements are put together. To add some sophistication
(and difficulty in testing!), you could make some rules about the way elements
react, and do reactions that way.
Good luck! Sounds very promising!
