/*

===============================================================================
|
|
|
|
Physics object for a liquid. This class contains physics properties for a
|
|
given liquid. Note: Liquid does not necessarily imply water.
|
|
|
|
This class does very little functionally as it relies on the other physics
|
|
classes to do the bouoyancy calculations. It simply holds information and
|
|
allows the other object to deal with that information however they please.
|
|
|
|
As a side note, the difference between minSplashVelocity and
|
|
minWaveVelocity is that min splash is the minimum amount of velocity
|
|
before the liquid spawns a splash particle. minWaveVelocity is to generate
|
|
a wave on the surface, not a splash. It should be lower than min splash
|
|
velocity. It's the reason some things won't splash but will still cause
|
|
ripples in the water (especially when surfacing)
