Liquid Model (.liquid)

Overview​

note

Not to be confused by Liquid Physics, this article its for the rather unused Model Liquid

Model Liquids are a rather special mode, they don't use a model mesh per say, but uses a .liquid file in the liquid/ folder under the game folder.

Liquid models are unique in the sense that they are create in runtime under the contents of the .liquid file:

seed 1337420

size_x 256
size_y 256
verts_x 16
verts_y 16
liquid_type 2
density 0.97
drop_height 4
drop_radius 4
drop_delay 1.0
update_rate 30
shader textures/base_floor/conc_panel02

Would create something like this:

testModel models/water2.liquid

Breakdown​

A .liquid file consist of the next :

  • size_x/size_y: In Units, defines the size of the liquid plane.
  • verts_x: Must be at least two per axis.
  • verts_y: scale_y = size_y / ( verts_y - 1 )
  • liquid_type: defines the deform; must be 1, 2 or 3.
  • density: The actual "density" of a liquid, but rather a percentage of time of animation in which it deforms?
  • drop_height:
  • drop_radius:
  • drop_delay: In Seconds, controls how many second it takes for the liquid to rest.
  • update_rate: Dictates how fast the animation is. in hz [60 >= val > 0].
  • shader: The texture to be use for this liquid.
