This asset provides you with realistic fluid simulation and visualization for your games. It includes a guide, a well-commented example, and documentation for each script making it easy to implement it into your game. The physics and visualization are done with shaders, making the fluid simulation very fast. The asset is highly customizable, letting you tweak the fluids extensively. It can be used to simulate fire, smoke, gas, dye, dust, wind, water droplets, cloud formation, and much more. Development and testing has only been done with the windows VM target and the windows YYC target, you might run into problems if you use this asset with other targets.


  • Can simulate fire, smoke, gas, dye, dust, wind, water droplets, cloud formation, and much more.
  • Using new mathematics from 2014 making fluid simulation faster than ever before.
  • Instances can be pushed around by the velocity field of the simulation.
  • Custom collision masks from sprites and surfaces.
  • Can be tweaked to imitate versions of explosions and tornadoes.
  • 9 different example implementations of fluids.
  • Can be used in small, large and infinite game worlds.
  • Everything is highly customizable, built on top of a fundamental fluid simulation.
  • Custom shaders.
  • Choose between two shader languages, HLSL 9 and GLSL ES.
  • A guide for implementation.
  • Commented and organized code.
  • Fast and optimized, made with efficiency in mind.
  • Custom time step.
  • Customizable acceleration equation.
  • Optional dissipation of fluid velocity and material.
  • All in GML, HLSL 9, and GLSL ES.

Note: You might run into some shader errors after importing the asset due to a GameMaker marketplace import bug, but this can easily be solved by following the instructions in the "readme" script provided with the asset.
