How can I make a fluid simulation in game engine

Question

Is there a way to simulate a fluid in the game engine? It doesn't have to be 100% realistic (but not a cycling 2D animation). It just needs to be recognizable as water.

Optimally, there should be a way too make it not very computationally intensive, if it is by default.

No. You can't do fluid sim in BGE. Fluid simulation is a complicated process and won't run fast in real-time.

Only if it's built on a graphics card system, such as CUDA or OpenCL, it might be fast enough. But Blender's fluid system isn't. You might want to check into faking it with particles.

Thanks, I haven't thought about using particles instead. This might work – Luke_0 May 23 '13 at 02:38
No problem. ;-) Neat to see you on here also, @Luke. – Daniel May 23 '13 at 02:41
Could you bake the fluid simulation ahead of time for a static piece of scenery? – Nathan Osman May 23 '13 at 04:36
You probably could. But yeah, it would be static. – Daniel May 23 '13 at 12:17
I thought there were no particles in the game engine? – gandalf3 Jun 28 '13 at 01:22

Not an answer... But I thought I'd leave it here as a reference for any developer that might want to pick up on an old project:

Ian Johnson has done considerable work to get a working fluid solver (powered by OpenCL) in the Blender game engine. You can see a video of it here: http://enja.org/2011/12/01/rtps-fluid-and-rigid-body-interaction/

The feature never made its way into the official release.
