I am not sure how to make a texture of water make waves and stuff. I know how to do it in Render, but not BGE (Blender Game Engine). Any help would be appreciated.

    $\begingroup$ How about an animated texture? If you rendered out the waves in Blender Internal, then loaded them into the BGE, you would have animated water. $\endgroup$ – CharlesL Jul 1 '13 at 23:13

  • $\begingroup$ @BlenderLover It's not quite moving water, exactly, but you might find this interesting.. Water Shader and pre-made BGE shaders $\endgroup$ – gandalf3 Jul 17 '13 at 2:20
  • $\begingroup$ There is also deformation scripts I use that actually make real and animated waves in the game engine, I'll post back here with a proper .blend file within the week. $\endgroup$ – Shane Johnson Jun 7 '14 at 18:20

The only way that works well and looks great in the BGE, is creating an animated water texture.

Having real geometry to create displaced waves in the game engine would look cool, but it is very memory intensive and would cause your game to lag.

To create an animated texture for the water, there are quite a few steps. Here is a video that describes the technique used to create the water used in the Blender Game "Yo! Frankie".
