Water effect "on android" for a 2D game. Where to start?

Question

I wanna to add some water effects in my android 2D game to give the impression that objects are under water and the water becomes higher and higher. Is there a way to do this programmatically. May be someone can give me please some code suggestions or can say where can I find something to get started. I like to do things programmatically. One time I saw a fire effect artificial done with code. Is the same possible in the water case ?

Answer 1

You're going to have write a gl shader for the water effect.

steps:

• render scene to render target (texture)
• apply shader to render target

There are many different ways to write water type shaders in 2d. Search around for the technique that best suites your needs.

Caveat: Shader only work on devices with programable pipelines (devices that support OpenGL ES 2.0+
