Question Shader not working (voronoi)

Hello i try to make some water for a game, i've followed several tutorials for it but i don't get the same results, my shader don't want to render the wobbles of my water and just show kind of white squares, see the picture below, thank you for any help and your time,

Antonin.

 

Are you create a TIME node?

But if you try create normal from voronoi, you will get very hard edges. I really wanna know how to smooth voronoi or something.

 

Yes, see the following screenshot :

 

So you test it in game actually? Tweak some parameters? Preview sometimes not show correct picture.
