If I make a wave with wave modifier then keyframe it making an animation, can I play it in the game engine with Logic bricks, or do I need a script. If there is an example to see that would be great.

Would need such a thing too, hopefully there will be some answers…
a quick test showed this doesnt work.
Is there a script for what I want?
digiman
thats a bit beyond me. if someone did figure this out, it would likely be very inefficient.
I believe shape keys might work, untested though
Let me tell you what I need and maybe there is a way to do it. I making an underwater scene and I wanted to see the water surface with the ocean bobbing up and down. Isn’t there a way to play animations in the game engine?
digiman
To my knowledge most modifiers simply get discarded when the BGE starts.
So you’d have to do this with code, but it’s not too difficult, there are several solutions on the forums ; )
I have looked that’s why I am asking. Let me know if there are any example blends.
digiman
try this maybe? it’s 3 years old though… so the code may be outdated 
I personally use WasserTextur to make animated normal maps for the bge, there is no physical displacement, but it gives the effect of moving/flowing water… but the software is only in german, and can be annoying to get the hang of using it… heres the link anyway (Website translated from german) - https://translate.google.co.uk/translate?hl=en&sl=de&u=http://www.blitzforum.de/showcase/%3Fproject%3D344&prev=search
I used to use normal maps with 2.49b but looking for something that behaves like an ocean wave modifier. Thanks for the suggestions
