Hi guys,
I am making a UFO game and I have a UFO that steals a cow using an animated, rippling cone of light. Do you know how to make something like that, even in general terms?
There are a lot of ways you could do it but it depends on what your target platforms are going to be. One solution, that would work for pretty much all platforms, would be to take a hollow cone mesh and apply a translucent ripple pattern/texture to it. You would then just use a panner node and pan it along the vertical axis. If you wanted to get fancy, you could also modulate the refraction as well to add in some distortion.
