Woohoo FISHIES! And RAIN!! MOVING WATER!!
These are kept simple because they’re so small. The models were made in Blender and have no animation. The movement is done in Unity by script using “Random.insideUnitSphere”. Each fish uses this function to swim around random points in a sphere of a pre-determined size.
I may add waggling tails at some point… You can’t have fishies without waggling tails…
This is done via a really neat tutorial that teaches you how to take advantage of 2 particle systems working together—one to create the rain itself, and one to simulate the “splashes.” I highly recommend it for a nice raining-and-splashing effect.
This is actually the same gradient color shader that is used on all objects in the game scene. The only difference is that this one allows for transparency. The “waves” or “white caps” were drawn in GIMP on a png texture, which was then added to this transparent, gradient color shader.
We would love to hear your thoughts!
Here’s a bonus screenshot in case anybody wants to use it as phone wallpaper:
