Water Ripple

In the 20,000 Leagues Under the Sea course in Walkabout Mini Golf, the kraken can be seen around the ship. On this hole, one of its tentacles is wiggling in the water, so I added a ripple wave effect emanating from the center of the tentacle. For the final shader, we hard-baked the location values for the ripple origin, but in the setup, this was done with a global value attached to an empty game object we could move around the scene to grab the location values. This could also be turned into a dynamic shader using the same setup method exposed to the player by adding an event trigger and falloff logic.
