A lua setup I’ve been working on. It does a few things:
Sets up turn switch so that different positions can trigger different functions (in this case cycle between flipmaps)
Uses a combination of flipmaps and room water property changes to flood the levels sequentially without excess water textures in between
Opens and closes lower doors at appropriate times
Moves waterfall mist to stay on the surface of the water
Adjusts sink strength to calm the water when at highest level
Detects kayak in the room and moves it up/down along with the water level (otherwise kayak floats or is submerged)
All in all, this allows a turn switch to control the water level, and allows the kayak to move up and down the water levels to reach new areas.
Tutorial and final lua code to come.
