I notice that in a lot of games water is simulated with moving (square) textures. They use transparency with a water texture. I can handle the transparency and the texture, but I’m not sure of a way to simulate the movement and not have the square texture protrude from what it’s moving in.
For instance, if the following is a birds eyes view of square swimming pool how can I animate my textures moving whithin the boundaries of the pool? Thanks so much.
