How to make a sine scrolly, a scrolling message that waves up and down as it moves across. A sine wave is applied to the Y position of the characters of the message as it moves across the X axis. The wave is also shifted across the X-axis as the message moves.
In this video, there is a preview of how the sine scrolly looks (this is recorded after the rest of the video). Then, step by step, the sine scrolly is built in Java. Follow along and build you own!
This was a popular technique used in the 90s 16-bit demo scene.
