Whilst working on my Xojo game, I had the need to display a moving star field on a window (similar to what you might see if you’re looking out of the window in Ten Forward on the deck of the Enterprise at impulse speed). Rather than include a looping video file in the game, I decided to procedurally generate it. The result was a custom Canvas control called StarFieldCanvas. I’ve uploaded it to my GitHub account. Feel free to check it out: https://github.com/gkjpettet/StarfieldCanvas. It comes with a simple demo project illustrating how you might use it.
