问题
I'm working on a game copter (http://i1-games.softpedia-static.com/screenshots/Copter_1.jpg). When you touch the screen, you go upwards otherwise you'll go downwards. So you are changing the position of the sprite.
Now I want a trailpath for my sprite, does anybody who has an idea how to do it? Here is an example of how it should look like:
Tips for on the center line are good enough. If you have an idea how to do the gradient, let me know!
