Question

I am trying to create an application that simulates a slot machine.

Now, I have all the images ready, with the vertical png file and the plist file. My question is, how do I simulate the spinning (when the user presses a button), and then the stopping of the slot machine (after around 1-2 seconds)?

Note that the png file has to wrap around somehow.

Everything else is all a matter of NSArrays and checking, what I want to figure out is the animation. I hope some can share some code or references to do this.

Thanks!

Answer 1

This is relatively straightforward: just repeat the png file as many times as you need to simulate the spinning action. So it’s basically a vertical variation on parallax scrolling. If you have Steffan Itterheim’s book, he talks about this type of thing in chapter 7 “Scrolling With Joy”. You may also find some help here: Cocos2D vertically scrolling background

Hope this helps!
