The great guys at 71 Squared, creators of these brilliant iPhone game programming tutorials with video have recently updated their excellent particle designer. You can see a video showing how easy it is to use here:
If you’ve gone through the tedious process of tweaking particles so that they fit right in this game you are going to love this. It allows you to easily tweak a multitude of particle settings in real time so that you can get things right quickly.
What’s even better is that with the latest updates to the designer and Cocos2D it now integrates easily with Cocos2D and supports the iPad!
It costs $7.99 (once you see the quality of this program you’ll be surprised they sell it so cheap), but has a free trial.
You can find the free trial here.
