Fireworks simulation on iPhone
Filed in: iPhone apps Add comments
A while ago, i created a pretty basic particle system to create some fireworks, recently i did some changes, and created a simple demo application for the system.
Here is a demo :
Also i’ll add the source code here, asap. Mean while take a look and admire the view 
.
Fireworks source code – here is a zip with the source code, have fun playing with it, and remember to give me the credits if you use it in your projects .

I really enjoyed your demo on the Fireworks. Thank you. Is it possible to insert a png of stars to the fireworks rather than the squares you have in your demo? What do I have to do to add that? Thanks for your help. Pete
Also, this part of the code says that there is potential leak in aFireWork.
“aFireWork = [[FireWorks alloc]init];” in:
- (void)resetFireworks:(NSTimer*)theTimer {
NSLog(@”enter”);
CGRect currentFrame = fWView_.frame;
FireWorks *aFireWork;
aFireWork = [[FireWorks alloc]init];
aFireWork.origin = CGPointMake(arc4random()%((int)currentFrame.size.width), arc4random()%((int)currentFrame.size.height));
[aFireWork generateParticles:100];
[fWView_.fireworks addObject:aFireWork];
if([fWView_.fireworks count]>10) {
FireWorks *firstFireWork = [fWView_.fireworks objectAtIndex:0];
[firstFireWork removeSistem];
[fWView_.fireworks removeObjectAtIndex:0];
}
}
