Hi, I wish to create a global dynamic array of sprites something like this
I wish to define in .h
CCSprites *tempArray[]; // (this gives error in my project when i define it.)
and in init() function of .m
i wish to initialize it like this
tempArray = new CCSprite[x]; // where x is any dynamic number of array.
I know it can be done using NSMutableArray but I need to create dynamic array of sprites
how can i do that?
thanks in advance

"I know it can be done using NSMutableArray but I need to create dynamic array of sprites" NSMutableArray *is* a dynamic array. You are almost definitely better served by using NSMutableArray.
But you could use a C++ vector, or a c pointer (with malloc and free) if you want. *But* remember now memory management is going to be more work - its up to you to retain objects that go into your array and release them when they leave.
Look in 99.4 in "support/data structures" for the ccCArray and CCArray - it uses a c array in an ObjC wrapper as a NSArray replacement.
Why dont you want to use NSMutableArray again?

What I was trying to do actually I did it using NSMutableArray.
The reason for not using NSMutableArray was actually I had some limited enemies 4 to 8. I wanted to compare their rectangle with the missile of hero. after they have been detected then i had to remove them. Actually I wanted to identify them uniquely.
and I did that using this code. :)
CGRect MissileRect = [self rectForSprite:Missile];
for (int i=0; i<[Opponents count]; i++) // Opponents is NSMutableArray
{
CCSprite *tempSprite = (CCSprite *) [Opponents objectAtIndex:i];
CGRect OppRectangle = [self rectForSprite:tempSprite];
if(CGRectIntersectsRect(OppRectangle, MissileRect))
{
[bg removeChild:tempSprite cleanup:YES]; // this removed them from game play
[bg removeChild:Missile cleanup:YES];
[Opponents removeObjectAtIndex:i];
}
}thanks for reply
