A fast, easy to use, free, and community supported 2D game engine
Hey everyone,
I'm wondering what a possible fast alternative to NSMutable array might be?
It's basically going to store an array of points for about 200 objects (each with their own), and will be enumerated every frame.
I notice the engine uses ccArray, and was wondering if maybe I should give that a try.
What's does normal usage of ccArray look like for adding and removing objects?
I know NSArray is much faster than NSMutableArray, so what you can do with minimal code changes is populate a temp NSMutableArray and then copy the objects into an NSArray:
NSArray *shapes = [[NSArray alloc] initWithArray:tmpshapes];
I do this because NSArray has to be populated when instantiated. The rest of the access methods are the same.
See CCParallaxNode.m or CCActionManager.m. They use it internally.
I want to stuff a bunch of CGPoints into it to store the path info, but i'm getting
'incompatible type for argument 2 of ccCArrayAppendValueWithResize'
Should I make an NSObject wrapper that basically contains the CGPoint i'd like to store?
CGPoint is not an objective-c object. If you want to use C structures instead of objective-c object, you should use ccCArray instead of ccArray.
In my example above, i am using ccCArray, but it's still giving that complain.
I thought 'id' could accept anything?
I made a wrapper (actually literally copying your point object in the parallax class) - thanks for the help :)

Id highly suggest using a vector. They will be the fastest mutable array.
