Creating a Sprite using UIImageView...

[kmadhukishore]

Hi all,
I am planning to write a game based on Quartz 2D..
And following is the code for managing sprites,Of course constructor I will change accordingly for dynamic behavior by passing animation ID and manipulating the data:

#import <UIKit/UIKit.h>

class SpriteObject
{
public:
	SpriteObject(UIView* parentView);
private:
	UIImageView* spriteView;
};


#import "SpriteObject.h"

SpriteObject::SpriteObject(UIView* parentView)
{
	spriteView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, 0.0,100,100)];
	NSArray* myImageArray = [[NSArray alloc] initWithObjects:
							 [UIImage imageNamed:@"1.png"],
							 [UIImage imageNamed:@"2.png"],
							 [UIImage imageNamed:@"3.png"],
							 [UIImage imageNamed:@"4.png"],
							 nil];
	spriteView.animationImages = myImageArray;
	spriteView.animationDuration = 2.0;
	spriteView.contentMode = UIViewContentModeCenter;
	[parentView addSubview:spriteView];
	[spriteView startAnimating];
}

And in the main view controller class i am doing this:

- (void)viewDidLoad {
    [super viewDidLoad];
     
     //Creating animation	
     new SpriteObject(self.view);

     [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(onTimer) userInfo:nil repeats:YES];
}

-(void) onTimer
{
        if(/*Some condition*/)
{
[spriteView stopAnimating];
}

	mySprite.center = CGPointMake(mySprite.center.x+pos.x,mySprite.center.y+pos.y);
	
	if(mySprite.center.x > 320 || mySprite.center.x < 0)
		pos.x = -pos.x;
	if(mySprite.center.y > 460 || mySprite.center.y < 0)
		pos.y = -pos.y;
}

And I will
1)Create all Spites in the beginning of the game and I will add them to my View.
2)And each sprite is a UIImageViews etc.,.

Is this an efficient way??Or is there another nice way for managing sprites??

If I am not clear please tell me...

Thanks in advance....
Madhu.

I used this technique.. and it worked pretty well...
Using a GIF is not very efficient on iPhone. Apple recommends only PNGs as the quarz composer is optimized for PNGs...
