How to add multiple sprites with time interval of 3 seconds and run same CCAction for all in cocos2d

Question

Please help me as am fed with the searches and new to cocos 2d. Only am getting is the last sprite got moving if i schedule addRed and i want all the sprites moving randomly in the screen. Any help will be Appreciated and thanks in advance.

-(void)addRed 
{
redSprite = [CCSprite spriteWithImageNamed:@"Red.png"];;
CGSize screenSize = [[CCDirector sharedDirector] viewSize];
[redSprite setPosition:CGPointMake(screenSize.width/2, screenSize.height/2)];
[self resizeSprite:redSprite toWidth:80 toHeight:80];
[self addChild:redSprite z:10];

[self gameStart];
}

- (void)gameStart {
    // Create the actions
CGSize result = [[UIScreen mainScreen] bounds].size;
CGPoint nextPoint;

if (redSprite.position.x == result.width-40.0) {
    nextPoint.x = redSprite.position.x - kAccelXAxis;
    backx = YES;
}
else {
    if (redSprite.position.x == 40.0) {
        nextPoint.x = redSprite.position.x + kAccelXAxis;
        backx = NO;

    }
    else {
        if (backx) {

            nextPoint.x = redSprite.position.x - kAccelXAxis;
        }
        else
        {
            nextPoint.x = redSprite.position.x + kAccelXAxis;
        }
    }
}

if (redSprite.position.y == 40.0) {
    nextPoint.y = redSprite.position.y + kAccelYAxis;
    backy = YES;

}
else {
    if (redSprite.position.y == result.height-40.0) {
        nextPoint.y = redSprite.position.y - kAccelYAxis;
        backy = NO;

    }
    else {
        if (backy) {
            nextPoint.y = redSprite.position.y + kAccelYAxis;
        }
        else
        {
            nextPoint.y = redSprite.position.y - kAccelYAxis;
        }
    }
}

    CCAction *myAction = [CCActionSequence actions:[CCActionMoveTo actionWithDuration:0.01 position:nextPoint], [CCActionCallFunc actionWithTarget:self selector:@selector(gameStart)], [CCActionCallFunc actionWithTarget:self selector:@selector(updateCol:)],nil];
[myAction setTag:10];

[redSprite runAction:myAction];

}

Try creating a updater with an interval of 3 sec for creating your sprites. For your created sprites, use a CCRepeatForever which will generate your next positions for your sprite.

For your case, I also thought about using a custom CCSprite to store your next position to move.

You will need something like...

   [self schedule:@selector(createSprite) interval:(3)]; //to schedule your sprite generator

// Your sprite generator with action
-(void)createSprite{
    CCCustomRed *red = [CCCustomRed spriteWithFile:@"red.png"];
    [self addChild:red];
    CCCallFuncN *changePos = [CCCallFuncN actionWithTarget:self selector:@selector(setRandomPos:)];
    CCMoveTo *move = [CCMoveTo actionWithDuration:1 position:red.nextPosition];
    CCDelayTime *delay = [CCDelayTime actionWithDuration:1.0];
    [red runAction:[CCRepeatForever actionWithAction:[CCSequence actions:move,changePos,delay,nil]]];
}

//Generate a random pos as your sprite next move
-(void)setRandomPos:(id)sender{
    CCCustomRed *red = (CCCustomRed *) sender;
    CGSize screenSize = [[CCDirector sharedDirector] winSize];
    red.nextPosition = ccp(arc4random()%screenSize.width,arc4random()%screenSize.height);
}

Hope it helps :)
