Mutable Array and Sprites

I'm making a "snake game" like player and I have the body moving fine so that it adds a block in the previous position each time it moves up to 4 then it removes the last one... etc. I'm adding each block to a NSMutableArray (each block is a sprite and I add the sprite to the array) and I was wondering how to get the position of one of the sprites in the array. I need this so I can check to see if the "head" is trying to move onto itself.

P.S. I'm using cocos2d for iPhone.

When I say position I mean the coordinates, not the index position in the array.

[tail insertObject:block atIndex:i];
[self addChild:[tail objectAtIndex:i]];
i +=1;
CCSprite *sect;
for (int j = 0; j >= i; j++) {
    sect = [tail objectAtIndex:j];
}
if (i > maxHealth) {   
    [self removeChild:[tail objectAtIndex:i-maxHealth-1] cleanup:YES]; 
    id object = [tail objectAtIndex:i-maxHealth-1];
    [tail removeObject:object];
}

When the scene is started i is set to 0 and the max health equals 3.

Are you asking how to put a variable into an array? or are you asking how to get the position of the sprites? – Just a coder
How to get the position of the sprites inside the array. – stenger96
Do you already know how to get the position of the sprites? and do you know how to store an object into an array? – Just a coder
Yeah? sprite.position; and [array insertObject:object atIndex:i]; – stenger96

Get the position of a node in an array? Like

// Get the node from the array
CCNode *node = (CCNode*)[myArray objectAtIndex:0];
// Retrieve the position
CGPoint nodePosition = node.position;
