How to replace images in a puzzle game

Question

I am making my first game as a simple puzzle game.

i mew in the game program.

i put image 4 in the view to assign them images, cropping one original image with this code.

int partId = 0; for (int x=0; x<=200; x+=100) { for(int y=0; y<=200; y+=100) { CGImageRef cgImg = CGImageCreateWithImageInRect(whole.CGImage, CGRectMake(x, y, 100, 100)); UIImage* part = [UIImage imageWithCGImage:cgImg]; 

to get the viewing position of the image in the view, I use this code

 - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { // get touch event UITouch *touch = [[event allTouches] anyObject]; CGPoint touchLocation = [touch locationInView:self.view]; NSLog(@"%f %f",touchLocation.x,touchLocation.y); 

Now I need that ever one kind of image approaches another representation of the image, then I need to exchange my positions.

for example: part1 go through part2, then part2 to place1 of part one and part1 to place part2.

How can I do this, can someone help me.

This is the right approach to make this puzzle.

Thanks in advance.

Well, since you use images, you need to implement collision detection logic in your project. try some of the codes at http://apress.com/book/downloadfile/4587 . he has very good examples of collision detection, and he is free.

and try reading this game development book on iphone
