I was thinking of make a slider/joystick but not in a circle but in a line. So I made the image drag able only over the X axis and when it gets to the point where the slider stops i did this :
if(slider.center.x <= 60) {
slider.center = CGPointMake(60, slider.center.y);
}
so it wouldn't get bigger than 60 but i was thinking isn't there a better way to do this? like make a boundary box and setting up something to not drag it outside that box?
Thanks!
