I made a quick concept for our next game,
with
Record the location of the initial touch and have a small sprite that moves to the touch position X & Y on touch end spawn the object on the initial touch coordinates and loop a scale 1.1 of object until it collides with the small sprite.
To draw lines you can spawn an object to touch.x & touch.Y (i think) This might kill performance though
That's how i've done it i cant post the event sheet as i'm at work, but i believe this is the way to go without using addons (there may be an addon to help you)
