After some disconcerting bugs were dealt with, and a rework of the way elements are defined, I have to rework dragging. Funny, right?

How do you drag an element onto another?

I check for ONLY the first frame of when the screen is touched, then in that frame I get the first sprite that contains the cursor coords. After that, I get the offset between my cursor and the sprite position.Then for the rest of the time that the screen is touched, I move the sprite to the cursor plus the offset I collected before.When I lift the stylus from the screen, I reset everything.

I then check while the screen is not touched if elements are those in any recipe, and if they are, I check if they are colliding. If so, I delete both and make a new sprite with the resulting element type.
