Put a target on screen. When I click it, it jumps somewhere
else and my score goes up. If I miss, nothing happens except
that I feel bad.
Write your requirements list before you write any code. What the player does, what happens on screen, and every question the brief did not answer.
Notes
Session 13 gives you the click and where it happened. Working out whether that point is inside the target is the actual challenge.
A point is inside a circle when its distance from the center is less than the radius. math.sqrt exists; so does comparing squares if you would rather not use it.
A rectangle target is an easier and completely acceptable answer. Say in your list which you chose and why.
Somewhere else should not be the same place twice, and should not be half off the screen. math.random needs bounds.
Call math.randomseed(os.time()) once at the top, or every run is identical.
What Success Looks Like
The target moves only when it is actually clicked
Clicking the background does nothing at all
The score is correct after ten clicks and ten misses
The target never appears partly outside the window
Click just outside the edge of the target. That is where a hit test is wrong if it is wrong.
