Scratch

First, this shouldn't go in requests. It should be in All About Scratch.

Anyways, you would first make 2 lists and call them "x" and "y" and also make a variable called "list number".


Then you do,
When mouse is down
<repeat until mouse is not down>
add mouse x to "x"
add mouse y to "y"
</repeat until mouse is not down>

Then, on the Santa Sprite,
you would do this:

<flag clicked>
<set "list number" to 0>
<forever>
<if>
<mouse is down>
<wait until mouse is not down>
<repeat -length of x-
<set x to <item "list number> of x>
<set y to <item "list number> of y>
change "list number" by 1
</if>
</forever>

And that should do it!
