This tutorial explains how to use the pen blocks to draw with the mouse through a sprite. The following method, using a sprite that follows the mouse, creates the effect that the mouse is making the drawing.
How to Do it
Here is the script that allows you to do so:
when flag clicked pen up clear forever go to [mouse-pointer v] if <mouse down?> then pen down else pen up end end
|Tip:||To make it seem as if the mouse was drawing and not a sprite, try setting the sprite's ghost effect to 100 or hiding the Sprite (You can also leave the sprite blank, so you don't have to do these things) .|
