Re: Drag and Draw

[Henry Wilson <henryhwilson@xxxxxxxxx>]

I actually did that for a project one time. Here is the code

to start
show
setpenuptext "pu
forever [setpos mousepos]
end

to blue
setc "blue
end

to green
setc "green
end

And any other colors that work (you have to test it.)

Anyway, you should put a button for each color on the page, a button  
for clean, and a button for start and stop.
You must have a textbox called penuptext.

In a turtle, make mini size. then put a code in backpack

to startit
if penuptext = "pu [pd setpenuptext "pd stop]
if penuptext = "pd [setpenuptext "pu pu stop]
end

Put startit in the onclick part of the rules in backpack.

To start, click on start button. Move mouse around. Click when you  
want to draw. You will draw until you click again. When you are not  
drawing, you can change your color by clicking on a color button.
Hope this helps

Henry
