Miles,
Right!
I have drawn a circle as you sugest but I still have some difficults about how to acess my coordinate data.
My circle is just a simple circle.
My big difficult is how to interage with my blobs.
If I want push the circle for example.How can I do this?Which name of the "Guy"responsable for it"?Where Do I write it in my code?
Could you suggest me something?
Thanks for the help.
