Hi,Steve,
painting on a playfield adds a sketch with the painting to the playfield,
You can easily verify that by right clicking, first you get halo for the playfield,a second click gets the halo for the sketch,
You can even pick the sketch with the black handle or move it in the playfield with the brown handle.

Subject: Re: [squeakland] Playfield Questions
In the Playfields Viewer -> Category: playfield
mouses X and mouses Y
QUESTION: Is this the mouses position in relation to the "Playfields" origin?
Please help me distinguish
Playfield:Viewier->Category:collections->graphic at cursorPlayfield:Viewier->Category:playfiled->graphicIt seems the "Playfield:Viewier->Category:playfiled->graphic which can be set via Halo:Paint Background and via assignment in a script is meant to be a "Background"
That makes sense to me but here is my concern/lack of understanding . . .
Why is it when I add a Background Image, the Playfield:Viewier->Category:collections->graphic:count Increases?
IE, If I try and iterate through the items in the Playfield with the cursor and there is a background, I will get the background sketch as the first item in the list. I would think the "Background Sketch/Graphic would not be part of the "Collection".
I created a Etoys project to test this go to page 2 of Fun With Playfields (its a work in progress, suggestions welcome).
Stephen
