In the Playfield's Viewer -> Category: playfield
mouse's X and mouse's Y
*QUESTION*: Is this the mouses position in relation to the "Playfields"
origin?
Please help me distinguish
- *Playfield:Viewier->Category:collections->graphic at cursor*
- *Playfield:Viewier->Category:playfiled->graphic*
It 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<http://www.squeakland.org/launcher/?http://www.mrstevescience.com/Etoys/Fun%20With%20Playfields.010.pr%20>(its
a work in progress, suggestions welcome).
