Hi, you should grab a playfield from the supplies flap and draw you background in the playfield, then put your car inside the playfield and the pen trails should be above the background.
Hi, I think this is a bug. The pen trails work different in a playfield than in the world. In the world the background morph is draw above the pen trails, but in the playfield the pen trails are draw above the background. I believe the latter is the correct.
I looked at the code briefly and I couldn't find the error. In fact, it's weird because if I evaluate
World drawOn: Display getCanvas
in a workspace the pen trails are draw correctly. Any ideas?

I have a 'racetrack' sketch that is supposed to work as a 'stage' as in Scratch. The car drives on this racetrack and needs to leave a pen trail. The pendown writes onto the main screen area, underneath this racetrack 'stage'. How do I create two sketches - one serving as a 'stage' /background, and the other as the 'sprite' to move and leave pen trails on the first sketch.

I seem to have found a fix by modifying PasteUpMorph>>privateOuterDisplayWorld to leave the background morph out, like this:
privateOuterDisplayWorld
worldState displayWorld: self submorphs: (submorphs copyWithout: backgroundMorph)
This seems to work but I fear the cost of making a copy all the time could be too high (I haven't checked, though). Another idea would be to never add the backgroundMorph to the World's submorphs but this could be even worse and it's not consistent with the playfield's case.
What do you think?

I found exactly the same fix :)
Let's hear from Scott what he thinks.

I have always had a little problems with the pen trails. They have not had a first row seat and that have bothered me a little. But I'm not sure what I want instead.

Excellent… but we should only do the "copyWithout:" in the comparatively uncommon case of the backgroundMorph's actually being notNil…
Great finally to get consistency between playfields and worlds here :)
