group objects

Apologies if I've asked this in the past and forgot... am I able to
group/join together multiple objects into a composite object? I'd like to: - paint a fat line - script to: rotate it and make copies - treat all lines as a single object thanks, Randy _______________________________________________ Squeakland mailing list [hidden email] http://squeakland.org/mailman/listinfo/squeakland |

Draw the fat line on top of it. From the Line's halo menu choose "embed into ... Rectangle". Now when grabbing the rectangle, the line moves with it. Then make a script like "Line turnBy: 30. Rectangle include: Line's copy." and you're fine to go. - Bert - _______________________________________________ Squeakland mailing list [hidden email] http://squeakland.org/mailman/listinfo/squeakland |

Thanks Bert. Ah yes, it's coming back to me. However, don't I need
to use a Playfield as my "container" object? I followed your instructions - drawing a rectangle and embedding my line into it. But then I couldn't find a "rectangle include" tile in any of the categories - is it there and I just missed it? In a playfield, it's in the Collections category.

I'm posting to my earlier reply that hasn't appeared yet...
unfortunately, just embedding a copy of the line into a playfield doesn't accomplish what I want either, i.e., it doesn't give me a single composited object. Here's a concrete example that I'd love for someone to explain how to accomplish in Squeak (it goes back to my desire to do a project involving symmetries): - paint 1/6 of a snowflake - rotate it, make a copy, and "embed" into "snowflake" object - repeat Once you have a complete snowflake, write scripts for it.

Err, you're right - use a playfield to construct the script. However,
once the script is there, you could actually replace the playfield tile with a rectangle tile and it will still work. Or even better, drop a "line's holder" tile into its place ... This is what I did when I tried it. The reason I preferred a Rectangle is that you can pick it up with all its contents. For a playfield you would have to fiddle with its options in the halo menu to achieve this. - Bert - On Mar 10, 2007, at 12:54 , Randy Heiland wrote: > Thanks Bert. Ah yes, it's coming back to me.

While you can select all the objects if you hold down shift and drag over them, there is no option to group them Karl _______________________________________________ Squeakland mailing list [hidden email] http://squeakland.org/mailman/listinfo/squeakland |

And of course, you can get out a playfield, fiddle with its options
to allow it to be picked up, make it transparent, etc., then put it back in supplies, and it will form a prototype of this kind of playfield. You can also use shift-drag to pick up a group of graphic objects to put them in the playfield. (This could be a smoother smarter operation than the current situation in Etoys.)
