Hi, Karl - With your permission, I'd like to put this Etoy on the Squeakland site for further sharing and distribution. What would be really helpful to novices taking a look at the project would be if you could add some text explaining what you did and what the elipse does and why it does it. (What is the purpose of the blue rectangels in the holder?) It would be great to have a little introduction and explanation about the parts of the Etoy. Would you be willing to add a bit more info and share another version that we could add to the Squeakland website? thanks! Kim

I'm working on it. The blue rectangles in the holder holds instance variables with former x and y values of the ellipse. Each time the ellipse moves forward it adds a new rectangle to the holder. That makes the backtracking possible. Etoys sure are fun :-)

Here is the project with a little documentation. http://www.squeakland.org/project.jsp?http://squeakland.org:8080/super/uploa...

Oh, a quick update: Here is the project with a little documentation. http://www.squeakland.org/project.jsp?http://squeakland.org:8080/super/uploa...
This is the version you want to use. Look at the cool garbage collecting :-)

Fun!
However, it only backtracks by one square, so it gets stuck easily. In script3 you set the cursor to 1 and then increase it; what you probably want to do is move the resetting to 1 somewhere else, or just throw away the history after backtracking.

No, what is missing is to move the first stack item to the trash holder.
The cursor increase is just to test if the stack is empty - there seems to be no other way to test the size of a holder.

Right Most stuff should be fixed in this version: http://www.squeakland.org/project.jsp?http://squeakland.org:8080/super/uploa...

Right again.

Karl, very cool. The documentation is well written, as well; can I re-use?
Anyone else with internally documented (or not) projects not published to the super swikis? I would love to see anything you are willing to share.
Thanks,
John

I wrote a 'how to make a etoy space invader' some time ago. It's on Bob's SuperSwiki or Squeakland SuperSwiki. I'm going to go through it today hopefully and update it if nessesary.

It might be a little more intuitive if you put in a special player that signifies "empty" -- this was often used in the sixties for stacks, especially in mathematical explanations of stacks, etc.
Cheers,

Good idea. I'm adding and deleting from the top of the holder so the last player could be dot for example and when that is the first player in the holder it's empty.

I am a newbie in squeak and etoys and explore the projects to learn. With this project I have two problems in understanding, I can not solve myself. Perhaps someone can help me:
1.) If I have a look on the rectangles inside the Holder, there are the rectangles with the names Rectangle1, Rectangle3, Rectangle4, Rectangle5 and so on (the number increases by 1). But never the Rectangle2 is visible. What's going on there?
2.) In Script "writePosition" is the tile "Holder include at beginning" is used, but I can not find that in the viewer of the Holder. I can only find "Holder include" in the collections categorie. Where can I find the used tile?
Thanks for the help
Thomas

Seems to be something of a internal Player issue and I'm not really sure why it happens. Could be that Rectangle2 is already in the project somewhere...

Ugh, seems to be a Squeak 3.6 feature, not currently in the plugin image. My fault. I shall not write tutorials for Squeak plugin image using Squeak 3.6. I shall not write tutorials for Squeak plugin image using Squeak 3.6. I shall not write tutorials for Squeak plugin image using Squeak 3.6. ...

Ned Konz gave me a tip: Uncheck the preference etoyFriendly in the Preference tool. You find the Preference tool in the tools section in the Objects Catalog in the Supplies flap. etoyFriendly is in the scripting section in the Preference tool.
The wording of the tile is 'holder prepend dot'
