Scratch

I know that lists are the only current implementation, but they act in a way that is similar to an array. I really hope they DO choose to incorporate Jens' lists, in the exact same style, but perhaps go through and fix any glitches. Another possible idea would be to make a visible array, like an Excel spreadsheet, that would function in a similar manner.

Absolutely! A visual representation of a list/array would be fantastic, so you could view and edit lists interactively the same as you can view/edit a variable watcher.

Hey, just curious scratch team, but I have the beta, and are the visual aspects of the lists inspired by my earlier post? Just wondering. It would be awesome if something I said affected how Scratch turns out

Question:What are arrays and what do they do?

Arrays are variables that store groups of data.

Using arrays you can make a mouse recorder.

//like this
forever
set mouseX at (i) to (mousex)
set mouseY at (i) to (mousey)
change i by 1
end

If you did this every time the code is executed it would save the position of your mouse to the array.

To play it back you would do this.
//put this one the fake cursor sprite
set j to 1
repeat until (j=i)
goto x:(mouseX(j) y:(mouseY(j)
end

Arrays have many uses.

j+1

Forgot to add 1 to j. What's the point of repeating it at position 1 XD  ?

You need to start at array position 1 to play it back.

I see many possible uses for arrays. I will keep my big project a secret until it is totally done, I have started work on it using the beta........

Yeah, but you need to go to a new position in the array each tiem through. What you wrote was to play position 1 of the array over and over XD

Lol my bad. I forgot to put "change j by 1"

oh yeah, you don't use j+1 in Scratch XD. I almost put J+= 1;

Are there projects that simulate arrays?

Yes but none are really as good as actually having arrays.

Teh only reason I thought it might have been my idea was cause Jens liked it, and he is in close contact with teh scratch team. It is probably the scratch team's idea lol

Here is another array project I made: http://scratch.mit.edu/projects/Cyclone103/174713 it uses an array to store block info.
