I'm trying to make a game, and there's a list called colors and, i need it to go through itself again. I'll upload it.

Re: How to make a list go back through itself!

Use:

when I receive
gothrough
set
i
to
1
repeat
length of
colors
do stuff
change
i
by
1

Or:
when I receive
gobackthrough
set
i
to
length of
colors
repeat
i
do stuff
change
i
by
-1

If you want to reverse the order of the items in a list, use this:
when I receive
reverse
set
i
to
length of
colors
repeat
i
add
item
i
of
colors
to
templist
change
i
by
-1
set
i
to
1
repeat
length of
templist
replace item
i
of
colors
with
item
i
of
templist
change
i
by
1
delete
all
of
templist

It should work...

Programming is an art...
Goodbye, Scratch. I am leaving because of the exams coming up at our school, though I'll check the forums once or twice a week.

Re: How to make a list go back through itself!

What do you mean by "go through itself"?

I want the script to clone (more like stamping) the sprite and I want it to be a 1s1s project

Re: How to make a list go back through itself!

Cloning is currently impossible in Scratch (at least, without "hacking").  I'm still not sure what "going through itself" means.

i mean like if you have a list and you want it to go through and pick out different colors and draw the results... like if you have green, and you want the sprite to draw the color.

You can't select color based off of variables directly in Scratch (I believe you can in Panther though).  A more efficient approach than the if-else statements may be to use the block:

set pen color to
item
i
of
list

Thanks I've tested it, and it worked great. But there's a problem. I was trying to upload it, but it went on forever. (I had to force quit it.) Could you possibly make it so that it doesn't have repeat blocks, if it's possible.

For this one, you can't put a () block in a color.  smile

There are two "set pen color to" blocks.  One accepts "round" blocks and the other is the color square.  For the color square one (first one mentioned above), you need to use if-else statements and manually set the color.  For the second one, you can change the color by setting it to a variable's number.

Also, when I said "set color to [green]", that was using the color-square-block.  I don't know how to put in actual colors with the scratch blocks  smile

Re: How to make a list go back through itself!

I don't think that's necessary in this case.  I didn't really give you a concrete script, and, if you use the second method, all I did was point you to a block.

Re: How to make a list go back through itself!

I tried using MoreGamesNow's script with his/her's block
Here is the result http://scratch.mit.edu/projects/coolhogs/2355713 It won't work. Can anyone fix it for me?
