Hi
My project is giving the wrong results, when a stamp goes over a previous position x and y of another stamp.
How could I make this concept work, by stamping only in positions of x and Y, that have not yet been stamped previously?
I made a position of the X and of the Y each 60 and 80 steps.

See my project:

Thank you!

There are several ways. One way is to use lists to keep track of the positions and which have already been used.

Make list ‘previous positions ’and variable ‘position’.

when I start as a clone
go to [ random position]
set [ position] to [(join (x position) (y position)) ]
if <[ previous positions] contains [(position) ]> then
    
delete this clone
end
if <<not <[ previous positions] contains [(position) ]>>> then
    
add [positions] to [previous positions]
end
end

Replace the 2 ifs with if else condition.Hope it helps.Sorry for horrible script.I'm not good with scratchblocks on the forum.

Hi Thank you!
Seems I'm not ready yet for the lists… need to work further on it. I've changed it to work instead with Clones.
I will see if If I can improve it later with the suggestion above for the position, to be able to use a random place in the play field.
