I have this ticker that scrolls text left to right in a project, but I would like it to scroll in the other direction (right to left). Is this possible without to much or slow code?

when I receive [ticker v]
set [Commands v] to [A=&, O=|, X=^, C=~, ←=<<, →=>>, P=+, M=-, T=*, D=/, U=%, N=(-), S=swap, ↑=roll up, ↓=roll down, 1-9=# digits, R=reset, E=enter, ]
set [_commandsStore v] to (Commands)
set [_lenCommands v] to (length of (Commands))
forever 
  set [Commands v] to (join (letter (_lenCommands) of (Commands)) (Commands))
  wait (0.3) secs
  if <(length of (Commands)) > ((2) * (_lenCommands))> then 
    set [Commands v] to (_commandsStore)
  end
end

I happen to have a project that scrolls text right to left. Maybe some of it will be useful to you… https://scratch.mit.edu/projects/103427939/

It's interesting that you use one clone for each letter in the shown text. I would prefer if I could scroll a variable-box from right to left since it is less job to include any UTF8-characters in the text.

Start creating a variable containing “space” characters until you fill the screen width, then go replacing last character with the first letter of your string and moving those you replaced previously 1 position and adding the needed “spaces” until it backs to original(all spaced) when the entire string you want scroll has be showed.

Thanks! This shows that it is possible to do it rather fast, but this does not roll around like I wanted. Now I did this in Bitwise Calculator Hexadecimal Decimal Octal Binary:

when I receive [ticker v]
set [Commands v] to [A=&, O=|, X=^, C=~, ←=<<, →=>>, P=+, M=-, T=*, D=/, U=%, N=(-), S=swap, ↑=roll up, ↓=roll down, 1-9=# digits, R=reset, E=enter, ]
forever 
  wait (0.2) secs
  roll_commands :: custom
  set [Commands v] to (join (_commandsStore) (letter (1) of (Commands)))
end

define roll_commands
set [_commandsStore v] to []
set [_letter# v] to [2]
repeat ((length of (Commands)) - (1)) 
  set [_commandsStore v] to (join (_commandsStore) (letter (_letter#) of (Commands)))
  change [_letter# v] by (1)
end

Procedure roll_commands should run without screen refresh.

Maybe this can be improved.
