Detect capital/lowercase keys with <when key pressed> block

Fuzzee_animations

Hello! Is there a way to make the <key pressed> block case sensitive? I tried with costumes and fiddled with that for a bit, but with no luck. Is there a way to be able to detect whether the user types a capital or lowercase letter? Thanks!!!

It isn't possible. The shift key is not detected and there is also no differentiation for case if a letter was typed into the input. The only thing close is that some symbols that typically require holding shift can be detected.

You can see the code here: https://github.com/scratchfoundation/scratch-editor/blob/develop/packages/scratch-vm/src/io/keyboard.js

there is a solution, that is that costume names are case sensitive!

But how specifically would you go about doing this? I have a sprite with capital/lowercase costumes, but I haven't figured out how to make it actually work. Thanks!

switch costume to [ (foo)]
if <(costume numebr) > [blabala]> then
capital
end

this is if the capital letters are at the bottom of the costumes

Right, that works for detecting the capital, but how can you make the keypress case sensitive with that?

when green flag clicked
set [shift] to [shift]
 forever
if <key (shift) pressed?> then
if <key [any] pressed?> then
your code here
end
end

This does not work for me on standard Scratch. Are you using some modified version of Scratch?

Even using an extension, I can't find shift.

this does not seem to work for me either.

just use the prompt function already
also why do u need to detect capitals

There is no coded way of getting the code blocks to detect the shift key or the caps lock. You either have to implement a shift key as a sprite for players to click, use the question and answer block, have an alt key equal to the shift key (i.e up arrow) or leave it be. Scratch just never put the shift key into their coding system. I believe Turbowarp did but not Scratch.

Yes, but that only works if you are using the ask/answer blocks. Scratch can’t differentiate lowercase and uppercase key presses.

try making a different key shift? like dedicate a specific key to shift

<key (join [en] [ter]) pressed?>

if <key (join [en] [ter]) pressed?> then
if <key [any v] pressed?> then
your code here
end
end

the owner of this topic already said that! I just didn't read the title correctly

Only enter can be detected this way. Not shift.
