Hello.
I have a problem with this block. When I Put:

when green flag clicked
if <key [ v] pressed?> then
    
switch costume to [ v]
end
else
switch costume to [ v]

when i press the key the costume changes (to “run”) but when i don´t press the key any more the costume doesn´t changes(still the costume “run”) and it is like if i am pressing the key still.
Any idea about why it happens?

You need a forever loop around your script otherwise it will just run once and end.

Thank you so much, it works now.
