Hi! So I'm doing a school coding project and I need help with knowing how to have the player at a certain scene be able to use a pen that is controlled by their mouse. For more details I have a cross word puzzle and I want them to be able to circle the words with their pen. Im also wondering if there's a way if the person messes up with the pen that they can revert their mistakes and let them start again.
Edit: So I was wondering when the player is using the pen and makes a mistake they can revert their last move with the pen instead of reverting everything by using the "Clear" Code in pen.
