I want to make a blueprint uneable to use

[RealDidacticus]

I am new to this, I think this should be an easy question but I have no clue. Basically you go to give the mail and you enter a widget to either send the letter or read it, if you send it, the widget disappears if you read it the letter appears momentarily and then it disappears.

Now, you should not be able to see the widget again, because you already read it/send it, but I don’t know how to eliminate the option to see the widget (you get into the widget by pressing E near the mailbox, I want the player to be able to do it, but only once).

Well, you got several options to do this, but perhaps the easy one is use the “Do Once” node. This node only let you pass across a code once, so only one time can be executed.
