Consider being a bit more descriptive, you’ll get a better answer, faster.
Oh sorry im gonna trying being a bit more descriptive. I want to make widget appear when you are inside a box trigger and then disappear when i press a key or walk out of box trigger. Hope this was better. So i will explain it again i want a actorbeginoverlap (Box trigger) and an actorendoverlap (Box trigger) and i want it to disappear when i press a certain key.
Hope this helps.
Do exactly what Everynone said,. But also add an endoverlap event for making it disappears,. Then add a key event and plug the white pin into the same pin as the end overlap. I think I made a tutorial once that had this exact situation in it, if you go to https://YouTube.com/vic3vers4games watch my old grafitti tutorials they should walk you through the process.
