Missing Event Graph in Blueprint

I keep getting “Folder is locked” when trying to edit a blueprint script. I have completed the first hour in UEFN pretty basic but I can’t figure out how to make a sphere disappear on collision with a weapon projectile.

Could you point me in the right direction for how to learn this UNFN? I have some experience in Unity but I feel lost in here lol. I’m trying to make a simple aim trainer but can’t figure out how to add scripts to my objects, thank you again for any direction :slight_smile:
