I want to make a little message pop up when I get close to my door where it says to press a button to open door but I have no idea how to make the message.
For the first option you will have to add a text render which you hide by default and set visible as soon as someone enters that trigger box (inside the components view it’s just “box”).
The second one is a bit simpler as you just need to ad the “Draw Text” node into your HUD blueprint however you need to trigger it somehow (I’d suggest a custom event).
