When the player character (which has a selector) is near to a usable NPC, a text appears. Also, when you are not in range, it disappears. That's cool, and it is a great way of letting the player know if he can interact with the specific NPC.
However, I prefer to show it through a little icon. I have tested the reticle option which does the exact thing I want to implement. However, the icon is always in the centre, and I don't know if there is a way to move it a little bit to the left/right/up/down or it is always static.
Any idea? Other ways are also welcome

Thanks!

Regards!
