In this demo scene you walk into a trigger that displays a GUI giving information to the player, this is useful for gaining intel, telling a story etc etc.
I will update later on with the FPS version as you have to disable the HUD to be able to click any buttons on the GUI.
If your in FPS player supplied with skyline when you hit the trigger it displays the GUI fine but but the FPS HUD covers the button so you have to disable the HUD while the GUI is active. I have this working but still need to do some work on it.
In 3rd person mode you need to change the TAG to "Player" for it to work, again you get the following error when you click exit on the GUI.
