I know this is a little early but I am thinking more and more about the GUI system and features and what it could do in the future..
I have been looking at making my own HUD and what will people be wanting help on and I came up with these.
1st.
I have played with creating an inventory system and got pretty stuck when trying to get the gui to change a texture from lua, what I was trying to do was have a gun change or pick up a grenade and it show in the inventory and HUD, well the inventory code worked the table was populated but I got stuck on two things really dragging from the inventory (with place holder images) to a use bar (in hand bar) and displaying different textures, my idea was to get it working then push it to a demo scene at the time.
2nd.
Render to texture, I know its not a feature yet but it is planned as discussed when I uploaded the plasma tv model to the asset store, then I got thinking how cool would it be to do a demo scene of a mini map.
Attaching a 2D fixed camera looking down on the player and having the camera transmit what it captures to a portion of the HUD with plus and minus signs to zoom in (control how far the camera is above the player).
These two above are where I am at these days with the GUI system, I have kinda just left it where it stands above and moved onto other areas...
