When it dont work, normally the GUI settings are wrong , please just email me a screenshot of your GUI settings and i will have a look: firstname.lastname@example.org
If you just want everything loaded into your scene and do everything yourself , there is a code included that do this see "mygame.agc" , this just have a do - sync - loop that only display the GameGuru scene.
You should create your own file just like this and call it something unique like "simon3dgame.agc" , add everything from "mygame.agc" into this file , and call it from "main.agk" ( search for "mygame.agc" , to see where to add it ).
You can now make your game in simon3dgame.agc and only the GameGuru scene will be displayed , everything else is up to you.
It even include this function "AddFpeObject" , that you can use to load a GameGuru .fpe object including all objects/textures/settings ... and everything is setup for you even the shaders is setup depending on the textures used by the object, so it also support PBR. Basically you just call this function and the object is displayed in all its glory.
//Add a new object from a loaded FPE file , use the name of the object "desc = Blue Warehouse" , in this case ObjectName$ should be "Blue Warehouse"
//Returns the objectID. or 0 if it fails. sample:
//newobjectID = AddFpeObject("Blue Warehouse",100,100,100,0,0,0,1.0,1.0,1.0);
//SetObjectColor( newobjectID , 255 , 0 , 0 ,255); // make the new object red.
//Will create a new object at position 100,100,100 using roration 0,0,0 and scale 1.0,1.0,1.0 ( no scale ).
Also checkout "loadlevel("level1")" , this will allow you to load in a new GameGuru level.
Hope this helps , if not just give me a email and i will see if im able to help you out
