AGS has certain ''managed'' types that you can not create an instance (variable declaration) of. All of the variables of managed types are ''managed'' by AGS.

'''''Note that not all of the managed types are meant to have pointers to them. Room, Game, Parser, and Maths do not need pointers (you can't even assign them a value).''''' | |||
However, you can work with these managed types through pointers. You define a pointer by typing the variable type, i.e. GUI, then a space, an asterik (*), and finally the name of the pointer. So, to create a pointer named GUIPointer to point to the GUI object named gMygui, you could type: | However, you can work with these managed types through pointers.
