AGS has certain | 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. These include the types: Room, Game, Parser, File, InventoryItem, Overlay, DynamicSprite, GUI, Label, Button, Slider, TextBox, InvWindow, ListBox, Character, GUIControl, Hotspot, Region, Maths, DateTime, and Object. | ||
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.
