Object
Object refers to a building block within a scenario. In general when using this term the author refers to the representation of an object (soldier, house, crate, etc) that can be manipulated when in the 3D environment via the scripting language. As there is a special representation that is used in the mission editor, one might distinguish between a 'game object' (this article) and an 'editor object' (see Editor Object).
Object Type
An Object in the scripting language is a generic reference for a soldier, vehicle or building. Such an object can be animated (a house, a tank), can have ai associated with it (a soldier), or, simply be a 'Rock'. Various commands in the scripting language can refer as equally to generic (eg Object) types, as much as specific subtypes.
_pos = getPos player; _pos = getPos _MyHouse;
Subtypes
In this wiki, when describing commands, various 'subtypes' of an object are distinguished. Although in general the commands accept parameters of type 'object', when a subtype is listed, the use of subtypes indicates that the command might not make sense or might not work on all objects.
