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 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
Various 'subtypes' of an Object exist as poetic licence when describing the script command.
In General where a subtype is listed (rather than an 'Object' type) it means the command can/ should/ or is more normally associated with, that SUB type.
