Added basic data types
This page details the technical '''inner workings of ManiaPlanet''' (and the original TrackMania). It describes the game's classes, data structures and functions, and is as such geared towards reverse engineers and programmers.

VirtualParam_Get() and VirtualParam_Set() should not be used directly. These only exist for handling calculated properties (where the value doesn't come directly from a field in the class but is calculated). Instead, use the nonvirtual wrapper methods GetProperty() and CallMethod() which handle both field properties and calculated properties.

A .gbx file contains a serialized main object instance whose type is indicated by classID. This main object can reference other objects, which may be contained in the same .gbx file or in other files.
A .gbx file contains a serialized main object instance whose type is indicated by classID. This main object can reference other objects, which may be contained in the same .gbx file or in other files.
All objects, both from the current .gbx file and from external files, are stored in the nodEntries list. The main object of the .gbx file is always at index 0. Every time a subobject is read from the .gbx file, or an external file is referenced, the nodEntries index is specified where the object should be stored. The process of reading .gbx files is explained in detail on the [[GBX|GBX page]].
All objects, both from the current .gbx file and from external files, are stored in the nodEntries list. The main object of the .gbx file is always at index 0. Every time a subobject is read from the .gbx file, or an external file is referenced, the nodEntries index is specified where the object should be stored.
The process for reading a complete *.gbx file looks like this:
LoadFileFrom -> DoLoadFile -> DoFidLoadFile -> DoLoadAll -> { DoLoadHeader { -> LoadCurrentHeader } -> DoLoadRef -> DoLoadBody }
Reading the file header and body is explained in detail on the [[GBX|GBX page]].
