Save games are implemented in two classes, idSaveGame and idRestoreGame, that implement write/read functions for common types. They're passed in to each entity and object for them to archive themselves. Each class implements save/restore functions for it's own data. When restoring, all the objects are instantiated, then the restore function is called on each, superclass first, then subclasses. Pointers are restored by saving out an object index for each unique object pointer and adding them to a list of objects that are to be saved. Restore instantiates all the objects in the list before calling the Restore function on each object so that the pointers returned are valid. No object's restore function should rely on any other objects being fully instantiated until after the restore process is complete. Post restore fixup should be done by posting events with 0 delay. The savegame header will have the Game Name, Version, Map Name, and Player Persistent Info. Changes in version make savegames incompatible, and the game will start from the beginning of the level with the player's persistent info. Changes to classes that don't need to break compatibility can use the build number as the savegame version. Later versions are responsible for restoring from previous versions by ignoring any unused data and initializing variables that weren't in previous versions with safe information. At the head of the save game is enough information to restore the player to the beginning of the level should the file be unloadable in some way (for example, due to script changes). Note: the caching works only if the compresion is enabled. The caching mechanism works in the following way. On game saving, there are two types of data: 1. Ordinary data (almost all the data) This type of data is pushed into the "cache" buffer. 2. Special data which is now: // ui->WriteToSaveGame( file ) - closed source // gameSoundWorld->WriteToSaveGame( file ) - closed source // WriteBuildNumber() and WriteCodeRevision() - vital, should not be compressed This data is written directly to the file. After all the data has been passed to idSaveGame, FinalizeCache must be called. Depending on the settings it may compress the cache. Then it is finally dumped to idFile. After that the last 4 bytes are written to the file - offset to cache start from the end of file. The final file layout is then: 1. Doom3 header (level info, we cannot change it) 2. Special data (including version numbers) 3. Cache image, maybe compressed (consists of ordinary data) 4. Offset from EOF to cache image (is negative) Restoring works almost the same way, but the cache must be retrieved at the very beginning. The InitializeCache must be called before any ordinary data is read from the file. It uses fseek to get offset to cache image, then reads it, probably decompresses it. Afterwards it fseeks to the file position on the moment of call. Then all the Read* happens which reads ordinary data from cache and special data from file. */ idSaveGame::idSaveGame( idFile *savefile ) { file = savefile; // Put NULL at the start of the list so we can skip over it. objects.Clear();
