=== Possible Enhancements === | |||
Present in the original game | * Add sound support for sound cards other than Adlib, such as Roland | ||
* Rewrite the savegame mechanism | |||
Currently the savegame code works similiar to the original, in that every object derives from a 'SavedObject' base, which is registered in a master list when objects that derive from it are instantiated. So the saving code essentially loops through the objects one by one to have each save their data in turn. The trouble with this it when loading a savegame, it relies on all the objects registered in the list to have been instantiated in the exact same order; which may not be the case if the savegame is loaded in another system, or even which an executable compiled using another compiler, since the fields of a given class are guaranteed to be created in the same order. | |||
A lot of this could be resolved by replacing this with a manual hierarchnical saving of data, where the overall Globals object would explicitly call the synchronize method of all the objects within it, and they each explicitly call the method for the objects they contain, and so on. Whilst this would handle the majority of the save process, there is one remaining issue, that of pointer handling. | |||
In many places in the engine there are pointers to other objects. The Sequence (Cutscene) manager can, for example, take in pointers for the characters the cutscene applies to. Currently these are handled by storing the index in the list of instantiated objects of the object the pointer points to, and then doing a lookup doing savegame restore. Because of this, it will be very difficult to get rid of the existing savegame mechanism without coming up with a good way to represent the same information. Perhaps giving any object that can be pointed to a unique Id, and having a lookup list of only those Ids. This might ensure savegame restore would work, and allow them to be portable. | |||
