CifFile/CifTree classes have been completely rewritten and
moved to their own header file. ResourceManager is now
exclusively responsible for loading IFF files, making sure
loose .iff/.cif files take precedence before ones embedded
in a ciftree.
Also, completed work on the cif/ciftree exporting functions.
It seems the kSceneCount dependency type has been
broken pretty much always, and the last attempt at fixing it
was a fluke. Also added checks for nancy7, since the devs
decided that, for whatever reason, the conditions need to
be flipped, and what was before a less-than check is now a
greater-than one, and vice versa.
Previously, the NancyEngine class was responsible for
handling creation and destruction of many naked pointers
to engine data, which led to several instances of memory
leaks that needed to be fixed. These changes introduce a
standard way of handling that same data, similar to the
one already used by PuzzleData inside Scene. Unfortunately,
this does add the need for relevant data to be casted to
the proper type before it is handled.
Added support for 3D sound, as introduced in nancy3.
The original engine used DirectSound 3D, which enabled
for easy sound panning, attenuation based on distance,
and doppler effect simulation. The DS3D algorithm
has only been approximated; in particular, there are some
minor differences when it comes to sound panning.
nancy3 changed the way the kKeepAlways inventory flag
worked, and added a third flag with the old behavior. As
a result of this change, the suitcase key in nancy3 no longer
disappears after being used.
Added missing dependency types to the list_actionrecords
console command, and made sure it respects the recursive
nature of dependencies in nancy3 and above. Fixed a crash
due to the event flag numbering being changed in nancy3.
Fixed a typo in the function name.
Items marked as single-use are now correctly removed from
the inventory. Also extended the get_inventory console
command to show if an item is single-use or not.
Nancy3 did away with earlier versions of the engine's usage
of 1 and 2 as false/true values. This commit adds two
new values to NancyEngine: _true and _false, which hold
the correct values used by different versions of the engine.
Nancy3 introduced the kOpenParenthesis and
kCloseParenthesis dependency types, which allow for
more complicated dependency logic. This commit changes
the structure of the DependencyRecord type to support
parent-child relationships similar to the ones found
inside the original implementation's code. Also introduced
is the static canHaveHotspot() function in ActionRecord,
which is used to correctly implement cursor dependencies.
Replaced the hexadecimal ActionRecord typeIDs and replaced
them with the ones found inside gameflow.h. Also updated
the scan_ar_type console command to match.
The resource manager now keeps track of its cif trees and calls to loadImage() and loadData() don't need to specify a cif tree. In order to support The Vampire Diaries, IFFs can now be loaded from their own dedicated .iff file, and the engine doesn't require a cif tree to be loaded on boot.
Made all states (Scene, Credits, Help, etc.) singletons, as well as subclasses of a common State parent with a proper state switching API. Moved the OnPause virtual function from RenderObject to ActionRecord and hooked it into the state switching code. Also got rid of the NancyEngine pointer that got passed around between most classes, and replaced it with several convenience macros. As a result of these changes action records that render to the viewport no longer disappear after opening the menu, and state changes feel snappier.
Added initial support for savestates. The format will most likely change with future commits, but I will only start versioning once the engine supports more than a single game. To support proper serialization the Scene state has had its kInit state split into kInit and kInitStatic, InventoryBox had some of its code reordered, and members of several classes have had their types changed.
Renamed all functions relating to the engine's internal state so they only mention the word State instead of GameState. This is to avoid confusion between them and functions relating to savegames, whose names already include GameState.
The original engine stores sound information in at least four different types of structs, all of which can now be loaded and played back. Also implemented sound types, which will be configurable from the ScummVM interface, added the correct number of sound channels, and implemented sound fx in a couple of action record types.
