Each section was store dusing the full image size. Now it only uses the
section size, which should reduce considerably the amout of memory used
for each image.
Also when a section has one or more next section, they were all drawn on
the surface for this section, but then they were drawn again on their own
surface. And while this should not cause any issue, this was really
unnecessary (and prevented optimizing the surface size for each section).
So now this is no longer the case and the surface for a section only
contains this section.
The main change consists in using a separate byte array for the sentence
removal flags, move some functions from the GameManager to the Room class,
and add a few additional functions to manipulate this new array. This
allows to clarify some code related to dialogs.
This change also allows to switch the _shown array back to a bool array.
This required the user to click a mouse button to close the message and
get to the mew state. Now the message is automatically closed before
loading the new state.
We can now press the mouse button to leave the title screen instead
of having to press a key. Since the mouse cursor was visible, not
being able to press the mouse button was strange. Especially as it
was possible to use the mouse button earlier in the title screen.
Also we can now use the mouse button or any key other than escape
during the cutscene to move to the next sentence. And the code is
more reactive to pressing the Escape key (we don't need to wait
for the current annimation to finish) to exit the cutscene.
The sound samples start with a 6 bytes header (including the size of
the sample coded on a little endian 16 bits uint on bytes 2 and 3)
and end with 4 bytes set to null. Those were passed to the raw stream,
which resulted in the audible clicks.
Note that we could use the information from the header to load the
sound samples instead of keeping around an array of offset and size.
The saved game files now start with a header and version which allows
to do some sanity check and will allow to change the format in the
future if needed.
Also the MetaEngine can now be queried for the meta infos of a save
state.
GameManager::airless() determined if the space suit could be taken off
by comparing the current room pointer to the allocated room objects.
This led to indeterministic behavior as sometimes airless() would
falsely return true as the dynamic allocation of the Room objects cannot
be expected to be in a certain order.
Implementing the corresponing RoomID to a Room objects solves this
problem.
The original game's time was stored in 55ms ticks but we just run on
milliseconds. setAnimationTimer() sets the ticks the currrent room's
animation() function will not be called.
