The vsync delay is 14 ms (1000 / 70), and using a loop with
a sleep of 10ms until we had passed that delay meant we were
actually waiting anytime between 14 and 23 milliseconds, which
made the game slower than it should be. This was partially
corrected by using a delay of 11 ms (800 / 70), but this was
still inacurate and too slow in average.
In addition, since the change in commit 87c8b60, it was ignoring
the time spent in the game loop, which on slow devices is not
negligeable, and this has been fixed as well.
Finally also change the fast speed from 20 to 4. In commit
87c8b60 the delay was changed from macroseconds to milliseconds,
and any speed above 14 would then result in a delay of 0 due to
the integer division. We have the turbo mode for that, so it
seems to make sense to make the fast mode a bit slower rather
than having two modes that do the same thing.
When the Ex memory regions are close to full, it is possible for
the game to fail to purge objects and then crash with an OOM error
even if it isn't actually out of memory. This patch calculates the
amount of free memory truly needed when allocating to Ex memory to
allow exactly the entire frame & text regions to be used, instead
previously where a hard-coded amount of free space to maintain was
used, which guaranteed that the entire memory region could not
actually be used by the game.
This change may be masking some underlying memory leak, or it may
just be that near the end of the game the game naturally comes
close to reaching the maximum memory region size. For the moment,
I am assuming the latter.
This commit also adds some assertion checks to the memory transfer
functions to make sure the regions don't quietly overflow in other
cases, since pickupConts performs transfers in a manner that
doesn't ensure enough free memory exists for them to be successful.
Fixes Trac#6820.
Recently we started to use this as new semantics, although in the past
we used simly <engine>_H. Now these guard defines are consistent with
rest of the files which are used in the engines.
The original interpreter only used english commands in the terminal
even when playing one of the localised version (and even though
everything else in the terminal was localised). This adds the possibility
to either use the English commands or the localised ones.
Localized commands have been added for French, German (thanks to
SimSaw, who also proposed that idea) and Italian (thanks to Maff).
Removed the buffer from being a global non-const variable. Also, the
code changes should allow the buffer size to be increased by just
changing the size of _keyBuffer if needed.
This is possible, since the game is freeware now. It is very
helpful when playing the game in order to avoid referring to the
manual. The extra help text is shown when the player uses the
'help' command inside the game terminal.
Also, the list of games where copy protection is skipped has been
reordered alphabetically in the README
Theoretically, it should be almost as big as _inputLine, so let's
make them the exact same size just for simplicity. This fixes crashes
for me when trying to use very long parameters to the monitor's READ
command, and could possibly fix a bug reported in the German version
where you supposedly have to read "kurzmitteilung".
This change should have no functional change, but makes the sound code
more decoupled, modular and readable, prior to attempting a fix for
bug #3528164 - "DREAMWEB: missing sound effects/music cues during main
title".
This new variable removes the need for duplicates strings of the form
"DREAMWEB.*" spread throughout the dreamweb engine, replacing them with
a common const string on the engine holding the datafile name prefix.
This will reduce binary size and it should also simplify adding support
for foreign language variants, where the datafile name prefix is
changed.
To demostrate usage and prove this, showPCX() is migrated to using this.
