When rendering directly to the output buffer, we need to maintain the
state of what has been drawn and what needs redrawing per-buffer.
We previously tried to do it implicitly by checking `SDL_DOUBLEBUF` and
other flags. The previous implementation was broken in several
ways, resulting in rendering issues on devices that support 8-bit output
directly.
Changes this mechanism to explicitly maintain buffer state per output
buffer. The new mechanism doesn't require knowledge of the number of
buffers, and thus also works correctly with triple-buffering.
Fixes#5447
Adds a custom sized type for the world tile rectagle.
This allows us to better express intent.
It also allows us to make certain globals smaller, e.g. `THEME_LOC`.
https://github.com/diasurgical/devilutionx-mpq-tools produces an unpacked MPQ
with all the graphics converted to CLX and the unused files removed.
This is primarily useful on RAM-constrained platforms, such as PS2,
because it eliminates the MPQ overhead.
Adds a build option to load from such unpacked directories instead of the MPQ.
These directories are searched for in the same locations
where the MPQs would be searched for otherwise.
Example directory layout:
* /usr/local/share/diasurgical/devilutionx/diabdat/ -- unpacked and converted diabdat.mpq
* /usr/local/share/diasurgical/devilutionx/hellfire/ -- unpacked and converted hellfire MPQs (all of them merged into 1 directory)
* /usr/local/share/diasurgical/devilutionx/fonts/ -- unpacked fonts.mpq
* /usr/local/share/diasurgical/devilutionx/pl/ -- unpacked pl.mpq
These directory structure is produced by calling `unpack_and_minify_mpq`
We want to be able to use unpacked MPQs on low-end platforms
(PS2/rg99/etc).
This is tricky on case-sensitive filesystems. Avoids case issues by
lowercasing all paths in the code (then we'll just need lowercased
listfiles).
* Synchronize item placement in player's backpack
* Synchronize item remove from player's backpack
* Synchronize item placement and removal from player's belt
* Set up loopback network provider for failing tests
IsPlayerAdjacentToObject() is checked before calling OperateObject().
Previously teleFlag would ignore sendmsg which was likely a bug causing
the event to fire multiple times.
The format is almost identical to CL2, except it uses the frame header
to store frame width and height instead of 5 32-line offsets.
This means we always have access to frame dimensions, so we can use it
as an on-disk format for our graphics as well.
Additionally, we may be able to optimize the rendering even more
in the future now that we have guaranteed knowledge of frame dimensions.
