Put the maximum amount of rockets that can be caried in the description, and
also adjust the amount of rocket pods one has when buying a secondary weapon.
The laser and charge beam will remove all rocket capacity. To soften the blow,
you get at least capacity for 5 rockets when buying homing missile systems,
or 10 when buying normal missile system.
Before, if a value was over one of the limits, it would be set to the
other limit. For most usecases, that was fine, however for the starfield
this would cause stars to become aligned to each other after a while.
Some images are made from scratch, others are taken from various sources
with CC0, CC-BY, CC-BY-SA and GPL licenses, mostly from OpenGameArt.org
and NASA.
All functions and variables are now defined in graphics.cpp.
Before, the functions would be compiled again and again for every source
file, now it is compiled only once, halving the size of the stripped
starfighter binary.
There is no reason to have objects which contain only static functions
and no variables. These functions have been moved to the global
namespace and are now defined in .cpp files. The math functions are very
small and have been put in math.h and made static inline.
The state of these options was not only stored in the global config
file, but also in each saved game. When loading a game or clicking on
"continue game" from the title screen, the state of these options would
also be loaded from the save game file. If this changed the state of
sound and music, this would only take effect when starting a mission or
going back to the title screen. If it changed the state of the
fullscreen option, it would never toggle the state, but would
desynchronise the actual state of the window and the fullscreen option.
This is now fixed by moving these options from the currentGame variable
to the engine variable, where they are not in danger of being
overwritten.
Most .h files were not used to declare the externally visible variables
and functions of the .cpp files, but only to #include things and declare
things that were needed by that .cpp file itself. This resulted in a lot
of duplication.
Now the .h files only declare what is externally visible from the
corresponding .cpp files. Starfighter.h includes all the other .h files,
and all .cpp files only #include "Starfighter.h". Functions and
variables that were not used outside the .cpp file that contained them
were marked static. Variables defined in .h files were moved to the
appropriate .cpp files.
This fixes a bug where one could get more than half the item price back. In
particularly, a level 2 Plasma Cooling Booster would sell for more than you
bought it for.
This fixes Debian bug #253380.
During the game, a lot of images were blitted outside the visible area. Also,
addBuffer() was called even when the destination surface was not the screen,
resulting in unnecessary blits in unBuffer().
This increases efficiency significantly. Before, callgrind estimated that 58%
of the CPU time was spent in doInfo(), taking roughly 1.6 kcycles on average
per call. After, only 0.13 kcycles on average per call are used (12x speedup),
and only 14% of the CPU time is spent in doInfo().
Scrolling 1/4 pixel per frame results in jerky motion, mostly because 4
times 16 2/3 milliseconds is not a round number. Scrolling 1/3 pixel per
frame results in much smoother scrolling.
