Unlike the other classes, the places where variables from this class were accessed were quite scattered so there isn't much scriptified code. Instead, most of these places are now using the script variable access methods.
This was the last remaining subclass of AActor, meaning that class Actor can now be opened for user-side extensions.
Changed to use 32 bit and also fixed the random number call which was using the byte value variant of the access operator, effectively limiting the number of choices to 256.
This revealed an interesting bug: When the berserk fadout formula was changed in 2005 the result was essentially broken, resulting in values around 7000 - it only worked by happenstance because the lower 8 bits of the resulting values just happened to work to some degree and never overflowed. But the resulting fade was far too weak and a slightly different handling of the color composition code for the VM made it break down entirely.
This restores the pre-2005 formula but weakened intensity which now comes a lot closer to how it is supposed to look.
The entire setup was quite broken with each item using its own activation result and the ones of the subsequent items in the list as the return value.
This rendered the STANDSTILL check in the main function totally unpredictable because the value it depended on could come from any item in the list.
Changed it so that the main dispatcher function is part of sector_t and does the stepping through the list iteratively instead of letting each item recursively call its successor and let this function decide for each item alone whether it should be removed.
The broken setup also had the effect that any MusicChanger would trigger all following SecActEnter specials right on msp start.
This can be done with a lot less overhead by using one of the object's properties to store the activation flag, so that all the nearly redundant trigger methods can be folded into one.
Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going.
It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes
- allow recursive linking of $random definitions (as long as they do not link back, see above.)
- fixed the sound precaching which did not handle $alias inside $random. Normally this went undetected but in cases where the random sound index was the same as a sound index in the current link chain this could hang the function.
The only reason this even existed was that ZDoom's original VC projects used __fastcall. The CMake generated project do not, they stick to __cdecl.
Since no performance gain can be seen by using __fastcall the best course of action is to just remove all traces of it from the source and forget that it ever existed.
* OPL: specify the core to use for playing this song
* FluidSynth: specify a soundfont that should be used for playing the song.
* WildMidi: specify a config file that should be used for playing the song.
* Timidity++: specify an executable that should be used for playing the song. At least under Windows this allows using Timidity++ with different configs if the executable and each single config are placed in different directories.
* GUS: currently not operational, but should later also specify the config. This will need some work, because right now this is initialized only when the sound system is initialized.
* all other: no function.
These options should mainly be for end users who want to fine-tune how to play the music.
- Move MUSINFO change request out of FLevelLocals and into player_t. This
allows the MusicChanger actors to change music for each player
independantly. This is similar to PrBoom+, which switches depending on
the displayplayer. The difference being, we don't actually track the
music other players are listening to. (Which might not be a bad idea to
implement at some point.)
- Moved a few fields in player_t for better packing.
