After testing with a savegame on ZDCMP2 which is probably the largest map in existence, timing both methods resulted in a speed difference of less than 40 ms (70 vs 110 ms for reading all sectory, linedefs, sidedefs and objects).
This compares to an overall restoration time, including reloading the level, precaching all textures and setting everything up, of approx. 1.2 s, meaning an increase of 3% of the entire reloading time.
That's simply not worth all the negative side effects that may happen with a method that highly depends on proper code construction.
On the other hand, using random access means that a savegame version change is only needed now when the semantics of a field change, but not if some get added or deleted.
- do not I_Error out in the serializer unless caused by a programming error.
It is better to let the serializer finish, collect all the errors and I_Error out when the game is known to be in a stable enough state to allow unwinding.
It turned out this may not be done automatically when opening the savegame - it has to be done later, after the pre-spawned map thinkers and all connected objects have been destroyed.
The object deserializer also has to be rather careful about dealing with parse errors, because if something goes wrong a whole batch of uninitialized or partially initialized objects will be left behind to destroy.
This means that no object class may assume that anything but the default constructor has been run on it and needs to check any variable it may reference.
- fixed a few errors in the ACS module serializer.
- reordered a few things to how they were in the old code.
- optimized serialization of the level.Scrolls array to happen within the sector. This is to allow skipping 0-entries which normally constitute the vast majority of them.
The way this was done was a major headache inducer, requiring reconstruction of the function each time the value was changed and in general made actor damage a major hassle.
There was a DECORATE wrapper to mimic the original behavior but this looked quite broken because it completely ignored the different semantics of both damage calculation types.
It also made it impossible to determine if damage was a function or a value.
This accessor has been reverted to what it should be, only returning the constant, which now is -1 for a damage function. I am sorry if this may break the odd mod out but a quick look over some DECORATE-heavy stuff showed that this was never combined in any of them so that accessing 'damage' in DECORATE code depended on an actual damage function.
To get proper damage, a future commit will add a DECORATE function which calls AActor::GetMissileDamage.
int SetActorFlag(int tid, str flagname, bool value);
- Mimics DECORATE's A_ChangeFlag
- Returns number of actors affected (number of things with the flag)
- Affects activator if TID is 0
# Conflicts:
# src/p_acs.cpp
It acts as a simple wrapper around P_DamageMobj which can damage a
single actor, but can also set the actor inflicting the damage. It
returns the amount of damage actually done, or -1 if the damaging was
cancelled.
bool CheckActorState(int tid, str statename, bool exact = false);
- Same parameter order as SetActorState
- Returns true if actor has the state; else returns false
SPF_NOTIMEFREEZE processes particles with this flag regardless of time freeze. The endsize parameter changes the scale of the particle to that size throughout its lifetime linearly.
- If the two strings compared both point to the same location in memory,
then we know they are the same string without having to bother actually
comparing their contents. Note that the opposite is not neccessarily
true: If they point to two different locations, they could still match a
case-sensitive comparison because there are still two ACS string tables:
the one that belongs to the map's script and the one that belongs to
everything else.
In some places, P_UndoPlayerMorph was called with the 'force' argument placed in the 'unmorphflag' parameter, so that 'forced' unmorphs would be not completely forceful.
I hope no mod relied on this weirdness...
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.
