This reinstates the old FActorInfo as part of the meta data a class can have so that the class descriptor itself can be freed from any data not directly relevant for managing the class's type information.
Both files can now be included independently without causing problems.
This also required moving some inline functions into separate files and splitting off the GC definitions from dobject.h to ensure that r_defs does not need to pull in any part of the object hierarchy.
This addresses the main issue with TObjPtr, namely that using it required pulling in the entire class hierarchy in basic headers like r_defs which polluted nearly every single source file in the project.
- use an enum type for ItemFlags, just like it was done for actor flags. Since the flag word is almost full it may soon be necessary to add a second one and then this kind of security check may become necessary.
1) When used in a hub, returning to a previous level in the hub deactivated the runes if they were a permanent powerup.
2) When picking up two different runes with the same effect, one rune wearing off removed the effect completely.
3) This entire system was done through an extremely hacky CheatFlags implementation. This was a gross hack, and it was no wonder it didn't always work properly.
Like the symbols and the VM functions this is data that is static from startup until shutdown and has no need to be subjected to garbage collection. All things combined this reduces the amount of GC-sensitive objects at startup from 9600 to 600.
Now all actors have the same metaclass and therefore it will always be the same size which will finally allow some needed changes to the type system which couldn't be done because it was occasionally necessary to replace tentatively created classes due to size mismatches.
The goal is to get rid of PClassPlayerPawn and PClassInventory so that the old assumption that all actor class descriptors have the same size can be restored
This is important to remove some code that seriously blocks optimization of the type table because that can only be done if types do not need to be replaced.
* completely scriptified DehackedPickup and FakeInventory.
* scriptified all remaining virtual functions of Inventory, so that its inheritance is now 100% script-side.
* scriptified CallTryPickup and most of the code called by that.
- fixed: Passing local variables by reference did not work in the VM.
- fixed: ClearInventory did not process depleted items properly.
- changed HexenArmor from UNDROPPABLE to UNTOSSABLE because this allowed to remove some special handling in ClearInventory. The only other place which checks this flag also checks UNTOSSABLE.
- replaced Key.KeyNumber with special1. This is only for internal bookkeeping purposes so there's really no need to complicate this with a new variable when this one works just as well.
- ensure that actor defaults contain a valid virtual table and class pointer so that they can actually use virtual and class-dependent method functions. This is needed for retrieving script variables from them.
- added some helpers to set scripted member variables through the native property parser.
Unfortunately some classes, e.g. PowerMorph, MorphProjectile and the powerup contain some that cannot be handled through the 'property' definition on the script side so they need to be done from the native side.
- improved the class pointer to string cast to print the actual type it describes and not the class pointer's own type.
- fixed: The 'is' operator created non-working code when checking the inheritance of a class pointer, it only worked for objects.
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.
