6599e2c425 - moved the VM types into their own file and only include it where really needed. 2017-04-13 01:12:04 +02:00

fc9e304189 - separated class descriptors from VM types.
Combining these two groups of data has been the cause of many hard to detect errors because it allowed liberal casting between types that are used for completely different things.

6308251084 - added a FindSymbol wrapper to PClass so that other code does not need to access the symbol table directly.
- added an isActor utility function to codegen.cpp to simplify a few constructs.

9c9b2ccf6d - replaced more dyn_casts and checks for RUNTIME_CLASS(PClassActor)
It is preferable to use IsDescendantOf wherever possible if we ever want to be able to separate PClass from PType.

e4d2380775 - moved all remaining fields from PClassActor to FActorInfo.
- added a few access functions for FActorInfo variables.

With PClassActor now empty the class descriptors can finally be converted back to static data outside the class hierarchy, like they were before the scripting merge, and untangle the game data from VM internals.

854053a14f - use TArrays instead of TMaps to store damage factors and pain chances.
For these fields maps have no advantage. Linearly searching a small array with up to 10 entries is nearly always faster than generating a hash for finding the entry in the map.

4afe2d4218 - moved OwnedStates and NumOwnedStates out of PClassActor. 2017-04-11 22:44:35 +02:00
Christoph Oelckers
311ce2362a - started moving stuff out of PClassActor into meta data.
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.

e551ef52f8 - removed atag parameter from GetConstantAddress. 2017-04-10 15:39:04 +02:00
Christoph Oelckers
ef77cbd295 - stop using the ATAGs for checking pointer types in asserts.
This is an incredibly costly way to do a debug check as it infests the entire VM design from top to bottom. These tags are basically useless for anything else but validating object pointers being passed to native functions (i.e. mismatches between definition and declaration) and that simply does not justify a feature that costs execution time in non-debug builds and added memory overhead everywhere.
Note that this commit does not remove the tags, it only discontinues their use.

dd30d2a045 DEHACKED lumps from IWAD now have precedence over embedded lumps and separate files
See https://forum.drdteam.org/viewtopic.php?t=7588

Processing order is now the same as in Chocolate Doom
prBoom+ loads separate files after all WAD lumps though
This makes sense but would change loading sequence existed in ZDoom for years

9ef88ea327 - need to be careful with ctype functions - the way they are written they will do bad things with non-ASCII characters if signed chars are fed to them. 2017-03-18 19:37:36 +01:00

9a10a0f136 Added handling of any space characters in BEX par times
Back to Saturn X E1: Get Out Of My Stations (https://www.doomworld.com/idgames/levels/doom2/megawads/btsx_e1) uses tabs instead of spaces and bunch of 'Need data after par' warnings were printed during loading
PrBoom supports arbitrary space characters too

cd392e50e9 - added a dummy struct named '_' to define global variables. This can only be used internally.
This method was chosen because it avoids adding variable declarations to the global namespace which would have required a lot more work while polluting the grammar.
This way the global variables can be handled by a small bit of special coding in the struct generator.

8277299135 - Turned DropItem into a plain struct again like it was before the scripting branch got merged.
Making this an object had little to no advantage, except being able to remove the deleter code. Now, with some of the class data already being allocated in a memory arena so that freeing it is easier, this can also be used for the drop item lists which makes it unnecessary to subject them to the GC. This also merges the memory arenas for VM functions and flat pointers because both get deleted at the same time so they can share the same one.

c77f6636f8 - moved the three remaining variables from PClassInventory to PClassActor so that PClassInventory can be removed. 2017-02-08 18:11:23 +01:00

a6785afddb - optimized the FName versions of IsDescendantOf and IsKindOf. These can be done without first looking up the class type itself. 2017-02-08 15:47:22 +01:00

5a81a4ca16 - moved a few things around to have them into better fitting places. 2017-02-08 12:24:08 +01:00

6d28aa3541 - do not use strtol for parsing critical values that can get large.
This function will truncate everything that is larger than LONG_MAX or smaller than LONG_MIN to fit into a long variable, but longs are 32 bit on Windows and 64 bit elsewhere, so to ensure consistency and the ability to parse larger values better use strtoll which does not truncate 32 bit values.

4fa5055548 - fixed: With some functions moved to Weapon, Dehacked needs to check Weapon, not StateProvider to find its code pointers. 2017-01-20 17:23:13 +01:00

3c30b59bab more inventory scriptification
* 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.

8256f25a84 - no need to keep AArmor native, now that all child classes have been scriptified. 2017-01-18 23:46:19 +01:00

Christoph Oelckers
30a8541a15 - scriptified the weapon piece functions.
- 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.

Christoph Oelckers
534b2ebbfb - scriptified the remains of APowerup.
- 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.

Christoph Oelckers
14f2c39e58 - scriptified cht_Give and cht_Take and made them virtual function of PlayerPawn so that this can be better configured for mods that want other options in here.
- 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.

03c7b10fd6 - fully scriptified HealthPickup. 2017-01-15 18:46:40 +01:00
Christoph Oelckers
179b6e1a39 - added property definitions to the ZScript parser. This will allow defining custom properties for the default block in custom base classes. See 'Health' for an example.
- support transient object member variables for information that does not need to be put in a savegame.
- fixed: special initialization of objects needs to pass the proper defaults along, otherwise the parent classes will use their own, inappropriate one.

7b7623d2c4 - split DObject::Destroy into the main method, a native OnDestroy and a scripted OnDestroy method and made the main method non-virtual
This was done to ensure it can be properly overridden in scripts without causing problems when called during engine shutdown for the type and symbol objects the VM needs to work and to have the scripted version always run first.
Since the scripted OnDestroy method never calls the native version - the native one is run after the scripted one - this can be simply skipped over during shutdown.

23482735a0 - removed PClassAmmo.
No need to maintain these clunky meta class for one single property. The overhead the mere existence of this class creates is far more than 100 spawned ammo items would cost.
There is no need to serialize AAmmo::DropAmount, this value has no meaning on an already spawned item.

86544086df - allow the VM to run on one global stack per thread.
It is utterly pointless to require every function that wants to make a VM call to allocate a new stack first. The allocation overhead doubles the time to set up the call.
With one stack, previously allocated memory can be reused. The only important thing is, if this ever gets used in a multithreaded environment to have the stack being declared as thread_local, although for ZDoom this is of no consequence.

- eliminated all cases where native code was calling other native code through the VM interface. After scriptifying the game code, only 5 places were left which were quickly eliminated. This was mostly to ensure that the native VM function parameters do not need to be propagated further than absolutely necessary.

8a50004f55 - cleanup of the virtual function definitions for inventory items. Let's better use 'virtual' and 'override' everywhere to make sure that nothing gets overlooked.
- added call wrappers and script hooks for all relevant virtuals in AInventory.
- made GetSpeedFactor and GetNoTeleportFreeze entirely scripted because they are too trivial - also do them iteratively, just like HandlePickup, because it's just a better way to do this stuff.

b0f3121bec - split up zscript/shared/inventory.txt.
- moved health items to their own file.
- scriptified ScoreItem and MapRevealer whose entire functionality was a small TryPickup method.
- fixed: bit fields in global variables were not correctly written.

This should conclude the inventory cleanup. It is now possible again to find things in there.

78fa076079 - moved armor class declarations to their own file and added necessary #includes only to those files actually using them.

d2ce78fae7 - changed the return value of PickupMessage to an FString so that it can interface with scripts.

82e5e2daa9 - fixed a variable mixup in Dehacked weapon initialization.
This ultimately failed to set the weapon's AmmoUse field and made the weapon fail to detect it's out of ammo.

11ac0c622b - fixed: The BFG needs to get its default ammo usage from the DehInfo struct.
- fixed: State's fields need to be declared native.
