b3aa7c61a9 - fixed: Class and struct name lookup was not context aware.
If a later module reused an existing name for a different class or struct type, this new name would completely shadow the old one, even in the base files.
Changed it so that each compilation unit (i.e. each ZScript and DECORATE lump) get their own symbol table and can only see the symbol tables that got defined in lower numbered resource files so that later definitions do not pollute the available list of symbols when running the compiler backend and code generator - which happens after everything has been parsed.

Another effect of this is that a mod that reuses the name of an internal global constant will only see its own constant, again reducing the risk of potential errors in case the internal definitions add some new values.

Global constants are still discouraged from being used because what this does not and can not handle is the case that a mod defines a global constant with the same name as a class variable. In such a case the class variable will always take precedence for code inside that class.

Note that the internal struct String had to be renamed for this because the stricter checks did not let the type String pass on the left side of a '.' anymore.

- made PEnum inherit from PInt and not from PNamedType.

The old inheritance broke nearly every check for integer compatibility in the compiler, so this hopefully leads to a working enum implementation.

6f5fff00a0 Implemented static methods in String struct. Implemented String.Format and String.AppendFormat. Implemented native vararg methods for the future. 2017-01-21 10:32:26 +01:00

c880b26d98 - scriptified MorphProjectile and CustomSprite.
This should for now conclude actor class scriptification. The remaining ten classes with the exception of MorphedMonster are all too essential or too closely tied to engine feature so they should remain native.

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.

c317a4cbf3 - Fixed: wrong FString 'Replace' action function.
The function replaced only the first character of the first argument with the first character of the second argument.

5ef9429ae4 - added the ability to attach a constructor or destructor to an internally defined struct.
There are a few which require explicit native construction or destruction that need to be exported to the VM, e.g. FCheckPosition.
The VM cannot handle this directly, it needs two special functions to be attached to handle such elements.

de4153ceaf some groundwork for the implementation of dynamic arrays
- created script exports for all relevant functions with all integral types.
- created script side definitions for the underlying data types.
- added a void pointer type so that the prototype for the pointer array can use a generic type every pointer can be assigned to.

cd7986b1b1 - refactored global sides array to be more VM friendly.
- moved FLevelLocals to its own header to resolve some circular include conflicts.

71d1138376 - refactored the global lines array into a more VM friendly form, moved it to FLevelLocals and exported it to ZScript.
- disabled the Build map loader after finding out that it has been completely broken and nonfunctional for a long time. Since this has no real value it will probably removed entirely in an upcoming commit.

c02281a439 - refactored the global sectors array into a more VM friendly type and moved it into FLevelLocals. 2017-01-07 19:32:24 +01:00
Christoph Oelckers
1a16f664e4 - added a TStaticArray class that allows safe access to resizable static data (like the sectors, linedefs, etc.) for the VM.
- used this to replace the line list in Sector because that gets already used and implemented proper bounds checks for this type of array.

fbf8084999 - corrected the export signatures of several script exports to contain the correct classes, so that the fudging in FindFunction could be removed.
- fixed PARAM_ACTION_PROLOGUE to assign correct types to the implicit pointers. It gave the actual class to the wrong one, which until now did not matter because all functions were using 'Actor', regardless of actual class association.
- fixed the definition of IceChunk and removed some redundant code here. Since A_FreezeDeathChunks already calls SetState, which in turn calls the state's action function, there is no need to call it again explicitly.

3af9232fca - scriptified a_strifeitems.cpp and a_debris.cpp.
- Changed the glass shards so that they do not have to override FloorBounceMissile. It was the only place where this was virtually overridden and provided little usefulness.
- made 'out' variables work.
- fixed virtual call handling for HandlePickup.

9064a5b0ac - scriptified Strife's coins.
- added a String class to allow attaching methods to the builtin string type. This works by checking if the left side of the member accessor is a string and just replacing the tyoe in this one place, all the rest is automatic.

ebd2c27e0a - scriptified Hexen's Bloodscourge and Serpent.
- merged the FrontBlock searcher for the Bloodscourge into RoughMonsterSearch. This also fixes the bug that the searcher was not initialized properly for the MageBoss.

de6969997a - scriptified Hexen's flies.
A few notes:

 * this accesses the lines array in sector_t which effectively is a pointer to an array of pointers - a type the parser can not represent. The compiler has no problems with it, so for now it is defined internally.
 * array sizes were limited to 65536 entries because the 'bound' instruction only existed as an immediate version with no provisions for larger values. For the static map arrays 65536 is not sufficient so now there are alternative instructions for these cases.
 * despite the above, at the moment there is no proper bounds checking for arrays that have no fixed size. To do this, a lot more work is needed. The type system as-is is not prepared for such a scenario.

177aa6ec42 - converted half of ClericHoly. (Making a commit before starting on the more complex stuff.)
- added a 'constructor' for color values.

7385cd70c0 - scriptified the Minotaur.
Interesting tidbit: The damage calculation in P_MinotaurSlam had been incorrect for the Heretic version since the friendly Hexen Dark Servant was added, but nobody ever noticed in 14 years...

8dba322775 - scriptified Heretic's Skull Rod.
- Took the opportunity and fixed the logic for the Skull Rod's rain spawner. The old code which was part of the 3D floor submission was unable to work with portals at all. The new approach no longer tries to hide the dead projectile in the ceiling, it leaves it where it is and changes a few flags, so that its z-position can be used as reference to get the actual ceiling. This works for line portals, but for sector portals still requires some changes to sector_t::NextHighestCeilingAt to work, but at least this can be made to work unlike the old code.
- added names for the player-related translations to A_SetTranslation.
- fixed: Failure to resolve a function argument was checked for, too late.
- made the parameter for A_SetTranslation a name instead of a string, because it is more efficient. We do not need full strings here.

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

3f5bf88d69 - scriptified Heretic's mace.
- fixed: FxAssignSelf did not the correct number of registers for vector operations.
- fixed a few asserts in vector2 instructions.
- turned the virtual AActor::HitFloor method into a flag MF7_SMASHABLE. The only use of this function was to kill Hexen's pottery when they hit the floor, and this looks like something that can be exposed to modders less clumsily.

46757ff8bf - exported the native fields of FState and FLevelLocals as well. 2016-11-23 00:35:06 +01:00
Christoph Oelckers
099b9970ef - added proper definitions for all exported native fields.
- synthesize native fields for all declared flags, not just for AActor.

Christoph Oelckers
980c986305 - allow defining native fields through scripts. Internally this only requires exporting the address, but not the entire field.
- added new VARF_Transient flag so that the decision whether to serialize a field does not depend solely on its native status. It may actually make a lot of sense to use the auto-serializer for native fields, too, as this would eliminate a lot of maintenance code.
- defined (u)int8/16 as aliases to the byte and short types (Can't we not just get rid of this naming convention already...?)
- exporting the fields of Actor revealed a few name clashes between them and some global types, so Actor.Sector was renamed to CurSector and Actor.Inventory was renamed to Actor.Inv.

135cfcf016 - implemented State as an actual native struct, so that its fields can be accessed from scripts.
- refactored state bitfield members into a flag word because the address of a bitfield cannot be taken, making such variables inaccessible to scripts.
- actually use PNativeStruct for representing native structs defined in a script.

6cc00e79a6 - made all internal struct types NativeStructs so that all variables of their types are made references. 2016-11-21 19:20:27 +01:00
Christoph Oelckers
360436c201 - scriptified the scripted marines.
- fixed symbol name generation for native functions.
- moved PrintableName to VMFunction so that native functions also have this information.

Christoph Oelckers
f11f020b6c - allow functions in structs. This is needed for several internal data types like players, sectors, lines, etc.
- added a new type 'NativeStruct'. This will be used for types that cannot be instantiated, and is also needed to cleanly handle many internal types that only can exist as reference.

df4e9324c9 - added terminators to all flag lists. 2016-11-19 09:24:54 +01:00
Christoph Oelckers
3ce699bf9b - implemented pass-by-reference arguments - so far only for memory based variables.
- changed Dehacked weapon function lookup to check the symbol table instead of directly referencing the VM functions. Once scriptified these pointers will no longer be available.
- removed all special ATAGs from the VM. While well intentioned any pointer tagged with them is basically unusable because it'd trigger asserts all over the place.
- scriptified A_Punch for testing pass-by-reference parameters and stack variables.
2016-11-19 01:23:56 +01:00
Christoph Oelckers
8650d6806e - script export of player_t.
- replaced __alignof with the standard alignof equivalent.
