57de598e48 Added implicit scope for if/else, while and do/while statements in ZScript
Scope is added only for variable or constant definition so it will no longer leak to outer scope

57d703236b - changed Doom source license to GPL in all subdirectories and fixed missing licenses in a few other files. 2017-04-17 12:27:19 +02:00

cd180d29c7 - block direct use of 'new' for DObjects.
This is to ensure that the Class pointer can be set right on creation. ZDoom had always depended on handling this lazily which poses some problems for the VM.
So now there is a variadic Create<classtype> function taking care of that, but to ensure that it gets used, direct access to the new operator has been blocked.

This also neccessitated making DArgs a regular object because they get created before the type system is up. Since the few uses of DArgs are easily controllable this wasn't a big issue.

- did a bit of optimization on the bots' decision making whether to pick up a health item or not.

98dab9c4b9 - took PTypeBase and all its subclasses out of the DObject hierarchy.
- moved scope flag to a new variable that is specific to PType instead of hijacking the ObjectFlags for this.

b2d944974e - first stage of simplifying the type system.
Let's use inline checkers in PType instead of constantly having to do clumsy IsKindOf checks etc. Once complete this also means that the types can be taken out of the class hierarchy, freeing up some common names.

85d8244d03 - fixed: With the reorganization of the class data the setup of actor replacements must be delayed until after InitializeDefaults has been called. 2017-04-13 02:18:06 +02:00

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.

96631e8808 - make PClass not inherit from PStruct.
Having these two types related can cause problems with detection in the compiler because for some parts they need quite different handling.
Common handling for the fields has been moved into PSymbolTable but overall redundancy was quite minor as both types share surprisingly little functionality.

0d7b7d6ab1 - merged PStruct and PNativeStruct.
There were exactly 4 places in the code that checked for the difference, this is better done with a flag.

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.

5350721ec5 - removed PClass::DeriveData because it is no longer needed.
- fixed: IsVisibleToPlayer and optimized it a bit more.
- moved SourceLumpName to PClass, so that it can also be used for non-actors (there's a lot of non-Actor classes already.)
- separated the serializer for PClassPointer from PPointer. Even though not doable, a pointer to a class type is something entirely different than a class pointer with a restriction so each should handle its own case.

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.

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.

a3ee3c287e - major progress on the status bar code: SBARINFO's DrawGraphic has been ported into a generic function of the base statusbar class and put to use for a few items on the Strife status bar.
- decided to ditch the widget system I had started to lay out. As it turns out that would make things far more complicated and slower than they need to be.

4417afd548 - changed VMValue to handle strings by reference.
This makes VMValue a real POD type with no hacky overloads and eliminates a lot of destructor code in all places that call a VM function. Due to the way this had to be handled, none of these destructors could be skipped because any value could have been a string.
This required some minor changes in functions that passed a temporary FString into the VM to ensure that the temporary object lives long enough to be handled. The code generator had already been changed to deal with this in a previous commit.
This is easily offset by the code savings and reduced maintenance needs elsewhere.

9bffe4ee50 - scriptified the main statusbar interface and the Strife status bar.
Note that the Strife status bar does not draw the health bars yet. I tried to replace the hacky custom texture with a single fill operation but had to find out that all the coordinate mangling for the status bar is being done deep in the video code. This needs to be fixed before this can be made to work.

Currently this is not usable in mods because they cannot initialize custom status bars yet.

Christoph Oelckers
6926875b21 - allow parsing of static constant arrays in class scope.
This is only the parsing part, the arrays are not yet getting evaluated.
This required quite a hacky workaround because the gramma couldn't be made to accept the rule. The scanner will check if a 'static' token is immediately followed by a 'const' token and will combine both to a new 'staticconst' token that does not create conflicts with other rules.

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.

5fd86cf98c - added some syntactic help to the ZScript parser to allow defining the arrays with native structs on the script side instead of having to define them internally. 2017-03-13 12:51:09 +01:00

77bac4f6fa - fixed code generation for min/max when the first operand was a local variable or constant.
The code for constants was not optimal because the first operand of the instructions cannot be constant. This was solved by swapping it with the second choice which will always be non-constant.
The code for local variables did not allocate a new destination register and would overwrite the first parameter's variable.

456ac64723 - implemented version checks for compile-time type determination and for class inheritance.
Note that in this system, DECORATE counts as version 2.0, so any data that should be available to DECORATE should not use version restriction.

7df698dad8 - implemented the parser basics of a ZScript versioning system.
Note that this completely disables the newly added keywords 'play' and 'ui' for unversioned code to allow using them as identifiers as I have found at least one mod that uses a variable named 'play' that would have been rendered broken otherwise.
This also disables many ZScript only keywords for other parsing jobs.
