5dc94a10c3 Added A_SetInventory.
- Sets the absolute amount of an inventory actor.
- Limits itself to the range [0, MaxAmount]. Setting beyondMax to true disregards the MaxAmount. Default is false.

d8c689d874 - initialize function symbols. At the moment all it does is process the existing native functions. Any further processing will be done once the base classes of the engine can be parsed from the scripting files.
- switched the types of the internal 'self' and 'stateowner' parameters so that they get assigned correctly. I can't tell if this will error out if fields get accessed from the caller with the wrong class, but for actual scripting to work these must be correct.

The committed 'actor.txt' can be parsed successfully, with the exception of a few subclass references that cannot be resolved yet.

bdbc7c3fb7 - removed CreateDamageFunction, because it's no longer needed for defining a 'damage' constant. 2016-10-11 14:43:17 +02:00

6989b81688 - extended the grammar so that the DECORATE function declaration list can almost be used as-is, with the sole exception of requiring any action function to declare a return type, even if it is void.
This adds:
 * builtin types color, state and sound.
 * ending a parameter list with an ellipsis to declare a varargs list. (A_Jump uses this.)
 * allowing to declare optional arguments by giving them a default value.
 * adding an 'action' qualifier for function declarations.

3b19887637 - implemented the Defaults property initializer.
This uses the same property and flag tables as DECORATE with a few changes:

 * it sets the parse mode to strict, so that several DECORATE warnings are now errors.
 * trying to change a deprecated flag will print a warning.
 * setting of editor numbers, spawn and conversation ID id not possible. Use MAPINFO to do this.
 * all subclass flags must use the qualified name now (e.g. +ALWAYSPICKUP will print an error.)
 * the scriptable Damage property is not yet implemented. This will require a special case with a differently named property in the processing function because in the AST it is no longer possible to distinguish between a damage value and a constant damage function.

084bf8c576 - fixed: VisibleAngle and VisiblePitch actor properties require both parameters to be present, but the second one was set to optional. 2016-10-11 00:23:50 +02:00

2b9af0176c - changed grammar for a class's default block to look and act like DECORATE, so that it can hook into the same property dispatcher.
This had been defined as a regular compound statement but in the context this will be used in, that makes very little sense, because all it can do is set some constant values.
The most important thing here is that it doesn't provide an unnecessary learning curve to its users and doing it this way will not only ensure that but also avoid redundant documentation.
To allow initialization of other user-defined properties it will require some extensions but that's a job for later and can just as easily be done in the current framework, rather than throwing everything out and start from zero.

31ca5a1900 Added OverlayX/Y(int layer)
- Retrieves the X/Y positions of an overlay.
- A_OverlayFlags and A_OverlayOffset now interpret a layer of 0 to mean 'use this calling layer'.

e84d6a06d8 - changed PClass:AddField so that it doesn't create defaults if none are present. The ZScript compiler will not create any defaults until after all fields have been added and this function created bad data if it was run on a class without defaults.
- added checks for duplicate field names.
- moved the tree node symbol tables out of PSymbolTreeNode to the worker data. That symbol is a bad location because it restricts the usefulness of the symbol class which is also needed for variables which use different AST structs.
- fixed some memory management issues with the work classes for the compiler that became apparent after moving the symbol tables in there. In several places these were copied around, possibly losing data.

ad43f2bc7e - parse the list of class/struct fields and add the PField entries to their type.
- fixed a few issues with trying to access a class's Type before it got initialized.

49f18c0a19 - renamed the symbol tables holding the tree nodes so that the code becomes clearer to read. Necessary because the unclear naming caused:
- fixed: The tree nodes for classes and struct members were stored in the global tree nodes table.
- sort variable declarations into their own list for processing.

08f313d011 - implemented complete resolving of constants - both global and class-local.
This uses a different algorithm as the old implementation - instead of recursively resolving unknown symbols it will first collect all constants from all scopes and then process them in one operation, doing multiple passes over the list until no more constants can be resolved anymore.

5bb6bb31ca - added ProcessStruct, analogous to ProcessClass.
Now everything should be in place to resolve all constants - inside and outside classes or structs.

d139ee9f68 - give the 'default' block its own node type in the AST.
- group a class's body the same way as the global AST. Only partially implemented so far so that constants can be processed.

82ac2081b6 - create struct types.
- fixed class creation. There was an infinite loop and some missing checks for native classes.
- do not write the compiler's symbols to the same symbol table as the output. The output must go to GlobalSymbols but the internal symbols must go to a namespace specific table that can be discarded after compilation.

b71e8d09ed - create class types from the AST.
This is the first thing the compiler has to do to get access to the class's symbol table. Of course at this point the final size of a class is not known yet so these are currently all treated as tentative.

Christoph Oelckers
994bb4fc7a - started to make ZScript parser work on real-life data. It will now read a lump named ZSCRIPT which is a list of filenames to be compiled.
- place generated symbols into GlobalSymbols instead of a scratch table that will be discarded right away.
- allow the state object to change source file scanners (I hope this works, but the old implementation was unable to do more than one with with a parse state so I had to change it.)
- It can now parse constants.txt and insert everything in it into the global symbol table and make subsequent DECORATE compile properly.

d819aafcf3 - changed handling of duplicate classes in DECORATE.
Instead of replacing the original, the second class will get renamed now, using the originating file as an identifier. In the vast majority of cases this should do exactly what is needed: Create an unconflicting second class that can coexist with the original. Unless the class is used by name this should eliminate all problems with this, but so far I haven't seen anything that used them by name.

This is choosing the lesser of two evils. While some mod out there may get broken, the old setup meant that the first class of a given name could not be written out to a savegame because it was not retrievable when loading it back.

06ca41f8b5 - do not declare PNamedType::Outer as DObject.
Ultimately we may have to get a fully qualified name out of this, so Outer should be a type that can handle this feature. The new class for this is currently used as base for PType and PSymbol so that PNamedType inherits from it and maybe later a namespace symbol can, too.

ee66d22034 Revert "- added an option to disable the pickup screen flash."
This reverts commit 2d320a2e86.

The feature has been superseded by pickup_fade_scalar and is no longer needed.

d7bb5bb41e - fixed: ZCC_OpInfoType::FindBestProto was missing checks for exact match of the required conversion before testing if it is a F32->F64 conversion.
Of course, since 0 means that there is no conversion it also means that there is no data that could be checked.

c56d2eecb0 - rewrote AActor::DestroyAllInventory so that it clears the item's link to its owner and the owner's inventory list before destroying them.
There have been reports about crashes in here with Linux that point to some of the code that gets called here doing unwanted things on the owner, so with these links cleared that should no longer be possible.

15cbf4bae6 - fixed: DecoHandleRuntimeState must check all parent classes when trying to determine if the target is a valid state. It should also ensure that both the calling and target state belong to the same actor. Although unlikely it cannot be entirely ruled out that a bogus index randomly points to a seemingly valid state elsewhere. 2016-10-04 09:28:19 +02:00

594b344be9 Don't use MIN<short> when clamping topclip.
- This was fine with fixed point numbers, since they could never be
  outside of short range when converted to regular ints. With floating
  point numbers now, that condition no longer holds.

37d61167ea - hotfix for a RapidJSON bug: If the Writer tries to process an INF or NaN value, it aborts and leaves the writer in a broken state, unable to recover. Changed so that it writes a 0 value so that the resulting JSON at least parses correctly. 2016-10-02 18:50:37 +02:00

865863ab6f - fixed: AFastProjectile did not work properly for perfectly vertically moving missiles. Like AActor::Tick it needs to ensure that a tiny bit of lateral movement is present so that collision detection and the Effect() function work as intended. 2016-10-02 14:37:26 +02:00
