Testing with Adventures of Square this mostly works, but it is clear that a list of old and deleted CVARs still needs to be added so that any items referring to those can be eliminated as well. Some stuff is still slipping through that refers to features which no longer exist.
Sadly, some mods are truly careless enough to modify the engine internal menus to add their own things, which should have no business whatsoever in there.
As an example, in a D4D version released in May, the Display Options menu is showing quite a bit of outdated content and missing important settings.
- added a '-nocustommenu' command line options. This is for disabling user menus that intentionally or accidentally disable crucial menu features.
- do not allow replacement of the main options menu. This menu contains engine-critical settings and may change at any time when new features get added. For now it will be the only one that gets protected but this may soon be extended to some of its submenus as well.
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.
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.
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.
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.
The manager class cannot be scriptified because it provides the internal implementation which may change at some point in the future. It also encapsulates all access to the file level because if that part is not protected, modders could write malware mods.
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.
* everything related to scripting is now placed in a subdirectory 'scripting', which itself is separated into DECORATE, ZSCRIPT, the VM and code generation.
* a few items have been moved to different headers so that the DECORATE parser definitions can mostly be kept local. The only exception at the moment is the flags interface on which 3 source files depend.
