This reverts commit e9cbb0b223, reversing
changes made to d6e3fc0567.
The merge just copied the obsolete FxFloatCast from master without any conflict so it all had to be removed again.
- Member variables are now declared all in one place: InitThingdef(). They
are not partially defined in thingdef_expression.cpp and further refined
in actor.txt.
- This left ParseNativeVariable() parsing only functions, so it has been
renamed to ParseNativeFunction().
- Note that their declarations in InitThingdef() are expected to be
temporary.
- This is RandomPick but for floats. Considering what RandomPick
translates into in the scripting branch, I hope I don't regret not using
type inference on RandomPick instead of creating a new keyword.
- So now you can do something like this for an action:
{
if (health > 1000)
{
A_Scream;
}
else
{
A_XScream;
}
}
Yes, the braces are required. Because I see too many instances where
somebody writes an if statement in ACS and doesn't understand why it
doesn't work right because they forgot braces.
- Fixed: Not actually putting an action between { and } would crash.
- You can now call several actions from one frame by grouping them between
curly braces. i.e. :
POSS G 3 { A_Pain; A_Log("Ow! That hurt!"); }
I will probably add an `if (something) { blah; blah; } else { wah; wah; }`
construct later, but that's the extent of the munging I plan for DECORATE. The
real work goes to the scripting language, not here. But if this branch is
getting merged to master sooner than later, here's an immediate benefit
from it right now.
- This replaces the general extensibility that had existed formerly
in thingdef_function.cpp. Parameter parsing for function calls is
shared with state parameter parsing. Functions are defined exactly in
the same way as action functions, but without the 'action' keyword.
- Fixed: Integer constants passed to pick() need to manually generate load
instructions, since FxConstant::Emit() will just return a constant
register with its value.
- Fixed: VMFunctionBuilder::RegAvailability::Reuse() didn't actually
calculate a proper mask. Also added another assert to this function.

- Added register reuse to VMFunctionBuilder for FxPick's code emitter.
- Note to self: Need to reimplement IsPointerEqual and CheckClass, which
were added to thingdef_function.cpp over the past year, as this file no
longer exists in this branch.
- Constants can be strings, but the existing PSymbolConst couldn't handle
them. The old PSymbolConst is now PSymbolConstNumeric, and the new
PSymbolConst is a now a baseclass for it and PSymbolConstString.
- The type systems used by PField and FxExpression are completely
incompatible, but I think I got the differences taken care of as far
as ParseNativeVariable(), ParseUserVariable(), and FxClassMember are
concerned.
- Support for declaring native bool variables has been removed for the time
being. It wasn't used anyway.
- Removed PSymbolVariable.
- For the purposes of getting constant values from expressions, the only
class where Resolve doesn't duplicate the functionality of
EvalExpression was FxConstant. So, every other class has had its
EvalExpression taken away, and FxConstant has had it renamed to GetValue.
- Now that the VM supports degrees, use those instructions when emitting
code for cos and sin DECORATE expressions. (This looks like it also
fixed a bug where sqrt also did the degree to radian conversion.)
- Removed EvalExpression() implementations from some subclasses of
FxExpression that don't make any sense in the context of evaluating a
constant value.
- This all became vestigial code after the relevant information was all
moved into FStateTempCall. Now that the MBF code pointer code has been
converted, I can be sure it wasn't still used anywhere.
- Changed Actor's Damage property into an actual function. All access to the damage property
must now be done through GetMissileDamage. actor->GetMissileDamage(0, 1) is equivalent
to the former actor->Damage, for the case where actor->Damage was not an expression. (I
suppose I will probably need to make a thunk for DECORATE expressions that want to read it.)
- Cleaned up some decorate expression evaluation functions that are no longer used.
SVN r3919 (scripting)
actors with names that conflicted with preceding actors from being freed, even though they
can still be accessed via PClassActor::AllActorClasses, which gets iterated over in a number
of places. (e.g. Zen Dynamics defines a Grenade actor, although there is one in zdoom.pk3 now.
The Zen Dynamics' version would not go in the TypeTable, so it would be collected on map load,
leading to a crash when attempts to access it through AllActorClasses are made.)
SVN r3908 (scripting)
one name in its label. This avoids the alloca and security cookie calls.
- Consolidated lots of copy-pasted code in thingdef_expression.cpp to install helper functions
into FindDecorateBuiltinFunction().
