If done as before, forward-declared classes cannot be found, and the immediate resolving is only needed for constant expressions, so explicitly enabling it in the 4 places where it is needed ensures that those unresolvable expressions remain intact until the final processing pass righr before the code generator is started.
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.
