- Since DECORATE's return statement can only return the results of
function calls (I do not want to spend the time necessary to make it
return arbitrary expressions), here are three functions to get around
this limitation:
* A_State - Returns the state passed to it. You can simulate A_Jump
functions with this.
* A_Int - Returns the int passed to it.
* A_Bool - Returns the bool passed to it.
- e.g. If you want to return the number 3, you use this:
return A_Int(3);
If you want to jump to a different state, you use this:
return A_State("SomeState");
- The A_Jump family of action functions now return the state to jump
to (NULL if no jump is to be taken) instead of jumping directly.
It is the caller's responsibility to handle the jump. This will
make it possible to use their results in if statements and
do something other than jump.
- DECORATE return statements can now return the result of a function
(but not any random expression--it must be a function call). To
make a jump happen from inside a multi-action block, you must
return the value of an A_Jump function. e.g.:
{ return A_Jump(128, "SomeState"); }
- The VMFunction class now contains its prototype instead of storing
it at a higher level in PFunction. This is so that
FState::CallAction can easily tell if a function returns a state.
- Removed the FxTailable class because with explicit return
statements, it's not useful anymore.
With late resolving it cannot be guaranteed at this point and caused some incorrectly compiled code. Since the cast gets optimized away anyway when not needed there's no point being this selective with applying it.
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.
- 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.

- 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.
- After StateParams was removed in commit 4a1fbdb, the expressions for
default paramaters that ParseActionDef() created went nowhere and were
lost. Properly throw them away by deleting them as soon as they've been
parsed.
- 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)
This is compatibility optioned with COMPAT_STAIRINDEX. Also added a compatibility setting for
Eternal Doom MAP25 which relies on Doom's original broken behavior.
- added a few sanity checks for duplicate actor names in DECORATE. ZDoom will now print more warnings
and all crash cases should be properly handled but since this is still an error this will not work
properly in all circumstances. For example, if you have a duplicate name all classes that inherit
from the original definition will not survive a savegame if they reference a state belonging to that
class at the point of saving.
- Print 'tried to register class more than once' in red to highlight it.
- fixed: actors may not replace themselves.
SVN r2158 (trunk)
only has 64 entries and is not precise enough. It now uses finesine instead.
- fixed: When compositing a multipatch texture any patch that is a multpatch
texture itself and contains rotations may not be composited directly into
the destination buffer. This must be done with an intermediate buffer.
- Fixed: Drawing a slider in the options menu did not scale the x-coordinate.
- Fixed: If the alt HUD had to draw negative numbers the minus sign was misplaced
due to incorrect texture coordinate calculations.
- changed option menu scaling for widescreen modes so that it doesn't scale down
so quickly.
- made some error messages in DECORATE that don't affect the parsing non-fatal
so that the parser can continue to find more problems.
SVN r2076 (trunk)
A_SetUserVar/SetUserVariable/GetUserVariable now take a variable name
instead of an array index. A_SetUserArray/SetUserArray/GetUserArray
have been added to access elements in user-defined arrays.
SVN r1933 (trunk)
a different default terrain than a generic solid surface.
- added format char processing to A_Print(Bold) and all printable messages
that can be defined in DECORATE.
- Fixed: The railgun code ignored MF3_ALWAYSPUFF.
- added desaturated translations.
- added optional state parameters to A_ReFire and A_GunFlash and A_CountdownArg.
