- The global symbol table was never marked by the GC, so anything pointed
only by it was fair game to disappear.
- Don't clear the global symbol table during DECORATE parsing. Junk in
there should be considered constant after initialization.
- AST nodes cannot be shared, because type conversion changes them in
place, and what's appropriate for one use is by no means appropriate for
all uses.
- Added ZCCCompiler class as a place to generate IR and symbols from an
AST. Right now, all it does is simplify constant expressions into
constant values.
- Do type promotion on the AST where appropriate.
- Added true and false tokens to the parser driver.
- PType::FindConversion() can find a path to convert one type to another.
This is completely generic and can handle any number of conversion
functions.
- Added ZDOOM_OUTPUT_OLDSTYLE (could probably use a more descriptive name) which causes CMake to vary the executable name by build type and place the exes and pk3s into the directory specified in ZDOOM_OUTPUT_DIR.
- ALL_BUILD will now launch ZDoom.
- Command-line console commands are executed before a level is entered, so
trying to use +warp to position yourself at a specific location will not
work. We now specially handle this command so that it does work.
- Added CF_INTERPVIEW flag for players. A_SetPitch/A_SetAngle and the
similar ACS APROPs set this when changing an angle. This forces the
renderer to interpolate the view angles instead of updating with the
latest mouse positions. The effect lasts one tick.
- To make camera textures pan in world units instead of texture units, you
can now add "WorldPanning" at the end of the cameratexture definition in
ANIMDEFS, after the "fit" specification. e.g.
cameratexture CAMTEX 128 128 fit 64 64 worldpanning
- Fixed: DThinker::Destroy(Most)ThinkersInList() were unreliable when
destroyed thinkers destroyed more thinkers in the same list.
Specifically, if the thinker it destroyed caused the very next thinker
in the list to also be destroyed, it would get lost in the thinker list
and end up with a NULL node. So just keep iterating through the first
thinker in the list until there are none left. Since destroying a
thinker causes it to remove itself from its list, the first thinker will
always be changing as long as there's something to destroy.
- Fixed: You could not set any CVARINFO-defined cvars from the command line
because command line console commands were executed before wads were
even loaded. Off the top of my head, I can't think of anything that would\
break by having them get executed after wads are loaded.
- Since the VM doesn't directly support the GT, GTEQ, and NEQ comparisons,
don't use them in the trees either. Instead, wrap them as LTEQ, LT, and
EQEQ inside a BoolNot operator.
- I can't believe I completely forgot to let the parser handle true and
false literals.
- Consolidate all the %include blocks in zcc-parse.lemon into a single
one, because Lemon all of a sudden decided it didn't like me having more
than one in the grammar file.
- Added a PBool type to represent boolean values with.
- This conversion has behavior similar to %g: It automatically behaves like
%f or %e based on the number of output characters. However, unlike %g,
this decision is also based on what will produce the smallest string
without truncating the output. The precision field (the * in %.*f) is
ignored. Converting a double to text with %H and then back to a double
should be lossless.
- Added TypeVoid for statements, which produce no type.
- Added TypeError for expressions whose arguments are incompatible.
- Pointers now derive from PBasicType instead of PInt. Since they have their own register sets in the VM, this seems to make more sense than treating them as integers.
If an actor is already targeting a goal, and Thing_SetGoal is used on
it, it would still be left targeting the old goal instead of the new
one. This messed up checks in A_Chase for walking towards a goal vs a
real target.
