- 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.
- This fixes crashes when quitting multiplayer games because the default
byte-for-byte copy caused PredictionPlayerBackup and the console player
to point to the exact same userinfo data and to both try and free it
when they are deleted.
- Make wi_noautostartmap a userinfo cvar. This allows it to be
communicated across the network and saved in demos. If any player has it
set, then the intermission screen will not automatically advance to the
next level.
- Instead of tying NoDelay behavior to OF_JustSpawned, use a new actor
flag, MF7_HANDLENODELAY. This only gets cleared once it has actually
been checked by Tick(). This is necessary because freeze mode delays the
initial run of Tick() past the initial spawn, so OF_JustSpawned will no
longer be set when it does the initial tick.
- Delay NoDelay processing if an actor is spawned dormant. Actors spawned
dormant have Deactivate() called before they tick, so MF7_HANDLENODELAY
will remain set as long as an actor is dormant. This allows the NoDelay
handling to occur as expected once it is activated.
- If the current user does not have write permissions for the directory
zdoom.exe is located in, use standard folder paths located in their home
directory instead. This is a common scenario when people put ZDoom into
Program Files. (Ironically, zdoom.ini used to be in AppData, buth then
people complained when it wasn't in the same directory as zdoom.exe, so
it got turned into zdoom-<user>.ini so at least it could retain some
multi-user support. I'm not sure when the AppData support was removed,
though, since it should have still been kept around for migrating
configs to the new name.)
Hexen did this with a call to A_BridgeRemove in Thing_Destroy which merely set a flag in the bridge object, which cannot be done safely in ZDoom because it's not guaranteed that the ball object calls A_BridgeOrbit and the garbage collector may delete the bridge actor before it can be checked so now the Bridge's Destroy method deletes all balls attached to the bridge object itself.
- Since the tokenizer never gives the parser negative numbers but always a
unary minus followed by a positive number, it seems reasonable to make
the parser smart enough to turn these into negative constants without
generating extra tree nodes.
- And since we're doing it for unary -, we might as well do it for unary +
as well and avoid extra nodes when we know we don't need them.
- For an enum like this:
enum { value1 = SOME_NUM*2, value2 };
Generate an increment expression for value2 of the form
(add (id value1) 1)
and not
(add (* SOME_NUM 2) 1)
- Instead of representating enumeration values with a special node type,
use the same ZCC_ConstantDef nodes that const_def produces. These are
created at the same scope as the ZCC_Enum, rather than being contained
entirely within it. To mark the end of enums for a single instance of
ZCC_Enum, a ZCC_EnumTerminator node is now appended to the chain of
ZCC_ConstantDefs.
- 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.
- Instead of having ZCC_ExprString, ZCC_ExprInt, and ZCC_ExprFloat,
just use a single ZCC_ExprConstant. It should simplify type
promotion and constant folding in the future.
- Constants can fill out the type field right away. Other expressions will need
to wait until a later pass, after names have been resolved, so they get
initialized to NULL.
