The global "tags" can be iterated upon for every unique tag which is set in the
level. If a tag is set on a sector/line/thing, it will be included. Taking the
length of "tags" will give you the number of these unique tags. (If a tag is
set on multiple sectors/lines/things, it will only be counted once though.)
For sectors, lines and mapthings, call the field "tagged". This function takes
one argument, which is the tag. The return value can be iterated over for all
the sectors/lines/things with that tag. The length can also be taken for the
number of such objects. If no argument is given, the global tag is default.
* create new file lua_polyobjlib.c
* made a stub LUA_PolyObjLib function
* added META_POLYOBJ to lua_libs.h
* updated makefile, CMake and MSVC project files for lua_polyobjlib.c
Basically any function that calls fopen() is gone,
except the ones created by me.
And no access to stdin/stdout/stderr
through io.read()/io.write().
Not really harmful but why would you want that in SRB2.
my P_SearchBlockmap_* functions are now a single searchBlockmap function, you can choose between "objects" and "lines" with the first arg to decide what to iterate through. I also rearranged the argument order a bit for easy stack cleanup etc
I'll remove the old stuff later, don't worry, it's disabled for now
Angles now go from 0 to 0xFFFF (360 degrees == FRACUNIT) instead
of using a full UINT32. Lua only has one number type, so signedness
gets in the way of using angle_t directly. This handling of angles
matches up with how ZDoom ACS scripting and the like does it.
I also changed all the integer casts and pushes of fixed_t to
their own macro in preperation for possible future seperation.
