It's treated like a bool anyway, so might as well make it one.
This also necessitates updating every single instance where it or an
element inside it is used, too.
It looks like this may have been used earlier in development, judging
from the name, obviously, but right now it seems like it's used as an
error message if a main game level is asked for an invalid room (well,
only two of them - the Lab and Warp Zone). It should probably be
formalized into an error system, if we want to keep teststring, and also
people would never see it anyway because I don't think there's a
reliable and consistent way to trigger loading a non-existent room.
I have seen someone manage to load a non-existent Warp Zone room only
one time, but even then this teststring didn't pop up. So this
teststring doesn't even trigger in the right circumstances.
Also, when it does pop up, as far as I can tell it will stay onscreen,
which is kinda annoying. So I'm just removing this ancient relic from
the code.
This changes something like UtilityClass::String to help.String,
basically. It takes less typing this way, and is a neat effect of having
global args actually be global variables.
This commit removes all global args from functions on the entityclass
object, and updates the callers of those functions in other files
accordingly (most significantly, the game level files Finalclass.cpp,
Labclass.cpp, Otherlevel.cpp, Spacestation2.cpp, WarpClass.cpp, due to
them using createentity()), as well as renaming all instances of 'dwgfx'
in Entity.cpp to 'graphics'.
Following discussion on TerryCavanagh/VVVVVV#153, I suggested that
instead of reverting my M&P guards from TerryCavanagh/VVVVVV#124 (which
would only revert it for The Final Level, The Lab, Overworld, and The
Tower, leaving Space Station 1 & 2 and The Warp Zone alone which could
potentially cause the same problem that motivated
TerryCavanagh/VVVVVV#153), we should initialize the map data with 0s
instead.
This is to make sure that the room data of those areas are not
distributed with the M&P binary, even if they are already inaccessible
because of other M&P ifdefs (I tested).
