INM8, run this commandline from the Windows shell (MS-DOS window on Win98) to see a list of the flags:
blenderplayer.exe -h | more
(The “|” is the pipe key, found directly above the carriage return/enter key on most QWERTY keyboards). Apparently this list of flags is at least slightly incomplete, since the example shows a flag called “noaudio” being used which cannot be found in the list.
Here is the basic format for fullscreen:
blenderplayer.exe -f fw fh fb ff yourblend.blend
blenderplayer.exe -f width height bits-per-pixel frequency yourblend.blend
blenderplayer.exe -f 1024 768 32 60 yourblend.blend
runs “yourblend.blend” fullscreen, 1024x768, 32-bit, 60kHz.
You can also run commandline flags on a compiled runtime. For some reason, you need to provide a fake blend file name (the file doesn’t need to exist) for some features to work. For example:
MyCompiledRuntime.exe -p 10 10 640 480 blank.blend
Just as a note, you cannot use flags on a compiled runtime to run another blend.
