Pointcontents should return CONTENTS_SOLID if you're in the void.
Part of the map compilation process is to 'fill the outside' with
contents_solid.
So a simple
If ( UTIL_PointContents( position ) & CONTENTS_SOLID ) )
{
In a solid, or the void
}
Should work.
Noclip around and test it with this command:
CON_COMMAND_F( dbg_contents, "dbg contents", FCVAR_CHEAT )
{
CBasePlayer *pPlayer = UTIL_GetCommandClient();
if ( !pPlayer )
return;
int contents = UTIL_PointContents( pPlayer->GetAbsOrigin() );
if ( contents & CONTENTS_SOLID )
DevMsg("in solid\n");
DevMsg(" Contents: %i\n", contents );
}

Subject: [hlcoders] Detecting point is outside world
Hey all, very simple question that I can't seem to find the answer to -
how
to tell if a point is outside the game world or not?
I've added an ability allowing players to teleport a short distance,
including through walls, to our HL2MP OB mod. This is great, and the
code
successfully avoids getting the player stuck inside world brushes or
anything else when teleporting. It is unfortunately possible for them to
teleport to completely outside the world geometry, and I can't work out
how
to stop this. I've tried my hull traces using various likely-looking
masks &
collision groups, and have looked at all the UTIL_PointContents flags,
but I
can't see how to determine if a point is outside the world or not.
I've also looked through gamemovement.cpp, as players don't fall when
they
teleport outside the world, so something must be stopping them, as they
aren't "in a solid" - but nothing jumps out at me. So, does anyone know
how
to determine if a point / trace / entity is completely outside the world
geometry?
The best "hacky" method I can come up with is testing if a
several-thousand-unit-long trace can be done in any direction
(up/down/n/s/e/w), and if any can, assume its outside. I'm sure there's
a
point contents method, but I can't work it out. Help would be
appreciated.
Thanks
