WaterLevel returns 0 for an npc even when completly submurged so long as it's on the ground

I assume this is likely because the game is performing a volume check at the NPC's position (the very bottom of it's feet) which would be right on the edge of the water volume. Either way, I don't know of any other way to check for water at a point in the world. Any ideas?

Take a look at this: [url]https://github.com/Facepunch/garrysmod-issues/issues/631[/url]

The last bit of code works great for players:

[lua] function PLAYER:WaterLevel( )
local _pos1 = self:GetPos( );
local _halfSize = self:OBBCenter( );
local _pos2 = _pos1 + _halfSize;
local _pos3 = _pos2 + _halfSize;
if ( bit.band( util.PointContents( _pos3 ), CONTENTS_WATER ) == CONTENTS_WATER ) then
return 3;
elseif ( bit.band( util.PointContents( _pos2 ), CONTENTS_WATER ) == CONTENTS_WATER ) then
return 2;
elseif ( bit.band( util.PointContents( _pos1 ), CONTENTS_WATER ) == CONTENTS_WATER ) then
return 1;
end

return 0;
end[/lua]

Just have it use the ENTITY meta-table instead of the PLAYER metatable.

That's perfect! Thank you very much :)

A minute ago I'd come up with a hacky solution that involved spawning a small prop inside of the npc and parenting it to the npc to be used as a water sensor. Your solution is much better!
