Hey.

I want to find out if there is a "free space" for entity to spawn it at player's origin. so I need to ignore the particular player who is spawning an entity and find out if the entity collides with anything around it. How do I do it?

If I understood correctly, use traceline/tracehull + IGNORE_MONSTERS flag.

I understand how the traceline works, but could you please explain what is tracehull and how it works?

TraceHull is same as TraceLine, but only difference (as the name suggests) is that it traces a hull (a volume) instead of a line. It just has one additional parameter that says what hull type to use. Search around, there are numerous examples.

Untested, I took the linked code and made minor tweaks.

PHP Code:

new Float:fOrigin[ 3 ]; //Need to set origin in question here 
    
if ( Is_Hull_Vacant( fOrigin , id ) )
{
    //ok to use origin
}

stock bool:Is_Hull_Vacant( const Float:Origin[ 3 ] , id )
{
    new tr , Hull = ( pev( id , pev_flags) & FL_DUCKING ) ? HULL_HEAD : HULL_HUMAN;
    engfunc( EngFunc_TraceHull , Origin , Origin , 0 , Hull , id , tr );
    return bool:( !get_tr2( tr , TR_StartSolid ) || !get_tr2( tr , TR_AllSolid ) );
}
