I'm trying to check if a player is inside a building or not, so I want to check the vertical space above them for a roof or some sort of shelter above them. I'm not entirely sure how I would go about using TR_TraceHull (if that's what I should be using), if anyone has any examples that would be a great help, thanks!

No need for the whole point_viewthingie shabang.
But here's the snippet out of all of that that would show you how to find if he has a ceiling

PHP Code:

stock Float:findCeiling(target, Float:vecOrigin[3]) {
    decl Float:vecPos[3];
    new Handle:trace = TR_TraceRayFilterEx(vecOrigin, g_vecDown, CONTENTS_SOLID|CONTENTS_MOVEABLE, RayType_Infinite, TraceEntityFilterPlayer, target);

    if(TR_DidHit(trace)) {
        TR_GetEndPosition(vecPos, trace);
        //if(vecOrigin[2]-vecPos[2]>64) { // are they 60 units off the ground?
        //    PrintToChat(attacker, "\x04Airshot! \x01You hit \x04%N \x01in the air!", target);
        //    EmitSoundToClient(attacker, TF2DM_AIRSOUND, _, _, _, _, 1.0);
        //}
    }

    CloseHandle(trace);

    return vecPos[2];
} 


This would find the position of the ceiling directly above him. Simply do a distance check and you'll know if he's close enough.

TraceHull can do too. And sometimes it's more preferred.
