[TF2] How to check is the point on wall or on floor

There the code which checking can place on this point a sentry, but its working only on plate serfaces.
I want to change it to place on any surface(like engineer), but except walls.

How to change this code to make it to allow to creating not only plate surfaces, but not the walls?

PHP Code:


		
			


...

new Float:flPos[3];

if(GetClientLookPosition(client, flPos))

       if(CanBuildAtPosSentry(flPos))

...





stock bool CanBuildAtPosSentry(float fPos[3]){

    float fMins[3], fMaxs[3];



    fMins[0] = -20.0;

    fMins[1] = -20.0;

    fMins[2] = 0.0;



    fMaxs[0] = 20.0;

    fMaxs[1] = 20.0;

    fMaxs[2] = 66.0;



    TR_TraceHull(fPos, fPos, fMins, fMaxs, MASK_SOLID);

    return !TR_DidHit();

}

backwards

        return !TR_DidHit();



    return false;

Re: [TF2] How to check is the point on wall or on floor

Thanks, that works, but you mistaken, need to be fPlaneNormals[2] == -1.0, not 1.0

full right code, for copy pasters =)

PHP Code:


		
			
stock bool CanBuildAtPosSentry(float fPos[3]){

    float fMins[3], fMaxs[3];



    fMins[0] = -20.0;

    fMins[1] = -20.0;

    fMins[2] = 0.0;



    fMaxs[0] = 20.0;

    fMaxs[1] = 20.0;

    fMaxs[2] = 66.0;



    TR_TraceHull(fPos, fPos, fMins, fMaxs, MASK_SOLID);



    float fPlaneNormals[3];

    TR_GetPlaneNormal(INVALID_HANDLE, fPlaneNormals)

    if(fPlaneNormals[0] == 0.0 && fPlaneNormals[1] == 0.0 && fPlaneNormals[2] == -1.0)

        return !TR_DidHit();



    return false;

}

This may depend on the map, in css the map I've tested 1.0 on z was the floor but -1.0 was the ceiling. So keep that in mind, it's easy to change for slightly slanted surfaces as well.
