EQEmulator Forums - Find Nearest Object/Wall & Z value of floor @ point?

Ok, so I gave it a few runs, tried to add in debug messages to figure out what was going wrong, but have to throw in the towel and see if you guys can spot what I am doing wrong here. Here is the sample code I wrote for the Hate Step effect ( recall - warps a character forward in the direction they are facing x distance; its an SK AA on live ).

Code:

                        case SE_ShadowStepDirectional:

                        {

                                double look_heading = GetHeading();

                                look_heading /= 256;

                                look_heading *= 360;

                                look_heading += 180;

                                if(look_heading > 360)

                                        look_heading -= 360;



                                // note: x and y are backwards

                                // the -8 is just a multiplier to increase the distance I arbitrarily picked, nothing more

                                double new_x = ( spells[spell_id].base[i] * -8 ) * sin(double(look_heading * 0.017453289 ));

                                double new_y = ( spells[spell_id].base[i] * -8 ) * cos(double(look_heading * 0.017453289 ));

                                double new_z = GetZ( );



                                // try to see if a zone wall is in the way

                                VERTEX        start, end, result;

                                FACE        *triangle        = NULL;



                                start.x                = GetX( );

                                start.y                = GetY( );

                                start.z                = GetZ( );

                                end.x                = GetX( ) + new_x;

                                end.y                = GetY( ) + new_y;

                                end.z                = GetZ( );



                                bool        b = zone->zonemap->LineIntersectsZone( start, end, 1.0f, &result, &triangle );

                                Message(15, "Debug: result is %s: %lf %lf %lf", ( b == true ? "true" : "false" ), result.x, result.y, result.z );

                                if( b )

                                {        // result should give us the point we hit

                                        Message(15, "Debug: intersect @ %lf %lf %lf", result.x, result.y, result.z );

                                        new_x        = result.x;

                                        new_y        = result.y;

                                }

                                else

                                {        // otherwise, set new_* to values we wanted to use

                                        new_x        += GetX( );

                                        new_y        += GetY( );

                                        Message(15, "Debug: used2 x,y %lf %lf", new_x, new_y );

                                }

                                // now lets find the z-axis value

                                VERTEX        org;

                                org.x        = new_x;

                                org.y        = new_y;

                                org.z        = GetZ( );

                                Message(15, "Debug: old z %lf", org.z );

                                //new_z        = zone->zonemap->FindBestZ( MAP_ROOT_NODE, org, &result, &triangle );

                                new_z        = org.z - zone->zonemap->FindClosestZ( org );

                                Message(15, "Debug: new z %lf", new_z );



                                // I have no idea why, but I had to double the GetHeading return value for this function to work for me, hence the *2

                                CastToClient()->MovePC( zone->GetZoneID(), zone->GetInstanceID(), new_x, new_y, new_z, GetHeading( ) *2, 0, PCStep );

                                Message(15, "%s %s", GetName(), spells[spell_id].cast_on_other );

Thus far, I still go into / through walls and seem to always get returned a 0 from FindBestZ ( note - I've been testing int he Arena ), either implementation, while the 'real Z' shown by a #loc command can be vastly different, plus or minus.

I can paste in some of the logs too if that helps, but I figured it may be hard to envision in pure numbers when one is in a wall or not... :)

Anything stand out as to what I am doing wrong? Seems like a rather simple thing to implement but I put no limits as to what I can screw up! :grin:
