Simulating Latitude/Longitude

#1 I would suggest using the terrain manager (see www.gorpe.com) and then finding a way to map from world-space to latitude/longitude space. Probably just scale the current xy co-ordinates of the player...

#2 last I checked, x,y,z was fro mthe origina of the map, even if you were on another tile?

This is the snippet I use to echo position to the console:

function serverCmdpositionEcho(%client)
{
// position echo
%pos_x = getWords(%client.player.getTransform(), 0, 0);
%pos_y = getWords(%client.player.getTransform(), 1, 1);
%pos_z = getWords(%client.player.getTransform(), 2, 2);
messageClient(%client.player.client,"","X = " @ %pos_x @ " Y = " @ %pos_y @ " Z = " @ %pos_z);

//speed echo
%speed = getWords(getControlObjectSpeed(), 0, 0);
messageClient(%client.player.client,"","speed = " @ %speed);

}

#3 Edward, I saw that code in another thread. Is there a way to bind that to a GUI element?

#4 One could use the same logic that TerrainManager uses to determine what terrain square it's dealing with given a set of world corrdinates.

Basicly treat all of the terrain blocks, with their own 256x256 grids, as part of a larger metagrid. That way if you know they xy location of an object on a terrain block, and you know the terrain block's xy position within the grid of terrin then you can calcuate the position of the object on the metagrid.

#5 //For what its worth, here's some code to convert
//between spherical and cartesian coordinates.

double radians(double a)
{ return a*(3.14159265359/180.0); }

double degrees(double a)
{ return a*(180.0/3.14159265359); }

void FromSpherical(
double r, double lon, double lat,
double& x, double& y, double& z
)
{
// origin of coordinate system is at longitude
// zero and latitude zero

// coordinates north of the equator or west of
// the prime meridian are negative
// EG: W113 N49 would be represented as -133 -49

// coordinates south of the equator or east of
// the prime meridian are positive
// EG: E30 S43 would be represented as 30 43

// convert input lon and lat degrees to radians
double rlat = radians(lat);
double rlon = radians(lon));
double cp = cos(rlat);
double sp = sin(rlat);
double ct = cos(rlon);
double st = sin(rlon);
//output coordinates in radius (r) units
x = r * ct * sp;
y = r * cp;
z = -r * st * sp;
}

void ToSpherical(
double x, double y, double z, double r,
double& lon, double& lat, double& alt
)
{
// input coordinates in radius (r) units
// r is assumed to include an altitude above the
// base spherical radius

// estimate geocentric altitude
alt = sqrt(x*x + y*y + z*z);
// output lon and lat in degrees
double rlat = acos(y / alt);
lat = -degrees(rlat);
double sp = sin(rlat);
double st = z / (-alt * sp);
double rlon = asin(st);
lon = -(180.0 - degrees(rlon));
alt = alt - r;
}

#6 Thanks :)
