Description: This script finds the cardinal direction that an object is currently pointing towards, and sets it in text above the object that the script is in.

Edit: Now fixed to work even when avatar is standing still.

How to use: Put inside an object either attached to your avatar or on a moving object.

CODE

default
{
state_entry()
{
llSetTimerEvent(0.1); // set a timer event for every tenth of a second
}

timer()
{
string direction; // this is the variable we will set the text with
vector vel = llRot2Fwd(llGetRot());// get the current velocity
integer x = llRound(vel.x); // round the x value of the velocity and assign it to a new variable
integer y = llRound(vel.y); // round the y value of the velocity and assign it to a new variable


//Keep in mind the following when reading the following part of this script: when one travels perfectly east at a speed of 1.0, their velocity is <1.0,0,0>. Therefore, if they were traveling west,
//it would be <-1.0,0,0>. If they were traveling north, it would be <0.0,1.0,0.0>. If they were traveling south, it would be <0.0,-1.0,0.0>. We dont deal with the Z value of the velocity at all
//because cardinal directions are based on a two-dimensional coordinate plane.
if((llAbs(x) > llAbs(y)) && (x > 0)) // if the absolute value of X is greater than Y, then we are traveling mostly east or west. If X is positive, then we are traveling east.
{
direction="East";
}
else if((llAbs(x) > llAbs(y)) && (x < 0)) // if the absolute value of X is greater than Y, then we are traveling mostly east or west. If X is negative, then we are traveling west.
{

direction = "West";
}
else if((llAbs(y) > llAbs(x)) && (y > 0)) // if the absolute value of Y is greater than X, then we are traveling mostly north or south. If Y is positive, then we are traveling north.
{

direction = "North";

{

direction = "South";
}
else if((llAbs(y) == llAbs(x)) && (x > 0 && y > 0)) // if the absolute value of Y is equal to X, then we are in an intermediate direction. If both X and Y are positive, then we are traveling nort //heast, because EAST is positive on the X axis and north is positive on the Y axis.
{

direction = "Northeast";
}
else if((llAbs(y) == llAbs(x)) && (x < 0 && y > 0)) // if the absolute value of Y is equal to X, then we are in an intermediate direction. If X is negative and Y is positive, then we are traveling //northwest

direction = "Southwest";
}
else if((llAbs(y) == llAbs(x)) && (x > 0 && y < 0)) // if the absolute value of Y is equal to X, then we are in an intermediate direction. If X is positive and Y is negative, then we are traveling //southeast

{

}
llSetText(direction, <1,1,1>, 1.0); // set text on the object to what direction we are moving in
