This UD Function I made creates a list with 3 strings for the 3 cords of a vector.

With many requests on how to easily store a vector to a list, mainly for purposes in storing a llGetPos() only to capture the x and y cords, this is a simple way.

For Example <lsl>list thislist = Vector2List(llGetPos());</lsl> As a list, would output <lsl>list thislist = [x, y, z];</lsl>

Function <lsl>list Vector2List(vector v){ 

   return [v.x, v.y, v.z];

}</lsl>

A Bad Example

Do Not Do This <lsl> list Vector2List(vector v){ 

   return [v.x, v.y, v.z];

}

default { 

   touch_start(integer total_number)
   {
       vector pos = llGetPos();
       list thislist =  Vector2List(pos);

       string x = llList2String(thislist,0);
       string y = llList2String(thislist,1);
       string z = llList2String(thislist,2);
       llOwnerSay("X Axis: " + x);
       llOwnerSay("Y Axis: " + y);
       llOwnerSay("Z Axis: " + z);
   }

} </lsl>

Here is the correct way to do this

<lsl> default { 

   touch_start(integer total_number)
   {
       vector pos = llGetPos();
       llOwnerSay("X Axis: " + ((string)pos.x));
       llOwnerSay("Y Axis: " + ((string)pos.y));
       llOwnerSay("Z Axis: " + ((string)pos.z));
   }

} </lsl>

A Good Example

<lsl> list Vector2List(vector v){ 

   return [v.x, v.y, v.z];

}

default { 

   touch_start(integer total_number)
   {
       list size = Vector2List(llGetScale());
       list sorted_size = llListSort(size, 1, 0);
       llOwnerSay("<"+llList2CSV(sorted_size)+">");
   }

} </lsl>
