realXtend can run a version of script that is very similar to LSL but NOT LSL!
Many command from LSL are recognized and used but the syntax is alterned and require extensive exploration for any complicated LSL command such as llSensor/llSensorRepeat/llRequestPermission
Hence, embedding existing LSL command in python is a hit and miss process for many at the moment.
The key script that is used to do a few things:
- IF (people within range) then
- SHOUT to the person about being tracked for the FIRST time
- Ask for permission to track user.
- IF (POS/ROT not BOTH EQUAL ZERO) THEN
- Get Time Stamp
- Get Position Information
- Get Rotation Information
- Output into FILES? (not possible in SL version of the Script)
}
This is the SecondLife version of the tracking script
//This version tracks user, their cam pos and rot at predeterimined interval //Setting detection range to 5 meters float detRange = 5.0; //Setting detection period to 1 sec float detPer = 1.0; //Setting total detction cycle integer detCycle = 0; //Setting up detection target key detTarget; vector charVec; rotation charRot; vector camVec; rotation camRot; integer loopTime; //how frequently the loop is run integer runTime = 0; //keep track of how many time the script has ran. string msg; string msg1; string msg2; default { //touch state. touch_start(integer numberDetected) { // activates the sensor. Look for avatars (i.e. not moving objects) on all sides of the object llWhisper(0,"Starting Detection Runs"); //Request permission to track camera pos/rotation llRequestPermissions(llDetectedKey(0), PERMISSION_TRACK_CAMERA); } run_time_permissions(integer perm) { llSay(0,"Reached RTP"); if(PERMISSION_TRACK_CAMERA & perm){ llSensorRepeat("", "", AGENT, detRange, PI, detPer); } } //When object sensed. Passed on number deteced as parameter sensor (integer numberDetected) { //Notify number and name and all the first time notice item. //Return number detected. llWhisper(0, "Detected in total, " + (string)numberDetected + " avatar(s).");
llWhisper(0, "Detected " + llDetectedName(0) + llGetTimestamp());
//Get Camera Position 3D Coordinate
//Returns a VECTOR camVec = llGetCameraPos(); //Get Camera Rotation //Returns a ROTATION camRot = llGetCameraRot(); llWhisper(0, "CPos: (" + (string)camVec.x + "," + (string)camVec.y + "," +(string)camVec.z + ")"); llWhisper(0, "CRot: (" + (string)camRot.x + ","+ (string)camRot.y + ","+(string)camRot.z +","+ (string)camRot.s + ")"); charVec = llDetectedPos(0); charRot = llDetectedRot(0); llWhisper(0, "Pos: (" + (string)charVec.x + "," + (string)charVec.y + "," +(string)charVec.z + ")"); llWhisper(0, "Rot: (" + (string)charRot.x + ","+ (string)charRot.y + ","+(string)charRot.z +","+ (string)charRot.s + ")"); } no_sensor() { llWhisper(0, "Nobody is near me at present."); } }
