This is another RLV plugin I wrote. It is used in a Ball. On touch it allows to choose an avatar within a range and tries to capture the selected avatar, forcing them to sit on the ball.

<lsl>// ~capture Script V1.0 // drop into a ball // // constants integer DEBUG = FALSE;

float TIMER_TIMEOUT = 60.0; float TIMER_LOCKED = 900.0; integer RANGE_CAPTURE = 20;

integer RELAY_CHANNEL = -1812221819;

// texts string MSG_NO_SENSOR = "No avatars in sensor range."; string MSG_MENU_IN_USE = " is using the menu. Please try again in a while."; string MSG_CHOOSE_AV = "Choose avatar:"; string MSG_TIMEOUT = "Dialog timeout. Please touch again to retry.";

// internal use integer dialog_handle; integer dialog_channel; key avatar_victim = NULL_KEY; integer channel;

list sensor_keys; list sensor_names; key avatar_menu;

// write a log message in DEBUG mode log(string message) {

   if (DEBUG) llOwnerSay("MENU: " + message);

}

// out a message to the user out(string message) {

   llSay(0, message);

}

capture(key avatar) {

   relay(avatar, "@sit:" + (string)llGetKey() + "=force");

}

lock(key avatar) {

   relay(avatar, "@unsit=n");

}

release(key avatar) {

   relay(avatar, "@unsit=y");
   relay(avatar, "!release");

}

// write a message to the RLV Relay relay(key avatar, string message) {

   if (avatar != NULL_KEY)
   {
       llSay(RELAY_CHANNEL, llGetObjectName() + "," + (string) avatar + "," + message);
       log("RLV: " + llGetObjectName() + "," + (string) avatar + "," + message);
   }

}

init() {

   dialog_channel= -(integer)(llFrand(100000 - 10000) + 10000);
   dialog_handle = llListen(dialog_channel, "", NULL_KEY, "");
   llListenControl(dialog_handle, FALSE);
   avatar_menu = NULL_KEY;

}

// default state default {

   // on state entry: show dialog
   state_entry()
   {

   on_rez(integer start_param)
   {
       channel = start_param;
       init();
   }
   // av touched me
   touch_start(integer total_number)
   {
       key id = llDetectedKey(0);
       // check if menu is in use

       {
           out(llKey2Name(avatar_menu) + MSG_MENU_IN_USE);
           return;
       }
       avatar_menu = id;
       llSensor("", NULL_KEY, AGENT, RANGE_CAPTURE, PI);
   }
   // no av in sensor range
   no_sensor()

       out(MSG_NO_SENSOR);
   }
