llDetectedVel

Summary

Function: vector llDetectedVel( integer number );

36	Function ID
0.0	Forced Delay
10.0	Energy

Returns a vector that is the velocity of detected object number.

Index of detection information

number does not support negative indexes. Returns <0.0, 0.0, 0.0> if number is not valid sensed object.

Specification

llDetected* functions only work if called from within Detection events (collision, collision_start, collision_end, sensor, touch, touch_start, touch_end) or in functions called by Detection events. They will fail silently and return unusable values if called during other events.

Caveats

• If number is out of bounds the script continues to execute without an error message.
• Events that enable the llDetected* functions always return at least one detected item.
  • Detection events are not raised if there is nothing detected.^[1]
  • The detection event's items detected parameter is initially never less than 1.^[2]

Examples

<lsl> //Tells the name and velocity of all near-by avatars. default {

    state_entry() {
         llSensor("", "", AGENT, 10000, 10000);
    }
    sensor(integer num) {
         integer i = 0;
         while (i < num) {
              llOwnerSay(llDetectedName(i) + " is moving at " + (string)llVecMag(llDetectedVel(i)) + " m/s.");
              ++i;
         }
    }

}

1. ^ The exception is no_sensor but it doesn't enable llDetected* functions.
2. ^ Like all event parameters, the user can overwrite the initial value.
