{{函数详情
|函数名 = Function: vector llDetectedVel( integer number );
|参数= 参数：integer number–Index of detection information number does not support negative indexes.
|返回值= 返回值：Returns the vector velocity of detected object or avatar number.


|注意事项=
*If number is out of bounds this function returns <0.0, 0.0, 0.0> and 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]


|示例=
<pre>
//Tells the name and velocity of all near-by avatars.
default 
{
    state_entry() 
    {
        // Scan once for avatars within a 96 metre radius sphere
        llSensor("", "", AGENT, 96, PI);
    }
    sensor(integer num) 
    {
        // num will initially be 1 or more. When num is 1, the index of the detected avatar will be zero       
        while(num--) 
        {
            llOwnerSay(llDetectedName(num) + " is moving at " + (string)llVecMag(llDetectedVel(num)) + " m/s.");
        }
    }
