{{函数详情
|函数名 = Function: vector llDetectedGrab( 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 <0.0, 0.0, 0.0> if number is out of range or if called from an event other than the touch event.

|注意事项=
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1
<pre>
default
{
state_entry()
{
llSetStatus(PRIM_PHYSICS,TRUE);//This allows the object to be "grabbed" and dragged
}
touch(integer num_detected)
{
llSay(0,(string)llDetectedGrab(0));//Be prepared for a great amount of chatted info.
//The faster you move the mouse while grabbing the object the greater the offset becomes.
//This is not due to the speed but the reaction time of the turn around of the physical prim,
//thus an offset (distance from grab to prim center) is created and measured by this function.
}
}
</pre>

示例2
<pre>
/******

Simple llDetectedGrab illustration, rez a prim and add this script.
The prim will become a cone that follows mouse grabs.

Click and hold the mouse button down on the object, then:
- Drag left and right to move parallel to the camera focal plane.
- Drag up and down to move to and from the camera.
- Hold down Ctrl, then drag up and down to move vertically.
