LlGetBoundingBox

Template:Needs Translation/

函数名
Function: list llGetBoundingBox( key object )
参数：key object –同一区域组、化身或者物体的UUID
返回值：以局部坐标返回一个列表，该列表是对象相对于其根prim的边界框。

注意事项
注意事项 不管object是否是非根的prim，都会返回该对象的边界框。如果object是一个坐在对象上的代理，这也适用——返回坐在对象上的边框(包括代理的形状)。 附件没有自己的边界框(因为它们没有物理交互[1])，相反角色的边界框会被返回。

示例

default//An avatar bounding box ruler thingy { state_entry() { llSetStatus(STATUS_PHANTOM, TRUE); } touch_start(integer total_number) { key target = llDetectedKey(0); list box = llGetBoundingBox(target); vector center = llDetectedPos(0) + (llList2Vector(box, 0) + llList2Vector(box, 1)) * 0.5; vector size = llList2Vector(box, 1) - llList2Vector(box, 0); llSetPrimitiveParams([PRIM_POSITION, center, PRIM_SIZE, size]); llSetText("Name: " + llDetectedName(0) + ", UUID: " + (string)target + "\nBounding Box Size: " + (string)size, <1.0, 1.0, 1.0>, 1.0); } } // Enclose a named object in the tightest possible box // that is aligned with the object's root prim axes. // Drop this script in a box near the object to enclose // (must be in a 10m range) string ObjectNameToEnclose = "SearchMe"; key UUID; default { state_entry() { llSensor(ObjectNameToEnclose, "", ACTIVE | PASSIVE, 10, PI); } sensor(integer n) { UUID = llDetectedKey(0); llSetTimerEvent(1); } timer() { list info = llGetObjectDetails(UUID, [OBJECT_POS, OBJECT_ROT]) + llGetBoundingBox(UUID); vector pos = llList2Vector(info, 0); rotation rot = llList2Rot(info, 1); vector corner1 = llList2Vector(info, 2) * rot + pos; vector corner2 = llList2Vector(info, 3) * rot + pos; vector size = llList2Vector(info, 3) - llList2Vector(info, 2); llSetPos((corner1 + corner2) * 0.5); // Set position to the midpoint (average) of the corners llSetRot(rot); llSetScale(size); } }
