MaxScript镜像函数

看到有网友需要写的，其实镜像就是缩放改为负数

Fn MirrorObject argObjects argAxisName =
(
    local axisNames = #(#x,#y,#z)
    if FindItem axisNames argAxisName  ==  do
    (
        throw "the second parameter error !!! -- valid values:#x,#y,#z"
    )

    local mirrorMatrix = matrix3
    if argAxisName == #x do mirrorMatrix.row1 *= -
    if argAxisName == #y do mirrorMatrix.row2 *= -
    if argAxisName == #z do mirrorMatrix.row3 *= -

    local tempArray = #()
    maxOps.CloneNodes argObjects  expandHierarchy:true  newNodes:&tempArray
    for tempObject in tempArray where
    (
        tempObject.parent == undefined  or FindItem tempArray tempObject.parent  ==
    )
    do
    (
        tempObject.parent = undefined
        tempObject.transform *= mirrorMatrix
    )
    tempArray
)
