3dsmax maxscript：如何按照我选择的顺序获得 array/list 个顶点？

Question

我正在为 3dsmax 编写一个工具，它要求用户按照在数组中选择顶点的顺序获取选定的顶点，但到目前为止，这个 returns 顶点是按照它们创建的顺序传递的：

sel = getCurrentSeletion()
selvets = vsel[1].selectedVerts

如何使用 maxscript 以我在 3ds max 中选择的顺序获取选定的顶点？

如果在 maxscript 中没有办法，在 python 中有没有办法做到这一点？

Answer 1

如果你只关心顶点的位置，你可以使用pickPoint函数代替。否则进行回调以更新选择更改并记录差异。一个例子是（如果您当前的节点是可编辑多边形）：

try destroyDialog selectVerts catch()
rollout selectVerts ""
(
    local verts, currentSel

    fn collectVerts event nodes =
    (
        local sel = polyop.getVertSelection $
        local newVerts = sel - currentSel
        local removedVerts = currentSel - sel

        for v in removedVerts do if (local index = findItem verts v) > 0 do deleteItem verts index
        for v in newVerts do append verts v
        currentSel = sel
    )

    local callback = nodeEventCallback mouseUp:on enabled:off subobjectSelectionChanged:collectVerts

    checkButton chbSwitchCallback "Select verts"

    on chbSwitchCallback changed state do
    (
        if state and isKindOf $ Editable_Poly then
        (
            verts = #()
            currentSel = polyop.getVertSelection $
            callback.enabled = on
        )
        else
        (
            callback.enabled = off
            print verts #noMap
        )
    )
)
createDialog selectVerts
