View Full Version : points at object selection pivots

03 March 2012, 10:07 AM
Hi, I am trying to write a simple script that will allow me to create a point helper(s) at the pivot(s) of a selected object/objects. I have looked on scriptspot but the available script is no longer available. I use MEL mostly and understand the basic requirement for doing this requirement in MAYA, but am having problems getting the for loop right. I have made a start which makes a point helper at the origin for each of the selected objects which are in an array, but I am just having a bit of a stumble at the syntax for writing the rest. Not sure if I need a counter for loop such as:

for (i = 0; i == names_array.count; i++)

but am not sure if the syntax is correct.

Any pointers would be greatly appreciated. I have some Maxscript resources to go through, but am pressed at the moment to be able to divert any time to absorb it and am hoping to get a quicker response that I can implement asap. The code below is probably in need of tidying up, but seems to be a decent start.

Many thanks in advance.

names_array = for i in $* collect
sort names_array

for i in 1 to names_array.count do

Point pos: [0,0,0]

i'd do something like:

selectionArray = selection as array

for i = 1 to selectionArray.count do
myPoint = Point pos: selectionArray[i].pivot = ("Point_"+selectionArray[i].name)

hey Malcolm,

I wanted to same thing a while back, so wrote a quick script as part of my rigging toolbox. Hopefully it will be useful to pick apart and see what is going on - it's essentially matt's code with a UI!

rollout PointParentRo "Point Daddy" width:165 height:155
fn SetHelperDisplayFlags size cross centermarker box axistripod =
for i in selection where classof i == point do
i.size = size
i.cross = cross
i.centermarker = centermarker

thanks very much guys, this is a massive help. am having lots of fun getting used to Maxscript again, so this is truly appreciated. :applause:

Hope I can return the favour one day.
