First, don't worry I don't plan to make a thread about my maxscripts needs everyday

Now, I was working with a small model today and wanted to know if there was a way in maxscript to shut mirror center seam ?

I'm using align to x to make sure my selection is alright, and want to move it to x=0 (without changing the yz position).
The align thing is no brainer, but I can't get my head around making my selection move to x=0 without changing the other positions.

move command is expecting a "x y z" argument while I can only provide x.

Is there a way to do that ?

Thank you in advance.

Ok, I got it, I looked at this script and copied the part I wanted.

Thanks to the author, I'm a noob with maxscript I would never have found it otherwise.

you need to go a bit lower level for this i think. polyOps are called for

aSelectedVerts = (polyop.getVertSelection $) as array
nSelectedVerts = aSelectedVerts.count

for i = 1 to nSelectedVerts do
(
	vertPosition = polyop.getVert $ aSelectedVerts[i]
	vertPosition.x = 0.0
	polyop.setVert $ aSelectedVerts[i] vertPosition
	
)

edit - beaten to it. Oh well

Thank you it's still a good thing you answered I will look at your code and try to understand it, copy pasting stuff is not the way to go. I prefer yours since it's only doing what I want so I can understand it better.

get an array of the currently selected vertices, polyop ops dont return arrays for this sort of thing, they return whats called a bitArray. because of this we use 'as array' to convert it into an array.

aSelectedVerts = (polyop.getVertSelection $) as array

we find how many verts are selected

nSelectedVerts = aSelectedVerts.count

we start a for loop from 1 to the number of selected verts

for i = 1 to nSelectedVerts do
(

we vertex index stored at position i in the array, and then use a polyOp to get that vertexs position.

	vertPosition = polyop.getVert $ aSelectedVerts[i]

we explicitly set the x position stored in vertPosition to 0.

	vertPosition.x = 0.0

Then we update the position of the vert

	polyop.setVert $ aSelectedVerts[i] vertPosition

)

OK thank you for the breakdown. Most of the time when trying simple scripts like that, I understand the functions, but have problems inputing the correct data type. (plugin an array instead of a integer for example).

That's my issue most of the time

Practices makes perfect I guess. But it will take a while I think. At least I'm more confident now than I was with mel scripting at the begining.

best thing to do is look up the max script help. check the data type functions return and expect as input and then read their help.

if you have a variable and you want to know its data type or class
type
classOf variable

Thanks for your help, I've a lot to learn here, but the possibilities are enormous. I think I'm starting to understand Perna about the importance of max customization to fix autodesk mistakes :>

It's a great tool in fact it's just so dry at first contact (well before ribbon tools that is)

I may be misunderstanding, but after you align your verts on on the X, can't you just type a zero into the X value beneath the viewport?

BeatKitano · Apr 2011

I could, but I'm lazy and want to be able to do all that with a hotkey (I don't need to align now as x=0 absolutely). Besides in expert mode that bar is invisible and I like my ui very simple
