[Closed] Select objects through loop??

Hi Gibbz,

This will help you along your way!

for h in helpers do -- iterate through all of the helpers in the scene
(
if (classof h==dummy) and (isgrouphead h==false) then -- check to see that the object is a dummy, and not a group head
(
format "	%	%
" h.name h.transform	 -- format the transform (to a file?)
)
)

or this

    output_file = createfile ("c:\dummys.txt") --output to path
    for h in helpers where matchPattern h.name pattern:"Dummy*" do format "%
" h.pivot to:output_file
   close output_file
    

Additional: If your dummy object is not a standard helper and is instead a mesh called dummy, just swap ‘helpers’ in the above code for ‘objects’.

Helpers and classOf() are your friends in this case. Helpers is a virtual array that contains every helper object in the scene. ClassOf will tell you the class of whatever you pass in as a parameter.

To do things only to any dummies in the scene you can loop over Helpers and check each member to see if it’s a dummy. If so, act upon it.

for MyHelper in Helpers do
(
if classOf MyHelper == Dummy then
(
<do stuff>
)
)

So, to grab all the dummies in a scene and write their pivot information to a file the script would be:

 output_file = createfile "c:\dummys.txt"

for MyHelper in Helpers do
(
if classof MyHelper == Dummy then
(
format “% %
” MyHelper.name MyHelper.pivot to:output_file
)
)

close output_file

That creates the file c:\dummy.txt and writes the name and pivot (seperated by a tab) of every dummy in the scene to the file

ok sweet, thanks guys
ill check it out tonight after work.

Ok guys, that works fine, but max doesnt seem to use meters(ive setup the scene to be in meters, but it outputs an max units)…

Is there a way to output as meters? ive tryed addig the following…

units.MetricType #Meters

but it doesnt seem to help.

Edit: ok i found a hack, just divide by 39.37…

Thanks for your helkp guys

Ok trying ot make a variation of the script that get all the vertecis in a editpoly mesh and writes t othe file in the same way…

 units.MetricType #Meters
 output_file = createfile "c:\dummys.txt"
 myVerts = $.numverts 
 
 -- subobjectLevel = 1 --converts to vertex mode
 -- $.EditablePoly.SetSelection #Vertex #{1} --select vertex 1
 
 for i = 1 to myVerts do
 (
 
 meshshop.getvert Box01 1 --Box01 is my object
 format "%	%
" MyHelper.name (MyHelper.pivot/39.37) to:output_file --divide to convert from max to meters
 
 )
 
 close output_file
 

But the getVert never works, it only ever spits out errors, even when trying things in the listener

Thanks

Hi Gibbz,

Try replacing this line :

meshshop.getvert Box01 1 –Box01 is my object

with :

meshshop.getvert $Box01 i –Box01 is my object

Hey thanks I put it in but im still getting an error

the following error

  
  <File:c:\dummys.txt>
  8
  -- Error occurred in i loop; filename: D:\Program Files\Autodesk\3dsMax8\Scripts	uts	ut3_grabvertcoords.ms; position: 268
  --  Frame:
  --   i: 1
  --   myVertex: undefined
  --   meshshop: undefined
  -- Unknown property: "getVert" in undefined
  OK
  OK
  

my updated code…

  units.MetricType #Meters
  output_file = createfile "c:\dummys.txt"
  myVerts = $.numverts 
  
  --subobjectLevel = 1 --converts to vertex mode
  --$.EditablePoly.SetSelection #Vertex #{1} --select vertex 1
  
  for i = 1 to myVerts do
  (
  
  myVertex = meshshop.getvert $Box01 i --Box01 is my object
  format "%	%
" i (myVertex/39.37) to:output_file --divide to convert from max to meters
  
  
  )
  
  close output_file
  

uh…it’s meshop not meshshop
