Groups and single objects Q

[Anonymous]

Hi

How can i loop over my scene objects and print names with the following conditions:

1.If its a single object, just print the object name
2. If its a group, only print the the "top group" name (not groups within groups or the
member names)


When I run a loop **- for o in objects do print o.name -** I get single object as
well as groupmembers. And when I loop over the helpers where isGroupHead, I get
the groups (and the groups inside groups....)


Any help would be greatly appreciated 🙂

for obj in objects do
    if not isGroupMember obj then
        print obj.name

Works for me!

Guess it did 🙂 Thank you !

I'm trying to eliminate printing out Helpers, but Since groups are
part of the helper superclass I'm not sure how to write the expr.

This is what I've written so far. Maybe someone can help me shorten the
script or point out my mistakes.

Another thing; If I want to output the obj.names to a txtfile and then open the
createfiledialog. Do I have to write a fn to hold the result of the objectloop?

        on exec_btn pressed do
            (
            for obj in objects where 
                superclassof obj != shape and   -- Checks to see if the obj is of the superclass shape
                superclassof obj != camera and  -- Checks to see if the obj is of the superclass camera
                superclassof obj != light and   -- Checks to see if the obj is of the superclass light
                classof obj != TargetObject and  -- To avoid listing targetobjects
                
                    not isGroupMember obj do    -- Makes sure the Groupmembers are not included
                    (                             
                    
                        print (("\n")+"The Object named: "+(obj.name)+("is of superclass: ")+ (superclassof obj as string))
                        
                    )
            )

Tried to make a function to hold the loop, like this:

    function do_default =
        (
        for obj in objects where 
                superclassof obj != shape and
                superclassof obj != camera and
                superclassof obj != light and
                classof obj != TargetObject and
                not isGroupMember obj do print (obj.name+("\n"))
        )

Since I want to have checkboxes to include/exclude cameras/helpers/Shapes etc.

Is this an ok way to do it?

That's no problem, you could also make a struct and use this function in the struct. That keeps the code nice and clean.... you can then use the script in stdscripts and call your struct function everytime you need it. But you'll have to pass some parameters to the function to dis/enable the options you want included.

struct mystruct (
  fn do_default options = (etc),
  fn another_function option1 option2 = (etc2),
  etc
)

call the function

mystruct.do_default options  -- pass the options to the fn

You see that you can group functions... almost the same as a class/obj in c++ or whatever OOP language. Look it up in the reference lots of good stuff on that.

Thanks!

I feel my codebits are very inefficient and needlessly long.
Check out my script to see.

(Combos between the checkboxes (other that lights and cameras) and Output to txt isn't implemented yet)

[Anonymous]

Yes I think it's not very efficient this way 😉
Make 1 function and pass the "filters" as array and check in the function against the set filters. Going to sleep right now... maybe I can put something up tomorow, but read up on passing variables to function in the mxs help! You can easily pass the states of the checkboxes directly to the function on exec_btn pressed, and sort it out in the function!

Passing variables to the function........puh!...
For a guy who started learning MAXScript 3 weeks ago,
that is quite a task 🙂

Is this more efficient?

global theClasses =#(superclassof,classof) 
global theFilter =#(shape,camera,light,TargetObject)
global ArrItemclass = 0
global ArrItemFilter = 0

function userChose ArrItemclass ArrItemFilter =
        (
            for o in objects where theClasses o != theFilter
            do print ((o.name as string)+("\n"))
        )

on exec_btn pressed do
(
    userChose 2 4
)

I've tried several solutions.
I feel this one will be the easiest to modify:

global MyCams   = for cams in objects where superClassof cams == camera  collect cams.name
global MyLights = for ls in objects where superClassof ls == light  collect ls.name
global MyShapes = for shps in objects where superClassof shps == shape collect shps.name
global MyDef    = for obj in objects where superClassOf obj != light and superClassOf obj != camera and
                  superClassOf obj != shape and classOf != TargetObject collect obj.name
global Nums     = 0

function userChose Nums =
        (
        if Nums == 1 do
            (
            print MyCams as string
            )
        )
    

I'm struggling with updating the objectprinting to include newly added objects. How can I have
my array update(live) and collect at runtime ?

Any help would certainly be welcome 🙂

Johan (Or anyone .. : )

Could you, if you find the time, explain how to pass variables from i.e. a checkbox state that affects the
outcome of a function, and how I can use it with the struct?

I'm having trouble finding good examples on how to do this 🙂



Thanks

There's different ways of doing these things. Really depends on how you build your tool. You can use the struct to build the UI from it. In that case you define the struct as global variable and you can access it anywhere.

global myStruct
  struct myStruct (
  fn doMyCalculations var1 = (),
  fn buildMyRollout = (
    rollout "name" etc
    (
      button bn1 "name" etc
      checkbutton ch1 "name"
    )
    on button pressed do mystruct.doMyCalculations ch1.state
  ),
)

That's only a principle description of how I do it, if you want to see an example of how I used it download: http://scripts.subd.nl/?f=JHN_userPropBuffer.ms or http://scripts.subd.nl/?f=JHN_FusionSplines.ms They both have the struct way of building a tool. Also interresting is to download some of Neil Blevins scripts on scriptspot and pick them apart.. that's how I got coding this way. Really the best way to learn is too pick other people scripts apart!

Thanks Johan!

I've written small 'exporter' script and tried to implement some global variables
to a checkbutton. (Save a maxfile and set the project folder before running the script.)

You must specify an object format : ie .obj in the textfield.

Any ideas on how to open the export dialog for the specified object ? (now , since i use the nopromt,
the latest settings will apply.)
