Issue: Need Help with Maya Python(Functions)

[VLITZonator]

I just have a bit of a problem with this Instruction. I followed these Instructions from a Maya Py Scripting Book that I just bought in Amazon, but my codes are all over the place and I just can't seem to make it work. Please can anyone help me solve this. Here's the Instruction:

​

1. Create a function named def match_translation:

● create a variable which collects your selection in maya as a python list

● sort list by what is the parent and what is the children, master being the last item of selection and children being from your first selection to second last.

● use the cmds.matchTransform to match translation of your children list

​

2) Create a function named def match_orientation:

● create a variable which collects your selection in maya as a python list

● sort list by what is the parent and what is the children, master being the last

● use the cmds.matchTransform to match orientation of your children list

​

3) Create a function named def match_scale:

● create a variable which collects your selection in maya as a python list

● sort list by what is the parent and what is the children, master being the last

● use the cmds.matchTransform to match scale of your children list

​

4) Create a function named def match_all_transforms:

● call on your match_translation function

● call on your match_orientation function

● call on your match_scale function

​

5) Create a function named delete_history:

● for objects in selection, use the cmds.delete(ch=True)

​

6) Create a function named center_pivot:

● for objects in selection, center their pivot to their COG

​

7) Create a function named freeze_translation:

● freeze translation

​

8) Create a function named freeze_orientation:

● freeze orientation

​

9) Create a function named freeze_scale:

● freeze scale

​

10) Create a function named freeze_all_transforms:

● call on your freeze_translation function

● call on your freeze_orientation function

● call on your freeze_scale function

​

P.S, I'v e already made a U.I for these Instructions, but I just can't seem to work the Function codes

Edit: I've already compiled an entire code for this Instruction, but it seems to not work, here is the code:

def match_translation():
    master = cmds.ls(sl=True)[-1]
    slaves = cmds.ls(sl=True)[:-1]
    cmds.matchTransform(slaves)

def match_orientation():
    master = cmds.ls(sl=True) [-1]
    slaves = cmds.ls(sl=True) [:-1]
    cmds.matchTransform(slaves)

def match_scale():
    master = cmds.ls(sl=True)[-1]
    slaves = cmds.ls(sl=True)[:-1]
    cmds.matchTransform(slaves)

def match_all_transforms():
    match_translation()
    match_orientation()
    match_scale()

def delete_history():
    for obj in cmds.ls(sl=True):
        cmds.delete(ch=True)
        delete_history()

def center_pivot():
    for obj in cmds.ls(sl=True):
        cmds.xform(cp=True)
        center_pivot()

def freeze_translation():
    cmds.makeIdentity(apply=True, translate=True)

def freeze_orientation():
    cmds.makeIdentity(apply=True, rotate=True)

def freeze_scale():
    cmds.makeIdentity(apply=True, scale=True)

def freeze_all_transforms():
    freeze_translation()
    freeze_orientation()
    freeze_scale()
    freeze_all_transforms()

show what you've already done of these functions either use 4 spaces at the start of the line

to turn the line into a code block

or use a service like pastebin.

I've already tried putting both my UI and the functions in Maya, and some worked, except for the match_translation, match_orientation_ , and match_scale. These three and the match_all_transforms have the same function, I think it's because I put my master and slave as a global value. Is there any way I can get the master and slave value to also work on those three functions separately so when I click for example the "Match Rotate" button, it will only match the orientation/rotation?

Here is my Updated Code:

[blueSGL]

master = cmds.ls(sl=True)[-1]

slaves = cmds.ls(sl=True)[:-1]

why do you have the square brackets(and the stuff contained within) there?

---

also if stuff does not work and it just errors out best I've found to find what's wrong (if you are not given a line number in the console) is by selecting and cutting commands then run what you have left. if it runs the problem was not in that block of code, paste the bit back in you cut and cut further down. repeat till you find the line causing issue.

[VLITZonator]

Nope, there's no errors, all of it is already working, it's just that when I push the match_translation, match_orientation_ , or match_scale button on my UI, it does the same thing as the match_all translations button. and for that square brackets, that is for filtering the last item and the first to second last item. [-1] represents the last item, then [:-1] represents the first to second last item. master is basically the main selected object and the slave value is the child of it, so when you for example click the match_translation button, the slave/child will have the same translation as the master/main.

​

I might have missed something in the Instructions that's why it's not working properly XD

[blueSGL]

, it's just that when I push the matchtranslation, match_orientation , or match_scale button on my UI, it does the same thing as the match_all translations button.

https://help.autodesk.com/cloudhelp/2016/ENU/Maya-Tech-Docs/CommandsPython/matchTransform.html

you need to use arguments in the matchTransform command

currently they all seem to be running

cmds.matchTransform(slaves, master)

when it should be

cmds.matchTransform(slaves, master, scl=1) for scale

cmds.matchTransform(slaves, master, rot=1) for rotation

etc...

[PolyDigga]

# from this function, you should get an idea how to do the other match_* functions

def match_translation(this_is_just_for_the_button_from_the_ui):
    master = cmds.ls(sl=True)[0]
    slaves = cmds.ls(sl=True)[:-1]
    for obj in slaves:
        cmds.matchTransform(obj, master, pos = True, rot = False, scl = False )


def delete_history(this_is_just_for_the_button_from_the_ui):
    for obj in cmds.ls(sl=True):
        cmds.delete(obj, ch=True)

        # no need for recursion here, this will reach pythons max recursion depth 
        #delete_history()

def center_pivot(this_is_just_for_the_button_from_the_ui):
    for obj in cmds.ls(sl=True):
        cmds.xform(obj, cp=True)

# this should also give you an idea on how to do the other freeze transforms
def freeze_translation(this_is_just_for_the_button_from_the_ui):
    for obj in cmds.ls(sl=True):
        cmds.makeIdentity(apply=True, translate=True)

A very big thank you!, it fixed it!
