Variable problem python

Coding

Hello all,
I am working on a tool for a tool set I am building in Maya and have ran into a small problem. I am running a few checks and decided to put them into separate functions and am losing my targeted variable and can not figure out why. Here is my code.


import maya.cmds as cmds


print("jointAdd.py Loaded")

win = "jointAdd"
selJoint = cmds.ls(sl=1)
selChild = cmds.select(selJoint, hi=1)
selChildP = cmds.ls(sl=1)
selChildFinal = selChildP[1]

def gui():
	if(cmds.window(win, q=1, ex=1)):
		cmds.deleteUI(win)
	if(cmds.windowPref(win, q=1, ex=1)):
		cmds.windowPref(win, r=1)
	
	cmds.window(win, t=win, w=300, h=125)
	
	cmds.columnLayout("baseCol")
	cmds.intSliderGrp( cw3=[75, 50, 100], field=True, label='Joint Addition', minValue=0,
	maxValue=15, fieldMinValue=0, fieldMaxValue=15, value=0 )
	cmds.button( l="Add Joints", w=290, c="jointAdd.orientCheck()")
	cmds.showWindow(win)
	
def orientCheck():
	'''
	select -d joint1 ;
	insertJoint joint1;
	// Result: joint3 // 
	joint -e -co -p -1.52704e-018 0.942082 0 joint3;
	insertJoint joint3;
	// Result: joint4 // 
	joint -e -co -p -3.51219e-018 1.51679 0 joint4;
	insertJoint joint4;
	// Result: joint5 // 
	joint -e -co -p -5.28356e-018 2.02961 0 joint5;
	'''
	#Check if the joints are oriented
	if(cmds.getAttr(selChildFinal + ".tx") > 0) and (cmds.getAttr(selChildFinal + ".ty") > 0):
		print("Joints are not oriented correctly")
	elif(cmds.getAttr(selChildFinal + ".tx") > 0) and (cmds.getAttr(selChildFinal + ".tz") > 0):
		print("Joints are not oriented correctly")
	elif(cmds.getAttr(selChildFinal + ".ty") > 0) and (cmds.getAttr(selChildFinal + ".tz") > 0):
		print("Joints are not oriented correctly")
	else:
		print("Joints are oriented!")
		getAxis()
def getAxis():
	#Figure out joint child axis
	if(cmds.getAttr(selChildFinal + ".tx") > 0):
		childAxis = ".tx"
	elif(cmds.getAttr(selChildFinal + ".ty") > 0):
		childAxis = ".ty"
	elif(cmds.getAttr(selChildFinal + ".tz") > 0):
		childAxis = ".tz"
	else:
		print("Child is too close to subdivide")
	
	print(selChildFinal + " is oriented down the " + childAxis + " axis.")

I do not know where I am losing it but I get this error in maya:


# Traceback (most recent call last):
#   File "<maya console>", line 1, in <module>
#   File "C:/Users/Carey/Documents/maya/scripts\jointAdd.py", line 50, in orientCheck

#     childAxis = ".tx"

If you’re running this in the script editor it works fine, but if you’re running it from an external script, which it appears you are “jointAdd.py”, than those variables need to be stored and passed into the defs, right now, as soon as the script runs through those variables go away.

so you can encapsulate the cmds.ls(sl=True) into a def and then have the other defs call that def to capture it’s return value.

OH, ok. That would explain why it would be finding a empty list. Cool, thanks.
