Im having trouble getting two definitions to speak to each other using a UI. I would like to create a bunch of locators place them in the scene and name them. Then in a different definition create some joints and use the locators name and position to position the joints and name them according to the locators I previously created.
My problem is the variable named rootJnt is not being recognized in the joint creation definition. All others are except rootJnt. I don't understand why, all the other variables are being recognized. Can some one please explain?

To have access to your variables between two functions, you have to define them in an outer scope. In your case _endOutLoc, _startOutLoc, _rootLoc are defined locally to ProxySkel function and they are not visible to jointsCreate function In additional to that, there are several other mistakes
- as it was mentioned in the comments to your question, _rootLoc have to be passed with index 0, because it stores value as a list, not as a string
- if you are using parent constraint for the alignment, I would guess you want to delete them once the alignment is finished
- there is no need to call parent command for the joints, as they are already parented in the order of cmds.joint calls. Here is a note from documentation "In the creation mode, a new joint will be created as a child of a selected transform or starts a hierarchy by itself if no transform is selected." if you don't want such behaviour, you should clear the selection
- cmds.window('window1',menuBar=1) have to be always called, not inside the existance window condition, otherwise the UI elements will be attached to the script editor window
here is an updated script
from maya import cmds
global _endOutLoc
global _startOutLoc
global _rootLoc
def proxySkel (self): global _endOutLoc, _startOutLoc, _rootLoc target = cmds.ls (selection = True) DDD = cmds.textField (textNam, query = True, text = True) # CREATE THE LOCATOR _endOutLoc = cmds.spaceLocator (position = (0, 0, 0), name = DDD + '_locEndOut') _startOutLoc = cmds.spaceLocator (position = (0, 0, 0), name = DDD + '_locStartOut') _rootLoc = cmds.spaceLocator (position = (0, 0, 0), name = DDD + '_locRoot') # MOVE END LOCATOR IN SPACE cmds.move (5, 0, 3, _endOutLoc, absolute = True) cmds.move (0, 0, 3, _startOutLoc, absolute = True) return _endOutLoc, _startOutLoc, _rootLoc
def jointsCreate (self): global _endOutLoc, _startOutLoc, _rootLoc if None in [_endOutLoc, _startOutLoc, _rootLoc]: print('locators are not created yet') return target = cmds.ls (selection = True) DDD = cmds.textField (textNam, query = True, text = True) # CREATE THE JOINTS rootJnt = cmds.joint (position = (0.0, 0.0, 0.0), name = _rootLoc[0] + '_jnt') endOutJnt = cmds.joint (position = (0.0, 0.0, 0.0), name = _endOutLoc[0] + '_jnt') startOutJnt = cmds.joint (position = (0.0, 0.0, 0.0), name = _startOutLoc[0] + '_jnt') # PLACE THE JOINTS INTO SPACE rootConst = cmds.parentConstraint (_rootLoc, rootJnt, mo = False) endOutConst = cmds.parentConstraint (_endOutLoc, endOutJnt, mo = False) startInConst = cmds.parentConstraint (_startOutLoc, startOutJnt, mo = False) # DELETE CONSTRAINTS AFTER ALIGNMENT cmds.delete (rootConst, endOutConst, startInConst) # CREATE THE JOINT HIERARCHY #cmds.parent (endOutJnt, rootJnt) #cmds.parent (startOutJnt, endOutJnt)
if(cmds.window('window1',q=1,ex=1)): cmds.deleteUI('window1')
cmds.window('window1',menuBar=1)
cmds.columnLayout()
textNam = cmds.textField(width=150, text='Name', backgroundColor=[0.6233005264362554, 1.0, 0.9765011062790875])
cmds.separator()
cmds.rowLayout(numberOfColumns=3)
