Point Constraint skip Axis parameter issue.

[tushar sankhala]

Hi,

I am writing an automated constraint string for one of the animator friend.

I am having an issue in the skip axis parameter of the point constraint command.

Try1:

myString = 'x'

cmds.pointConstraint( 'sph1', 'sph2', skip=[myString])   WORKS

Try 2:

myString = 'x'

myString += ","

myString += 'y'

cmds.pointConstraint( 'sph1', 'sph2', skip=[myString])   # Error: RuntimeError: file <maya console> line 1: Invalid argument for the skip flag. Specify x, y, or z. # 

Tried Different version of the input Like Putting them in single quotes or double quotes:

myString = '"x"'

myString += ","

myString += '"y'"

Can someone help?

Thanks in advance.

Hi,

the arguments need to be seperate strings within a list. How you have it, your passing in a list that looks like ["x,y"]. You need your list to look like ["x","y"]

try something like this:

skipList = ['x']
skipList.append('y')

cmds.pointConstraint( 'sph1', 'sph2', skip=skipList )

hi,

Your solution worked but i have one confusion 

how does that works when i have only one element like

myString = 'x'

cmds.pointConstraint( 'sph1', 'sph2', skip=[myString])

and this works,

problem comes when i have two axis to skip...

Thanks

myString = 'x'
cmds.pointConstraint( 'sph1', 'sph2', skip=[myString])

This works because your string is passed within a list to the argument.

skip=[myString] is not the same as skip=myString

so you were passing it skip=["x"] which of course works, but you needed to append another string to your list, instead of add to the string itself. which was giving you skip=["x,y"]

Hope that helps

sorry let me clarify. skip="x" would have worked too. since it's just one argument. But if you read the docs, it says multiple arguments need to be passed in as a list or tuple.
