//instructions: 

//1 this script outputs an expression which you need to past in your expression editor

//2 before running the script replace the given variable values with your object names.

//3 after running the script copy the output expression ((found in your output window of the script editor)) into the expressin editor



// *note this script goes under the assumption that you are using a spine that does not use

// *auto orientation when turned on instead your spine uses the world orientation.  

// *also, you will need to create two cubes or curves for controllers on the spine.

//variables - EDIT TO YOUR NEEDS

//nodename == what we are ctrling minus any number following it

//if your first joint is called Spn1 input "Spn"

// StartJnt folowing number?

//if your first joint is called Spn1 input 1

     	int $strtJnt = 1;



//controller name == what controls the nodename?

	string $controllername = "BC";

	string $Subcontrollername = "BC1";



//Switch to add in sub ctrl

// at what joint do you want to start using the subctrl

//Joint limit == end joint

//how many joints are in your chain?

	int $Jntlimit = 7;



//xyz rotation

//input the joints axis you want to control

//if you want to control x and y you would input {"x","y"}
