Assigning a unity component variable issue

Question

I'm using Unity 3 and I'm trying to perform a simple assignment of the variable linearLimit>limit within the ConfigurableJoint component. I'm using the code below but I keep getting the error "Cannot modify a return value, try placing it within a variable first". Am I doing something wrong?

//My Code

ConfigurableJoint cj = gameObject.GetComponent(); cj.connectedBody = objectToGrab;

     cj.xMotion = ConfigurableJointMotion.Limited;
     cj.yMotion = ConfigurableJointMotion.Limited;
     cj.zMotion = ConfigurableJointMotion.Limited;
     
     float newLimit = 1.0f;
     cj.linearLimit.limit = newLimit;

//Unity's public Accessor/Mutator for that variable

public float limit { get {return this.m_Limit; } set {this.m_Limit = value; } }

Hi

to set a configurable joint limit you have to:

 ConfigurableJoint cj = gameObject.GetComponent();
 cj.connectedBody = objectToGrab;
 
 cj.xMotion = ConfigurableJointMotion.Limited;
 cj.yMotion = ConfigurableJointMotion.Limited;
 cj.zMotion = ConfigurableJointMotion.Limited;

 // setup a SoftJointLimit instance to modify...
 SoftJointLimit newLimit = new SoftJointLimit();
 newLimit.limit = 1.0f;
 newLimit.*otherVars* = cj.linearLimit.*otherVars*; // if needed
 // ... and set the joints limit to the SoftJointLimit instance
 cj.linearLimit = newLimit;

hope it helps ;)

Thanks. It doesn't mention that anywhere on the documentation for that page
