Help Custom Force to Match Object

[docgonzzo]

Thanks for the response! Excellent support here as usual







I was wondering if you could please post a good example of how to use the solver externalForces array. I tried the code below, but this is throwing a NullReferenceException runtime error on the for loop line.

Code:

    public ObiRope myRope; //this is assigned in Start()

    private void FixedUpdate()
    {

        for (int i = 0; i < myRope.solverIndices.Length; ++i)
            myRope.solver.externalForces[i] = myForce;

    }

In fact, this experiment below produced both a NullReferenceException runtime error, and the actual length of the array in the console

Code:

    private void FixedUpdate()
    {

        Debug.Log("myRope.solverIndices.Length: " + myRope.solverIndices.Length);



    }

NullReferenceException: Object reference not set to an instance of an object
ObiRopePlanetGravity.FixedUpdate () (at Assets/ObiRopePlanetGravity.cs:55)


myRope.solverIndices.Length: 10
UnityEngine.Debug:Log (object)
