NullReferenceException Error
When I try to run my script I get this error:
NullReferenceException Movementscript.FixedUpdate () (at Assets/Movementscript.js:7)
Here is my script:
var speed=20.0;
function FixedUpdate () {
var torque=Vector3(Input.GetAxisRaw("Vertical"), 0, -Input.GetAxisRaw("Horizontal"));
if(torque.magnitude > 0.0){
torque=Camera.main.transform.TransformDirection(torque);
rigidbody.angularVelocity=Vector3.Lerp(rigidbody.angularVelocity, torque * 2, 0.3);
}
if (Input.GetButton("W"))
{
rigidbody.AddRelativeTorque (2, 0, 0);
rigidbody.AddRelativeForce (2, 0, 0);
}
if (Input.GetButton("S"))
{
rigidbody.AddRelativeTorque (-2, 0, 0);
rigidbody.AddRelativeForce (-2, 0, 0);
}
if (Input.GetButton("A"))
{
rigidbody.AddRelativeTorque (0, 0, -2);
rigidbody.AddRelativeForce (0, 0, -2);
}
if (Input.GetButton("D"))
{
rigidbody.AddRelativeTorque (0, 0, 2);
rigidbody.AddRelativeForce (0, 0, 2);
}
}
I don't see any problem with the script, so can someone explain to me what's wrong?
I tested this script and it gave "$$anonymous$$issing Component Exception: There's no 'Rigidbody'... at line: 7". I had no rigidbody, of course, just to test the script. With a rigidbody added, no errors were flagged. Just a shoot in the dark: do you have a main camera?
Eh em. One of my helpers clearly came in and deleted the rigidbody... Sorry for uhm. Wasting time.
Even after I fixed the rigidbody I get the same error.
Don't you need to tell Unity which rigidbody you're referencing? Rigidbody is a component of a Game Object, I believe.
like, Machine1.rigidbody.AddRelativeTorque
Like Sparkplug94 says, to this script works, its need to be attached to an object that have a rigidbody attached.
Anyway, why are you using Input.GetButton to keys(letters)? That letters are mapped in Edit > Project Settings > Input? If no, the best way to use Keys is Input.GetKey.
Borgo is correct. Try this:` var speed=20.0; function FixedUpdate () {
var torque=Vector3(Input.GetAxisRaw("Vertical"), 0, -Input.GetAxisRaw("Horizontal"));
if(torque.magnitude > 0.0){
torque=Camera.main.transform.TransformDirection(torque);
rigidbody.angularVelocity=Vector3.Lerp(rigidbody.angularVelocity, torque * 2, 0.3);
}
if (Input.GetKey("w")) {
rigidbody.AddRelativeTorque (2, 0, 0);
rigidbody.AddRelativeForce (2, 0, 0); }
if (Input.GetKey("s")) {
rigidbody.AddRelativeTorque (-2, 0, 0); rigidbody.AddRelativeForce (-2, 0, 0); }
if (Input.GetKey("a")) { rigidbody.AddRelativeTorque (0, 0, -2); rigidbody.AddRelativeForce (0, 0, -2); }
if (Input.GetKey("d")) { rigidbody.AddRelativeTorque (0, 0, 2); rigidbody.AddRelativeForce (0, 0, 2); } }`
Try to use Camera.mainCamera Instead Camera.main.
I use Camera.mainCamera on my scripts.
This question is still unanswered. Can someone please help me out.
