Simple Character movement giving object error
Everything I've read says I'm doing this properly.. so I have no idea what I'm doing wrong. Its a simple move script. Press W and the camera moves forward. And I'm getting the following error.
CameraController.Update () (at Assets/Game/Scripts/Camera/CameraController.js:204) function Update () { var controller : CharacterController = GetComponent(CharacterController);NullReferenceException: Object reference not set to an instance of an object
if(Input.GetKey("w")) { moveDirection = Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical")); transform.Translate(moveDirection); moveDirection = speed;
// Move the controller controller.Move(moveDirection Time.deltaTime); }
if(Input.GetKey("s")) { moveDirection = Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical")); transform.Translate(moveDirection); moveDirection = speed;
// Move the controller controller.Move(moveDirection Time.deltaTime); }
if(Input.GetKey("a")) { moveDirection = Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical")); transform.Translate(moveDirection); moveDirection = speed;
// Move the controller controller.Move(moveDirection Time.deltaTime); }
if(Input.GetKey("d")) { moveDirection = Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical")); transform.Translate(moveDirection); moveDirection = speed;
// Move the controller controller.Move(moveDirection Time.deltaTime); }
if (Input.GetButtonDown("Fire2")) { mouseButton2DownPoint = Input.mousePosition; mouseRightDrag = true; }
if (Input.GetButtonUp("Fire2")) { mouseRightDrag = false; mouseButton2UpPoint = Input.mousePosition; }
if (Input.GetButtonDown("Fire3")) { print("Middle Mouse"); mouseButton3DownPoint = Input.mousePosition; mouseMiddleDrag = true; }
if (Input.GetButtonUp("Fire3")) { mouseMiddleDrag = false; mouseButton3UpPoint = Input.mousePosition; if (mouseButton3DownPoint == mouseButton3UpPoint) { ClearSelectedUnitsList(); } } } I was gonna remove all the charactercontroller code and instead use transform.position. But doing that gets me errors about not being able to convert vector 3 into a float. I'm confused here. My apologies.. the error is coming from "Controller.Move(moveDirection * Time.deltaTime);
We can´t know what´s your problem because we don´t know which line is the 204th. Edit your question with this info. An a way to find out which of the variables is null is to do the following, for example, if you haev the line
var1.var2.var3.DoSomething;
do this just above the line that throws the error
print("var1 = "+var1); print("var2 = "+var2); print("var3 = "+var3);
then you can see on your console windows exactly which of the terms is null
That's a very weird code! You must use character.Move (preferably) or transform.Translate, not both at the same time. And you don't need to check the keys WASD individually: Input.GetAxis does it at once for you. Your code could be as simple as this:
function Update () { var controller : CharacterController = GetComponent(CharacterController);
moveDirection = Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
moveDirection *= speed;
// Move the controller
controller.Move(moveDirection * Time.deltaTime);
if (Input.GetButtonDown("Fire2"))
{
mouseButton2DownPoint = Input.mousePosition;
mouseRightDrag = true;
}
if (Input.GetButtonUp("Fire2"))
{
mouseRightDrag = false;
mouseButton2UpPoint = Input.mousePosition;
}
if (Input.GetButtonDown("Fire3"))
{
print("Middle Mouse");
mouseButton3DownPoint = Input.mousePosition;
mouseMiddleDrag = true;
}
if (Input.GetButtonUp("Fire3"))
{
mouseMiddleDrag = false;
mouseButton3UpPoint = Input.mousePosition;
if (mouseButton3DownPoint == mouseButton3UpPoint) {
ClearSelectedUnitsList();
}
}
}
Aldo, unfortunately.. without get key its not picking up the key being pressed once so ever. I should add... the code WOR$$anonymous$$S.. it just produces that error on controller.$$anonymous$$ove whenever the key is pressed. And without transform.Traslate... it doesn't work at all.
Well, this should work, but I suppose that this error is preventing your script to work normally. If the error points to controller.$$anonymous$$ove, then probably the CharacterController isn't being found: you've forgot to add a CharacterController to your character, or it's added to an object and your script is attached to another one, possibly a child or parent - notice that the script and the CharacterController must be attached to the same object! Another possibility: the script was inadvertently attached to more than one object (again, probably a character child).
If you can't see any of these errors, add the following line to your script:
function Start(){
if (!GetComponent(CharacterController)){
print("CC not found - script attached to "+name);
}
}
Check if that damned button Collapse isn't active in the Console view, and click run: if the CharacterController isn't being found, the name of the object to which the script is attached will appear in the message, thus you can more easily know what's going wrong.
