Attaching CharacterController

Questions & Answers
1

Hi,

I am new in Unity (I’m C# developer).

I created a cube (named Player). I attached it a 3rd Person CharacterController by importing the CharecterController Asset and drag-and-dropping the 3rd person CC icon from project-> StandardAsset to the Hierarchy->Player. In the script I have the line:

this.GetComponent ().Move (displacement);

But after change to Game and press Play, in the console I have the message:

MissingComponentException: There is no ‘CharacterController’ attached to the “Player1” game object, but a script is trying to access it.

I don’t know how to solve it. Please, could you help me ?

Click your cube called “Player1” in the scene. Make sure it’s not just his parent/child object. Now when the game runs, check to see if the script is enabled. If it is not, you may have a script that disables it at runtime.

Thanks. In the script I have a public variable (moveSpeed) that is set to 100.0f.
When I press play in Game, this variable drops down to zero, but in scene is correct, i.e. 100. I guess this is the cause, but I don’t know how to set it back to 100. In fact I have two scripts. First is GameCam.cs and is attached to MainCamera:

using UnityEngine;
using System.Collections;

public class GameCam : MonoBehaviour {
public GameObject trackObj;
public float height;
public float desiredDistance;
public float heightDamp;
public float rotDamp;
// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
	UpdateRotAndTrans ();
}

void UpdateRotAndTrans(){
	float DesiredRotationAngle;
	float DesiredHeight;

	if (trackObj) {
		DesiredRotationAngle = trackObj.transform.eulerAngles.y;
		DesiredHeight = trackObj.transform.position.y + height;
		float RotAngle = transform.eulerAngles.y;
		float Height = transform.position.y;
		RotAngle = Mathf.LerpAngle(RotAngle, DesiredRotationAngle, rotDamp);
		Height = Mathf.Lerp(Height, DesiredHeight, heightDamp*Time.deltaTime);
		Quaternion CurrentRotation = Quaternion.Euler(0.0f, RotAngle, 0.0f);
		Vector3 pos = trackObj.transform.position;
		pos -= CurrentRotation * Vector3.forward * desiredDistance;
		pos.y = Height;
		transform.position = pos;
		transform.LookAt(trackObj.transform.position);
	} else {
		Debug.Log ("Game Camera: Error, trackObj invalid !");
	}
}

 }

The second (where is the line I mentioned) is PlayerControls.cs:

 using UnityEngine;
 using System.Collections;

 public class PlayerControls : MonoBehaviour {
Vector3 moveDirection = Vector3.zero;
public float rotateSpeed;
public float moveSpeed = 100.0f;
public float speedSmoothing = 10.0f;
// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
	UpdateMovement ();
}

void UpdateMovement(){
	Vector3 cameraForward = Camera.mainCamera.transform.TransformDirection (Vector3.forward);
	cameraForward.y = 0.0f;
	cameraForward.Normalize ();
	Vector3 cameraRight = new Vector3 (cameraForward.z, 0.0f, -cameraForward.x);
	float v = Input.GetAxisRaw ("Vertical");
	float h = Input.GetAxisRaw ("Horizontal");
	Vector3 targetDirection = h * cameraRight + v * cameraForward;
	moveDirection = Vector3.RotateTowards (moveDirection, targetDirection, rotateSpeed * Mathf.Deg2Rad * Time.deltaTime, 1000);
	moveDirection = moveDirection.normalized;
	float curSmooth = speedSmoothing * Time.deltaTime;
	float targetSpeed = Mathf.Min (targetDirection.magnitude, 1.0f);
	moveSpeed = Mathf.Lerp (moveSpeed, targetSpeed, curSmooth);
	Vector3 displacement = moveDirection * moveSpeed * Time.deltaTime;
	this.GetComponent<CharacterController> ().Move (displacement);
	transform.rotation = Quaternion.LookRotation (moveDirection);
}
}
