Character Controls like the game "Fable"

Question

these are my current Character Controls

 //moving around
 var speed : float = 15.0;
 var rotateSpeed : float = 3.0;
 
 //shooting
 var bulletPrefab:Transform;
 
 //dying
 static var dead = false;
 
 //getting hit
 var tumbleSpeed = 800;
 var decreaseTime = 0.01;
 var decayTime = 0.01;
 static var gotHit = false;
 private var backup = [tumbleSpeed, decreaseTime, decayTime];
 
 function LateUpdate()
 {
     if(dead)
     {
         transform.position = Vector3(-40,4,0);
         gameObject.Find("Main Camera").transform.position = Vector3(-40,4,0);
         dead = false;
     }
     
     if(gotHit)
     {
         if(tumbleSpeed < 1)
         {
             //we're not hit anymore ... reset and get back into the game
             tumbleSpeed = backup[0];
             decreaseTime = backup[1];
             decayTime = backup[2];
             gotHit = false;
         }
         else
         {
             //we're hit.. spin character around
             transform.Rotate(0,tumbleSpeed*Time.deltaTime,0,Space.World);
             tumbleSpeed = tumbleSpeed - decreaseTime;
             decreaseTime += decayTime;
         }
     }
 }
 
 //function OnControllerColliderHit(hit : ControllerColliderHit)//onTriggerEnter | collider
 function OnTriggerEnter( hit : Collider )
 {
     if(hit.gameObject.tag == "fallout")
     {
         dead = true;
         //subtract life here
         HealthControl.LIVES -= 1;
     }
     
     if(hit.gameObject.tag == "enemyProjectile")
     {
         gotHit = true;
         HealthControl.HITS += 1;
         Destroy(hit.gameObject);
     }
 }
 
 function Update ()
  {
     var controller : CharacterController = GetComponent(CharacterController);
 
     // Rotate around y - axis
     transform.Rotate(0, Input.GetAxis ("Horizontal") * rotateSpeed, 0);
     
     // Move forward / backward
     var forward : Vector3 = transform.TransformDirection(Vector3.forward);
     var curSpeed : float = speed * Input.GetAxis ("Vertical");
     
     controller.SimpleMove(forward * curSpeed);
     
     if(Input.GetButtonDown("Fire1"))
     {
         var bullet = Instantiate(bulletPrefab,
                                 transform.Find("spawnPoint").transform.position,
                                 transform.rotation);
         bullet.tag = "playerProjectile";
         bullet.rigidbody.AddForce(transform.forward * 6000);

I still have no clue what a 'Fable' camera is, but decided to make a basic player controller. The character moves with WASD or arrow keys, to turn the character 180 degrees, press Q. The mouse horizontal rotates the character. Check the screenshot for the hierarchy on the gameObjects, follow the instructions on setting up an empty gameObject that will be the camera's position.

Create a basic scene, attach the below script to the Player Character

how to set up the CameraHolder object used in the script :

set the camera in the desired position
create an empty gameObject, name it CameraHolder
make the empty CameraHolder a child of the camera
set the Transform andd Rotation of CameraHolder to 0 in the Inspector
Now drag CameraHolder out of the camera and make it a child of the Player Character
CameraHolder is now set in the correct position

Here is the Script :

 #pragma strict
 
 public var theCamera : Transform;
 
 private var movementSpeed : float = 5.0;
 private var rotationSpeed : float = 5.0;
 private var currentRotation : float = 0.0;
 
 private var myTransform : Transform;
 private var cameraHolder : Transform;
 
 
 function Start() 
 {
     myTransform = this.transform;
     cameraHolder = transform.Find( "CameraHolder" );
 }
 
 function Update() 
 {
     // get inputs
     var inputX : float = Input.GetAxis( "Horizontal" );
     var inputY : float = Input.GetAxis( "Vertical" );
     var inputR : float = Mathf.Clamp( Input.GetAxis( "Mouse X" ), -1.0, 1.0 );
     // press 'Q' to turn 180 degrees
     if ( Input.GetKeyDown(KeyCode.Q) )
     {
         currentRotation += 180.0;
     }
     
     // get current position and rotation, then do calculations
     // position
     var moveVectorX : Vector3 = myTransform.forward * inputY;
     var moveVectorY : Vector3 = myTransform.right * inputX;
     var moveVector : Vector3 = ( moveVectorX + moveVectorY ).normalized * movementSpeed * Time.deltaTime;
     
     // rotation
     currentRotation = ClampAngle( currentRotation + ( inputR * rotationSpeed ) );
     var rotationAngle : Quaternion = Quaternion.Euler( 0.0, currentRotation, 0.0 );
     
     // update Character position and rotation
     myTransform.position = myTransform.position + moveVector;
     myTransform.rotation = rotationAngle;
     
     // update Camera position and rotation
     theCamera.position = cameraHolder.position;
     theCamera.rotation = cameraHolder.rotation;
 }
 
 
 function ClampAngle( theAngle : float ) : float 
 {
     if ( theAngle < -360.0 )
     {
         theAngle += 360.0;
     }
     else if ( theAngle > 360.0 )
     {
         theAngle -= 360.0;
     }
     
     return theAngle;
 }

Hello. Did this script work, or did you find the suggestion useful? Please post a comment or mark an answer, for future reference by other people searching this 'site.

This is the usual answer for questions like this, so I think this script is a bonus : http://answers.unity3d.com/questions/309842/dungeon-defenders-camera-and-control.html

@jay $$anonymous$$ay thanks, I have tried this but 1) i get the error at the bottom. 2) the capsule doesnt move with the camera

NullReferenceException UnityEngine.Transform.get_position () (at C:/BuildAgent/work/d9c061b1c154f5ae/Runtime/ExportGenerated/Editor/UnityEngineTransform.cs:19) NewChar.Update () (at Assets/$$anonymous$$yStuff/1$$anonymous$$yScripts/NewChar.js:46)

The script goes on the player. $$anonymous$$ake sure you have dropped the camera into theCamera in the inspector.

I have made a package you can import and check how I have set it up : http://www.alucardj.net16.net/unityanswers/FableChar.unitypackage

In Unity, browse to Assets > Import Package > Custom Package , then locate where you downloaded the package.

Change the Update to this :

 function Update() 
 {
     // get inputs
     var inputX : float = Input.GetAxis( "Horizontal" );
     var inputY : float = Input.GetAxis( "Vertical" );
     
     // get current position, then do calculations
     var moveVectorX : Vector3 = theCamera.forward * inputY;
     var moveVectorY : Vector3 = theCamera.right * inputX;
     var moveVector : Vector3 = ( moveVectorX + moveVectorY ).normalized * movementSpeed * Time.deltaTime;
     
     
     // update Character position
     myTransform.position = myTransform.position + Vector3( moveVector.x, 0.0, moveVector.z );
     
     // and rotation
     myTransform.LookAt( myTransform.position + Vector3( moveVector.x, 0.0, moveVector.z ) );
     
     
     // Firing
     if ( Input.GetButtonDown("Fire1") )
     {
         var bullet = Instantiate( bulletPrefab, transform.Find("spawnPoint").transform.position, transform.rotation );
         bullet.tag = "playerProjectile";
         bullet.rigidbody.AddForce( transform.forward * 6000 );
     }
     
 }

remove : @script RequireComponent(CharacterController)

in if (dead) , you now have a reference to the main camera, so change that line to :

 theCamera.position = Vector3(-40,4,0);

But this camera part may be overriden by the commands driving the camera. And the tumbling part I am worried about the char breaking. If you store the rotation before tumbling, then when respawning just use that rotation and give it back to the char.

Oops, don't forget to add this :

 public var theCamera : Transform;
 public var movementSpeed : float = 8.0;
 private var myTransform : Transform;
 
 function Start() 
 {
     myTransform = this.transform;
 }
 
 function ClampAngle( theAngle : float ) : float 
 {
     if ( theAngle < -360.0 )
     {
         theAngle += 360.0;
     }
     else if ( theAngle > 360.0 )
     {
         theAngle -= 360.0;
     }
     
     return theAngle;
 }
