Keyboard arrows turn around

Questions & Answers
1

Hi I am using First Person Control, I disabled MouseLook, so I can only control the game by keyboard arrows.But the arrows can only go forward/backward/right/left, I cannot turn around. I want when I press the right arrow, I will turn 45 degrees or 90 degrees, then I can use the up arrow to move forward. How can I do this?

Thanks

In FPSInputController.js, the line

var directionVector = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));

controls your movement on the x-axis/sideways (horizontal input keys) and z-axis/in&out (vertical input keys). If you remove 'Input.GetAxis("Horizontal")' you'll no longer be able to strafe. You can add a line right after it to rotate you along the y-axis based on the horizontal input keys:

transform.Rotate(Vector3.up, Input.GetAxix("Horizontal") * rotationSpeed * Time.deltaTime);

Hi Lucy and Scribe,

I have been reading your post an the indications from Scribe and finally got it work!

As I couldn’t attach the file, below you’ll find the complete code.

Regards,

German

private var motor : CharacterMotor;

// Use this for initialization
function Awake () {
	motor = GetComponent(CharacterMotor);
}

// Update is called once per frame
function Update () {
	// Get the input vector from kayboard or analog stick
	//var directionVector = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical")); Línea Original
	var directionVector = new Vector3(0, Input.GetAxis("Vertical"));
	transform.Rotate(Vector3.up, Input.GetAxis("Horizontal") * 0 * Time.deltaTime); //Linea Adicional
	if (Input.GetKey(KeyCode.DownArrow)) transform.Translate(0, 0, -1* Time.deltaTime);//Lineas para otro script?
	if (Input.GetKey(KeyCode.UpArrow)) transform.Translate(0, 0, 1* Time.deltaTime);
	if (Input.GetKey(KeyCode.RightArrow)) transform.Rotate(0, 1, 0);
	if (Input.GetKey(KeyCode.LeftArrow)) transform.Rotate(0, -1, 0);//Termina la Modificación


	
	if (directionVector != Vector3.zero) {
		// Get the length of the directon vector and then normalize it
		// Dividing by the length is cheaper than normalizing when we already have the length anyway
		var directionLength = directionVector.magnitude;
		directionVector = directionVector / directionLength;
		
		// Make sure the length is no bigger than 1
		directionLength = Mathf.Min(1, directionLength);
		
		// Make the input vector more sensitive towards the extremes and less sensitive in the middle
		// This makes it easier to control slow speeds when using analog sticks
		directionLength = directionLength * directionLength;
		
		// Multiply the normalized direction vector by the modified length
		directionVector = directionVector * directionLength;
	}
	
	// Apply the direction to the CharacterMotor
	motor.inputMoveDirection = transform.rotation * directionVector;
	motor.inputJump = Input.GetButton("Jump");
}

// Require a character controller to be attached to the same game object
@script RequireComponent (CharacterMotor)
@script AddComponentMenu ("Character/FPS Input Controller")

function Update () {

if (Input.GetKey(KeyCode.UpArrow)) transform.Translate(Vector3.forward * Time.deltaTime);

if (Input.GetKey(KeyCode.DownArrow)) transform.Translate(-Vector3.forward * Time.deltaTime);

if (Input.GetKey(KeyCode.RightArrow)) transform.Rotate(0, 1, 0);

if (Input.GetKey(KeyCode.LeftArrow)) transform.Rotate(0, -1, 0);

}

I leave here prepared to change the speed of movement and rotation in C#

public class FPSInputController : MonoBehaviour
{
private CharacterMotor motor;

public float rotationSpeed = 20.0f;
public float speed = 10.0f;


void Awake()
{
    motor = GetComponent<CharacterMotor>();
}

void Update()
{
	Vector3 directionVector = new Vector3(0, Input.GetAxis("Vertical"));

	transform.Rotate(Vector3.up, Input.GetAxis("Horizontal") * rotationSpeed * Time.deltaTime);

	if (Input.GetKey(KeyCode.DownArrow) || Input.GetKey(KeyCode.S)){ 
		transform.Translate(0, 0, -1* speed * Time.deltaTime);
	}

	if (Input.GetKey (KeyCode.UpArrow) || Input.GetKey(KeyCode.W)) {
		transform.Translate (0, 0, 1 * speed * Time.deltaTime);
	}

	if (Input.GetKey(KeyCode.RightArrow)|| Input.GetKey(KeyCode.D)) {
		transform.Rotate(0, 1, 0);
	}

	if (Input.GetKey (KeyCode.LeftArrow)|| Input.GetKey(KeyCode.A)) {
		transform.Rotate(0, -1, 0);
	}
	
	
	
	if (directionVector != Vector3.zero) {
		// Get the length of the directon vector and then normalize it
		// Dividing by the length is cheaper than normalizing when we already have the length anyway
		float directionLength = directionVector.magnitude;
		directionVector = directionVector / directionLength;
		
		// Make sure the length is no bigger than 1
		directionLength = Mathf.Min(1, directionLength);
		
		// Make the input vector more sensitive towards the extremes and less sensitive in the middle
		// This makes it easier to control slow speeds when using analog sticks
		directionLength = directionLength * directionLength;
		
		// Multiply the normalized direction vector by the modified length
		directionVector = directionVector * directionLength;
	}
	
	// Apply the direction to the CharacterMotor
	motor.inputMoveDirection = transform.rotation * directionVector;
	motor.inputJump = Input.GetButton("Jump");
}
