2D Mouse and Right analog as Direction for the flashlight.
I am trying to make a flashlight facing a direction pointed by analog or mouse.
Here is my code for the playercontroller:
using UnityEngine;
using System.Collections;
public class PlayerController : MonoBehaviour {
public float speed;
public Animator anim;
// Use this for initialization
void Start () {
anim = GetComponent<Animator>();
}
void Update (){
float input_x = Input.GetAxisRaw ("Horizontal");
float input_y = Input.GetAxisRaw ("Vertical");
bool isWalking = (Mathf.Abs (input_x) + Mathf.Abs (input_y)) > 0;
anim.SetBool ("isWalking", isWalking);
if (isWalking) {
anim.SetFloat ("x", input_x);
anim.SetFloat ("y", input_y);
transform.position += new Vector3 (input_x, input_y, 0).normalized * Time.deltaTime;
}
}
}
And here is my code for flashlight:
void Update () {
if (Input.GetAxis ("Horizontal") > 0) {
transform.localEulerAngles = new Vector3 (0, 70, 0);
}
if (Input.GetAxis ("Horizontal") < 0) {
transform.localEulerAngles = new Vector3 (0, 290, 0);
}
if (Input.GetAxis ("Vertical") > 0) {
transform.localEulerAngles = new Vector3 (290, 0, 0);
}
if (Input.GetAxis ("Vertical") < 0) {
transform.localEulerAngles = new Vector3 (70, 0, 0);
}
}
I think i have to make my flashlight look at mouse by this code:
Vector3 mouseScreen = Input.mousePosition;
Vector3 mouse = mainCam.ScreenToWorldPoint(mouseScreen);
transform.rotation = Quaternion.Euler(320, Mathf.Atan2(mouse.y - transform.position.y, mouse.x - transform.position.x) * Mathf.Rad2Deg - 90, 0);
And when its rotating Y by 10 it has to be rotating X by 10 too.
You're using the same Axis calls for your flashlight direction as you are for movement.

That should get you pointed in the right direction. You'll need to define your own axes which make use of a right Analog Stick and Mouse inputs together.
Additionally, because you're only pointing in strict 90-degree-rotated directions (assuming that's the intent), you would also want to determine the greatest input of those with a small Dead Zone as a buffer.
If you're looking for precise aim for an alternative for mouse control, you will want to point in the direction of either the mouse cursor's position on screen (translated into a generalized world position) or the destination of a raycast from the mouse's position.
One other note: 0, 90, 180, 270. Your flashlight is currently set to face at a few odd angles, where it would be better to give it an empty parent, point the flashlight itself upward, then rotate around only the Z axis, rather than rotating it to up/down/left/right from forward. Then you can use 0, 90, 180, and 270 degree rotations instead.
