Hello, I am trying to make a topdown shooter game, but my problem is that I can’t make the player rotate correctly.  
The main camera is following the player, but whenever the camera moves, this.input.mousePointer.worldX and worldY don’t update if I don’t move the pointer.  
So I searched for this problem and I saw that this.input.setPollAlways was used for this, but it doesn’t seem to work either. I would prefer a solution without locking the pointer and reticles.

Here’s the code:  
class GamePlay extends Phaser.Scene {

```
  constructor() {

    super({

      key: "GamePlay",

    });

    this.speed = 400;

    this.w = 3200;

    this.h = 2400;

  }

  preload() {}

  create() {

    this.background = this.add.image(this.w / 2, this.h / 2, "background");

    this.player = this.physics.add.sprite(this.w / 2, this.h / 2, "player");

    this.player.setScale(0.25).setCollideWorldBounds();

    this.physics.world.setBounds(0, 0, this.w, this.h);

    this.cameras.main.zoom = 0.5;

    this.cameras.main.startFollow(this.player, true);

    this.cameras.main.setBounds(0, 0, this.w, this.h);

    this.input.setPollAlways();

    this.txt = this.add.text(

      this.cameras.main.scrollX,

      this.cameras.main.scrollY,

      "h ", {

        font: "25px Arial",

        fill: "yellow",

      }

    );

    this.moveKeys = this.input.keyboard.addKeys({

      up: Phaser.Input.Keyboard.KeyCodes.W,

      down: Phaser.Input.Keyboard.KeyCodes.S,

      left: Phaser.Input.Keyboard.KeyCodes.A,

      right: Phaser.Input.Keyboard.KeyCodes.D,

    });

    this.input.keyboard.on("keydown_W", (e) => {

      this.player.setVelocityY(-this.speed);

    });

    this.input.keyboard.on("keydown_S", (e) => {

      this.player.setVelocityY(this.speed);

    });

    this.input.keyboard.on("keydown_A", (e) => {

      this.player.setVelocityX(-this.speed);

    });

    this.input.keyboard.on("keydown_D", (e) => {

      this.player.setVelocityX(this.speed);

    });

    this.input.keyboard.on("keyup_W", (e) => {

      if (this.moveKeys["down"].isUp) {

        this.player.setVelocityY(0);

      }

    });

    this.input.keyboard.on("keyup_S", (e) => {

      if (this.moveKeys["up"].isUp) {

        this.player.setVelocityY(0);

      }

    });

    this.input.keyboard.on("keyup_A", (e) => {

      if (this.moveKeys["right"].isUp) {

        this.player.setVelocityX(0);

      }

    });

    this.input.keyboard.on("keyup_D", (e) => {

      if (this.moveKeys["left"].isUp) {

        this.player.setVelocityX(0);

      }

    });

  }

  update(time, delta) {

    this.player.rotation = Phaser.Math.Angle.Between(

      this.player.x,

      this.player.y,

      this.input.mousePointer.worldX, this.input.mousePointer.worldY

    );

    this.txt.text = this.input.mousePointer.worldX + ", " + this.input.mousePointer.worldY;

    this.txt.setPosition(this.cameras.main.scrollX, this.cameras.main.scrollY);

  }

}
```

What are you trying to do? If you are trying to get a reticle, there is an example for that but here is how I would do it using event listeners:

```javascript
this.input.on('pointermove', function(pointer) {
  reticle.x = pointer.x + this.cameras.main.scrollX;
  reticle.y = pointer.y + this.cameras.main.scrollY;
});

```

Thats the thing, I don’t want reticles

Oh sorry. Do you just want to get the position of the mouse?

somewhere in global scope:

```javascript
var mouseX = 0;
var mouseY = 0;

```

In create():

```javascript
this.input.on('pointermove', function(pointer) {
  mouseX = pointer.x + this.cameras.main.scrollX;
  mouseY = pointer.y + this.cameras.main.scrollY;
});

```

If you wanted a more “right” way to do this then you can use vectors but they are a little difficult to wrap your head around if you’re a beginner.  
somewhere in global scope:

```javascript
vec2 mouse = (0,0)

```

In create():

```javascript
this.input.on('pointermove', function(pointer) {
  mouse.x = pointer.x + this.cameras.main.scrollX;
  mouse.y = pointer.y + this.cameras.main.scrollY;
});

```

And then you can just refer to it using .x and .y.

Unfortunately, it has the same result. It works okay when you constantly move the mouse, but when you don’t and just move the camera, the x, y of the pointer don’t refresh.

Ohhhhh. Yeah that totally makes sense. Sorry I misunderstood a little.

Put

```javascript
mouse.x = pointer.x + this.cameras.main.scrollX;
mouse.y = pointer.y + this.cameras.main.scrollY;

```

somewhere inside your update() function, and get rid of the mouse move listener. That’s my bad.

This answer assumes your using the vector approach, here is it without that:

```javascript
mouseX = pointer.x + this.cameras.main.scrollX;
mouseY = pointer.y + this.cameras.main.scrollY;

```

Where do i get the pointer.x and pointer.y from then?

You should be access the variable(s) from anywhere if you declared it globally.  
You can declare it globally by putting it in a script tag in your html. e.g.

```javascript
// index.html
<script>var mouseX; varMouseY;</script>

```

yes that’s the mouseX, mouseY but what about the pointer.x in this "mouseX = **pointer.x** + this.cameras.main.scrollX

</div>

declare `var pointer` in global scope and then in create() use this:

```javascript
pointer = this.input.activePointer;

```

was just about to say that I got it… thank you, it works

in update()

```
  this.mouseX = this.input.mousePointer.x + this.cameras.main.scrollX;
  this.mouseY = this.input.mousePointer.y + this.cameras.main.scrollY;
  this.player.rotation = Phaser.Math.Angle.Between(
    this.player.x,
    this.player.y,
    this.mouseX, this.mouseY
  );
```
