How to make a 2d mouse look script

Questions & Answers
1

Hello. I've been working on a 2d game, but I've run into a problem with a standard function. 1. How do you make a object rotate to face the cursor? and 2. How do you make the crosshair follow the mouse.

Thanks.

Try this answer. It should solve the 2D Rotation issue.

Considering you have a GUI Crosshair texture, here's the code you use.

var crosshairTexture : Texture2D;

var position : Rect;

function Start() { position = Rect( ( Screen.width - crosshairTexture.width ) / 2, ( Screen.height - crosshairTexture.height ) / 2, crosshairTexture.width, crosshairTexture.height ); }

function OnGUI() { GUI.DrawTexture(position, crosshairTexture);

}

...and that's how. about that 2d rotator thing... I absolutely have no idea. PS make sure to have the GUI Crosshair set into the script. remember, the script is in the camera!

public class MouseLook : MonoBehaviour

        MouseLook2D();
    }

    void MouseLook2D()
    {
        Vector3 mousePosition = Input.mousePosition;
        mousePosition = Camera.main.ScreenToWorldPoint(mousePosition);

        Vector2 direction = new Vector2(
            mousePosition.x - transform.position.x,
            mousePosition.y - transform.position.y
            );

        transform.up = direction;
    }
}
