Lock mouse in center of screen, and still use to move camera Unity
- by Flotolk
I am making a program from 1st person point of view. I would like the camera to be moved using the mouse, preferably using simple code, like from XNA
var center = this.Window.ClientBounds;
MouseState newState = Mouse.GetState();
if (Keyboard.GetState().IsKeyUp(Keys.Escape))
{
Mouse.SetPosition((int)center.X, (int)center.Y);
camera.Rotation -= (newState.X - center.X) * 0.005f;
camera.UpDown += (newState.Y - center.Y) * 0.005f;
}
Is there any code that lets me do this in Unity, since Unity does not support XNA, I need a new library to use, and a new way to collect this input.
this is also a little tougher, since I want one object to go up and down based on if you move it the mouse up and down, and another object to be the one turning left and right.
I am also very concerned about clamping the mouse to the center of the screen, since you will be selecting items, and it is easiest to have a simple cross-hairs in the center of the screen for this purpose.
Here is the code I am using to move right now:
using UnityEngine;
using System.Collections;
[AddComponentMenu("Camera-Control/Mouse Look")]
public class MouseLook : MonoBehaviour {
public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 }
public RotationAxes axes = RotationAxes.MouseXAndY;
public float sensitivityX = 15F;
public float sensitivityY = 15F;
public float minimumX = -360F;
public float maximumX = 360F;
public float minimumY = -60F;
public float maximumY = 60F;
float rotationY = 0F;
void Update ()
{
if (axes == RotationAxes.MouseXAndY)
{
float rotationX = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * sensitivityX;
rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);
transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0);
}
else if (axes == RotationAxes.MouseX)
{
transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityX, 0);
}
else
{
rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);
transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0);
}
while (Input.GetKeyDown(KeyCode.Space) == true)
{
Screen.lockCursor = true;
}
}
void Start ()
{
// Make the rigid body not change rotation
if (GetComponent<Rigidbody>())
GetComponent<Rigidbody>().freezeRotation = true;
}
}
This code does everything except lock the mouse to the center of the screen. Screen.lockCursor = true; does not work though, since then the camera no longer moves, and the cursor does not allow you to click anything else either.
