Video camera moving glitch

Hi there! And welcome!

This is not really a video question. In Unity, video really refers to streaming of things like video files. Nevertheless, let's see if we can help.

So the problem has to do with what Input.GetAxis actually does. If you drop this code into your file, you'll see what I mean:

Code (CSharp):

1.     private void OnGUI()
2.     {
3.         float X = Input.GetAxis("Mouse X");//speedX * Input.GetAxis("Mouse X");
4.         float Y = Input.GetAxis("Mouse Y");//speedY * Input.GetAxis("Mouse Y");
5.         string msg = string.Format("{0}, {1}", X, Y);
6.         GUI.TextArea(new Rect(0f, 0f, 200f, 30f), msg);
7.     }
8.  

With that code running, you'll get a box showing the value of the input...you'll see that it pretty much always reverts to 0 if the mouse isn't moving. I suspect what you need is something to get distance from screen center. Something like:

Code (CSharp):

1. float X = Input.mousePosition.x - (Screen.width / 2f);
2. float Y = Input.mousePosition.y - (Screen.height / 2f);

With all that said, you might want to consider using Cinemachine...which is our solution for most camera purposes. There's a bit of a learning curve, but it'll serve you better in the long run.

 

Your code doesn't move the camera because the values always end up as zero.

Try replacing this in your code:

Code (CSharp):

1. float X = speedX * Input.GetAxis("Mouse X");
2. float Y = speedY * Input.GetAxis("Mouse Y");

with mine:

Code (CSharp):

1. float X = Input.mousePosition.x - (Screen.width / 2f);
2. float Y = Input.mousePosition.y - (Screen.height / 2f);

And see the difference.
