Rotate around vertically

Hello everyone,

I'm sure this is a simple fix that I'm too blind to see, but, I have a camera than I want to be able to pitch up and down, whilst looking at an object.

So, here is the code right now for the pitching.

Code (csharp):

1.  
2. Vector3 axis = new Vector3(Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y"), 0);
3.  
4. if (axis.y != 0)
5. {
6.     transform.RotateAround(new Vector3(0, 1, 0), Vector3.right, axis.y * camSpeed);
7. }
8.  

only issue is that it "sways" side to side and not up and down, no matter what I set. So, perhaps I'm just making a rookie mistake?

Cheers.

 

If I understood correctly you want to look at an object and be able to rotate around it on the camera Local X axis. If so then this works for me.

Code (csharp):

1. public class Look : MonoBehaviour {
2.    
3.     public GameObject targetObject;
4.     public float camSpeed = 1;
5.    
6.     // Use this for initialization
7.     void Start () {
8.         transform.LookAt(targetObject.transform.position);
9.     }
10.    
11.     // Update is called once per frame
12.     void Update () {
13.  
14.         float mouseY = camSpeed * Input.GetAxis("Mouse Y");
15.        
16.         if (targetObject != null)
17.         {              
18.             Vector3 localX = transform.TransformDirection(Vector3.right);
19.            
20.             transform.RotateAround(targetObject.transform.position, localX, mouseY);
21.         }
22.        
23.     }
24. }
25.  

 

This code gave back the exact same result, I wish for it to rotate vertically, and yet this code causes it to orbit elliptically up and down. Any idea why that is?

 

I'm a bit unclear on what you want. Because what I gave you will allow you to rotate the camera around a given object whilst looking at it. You said you want an camera that can "pitch up and down, whilst looking at an object". Do you mean you want a camera that elevates up in a straight line looking at the target but does not rotate about it?

Like this?

Code (csharp):

1. public class Look : MonoBehaviour {
2.    
3.     public GameObject targetObject;
4.     public float camSpeed = 15;
5.    
6.     // Use this for initialization
7.     void Start () {
8.         transform.LookAt(targetObject.transform.position);
9.     }
10.    
11.     // Update is called once per frame
12.     void Update () {
13.  
14.         float mouseY = camSpeed * Input.GetAxis("Mouse Y");
15.        
16.         if (targetObject != null)
17.         {              
18.             transform.Translate(new Vector3(0, mouseY, 0), Space.World);
19.             transform.LookAt(targetObject.transform.position);                  
20.         }
21.        
22.     }
23. }

 

Thanks! Works great.
