Trying to simply divide a value from a vector

I don't have internet right now so bear with me. I was reading a Reddit post by someone who replicated source engines 3d skyboxes. They said they "simply divided camera movement by a scale factor" to get a second camera to move and project what it sees. However when I try to do this I keep getting "operator / cannot be applied to operands of type 'void' and 'float'

My code looks like this:

Code (CSharp):

1. Public Gameobject targetcamera;
2. Public float ratio;
3.  
4. Void update(){
5. Float a = targetcamera.transform.translate(vector3.left) / ratio;

People keep saying that the vector3 returns floats, but that isn't enough info to help me

 

targetcamera.transform.translate(vector3.left) moves the transform by the given vector. it does not return a vector hence the 'void' in the error message.

 

So how could I make one to one movement? I tried using transform.position instead but now my object doesn't stop moving

 

Create a temporary vector and do you maths in that...

Code (CSharp):

1.     public Gameobject targetcamera;
2.     public float ratio;
3.     Vector3 displacement;
4.    
5.     void Update(){
6.         displacement = Vector3.left;
7.         displacement.x /= ratio;
8.         displacement.y /= ratio;
9.         displacement.z /= ratio;
10.  
11.         targetcamera.transform.translate(displacement);
12.     }
13.  

Although if you're just moving your camera left always, you can create a new vector to move by scaled by ratio.

Code (CSharp):

1.     public Gameobject targetcamera;
2.     public float ratio;
3.     Vector3 displacement;
4.      
5.     void Start(){
6.         displacement = new Vector3(-1/ratio, 0, 0);
7.     }
8.     void Update(){
9.         targetcamera.transform.translate(displacement);
10.     }
11.  

 

thanks, ill try it out
