Rotate Camera with just axis X and Y

Questions & Answers
1

Hello I am new with Unity and forum so be patient.

I have some basic programming concepts before beginning with this.

I want to do a Camera Mouse Controller. I was seeing some script and the most undestandable for me is one from official Unity API (Unity - Scripting API: Input.GetAxis).

transform.Rotate(v, h, 0);

Where V, axis Y and H axis X.

How ever, this wont work well. It moves X and Y right, but a strange problem. It seems to rotate at it’s own or something like that.

0 stands for Angle Z, but I dont need a Z Angle I don’t have one in the mouse, cause it’s bidimensional.

If i give a different value to Z it starts to rotate without interaction.

What shall I Do?

Sorry about my English.

Thanks for listening to me.

Personally I don’t use Rotate, I use EulerAngles (basically converts vecter3 to quaternion).

transform.rotation *= Quaternion.EulerAngles (v, h, 0);

For whatever reason, in the world of Quaternions you multiply to add, divide to subtract. The code above adds v and h to transform.rotation.
Hope this helps!
