Question by Dartmor · May 31, 2015 at 12:24 AM · vector3changedegreesperpendicular

How to change Vector3 movement by degrees/to a perpendicular axis?

For example, i have this:

 GetComponent<ConstantForce>().force = new Vector3 (Input.GetAxis("Mouse X") * speed, 0f,Input.GetAxis("Mouse Y") * speed);

If i want to REVERT vectors, i simply need to do that:

 GetComponent<ConstantForce>().force = new Vector3 (-Input.GetAxis("Mouse X") * speed, 0f,-Input.GetAxis("Mouse Y") * speed);

Right? But what if i want not to revert it, but change it by degrees? Or for example, instead of moving by existing vector, it should move by a PERPENDICULAR vector to the exisiting one.

How to perform it? Or am i limited only by reversing current axis?

What i really need is to replace movement toward Vector3.zero by perpendicular vector.

 if (transform.position = Vector3.$$anonymous$$oveTowards(transform.position, Vector3.zero, Time.deltaTime)){
             move by perpendicular vector ins$$anonymous$$d
             }

I've actually created this perpendilar Vector3, it's called "NewVector", but i don't know where to use it
