Unity MouseWheel weapon change

Question

I am trying to make a simple weapon change in Unity3D. The best way to do this is with the mouse scroll wheel, as far as I can see.

I googled on how to do this and found that I have to use Input.GetAxis("Mouse ScrollWheel"); I use this piece of code and print it. Still, I always get an value of 0. any ideas? I just need to solve how to get the value first, I'll figure out the rest myself.

Code idea:

function Update () {
    print(WeaponNumber);

    if(Input.GetAxis("Mouse ScrollWheel")){
    WeaponNumber += Input.GetAxis("Mouse ScrollWheel");
    }
}

Answer 1

In addition to using the code you have above you need to configure the axis in the input manager and name it correctly.
