How to change the input action being used according to an int variable?

I want to use a vector 2 input action to be changed according to a int variable that is picked at random between 1 and 4. I know how to randomise the variable but do not know how to change the input action being used accordingly. I have created a input action called move and I want to assign one of four vector 2 input actions to it based on the randomised variable.

Switch statement is probably your best bet.

    int randomInt = Random.Range(1,4);
    Vector2 inputVector;
    switch(randomInt)
    {
        case 1:
            inputVector= new Vector2(0,0);
            break;
        case 2:
            inputVector= new Vector2(1,0);
            break;    
        case 3:
            inputVector= new Vector2(0,1);
            break;   
        case 4:
            inputVector= new Vector2(1,1);
            break;
        default:
            inputVector= new Vector2(0,0);

}
