how to initialize a function

Unity Engine

How do you start a void that contains parameters inside?

    void Start()
    {
    myvoid();//this does not work, only with void without parameter
    }
    void myvoid(int parameter)
    {

What exactly is your question?

If you don’t want myvoid to accept a parameter, remove the parameter from its declaration.

If you want it to accept a default argument, specify the default value in the function declaration.

Otherwise, give it a parameter when you call it.

void Start()
{
   myVoid(3);
}
