How can you use optional parameters in C#?

I am making text adventure, and using some code I found online, I have typewriter style printing. So I have this code in a function and besides passing in the code to type, I am also trying to pass in the delay between types. Now my problem is that I don’t always want to have to put in the argument for the delay, I tried searching the default value of a int variable and seeing if making a if statement check if the variable was not its default and if it wasn’t the default it would use what was passed in. Except it still won’t work, it still wants me to pass in something. Is their anyway to get this to work?

Sorry if my question is confusing, I’m not the best at making non-confusing sentences… (see?)

You can use Optional Arguments:

public void MovePerson(int x, int y, int delay = 300) 
{

}

Here, in this completely made up funciton, you can build in a default delay that will be set to 300 if you don’t specify a value when calling the function.

MovePerson(10, 20);  //Delay for 300
MovePerson(10, 20, 100); //Delay for 100
