Passing a function as an argument in C#

I’m trying to pass a function as an argument just like this:

void AvoidSpawn(float sRate, function f) 
    {
        float calculateRate = 0;
        if(Time.time>=calculateRate)
        {
            f();
            calculateRate = Time.time + spawnRate;
        }
    }

I don’t know how to use a function as an argument and pass it and I would like to replace function f with something that works.

>Solution :

For a function that doesn’t return any value (a void method), there are various Action delegates.

For a function that does return a value, you need Func and friends.

There are various versions to account for a number of parameters (up to 16, nowadays).

So you can define your function as

void AvoidSpawn(float sRate, Action f) 
{
   // ...
   f();
   // ...
}

And either call it with a lambda:

AvoidSpawn(1.0f, () => Console.WriteLine("Avoiding spawn"));

or mention another method

AvoidSpawn(1.0f, SomeVoidMethod);

Note: do not use () there, you don’t want to call that method yet.
