Constructor not needed?

I noticed that we created an Invader object in Game.cs, but we didn't have a constructor method in the Invader class in Invader.cs. Why is that that valid?

Thanks.

If you don't provide a constructor for a class, C# creates one by default that instantiates the object and sets member variables to their default values. This is known as the "default constructor" and it has no parameters.

It is not needed. Use constructor when you need it to pass in arguments.
