1,888 PointsLevel.cs: Invader.IsActive vs invaders.IsActive question
If I leave the code as is, 3 errors appear : The . name 'invaders' does not exist in current context. If I change the code to Invader then this error appears: An object reference is required to access non-static member TreehouseDefense.Invader.IsActive. Can you please explain why neither works and what do you recommend I do to address that.

231,198 Points"Invader" (capital "I") is a class, not an object; but "invader" (lower case "i") has not been created yet. And "invaders" (plural) is probably just a typo.
If you look at around 3:25 in the video Putting It All Together, you'll see that some of the code added at that point is missing from your file. And it's in that missing code where "invader" gets created.
