Small note: you’ll need
using Microsoft.Xna.Framework.GamerServices;
at the top of your file to use this code.

Helpful snippet. Thanks Nick!

I suspect that’s what they’re doing under the hood, too. I mean, there are only up to four local players, so it’s pretty simple to iterate through them to find the appropriate PlayerIndex. And I do understand the motivation behind making your code more verbose. Explicit == good when explaining stuff.

Ah yes you can. I always forget about that. I keep thinking that if controller 3 signs in they’ll be index 0, which they might be. But you are right; they have an overload that takes the PlayerIndex instead. Though, in essence, that’s likely what they’re doing under the hood. That or they really are sorting the gamers by index and then are just wrapping the cast to int in the PlayerIndex indexer.

I’ll just adjust the above code.

As for your other line, I’d personally use that, but I generally use more verbose code when doing samples. I find most people prefer it.

Can’t you just index into Gamer.SignedInGamers with a PlayerIndex without having to iterate through them?

SignedInGamer gamer = Gamer.SignedInGamers[player];
return gamer != null && gamer.IsSignedInToLive && gamer.Privileges.AllowPurchaseContent;
