while(playerLives !=0 && alienShips !=0 ){

The above code says, keep looping all the time that both playerLives and alienShips are any value other than zero. Therefore if either(or perhaps even both simultaneously) playerLives or alienships becomes zero the loop will end.

I am not saying I am right I am just not able to see the error. This could be early onset Alzheimer’s, I do have memory problems already. I hope you don’t think I am being stubborn.

Thanks for taking the time.

Sorry, but correct me if I’m wrong but I think Lux comment that you should use the “||” operator is the right way to use in the example. If you are going for the condition of checking whether one condition would turn to false to end the loop the correct operator would be the “||”.

I also based this using the Psuedo Code style you mentioned in the previous chapters. I will quote the above comment “the loop will keep going until either the player “”OR”” the aliens have run out of lives/ships”. But again, correct me if I’m barking off the wrong tree.

Great tutorial by the way! keep it up!

Thanks for your message. The i is a variable. You can read about them here. I won’t be able to give you any tips on the other tutorial because I am not familiar with it, unfortunately. As to you other question, I don’t think there is any “best” language/platform/engine but there is usually one which is most appropriate for you and your situation. To try and work out what is right for you take a look at this where do I start tutorial.
