Hopefully you are just busy And don't have time to make more videos yet. Because I don't want you to stop making these... They are super helpful and better then any others on YouTube. Never stop making these.. IWANTMORE!

[onestopprogramming]

@McNamarinara Yes. Very busy. Everytime I want to make an new tutorial something comes up. I'm crossing my fingers for this weekend.

So, lets say I have 5 different functions. Would it be better (RAM wise) to have a global "int num1 = 5;" Or have 5 local "int num1 = 5;" ?

[onestopprogramming]

@pong360ping Great question and the answer may surprise you. A global variable does not go away until the program exits because it is declared in the global scope so it exists everywhere and is always using RAM. Variables in functions however are only created when that function is called. When that function ends and reaches the return or } all the variables created in that function are destroyed.

also when if ever will u be covering random variables

[onestopprogramming]

@mrninja4273 I will be covering them soon.

I really hope you can make more soon. I've tried watching other tutorials and this one has been the most comprehensive so far.

I'm working my way through these lessons, and I hope you'll have more out soon, just because of how good you teach it : )

I love the fact that new coders aim high whilst still in early days. I remember when I had that kind of heady optimism. The main problem as a coder is the lack of graphic programmers. You need someone who is willing to produce some graphics (no small task!) for you to play with.

You'll be on the right path if you do a simply Snakes game in your first 4 years (as in get the time to do it not the ability) and remember that games take a huge amount of time to develop.

Thank you so much for making these videos! I really look forward to the game tutorials, will the game have graphics or is it going to be a text based game?
