Why do Do-While Loops Exist?

esotericdrabbles answered your question: Anybody have a coding-related problem I can help with?
why do them do-loops exist i dont want them anymore

It’s actually pretty simple~!

  • Normal while-loops check the condition before ever running.
  • Do-while loops check after running, meaning that the loop will run at least once.

I’ve never had to use it, myself. Here’s my attempt at an example:

So you’ve got a game. It’s got a timer; and once that timer hits zero, the game exits. Let’s say that something craps out, and you’re in the game before setting the timer: say this is a problem, because the game checks for player-connections and reports on ‘em. If the game just clocks out without doing the checks, everybody’ll be reported as rage-quitting! You wanna ensure that people are registered as properly connected, so a do-while loop would be preferred.

There are better ways around that particular problem, but hey. Do-while loops are a lot like exclusive-or, in that they’re real purpose is to just prove how clever you are.

Hope that all helps!

Q:Ooh! OohOohOoh!! Mememe!!! *raises hand* Why don't you start using Unity3d with the big boys like me? ouo

My current projects are about more than just a finished product. They are about fixing long-standing problems in the artistic, cultural, and industrial facets of video gaming. No engine provides a data-management system on par with Blender, and that is absolutely the most critical component to my entire plan.

In the future, with other games that have different goals, I have no qualms whatsoever using tools I’m not using now: those tools just don’t help with what I am trying to do right now.

Q:What exactly is it that you do? I know from looking at your blog that you make video games, but do you work for a company or by yourself? How hard is it to learn how to program video games (because it looks really hard)? Do you ever plan to use source filmmarker?

I’m kicking off a graphics-design career, apparently. I have no day job. In the near future, I’ll be taking up video-editing and whatever it’s called when you start doing YouTube as a thing.

Learning “how to program video games” is excruciatingly difficult, unless you learn the more important skill of “how to order your thoughts.” What kind of game are you making? How do you want it to be played? How much time do you have to work on it? How do you convey your own thoughts? If you don’t know how to answer those questions, making video games will be tough. If you don’t know how to ask those questions, making video games will be impossible.

I see the value in SFM, but I see myself hiring someone else to use it before I would.
