[QUOTE=Darwin226;25830450]The only good feeling after making a successful program in an unmanaged language I'd get is because the language gave me more opportunities to screw up and I didn't.
The garbage collector for example. It takes care of memory management for you (for the most part).
Why do it yourself? You won't manage your memory that much better manually while there are infinite memory leak possibilities.[/QUOTE]
Actually if you're trying to code a pretty realtime application the gc sweeps are going to kill your loop timing. Is it every 250ms? I forgot. Managing your own memory can be beneficial. It [i]depends on the application's needs.[/i]. Or perhaps just your taste for the language. I havn't used C++ a lot but I've learned a lot of it, because that knowledge is useful sometimes, even if my main language is C#.

I finally got some form of a preprocessor working.

`foreach(var, list;of;stuff)
    ${var}
`endforeach

So I basically implemented CMake's language. :eng99:

That's not how mark & sweep works. No modern garbage collector initiates a mark & sweep at timed intervals, it sweeps on heap allocation if it decides that available heap memory is low. That means if you don't heap allocate in a performance critical loop, you won't trigger a sweep. This isn't as easy in Java and scripting languages, but in languages like C#, D and C++ (with the Hans Boehm GC, for example) it's easy to avoid heap allocation for specific sections. And in any language you can preallocate your memory (which is recommended for deterministic performance even without a GC) using stuff like free lists. If you're using GC in a language like C++ or D, you can also temporarily disable the GC and run the collect cycle later at an appropriately chosen time (this also allows for deterministic execution of finalizers). For example, with games it's a known trick to run the collect cycle before waiting for sync when that's enabled. In C#.NET, you can use GCLatencyMode.LowLatency (and other GCSettings) to achieve mostly the same results for critical sections.

Just because garbage collection has a runtime overhead doesn't mean it will always affect performance in your application. With a little bit of consideration, it's easy to write performant code running in a garbage collected runtime. If you're on a multi-core system, the CPU overhead in runtimes like .NET and JVM are even smaller because those garbage collectors are almost entirely concurrent.

pardon my pedantry, but I believe the unreal engine actually does use timed intervals. (Though it doesn't cover the whole memory tree, but rather as much as it can in a given frame of time (x), every (n) frames)

That's an example of invoking the garbage collection manually, the garbage collector won't interrupt the program at timed intervals to do a collection cycle.

That said I'd also like to note that one of the greatest misconceptions about managed languages is that you don't have to worry about memory. It's simply not true if you care about writing anything other than trivial, or pure trash slow horrible code. I personally worry about programmers who don't even at least basically understand the performance characteristics of whatever gc their host environment implements, and worry even more about those who wouldn't know that there is more than one type of gc.

I agree, if you want any kind of performance in a garbage collected environment, you still have to worry about managing memory. Of course, the upsides are still clear: you can manage memory only for your critical sections, while doing write-and-forget where it's not important. You usually also get a memory safe environment (.NET barring C#'s "unsafe", JVM, scripting languages etc) which can greatly reduce time spent on bugs like dangling pointers etc.

A lot of GC users in more conservative languages (I even talked to one who used it for his very large C application) tend to liken garbage collection to that of a safety net, I think that's a very sensible way of thinking about it.

I know it's not very programming related, but I think you should put more effort into the quality of your menus and visuals. Probably 10-20% of my programming time is spent repositioning, resizing, recolouring menu / gui / hud stuff. It makes such a difference in whether people will look at your game and think "That looks amature" and "That looks like he's put hours into it". People are shallow, remember that the face of the program is just as important as its brain.

For example here - the text fills the boxes and the boxes have no padding, and the text is really big. Also the positioning of the info box is top-center-right, which is kind of odd. Making proportions and positions feel "right" is important. The fact that all the name boxes are different widths looks unusual too to me.

I know it's sort of unrelated to the actual workings of your project, but attention to these little things makes all the difference IMO and it's what I always aim for before I release anything.

[cpp]
//bla bla bla code
// we're in the update() function

foreach (RedBall redBall in RedBalls) { //RedBall is my renderable object, RedBalls is my LinkedList
if (redBall.getPos().Y > 300) { //300 hardcoded for testing purposes atm
RedBalls.Remove(redBall);
}
redBall.Update(gameTime);
}

// bla bla bla more code
[/cpp]

Now, what this does, is complain that "Collection was modified after the enumerator was instantiated".
I know what it means, but can't figure how to solve it. Any ideas?

thanks for any help[/QUOTE]

In situations like this, I use an approach similar to the following:
[cpp]
//bla bla bla code
// we're in the update() function
for(int i = 0; i < RedBalls.Count(); i++)
{
if(RedBalls[i].getPos().Y > 300)
{
RedBalls.RemoveAt(i);
i--;
} else
RedBalls[i].Update(gameTime);
}
// bla bla bla more code
[/cpp]

You decrement to offset the fact that you just removed an element.

Of course you will need to adjust the iteration if it's a linked list and not a list.

With iterators, the erase method usually returns the next iterator so you can use that.

Yeah, I got confused by another article. Which is weird cause I knew that too. But either way, it's not going to work out unless you preallocate every byte of gc'd memory you use. You can't just hope the garbage collector won't take too long the next time you allocate. It'd be way easier to use a language meant for it.
