Two Classes: GUILetter and GUIWord.
GUILetter is a single char letter. It has a location and a color.
GUIWord is a List<GUILetter>. It has a color that gets passed onto the letter and a top-left location.

[editline]18th August 2011[/editline]

GUIWord word = new GUIWord("hi fp", new Point(10, 10), Color.Black);
GUIWord word2 = new GUIWord("text is great", new Point(10, 70), Color.White);

GUILetter hLetter = new GUILetter('h');

word.Render(spriteBatch);
word2.Render(spriteBatch);

hLetter.Render(spriteBatch);

[Map in a box]

Now that I'm done with beat boxing with Windows, I'm thinking about making a Pandemic clone, but the world map will be a massive bitch.

[editline]19th August 2011[/editline]

Since I have no idea to make the bitch of a world map work, I'll make a 2D engine instead.

[QUOTE=Foda;31802683]Goddamnit. I guess XNA does not support SIMD? I have a buttload of particles that I need to render/update and I want a really fast way to do it without having to rewrite my entire particle system to be GPU based...[/QUOTE]

XNA is just a framework/library. You mean that the CLR JIT doesn't support SIMD (not sure if it does or not, guessing not). It might pay to write your performance sensitive code in C and P/Invoke across to it from .NET.

Oh god. Just tried Valgrind and I absolutely love it. Caught a very sneaky memory-related bug with it.
I was stress testing Voronoi diagram code and was an inch away from writing it again from scratch, and then I (re-?)discovered this (with Valgrind):
[cpp]
//const wchar_t *wFileName = pTexture->name.GetUnicode().c_str();
const char *fileName(pTexture->name.Get().c_str());
...
imageFormat = FreeImage_GetFIFFromFilename( fileName );
[/cpp]

I blame Garry (Gwen), but I guess it's my fault for overlooking that. (The commented-out line was Garry's code. With Linux kernel wchar support being flaky, I had to use chars).
(For the not-so-C++-savvy, the memory pointed to by c_str() is freed very quickly because the string it is derived from reaches the end of its life immediately after the call.)

The weird part is that I only had problems when I generated a Voronoi diagram with more input vertices.

Attempting my first actual game in XNA after lots of experimentation.

Pretty simple game where you control the red block and dodge/catch (Haven't decided yet) the blue falling blocks.

Completed the input/movement, half of the collision and the dropping of one Blue box.

When you free memory, it doesn't immediately get destroyed. You just relinquish any responsibility over it, but the data itself might stay intact for a while.
And it probably did, if you try to allocate more and more memory (or just more often) (-> more vertices), then the chance that this memory will be overwritten with something else is higher of course.

Just fucking around with some ideas for Ludum Dare this weekend, hopefully the themes I'm playing around with will get chosen.

[danharibo]

[QUOTE=s0ul0r;31822018]I don't see the letter h getting rendered :/[/QUOTE]Because it's never assigned a position or anything, I imagine it's either off-screen or he broke it.

This is a ridiculous nitpick, like -ridiculous- but why would you call that variable hLetter? I'd have probably called it letterH or letterh, just because in speach you say "The letter h" not "the h letter".

This is a mod for minecraft that basically makes you character build .schematic files that you load. It works fully in SMP without the need of any mods or anything happening on the server.

Decided to test Kari's speed against some other popular languages.

[b]Kari:[/b]

(n ->
	1 => a
	0 => b
	for 1 n (
		b => c
		a => b
		+ a c => a
	)
	a
) => fib

fib 100000

[b]Ruby:[/b]

def fib(n)
  a = 1
  b = 0
  n.times do
    c = b
    b = a
    a += c
  end
  a
end

fib 100000

[b]Python:[/b]

def fib(n):
	a = 1
	b = 0
	i = 0
	while i < n:
		c = b
		b = a
		a += c
		i += 1
	return a
	
fib(100000)

    while( i < n ) {
        var c = b;

I'm working on a game with destructible terrain, kinda like Clonk.

Basically finished this game, though I will probably add a gamemode where you collect blocks instead of dodge them.
