What are you working on? December 2011 Edition

[QUOTE=Night-Eagle;33694370]Change "if x and y" to "if !x or !y", sell. You would require a 1,000 page document to adequately define "unmodified", and then no one would be arsed to use your software from fear of litigation. Also, a lawyer would probably rip that license up as it is written. You give rights "without restriction", and then you apply restrictions to those rights?

There is already a license for this intent, and it's called the GPL. If someone wants to make a full-blown game based on your work that you're afraid of getting stolen, they can contact you and obtain special permission under a separate license agreement. The GPL would be perfect in this scenario.

Not trying to be mean, but the law is very unforgiving from what I can tell. I'd hate for someone reading this thread to have a Lugaru pulled on them.

If art assets can cover your ass, however, then go for a full-blown MIT license.[/QUOTE]

Taking this into consideration and writing a much better version.

Well this fucking IDv3 library has never heard of null-termination, and doesn't want to provide a length of the string.

What's the best way to take keyboard input and write it to a string in XNA? Just make a separate instance for each possible key?

[QUOTE=ROBO_DONUT;33694957]It matters because I've [i]never [/i]gotten a mono 'port' to actually [i]work[/i].[/QUOTE]

I agree with ROBO_DONUT on this one, it's a horrid experience compared to native.

Example (Vapor in mono):
[img]http://j.mp/sg70sV[/img]
right-click menu is broken, doesn't follow system theme, and doesn't go away when click off of it. mousewheel doesn't scroll, my status is hidden behind "Online" (rendered as a black box), and the window doesn't shrink properly to taskbar. And apparently it's render order is messed up when I attempt to take a screenshot of it.

When it works just fine in windows.

[Yogurt]

Also I'm gonna need some time to fix this up--it ties into a lot of other stuff in my engine.

You could compare the GetPressedKeys() from the current frame with the one from the last frame and add any characters that are in the current one but not last frames'

[QUOTE=NovembrDobby;33695619]You could compare the GetPressedKeys() from the current frame with the one from the last frame and add any characters that are in the current one but not last frames'[/QUOTE]

I just have a KeyInputManager that I call BindKey() to. I specify a Keys enum, a lambda that should be called when the key is pressed, and booleans that determine whether it's on press or release, whether it's only ON press or constantly DURING press, etc. I like it. A lot.

[QUOTE=thisBrad;33694525]Anyone know a Character encoding library? GNU iconv doesn't work. I need to convert UTF-16 to ASCII.[/QUOTE]

UTF-16 to ASCII? Well, that's kind of easy, but you shouldn't be doing it. Why? Because Unicode isn't ASCII. It contains tons of languages and gylphs that just aren't in ASCII.

But if you're COMPLETELY AND ABSOLUTE SURE that your stuff only contains letters that are from the ASCII character table, Garry's method MAY work.

You should keep your program Unicode compatible. Personally I store all my strings in UTF-8 which is ASCII compatible, then convert them for API purposes.

But as for a library, iconv does work. If you want me to dig up some code I can, but if you're willing to spend a few more megabytes on library storage, I can't recommend Boost.Locale enough. It deals completely with Unicode, and has code page conversions and code page to Unicode and back functions.

[QUOTE=reedbo;33695442]Can anyone else working with SFML2 post the source of an example game working with a state engine? I can't really seem to grasp the concept of a using a state engine for a game and google really isn't helping me.[/QUOTE]

Shameless plug, but I did probably what you want with SFML2 and C++ for the Bacon Game Jam. [URL="https://github.com/Jookia/dplane"]Here's the sources.[/URL]

You could always be open source like Windows is. You know, as long as you license it so you people can't legally modify or redistribute it. Microsoft loves open source (they obviously avoid the term 'free software')

[Mimi_C]

I recently decided to move away from C# and XNA and start using C++ with SFML and and as a first project I decided to rewrite a simple particle system I wrote for XNA.
Probably not the best idea.
For the most part, the transition from C# to C++ hasn't been too hard. I have ran into a problem though and need some help.

What I have is a Particle class and a Particle_System class. The Particle_System class creates a list of particles and adds particles to it with a generate function.
What I want to do is iterate through the list to update and remove any particles that are dead.

I found this when searching and tried out the first answer.
[url]http://stackoverflow.com/questions/596162/can-you-remove-elements-from-a-stdlist-while-iterating-through-it[/url]

This is what I got.

void Particle_System::Update()
{
	std::list<Particle*>::iterator it = parts.begin();
	while(it != parts.end())
	{
		*it->Update();

		if (*it->life_left <= 0)
		{
			parts.erase(it);
		}
		it++;
	}
}

But Visual C++ is giving me the following errors.
error C2678: binary '!=' : no operator found which takes a left-hand operand of type 'std::_List_iterator<_Mylist>' (or there is no acceptable conversion)
error C2440: 'initializing' : cannot convert from 'std::_List_iterator<_Mylist>' to 'std::_List_iterator<_Mylist>'

Thanks.

There's a joke in this about game developers making tutorials and not games, but I just can't wrap good words around it.

States are pretty awkward if you have any lengthy experience with a large engine prior to working on your own game though.

Don't use states.

 /*
    Somewhere deep down inside, I feel bad for having this if statement.
    Maybe it degrades the game's performance by 200% due to operator
    overloading? Maybe I could've put a note 'DO NOT USE WITHOUT A STATE SET',
    and allowed the program to SEGFAULT. But then my program wouldn't work 100%
    of the time. I'd wake up in the night screaming, imaging endless bug
    reports of tinkerers forgetting to set the state. Windows sending error
    reports of my program to Microsoft, for them to know the crime I'd of
    committed.
    No.
    Not on my watch.
    So with all my might, I cast an if statement forged from uninitialized
    memory itself, to protect my program from a case that will probably never
    happen.
