Are you sure you're using the right version of SFML? SFML 2.0 has "isOpen" and "pollEvent", but SFML 1.6 has "isOpened" and no pollEvent.

Tried isOpened and it also didn't recognize that as a member.
I'm on Ubuntu, and I used the official repositories: sudo apt-get install libsfml-dev.

Older SFML versions don't use camel-back notation. It should be IsOpened, not isOpened.

The ubuntu packages are the stable version (1.6). You need to compile the 2.0 version yourself. Not hard, the cmake-gui package can help you if you're unfamiliar with cmake

I'm trying to minimize the communication between my server and client for example having the server tell the client that a character shoots in one direction, and the client will know what weapon that character is using, what kind of projectile to spawn, and where other players are for the projectile to collide with. Is this is a bad way of doing it because it can potentially be unreliable, or is better because it will reduce lag?

As long as you verify everything on your server, it should be fine.
For example, for a multiplayer game I am (slowly) working on in my spare time, I intend to have the AI be predicted on the client. Whenever an AI updates his movements or behaviors, it will send an update to the relevant clients - in the case of movement, it will simply use vectors, or directions with speed.
So instead of constantly updating an AI's position while traveling in a straight line, I simply send to the client that an AI is going in a straight line with a certain speed, and let the client predict it.
Cuts down on networking, but minimalizes chances of cheating and such because things are still verified by the server. While this means there may be client issues (such as slightly teleporting AI), I personally think it's the best approach.
So you can do your idea there, but just be sure you keep track of everything so you can verify it on the server. While you should never trust your clients to make decisions, there's no reason to hold their hand through everything - just be sure you can verify any important decisions like shooting or movement.

Mess around with UTGame and see how it works before trying to inherit from the UDK or non-UDK bases. There's a few tutorials around (see [url=http://udn.epicgames.com/Three/DevelopmentKitGems.html]UDKGems[/url]) but you're best off learning from the documentation at UDN and code that ships with the UDK (UnCodeX is a brilliant program).
Don't edit anything in any of the Development/Src/ folders that already exist however, always derive.

ar[X + Y*Width];

It's the x value...
plus the y value time the width of a row...
plus z value times the number of elements in an xy slice (width * height).
The width factors out, so you get this:
[code]array[x + (y + z * height) * width][/code]
You'll notice that this bit
[code]y + z * height[/code]
looks a lot like what you had for 2D:
[code]X + Y*Width[/code]
...which is because it [B]is[/B] a lot like that.
Try something like this

string::getline has a very nice delimiter parameter that does what you want

Oh, I forgot, s in the stringstream would be your string
either that or you could just declare the stringstream and do stringstream.str

IE 4 digits per number
and the code I use now is:
[cpp]
bool result = bitmap.LoadFromFile(imageFile.c_str());
std::ifstream myfile;
try
{
myfile.open(fontFile.c_str());
if (myfile.is_open())
{
int arrVal = 0;
while ( myfile.good() )
{
std::string line;
std::getline (myfile,line);
int jump = 0;
for( int n = 0; n < 4; n++)
{
std::string str = "";
int numb = 0;
int pos = n*5;
str += line[pos];
str += line[pos+1];
str += line[pos+2];
str += line[pos+3];
std::istringstream ( str ) >> numb;
Positions[arrVal][0+n] = numb;
}
arrVal++;
}
myfile.close();
}
}
catch(int e)
{
myfile.close();
result = false;
}
for(int i = 0; i < 256; i++)
{
std::cout << Positions[i][0] << ":" << Positions[i][1] << ":" << Positions[i][2] << ":"<< Positions[i][3] << std::endl;
}
std::cout << "Blah" << std::endl;
[/cpp]
which outputs correctly but creates a segfault on returning, do i have to flush a buffer or something that I have missed out?
[editline]18th May 2012[/editline]
the call stack is:
#0 0x284c6c ??() (/usr/lib/i386-linux-gnu/libstdc++.so.6:??)

#3 0x8052b3a main() (/home/richy/codeblocks/FPS/src/Main.cpp:7)
segfaults with arrays is usually caused by trying to access an index that doesn't exist in the array
don't know your specific cause since your code looks good to me but it's worth looking into

[cpp]
glBindBuffer(GL_ARRAY_BUFFER, vertexbuffer);
glBufferData(GL_ARRAY_BUFFER, VertexList.size() * sizeof(GLfloat), &VertexList[0], GL_STATIC_DRAW);
glBindBuffer(GL_ARRAY_BUFFER, uvbuffer);
glBufferData(GL_ARRAY_BUFFER, UVList.size() * sizeof(GLfloat), &UVList[0], GL_STATIC_DRAW);
[/cpp]
Would there be any benefit in using [B]glbuffersubdata[/B] when im just going to completelly re-write the data?[/QUOTE]
I do it the same way just because if the number of characters change, the size of the buffer changes and glBufferSubData does nothing to reconcile that difference. I suppose you could check to see if the sizes are the same (by storing it locally, not by calling glBufferParameter) and call glBufferSubData if they are.
The performance difference would be minimal and the code would become less readable. Keep replacing the data until it becomes a performance issue.
Does anybody have links to good tutorials about how to set up Qt4 with Windows?
I tried following the official one on qt.nokia.com but I am really moronic about setting up compilers and libraries on Windows.
I really just want to get this set up with either Netbeans or just a simple text editor and it's frustrating the hell out of me.
Symptoms:
* Running [I]qmake [/I]on my projects produces a shit-ton of errors but works (something about the EPOC directory being undefined)
* Subsequently running [I]make [/I]on the project doesn't work at all
* Netbeans generally just being an asshole and not working with code highlighting, the Qt libraries or anything else remotely helpful even though I've defined the tool set properly
* All of the tutorials address the directory called C:\Qt... etc; my Qt4 installation is under C:\QtSDK\atonoffuckingsubdirectories and I'm concerned I didn't set it up right
At this point I'm totally fine with just using Notepad++ to edit the source files and designing the UI in QtCreator. That would be ideal, actually, seeing as how Netbeans refuses to work at all.
Any suggestions?

Note: I really don't care if the tutorial wants me to use cygwin or minGW. Either is fine. Keeping an open mind here. I just want to be able to learn the code instead of fucking around with the libraries and intsallation.
