Graphics / Cannot Access Private Member in class "sf::NonCopyable&

« on: June 23, 2011, 03:18:58 am »

You're missing the break statements in your switch block. It should look like this:

Code: [Select]

  case left:
      object->Move(-5, 0);
      break;
   case right:
      object->Move(5, 0);
      break;
   case up:
      object->Move(0, -5);
      break;
   case down:
      object->Move(0, 5);
      break;

Otherwise, if you press left, it will also run the code for right, up, and down.

Graphics / Problem with drawing outside of RenderWindow init function.

« on: June 11, 2011, 12:15:52 am »

I think the issue is that you declare "sf::Mouse::Button b", but you never initialize it before you use it, so it contains a garbage value that causes IsMouseButtonDown to crash.

You should instead do something like this:

Code: [Select]

sf::Mouse::Button b(sf::Mouse::Left);
or this:

Code: [Select]

...App.GetInput().IsMouseButtonDown(sf::Mouse::Left)

The reason it doesn't crash until you move your mouse over the sprite is because of "short-circuit evaluation".

Graphics / SFML 2.0 Creating OpenGL 3.2 Context

« on: June 05, 2011, 09:19:03 pm »

You are only calling the ContextSettings constructor, you aren't passing it to the RenderWindow constructor.

Here is what I use in my project, except using Window instead of RenderWindow:

Code: [Select]

sf::Window window(sf::VideoMode(800, 600, 32), "Game", sf::Style::Close, sf::ContextSettings(24, 8, 16, 3, 3));

Great, thank you.

No problem  

I added some additional information to my first post which may help.

Also, thanks for making such an awesome library. It is much nicer than SDL and others that I have used.

Network / UDP packet occasionally not received correctly?

« on: October 16, 2010, 08:49:18 am »

[SFML 2.0, rev 1582]

I set up two UDP sockets on localhost, and have one socket constantly send a packet containing '42' to the other (nonblocking) socket. Occasionally '0' will be received instead of '42'.

Am I doing something wrong?

Thank you.

Here is my code:

Code: [Select]


const int CLIENT_PORT = 2364;
const int SERVER_PORT = 2365;
sf::UdpSocket socketClient, socketServer;
socketClient.Bind(CLIENT_PORT);
socketClient.SetBlocking(false);
socketServer.Bind(SERVER_PORT);
sf::IpAddress theAddress("127.0.0.1");

while (true)
{
{
sf::Packet packet;
packet << 42;
socketServer.Send(packet, theAddress, CLIENT_PORT);
}

{
sf::Packet packet;
sf::IpAddress address;
unsigned short port;
if (socketClient.Receive(packet, address, port) == sf::UdpSocket::Done)
{
if (address == theAddress && port == SERVER_PORT)
{
int temp;
packet >> temp;
if (temp == 0)
{
printf("Value is 0\n");
}
}
}
}
}


[EDIT]
Some additional information: if I grab the size of the packet before trying to set temp, and then print it out when temp is not correct, these are some of the values I get:
131022,393050,65515,2227246,196525,982609,262032,7533309
Note that they all seem to roughly be multiples of the same number, 65515.
