Window / sf::Input.GetMouseX() and Y()
« on: December 18, 2010, 09:50:57 am »
Any ideas? I don't want to be limited to 200FPS. Also, if I set the framerate limit, the problem persists.

General discussions / How to make an sprite go to correct direction
« on: December 18, 2010, 01:18:01 am »
The easiest thing to do is to store the player's current direction somewhere, so you can then apply that to the bullet.

Window / [SFML2] Input on another thread
« on: December 18, 2010, 12:50:32 am »
It probably isn't worth having the input thread on a seperate thread. If one thread is held up (e.g. rendering), the input will be problematic, and gameplay could be adversely affected.

Window / sf::Input.GetMouseX() and Y()
« on: December 17, 2010, 10:50:42 am »Quote from: "Laurent"
Try moving your event loop at the beginning of your main loop.
Hasn't worked

Then, what does "The view hardly moves with the same mouse movements" mean exactly? What framerate do you have?
In Linux, if I move the mouse say 5cm, the view on screen moves as expected in the window.
However, in Windows, for the same 5cm mouse movement, the view moves a much smaller amount, and in jumps. The framerate stays relatively constant. (~300-400 FPS)

Complete code? Here we go...

SFML projects / Can Someone Test My Game?
« on: December 16, 2010, 08:28:43 am »
Yeah, I got the following error in Windows 7 32-bit when I run it. The same thing happeans with each .dll
"C:\Users\***\Desktop\Pikin\OPENGL32.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support."
Did you only compile on a 64-bit machine? That's the only obvious problem I can think of.

Window / sf::Input.GetMouseX() and Y()
« on: December 16, 2010, 08:06:56 am »
I call it just after creating my sf::RenderWindow() object (outside the game loop). I tried moving it to the main loop, but it didn't help out.

Window / sf::Input.GetMouseX() and Y()
« on: December 15, 2010, 02:44:50 am »
Fixed it somewhat. Added sf::Sleep(0.005) to the mail game loop, but this does expectedly lower the framerate. Is there a better way to give the inputs a chance to register, but keep a higher framerate?

Window / Is window in focus or minimized?
« on: December 15, 2010, 02:25:58 am »
There are the events LostFocus and GainedFocus, but these don't really work with minimising. Unfortunately you'll have to wait until SFML 2.0 for Activated and Deactivated.

Window / sf::Input.GetMouseX() and Y()
« on: December 15, 2010, 12:33:05 am »
I have written some movement code for SFML 1.6 as follows:
I then use OpenGL to rotate and translate blah, but that's not important.
Now, in Arch Linux x86_64 (with X11 and XFCE), this works fine. The view rotates fine.
In Windows (Windows 7 32-bit), it's a different story. The view hardly moves with the same mouse movements. It's so annoying! However, the keyboard movement is exactly the same.
What's going on?
Code: [Select]
while (App.IsOpened())
{
moving = false;
// adjust x- y- and z- step amounts based on current direction/view rotation
xStep = playerSpeed * sin((PI * zRotation) / 180);
yStep = playerSpeed * cos((PI * zRotation) / 180);
zStep = -playerSpeed * sin((PI * rotation) / 180);
cout << "zRot: " << zRotation << " rot: " << rotation << endl;
// process real-time input
if (Input.IsKeyDown(sf::Key::W)) // W = forwards
{
moving = true;
playerX -= (xStep * cos((PI * rotation) / 180));
playerY -= (yStep * cos((PI * rotation) / 180));
playerZ -= zStep;
}
if (Input.IsKeyDown(sf::Key::S)) // S = backwards
{
moving = true;
playerX += (xStep * cos((PI * rotation) / 180));
playerY += (yStep * cos((PI * rotation) / 180));
playerZ += zStep;
}
if (Input.IsKeyDown(sf::Key::A)) //A = strafe left
{
if ((moving = true))
{
xStep *= 0.707106;
yStep *= 0.707106;

}
// Rotate view based on mouse movement
mouseDeltaX = Input.GetMouseX() - centreX;
mouseDeltaY = Input.GetMouseY() - centreY;
