General / Re: Looking tips, for draving tiled background
« on: January 09, 2013, 11:46:13 pm »I was checking documentation and what it actually is and does(refearring to 'sf::VertexArray'), its just a thing i was looking for.The fps i get isThen you don't have a performance issue, so I understood you wrong.
470 - 480 on release
270 - 280 on debug
with 32x24 tiles per secondWhat i was asking for any cool ideas how not to call sf::RenderWindow.draw() function so many times.Did you look into the posted links above?
Have you checkout what 'sf::VertexArray' is?
Or did you just ignore all that?What i am trying to achieve is decrease CPU usage. Even at the cost of memory.It's simply to fix, just limit your framerate. You screen anyways can't handle 300-400 images per second and thus the cycling is just a waste of power.
This can be achieve either with window.setFramerateLimit(60) or window.setVerticalSync(true), but you shouldn't mix them!
And for performance issues, well i ... uh, depends what performance issues is defined as, and i have one am trying to improve/reduce.
I was just looking for way to decrease CPU usage. So weaker devices can handle my application.
Thank on help.

This has to do with graphics, so next time please choose the right section post it in.
Did you make your benchmarks debug or release mode? Because in the end what's important is the release mode.
A quick search in the forum would've gotten you to topics like:

That is use a sf::VertexArray.
Using SFML 2.0 with Visual studio 2010. yesterday i used CMake to build the dll files.
The fps i get is
470 - 480 on release
270 - 280 on debug
with 32x24 tiles per second

Google hates me. How do i check what version my compiler is in Visual studio 2010?

Hello.
What i have problem is, that i draw 32x32 tiles on 1024x768 screen and i get high CPU usage during this operation. The obvious cause is that i call sf::RenderWindow::draw() function too many times (768 times to be exact).
By commenting out the sf::RenderWindow::draw() calls decrease CPU usage from 60-70% down to 10%.
I currently conflict this problem by decreasing the amount of tiles i draw to screen.
Any suggestions, tips?

That's exactly what i did.
Only thing is that i cant find OpenAL32.dll i just see soft_oal.dll which they say to rename to OpenAL32.dll and use it.
Whats what i replayed last time
.
Thanks on time and good help, with good fortune.

But it said just rename soft_oal.dll to OpenAL32.dll in readme. And it seems to work as good as last one.

Downloading a random OpenAL32.dll and replacing the one from sfml fixed the error.
But now my application takes about 10-15 seconds to start...
Thanks FRex on pointing me!

I have a big application(game)
It runs as expected. But when i shut it down and code comes to being destroyed i get this error
Tracing the error i fount out it is from declaring a sf::Music object.
The problem does not occur when using Visual studio 2010
As for linking it dynamically, yes i am linking it this way.
It does not give me error that .dll couldnt be found.

Might be related to issue https://github.com/SFML/SFML/issues/30Ok il check it up, thanks. The search on forum is not working for me
This audio bug is really fishy, esecially that old openal32.dll fixes it..

Hello.
Am doing this
Press any key to continue.
I had huge program and was commenting out peace by peace until i stumbled on this.
Why is declaring sf::Music giving me error ? i also tried downloading latest snapshot build and also build my own with cmake and MinGW for codeblocks and am still getting this error, why is that?
Also what can i do to fix this?
Am coming from a post on gamedev.net if you need more info
EDIT::
I just tried reproducing error with VisualStudio2010 Express and i was unable.
The error occurs with CodeBlocks10.05 using GCC/MinGW.
Any tips how to fix it on codeblocks?
Am doing this
int main()
{
sf::Music audio;
return 0;
}
Process returned -2147418113 <0x8000FFFF> execution time : 0.100s{

}

General / Re: Minimizing application on alt+tab keypress
« on: November 28, 2012, 02:56:12 pm »Mhm... when am in "game" and i press alt + tab and select other window the "game" loses focus.I am trying to minimize the application window when user alt tabs.Note that this is not the usual behavior on Windows. Alt+Tab brings the window you select to the front and gives it focus, leaving others how they are.
I am unsure where sf::Event::LostFocus gets its info from, but its triggered when alt + tab is pressed.

After mayor fight with bugs here is how i done it.
Using "windows.h" and sfml events
Here is how i done it in a nutshell if anyone needs it.
when sf::Event::LostFocus is triggered i do following
if isFullScreen == true{save all data of window, create a new window that is not fullscreen "NOTE most update handle from window.h when you recreate a new window", limit frames per second to 1 to save process, and using windwos.h function ShowWindow(myWindow, SW_MINIMIZE), make infinite loop where games only handles 1 event "sf::Event::GainedFocus" }
else { limit frames per second to 1, make infinite loop where games only handles 1 event "sf::Event::GainedFocus}
when in this infinite loop the sf::Event::GainedFocus is triggered
if isFullScreen == true { recreate old window using data that was stored "NOTE most update handle from window.h when you recreate a new window" and use windwos.h function ShowWindow(myWindow, SW_RESTORE) to restore window to its previous location and info, turn off limit on FPS, break the infinite loop and go into game}
else{turn off limit on FPS, go intro normal game related stuff / break the infinite loop};

General / Minimizing application on alt+tab keypress
« on: November 28, 2012, 01:00:34 pm »
Hello.
I am trying to minimize the application window when user alt tabs.
I tried using void sf::Window::setVisible(bool visible)
but it hides drawing window but also hides from taskbar and user cant access it ever again.
also when in console it gives this "Failed to share openGL context"
Does sfml support this, or i most go OS specific function?
Also how to invoke the "Minimize" on a window using windows7?
EDIT::
The problem is fixed at 5th replay to this post(Scroll down), if your having problems go check it out.

Id be damn, it works...
Thanks for the info, will spread it.
Passing int as parameters to setPosition(); removes blurr
Also moving it around does not help.
