I`m using glfw to handle pads (DarksdK only supports one pad at once) so I`ve done a little test to see if they work together. While they apear to work fine I`ve noticed that the programs memory usage just increases over time. Is this normal behaver? I haven`t left it long for fear of crashing my pc but it got up to 20 megs and didn`t show any sine of stopping.

P.S LoopSDK just returns a 0 when the x button is clicked right? Just worrying if my program actually gets to glfwTerminate();.

At the moment we're not sure about that...

And it gets worse if you have multiple joysticks, of which at least 2 are the same type...

As for your main problem - I have't used that for a while, so I dont know. There didn't seem to be a problem when someone did the plug-in using that.

Unfortunately I cant test it...

Darn. Maybe I should email Mike?

Well I`ve found out it has nothing to do with glfw. I run it on it`s own and it stays at some 8megs. I run another DGSDK program and the same problem happens though it increases at a slower rate. Probably due to the fact that it runs at a slower frame rate. I`ve also tried it with Leo Christopherson`s snake game and the same thing happens. Even with the precompiled version. So I`m guesing this is just how directx works right? Or could this be a bug with DGSDK?

Thr GL joystick system uses OpenGL (hence the name) - or possibly Win32's way of reading joysticks. Either way, I dont think it uses DirectX.

I would be more inclinded to say its a problem with the GL library myself, although it would be the two systems interfering with each other...

It must be a fault my end as this memory thing happens with all DGSDK games. I might trying seeing how much memory the programs go to later. Though I don`t like crashing my pc on purpose it might be that it just hadn`t finished allocating memory. Does it happen on your pc?

Yes, memory usage seems to be steadily increasing.

It seems to be either dbPrint or dbStr causing the memory problem - my tests show it appears to be dbStr.

Try this :

Same problem. I declare dbStr guilty as charged. So do I send that email to Mike?

ah ok. By the way. Do you know a way to print a float to screen without dbStr?

char tmp[256]; //or whatever
float myFloat = 0;

sprintf(tmp, "%f", myFloat);
dbText(10, 10, tmp);

sprintf requires you to #include "stdio.h"

Cool. Thank you.
mmm I need to learn how to make longer sentances.

Edit:
Bouncy Brick: I think I`ll email Mike anyway. I need to know how LoopSDK works before I crash my pc.....

Hole? You mean 'leak'.

LoopSDK will return false when the window is closed - whether from the X being hit, ALT-F4, or from otherwise receiving the WM_CLOSE message.

Well my logic was that in order to have a leak I would have to have a hole. Like when a buket leaks water it has a tiny hole in it. So I wanted to know if I had a hole and if so where it was. I wondered when someone was going to ask that question.

Ah cool. Then it works how I want. Thank you.

Ah it won`t work. Aswell as returning false it calls PostQuitMessage(0) which exits imediatly. In order to have it just exit the function you have to use:

Thanks to Mike for this information.

mmm. No. I didn`t ask. I thought it would be rude if we both sent him emails asking about it. He did give the code to LoopSDK though:

Did you get info about dbStr? Should we place bets on patch 1.2? Maybe there`ll be a patch 1.12.

Haven't heard from Mike about - probably busy (or storing it for later on)...

There wont be a patch for a while yet due to the physics thing...

Ah, that explains a few things ... I didn't know that LoopSDK was quite that light - I thought that it included a standard windows message loop to. I wonder where the windows messages get handled?

The standard windows message loop is contained in the core library. When a quit message is received the global g_iDarkGameSDKQuit is set to 1 and this is where the LoopSDK function comes in. Its purpose is simply to check when a quit message has been sent and then to break out.

I will have a look at the dbStr function and see what can be going wrong.
