BRUNNI, ton anglais et marvelous, puis arret de dir votre anglais et pas bon, parceque mon francais is WORSE!!! ;)
Your lib kicks ass. Love it. I have a couple of questions.
1) what does oslCreateSwizzledImage do? is this meant for loading images into VRAM ? there seems to be no documentation on this
2) in your maps/sound sourcecode with the 8 layers (very cool example) how do you create the maps.h file? is there a tool to convert png to c code? and does that support ALPHA? OSL_PF_8888
3) OSL_MAP ; oslDrawMapSimple ; oslCreateMap ; where can i get information on this, i don't understand how you are infinately scrolling in that maps/sound example.
| Code: |
nuages = oslCreateMap(
nuagestileset,
nuages_map,
8,8, //<---???
64,34,
OSL_MF_U16); //<--???

Swizzled textures have reordered pixel data to optimize read access. I general you should swizzle all your textures because the performance difference is very significant. |

ok so i load my image
tmpImg = oslLoadImageFile(filename, OSL_IN_RAM, OSL_PF_8888);
then i swizzle it, and use the swizzle image
newImg = oslCreateSwizzledImage(temp, OSL_IN_VRAM);
makes sense, thanx __count.
Anyone know the answer to #2 and #3 in my previous post? |

Have you read the documentation? It's very good.
I've been wondering how he did the maps.h code too. Probably by hand, but I'm not sure. I'll figure it out someday. There are tools to convert png to c(gimp can save images as c or h), but that's not the case here. If it were, there would be no reson to include the tilesets. Another reason why I think it was written by hand.
As for your 3rd question, read through the documentation and source code til you understand how the whole thing works. |

thanx for the tip, heres a link for ppl who wanna convert there GRFX to C header style code (i have yet to try)
http://www.megagames.com/gba/files/gfx2gba.zip
(btw brunni you should include it in your tools as part of the OSLIB)
------------------------------------------------------------------------------------
nope.. it works but itz not what is used in his map.h file...
i spent several hours trying to find several tools, and none come close to the same output like the map.h
so brunni what do you use? is it your own converter? |

Everything works perfectly but, when I add sound, the screen starts to flicker, I'm not sure why.

Replace your makefile with this and tell me if it works.
| Code: | TARGET = theGame
OBJS = main.o
CFLAGS = -G0 -Wall -O2
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
STDLIBS= -losl -lpng -lz \
-lpspsdk -lpspctrl -lpspumd -lpsprtc -lpsppower -lpspgu -lpspaudiolib -lpspaudio -lm
LIBS=$(STDLIBS)$(YOURLIBS)
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = The Game
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

| you should probably update your libpng, your sdk, and maybe even the oslib. |

yeah, Cygwin installed perfectly on the computer I'm using, and my laptop, but for some reason it couldn't install on my other computer. Weird huh? Well, whatever works for you. Goodluck. |

Oh, didn't see that. I'll try it and see if it works :)

Sorry I didn't come for a while :-'
1) For USB you must be in kernel mode (you can create a user thread after you loaded the drivers, and use OSLib from either the user or kernel thread, but I recommend running it from the user one - as the rest of your code - for safety reasons).
* There is no more built-in support for USB in OSLib as it requires kernel mode (even if USB is not used), and I don't want to oblige using kernel mode.
2) yourfont = oslLoadFont("yourfont.oft"), then oslSetFont(yourfont) and oslPrintf, oslDrawString and so on ;)

Hi,
I'm using OSlib to add sound to my engine, but I've run into a wierd problem.
If I play the sound once just before my main loop, it works fine.
But if I do this,
| Code: |
if( joy->_triangle==1 )
{
oslStopSound(snd);
oslPlaySound(snd, 1);
}
|
It's as if the sound is being played a thoushand times at quater of a second intervals.
Almost as if the oslstopsound was not working and it was buffering up a shedload of play calls. And it goes without saying what is audible is nothing like the original sound.
But the first method, play once before main loop sounds identical as to it does on the pc.
I think what you might need (Depending on what's causing this) is a channel system. Where by each play sound allocates a channel and returns it, and you can then stop the channel before playing the sound again.
Also will you be adding soundpitch to alter the pitch of a playing sound?
Nice lib btw. |

ok I changed it to this,
| Code: |
if( joy->_triangle==1 )
{
if(playsnd==0)
{
playsnd = 1;
oslPlaySound(snd, 1);
}
else
{
}
}
else
{
playsnd = 0;
}
|
and the sound now plays fine in the main loop, but only once. it never rings twice much to dismay of glenn close. |

You should use the oslib's built in control functions.
| Code: |
if( osl_keys->pressed.triangle )
{
oslPlaySound(snd, 1);
}
|
That's a good technique for sound effects, and it should work if your playing music. Tell me how it goes. |

How would I have an image scroll itself? I tried increasing offsetX0 and offsetX1, which works, but has a seam when it repeats. Any ideas?
Also, is there a complete example of drawing to an image? I tried the code snippet from the docs but that only worked in the PC test harness, not on the PSP. |

Is there a new version of oslib out? oslDrawString doesn't seem to exist in the documentation or in oslib.h...
Fixed my compiler problems btw, everything's working perfectly under linux... stupid windows.... |

You can also convert an existing Windows font (run font2osl.exe without parameter for more info). |
I tried running font2osl.exe but it only popsup for 1/10th of a second and then colses by it self..
it says:
tried copying a font over to the directory but that didn't help.. Does anyone know whta to do? |
