i use %d for an integer anyways

i'm having a prob with my ad-hoc i almost have it working i just ran into one tiny prob:

Code:

---

matchingid  = sceNetAdhocMatchingCreate( 3,0xa,0x22b,0x800,0x2dc6c0,0x5b8d80,3,0x7a120,callback);

---

the last parameter is to tell the next function where to put the proper information (which is into a function and yes this is possible as the example i'm working off works perfectly with it and it is also what the sdk documentation says 2 do)

Code:

---

int nams=sceNetAdhocMatchingStart(matchingid,0x10,0x2000,0x10,0x2000,6,"adhoc\0");

---

now then that should be sending the data directly into that function and the function should be called....thats where the problem is

the int returns as successful however it doesn't call the function which is the problem=-(

any1?

"A stack-based computer system is one that stores temporary information primarily in stacks,"
when is information temporary ? I mean just int a = 5; isnt temporary I guess because you still could need it , but do they mean like this

int h (void)
{
int vijf = 5;
int twee = 2;
int product = vijf * twee;
return product;
}


so "vijf , twee and product" are temporary ?

Code:

---

int h (void)
{
int vijf = 5; // Gets pushed onto the stack
int twee = 2; // Gets pushed onto the stack
int product = vijf * twee; // Gets pushed onto the stack
return product;
} // product popped off the stack
// twee popped off the stack
// vijf popped off the stack

" last in first out " , thnx

But when you do this
PSP_MAIN_THREAD_STACK_SIZ E_KB(32);

the stack is only 32Kb big , how doest it work with for example
char buffer[128*1024]; or void *buffer = malloc(100*1024);
Thats bigger then the stack , but I guess that file types arent temporary ?

malloc allocates from the heap, not the stack.

and why will people use a smaller stack then the normal , unless they need ALL the avaible memory

i'm ganna take it no one knows what is up with my problem

edit: i finally fixed the program and ad-hoc is working awsome=-)

just check i got how to use sprite sheets correct
blitAlphaImageToScreen(0 ,0 ,32 , 32, example, 64, 64);
The first 2 numbers(both 0's in this case) is the top corner of the image
The next to numbers(both 32's in this case) is the hight and width of the image.
Example is the name you want to assign to that part of the image.
The next two numbers are where the image will be displayed on the screen.

Is that correct?

Yep.

I have heard there are ways to compile C code without cygwin. If this is true which is the best method?

mmm, before i had something like PSPDev and i didnt have cygwin installed...

---

Yes. PSPDev, which is out of date and DevKitPro which is a precompiled toolchain with minsys instead of cygwin as the bash shell.

There is no best method.

doesnt matter.

^^ why not use dsx. its easier:tup:

because font size is huge ...

How do you acctually make an EBOOT after you finish your script?

you need to create a makefile

Where and how do you find the makefile?

Can YOU please make me a small guide over PM?
-= Double Post =-
I just made the source files, and now I am ready to make it an EBOOT.PBP.

I made a makefile in notebook with this inside:

Code:

---

TARGET = RECOVERY NORWIGIAN
OBJS = main.o

CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Norsk RECOVERY meny

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

---

I open CYGWIN and typed

Code:

---

cd project/recovery

---

and get this message back:

Code:

---

make: psp-config: Command not found. Makefile:12 /lib/build.mak: No such file or directory
make: *** No rule to make target lib/build.mak. Stop

---

Can someone help me?

Do you have the toolchain installed and configured?

EDIT: You could try this, it worked for me. Replace the line:

Code:

---

$(PSPSDK)/lib/build.mak

---

With:

Code:

---

C:/cygwin/usr/local/pspdev/psp/sdk/lib/build.mak

---

Assuming that 'C' is you drive letter and that you installed cygwin in the root of your hard drive.

No, I dont have toolchain installed. JaSo PsP, can you please send me a PM with an guide, thanks. :)

I dont understand this so well:

does anyone know, why this doesnt blit string? its invisible...

blit_string46 works, but that also sets BGcolor O_o

Tostoo: Follow this guide. It will tell you how to set up the toolchain within cygwin. Then follow the lessons after that so you know how to compile PSP applications correctly.

yeah i did.. and example prints text but my code doesnt o_O

Use pgeFont...

ok, i will install freetype and test it

edit ... mm hello world prx is 754 KB big o_O...

i am unable to open a usb connection from within my program if i run it on the 352 kernel (it works perfectly on the 150 so i'm guessing sony have added protections or something)

anyway i've tracked down the command thats causing the failure in the 352 kernel, here it is

sceUsbstorBootSetCapacity (0x800000);

can anybody help?

When I compile an EBOOT in CSP where is it stored? Is it stored with complete folders or do one have to create them self? Is there a manual online somewhere?

They EBOOT.PBP is created in the same directory as the project and source files.

in uno wouldn't there be 112 cards...i've been looking over the card numbers just to make sure i get everything correct for my game and i'm running into a prob:

from site: http://www.wonkavator.com/uno/unorules.html

19 Blue Cards - 0 to 9
19 Green Cards - 0 to 9
19 Red Cards - 0 to 9
19 Yellow Cards - 0 to 9
8 Draw Two cards - 2 each in Blue, Green, Red and Yellow
8 Reverse Cards - 2 each in Blue, Green, Red and Yellow
8 Skip Cards - 2 each in Blue, Green, Red and Yellow
4 Wild Cards
4 Wild Draw 4 cards

now then here the thing if their are suppose to be 0-9 twice wouldn't that make 20 cards not 19? can some1 plz explain as to why their is an odd number i want to be sure i get my deck correct before i go on(i know the rest of the rules but this is the part that i'm getting confused over)

Correct.

One card value isn't in twice.

Your code should be generic enough to handle this minor change either way with VERY little source changes. If you can't, rethink your code design.

which card so i can make sure it doesn't place it in the deck twice

Buy a pack of Uno cards. I know nothing about Uno and the answers to your questions can be found by applying some logic.

i had a pack and would have looked them over if i hadn't loss them ok well thanks

Also, Uno has 108 cards, not 112.

i know i was just saying wouldn't it have 112 cards if it were 20 not 19 cards

This problem is not a showstopper. You can still develop the full game without any problems whether you go with 19 or 20 cards. When you do find out which value only has one card, then the code change should be VERY minor (barely 5 minutes work). If it isn't then your code design is poor.
