[Tutorial] Full Game Part 1 - Menu

[popcornx]

Recursion is a function that calls itself.

Code:

void rc(int num)
{
    if (num > 3)
    {
         return;
     } else {
       num++;
        rc(num);
    }
}

rc(1);

it will run like this:
call the function num=1;
is num > 3? no
increase by 1
call function num=2;
is num > 3? no
increase by 1
call function num=3;
is num > 3? yes
return to call #2
reutrn to call #1

oh yeah as my teacher would say "you must know recursion inorder to understand recursion"

You had a } in the wrong place.

So the lastpad check was terminated before the up/down check. Simple really  

All I've done is move one of the } from after the setting 5 part to after the down check (Only menu function shown).

Code:

void menu(){

//scePowerSetClockFrequency(333, 333, 166); //  Cpu Clock Currently Set At 333

    pspDebugScreenInit();  
    setupCallbacks();    
    powerCallbacks();  
    initGraphics();
    SceCtrlData pad, lastpad;    

    int On_Start_Menu = 1;
    extern int Select_Setting;
   
    Color Color_1 = RGB(0, 0, 0);
    Color Color_2 = RGB(0, 0, 0);
    Color Color_3 = RGB(0, 0, 0);
    Color Color_4 = RGB(0, 0, 0);
    Color Color_5 = RGB(0, 0, 0);  
   
                 
    sceCtrlReadBufferPositive(&lastpad, 1);

Inso does everything els look ok ? in the selecting thing ?
couz when i select one thing it just starts ir program

[Insert_Witty_Name]

No idea mate, try debugging it fully.

I only looked for the error you mentioned.

[faati]

any ideas that i could do to get it work ?

[Insert_Witty_Name]

It's probably something to do with this block under your X press check:

Code:

Select_Setting = 1; // Remote
Select_Setting = 2; // Mp3 player
Select_Setting = 3; // Options        
Select_Setting = 4; // Credtis        
Select_Setting = 5; // Exit

I have no idea why you're setting that variable to different things 5 times...

Also, for some reason, you have it set up so that you have to press X and Select it will run the menu function:

Code:

if(pad.Buttons & PSP_CTRL_SELECT) {
           menu();

I would seriously look at some generic C tutorials on if statements before you try and do something of this complexity.

[faati]

Inso i did this after your toturial, your toturial had 3 , i added two more but my problem is, can i make those to do different things, like when i press x in Select_Setting = 5; // Exit
it would Exit the program to eloader. but with mp3 player it would launch mp3player.
Understand me ?

[Insert_Witty_Name]

My tutorial has nothing that looks even remotely similar to:

Code:

Select_Setting = 1; // Remote
Select_Setting = 2; // Mp3 player
Select_Setting = 3; // Options        
Select_Setting = 4; // Credtis        
Select_Setting = 5; // Exit

All you are doing here is:
Setting 'Select_Setting' to 1
Setting 'Select_Setting' to 2
Setting 'Select_Setting' to 3
Setting 'Select_Setting' to 4
Setting 'Select_Setting' to 5

Take a look at this with some editing, you'll probably still need to tidy it up to work how you want it to.  This is all simple stuff, you should know more than this from the tutorials in the tutorial section of the site.

I've put some comments in too to help you along.

Basically all you're doing is catching what is selected when you click X and acting based on those results. Think about it logically, heck even draw a flow diagram on a bit of paper if it helps, it all makes sense.

Not angry mate, just think that if you don't know simple things like this then you are running before you can walk, so to speak.

There are some good generic beginner C tutorials out there that would benefit you infinitely.

Personally I've only been programming in C since 12th May, so it's not that hard to pick up.

Heh, I missed something.

You are checking the selected setting like this:

Code:

if (Select_Setting = 1) {

It needs an extra =

Code:

if (Select_Setting == 1) {

That goes for all your if blocks on the X check part.
