It's a file browser ;)

It doesn't look like it uses any libraries that are not included as standard so that should be fine, just add the file_browser.o to the OBJS line.

[SuperBatXS]

hello, I would like to use Jono's web browser example for my project...
http://www.psp-programming.com/forum...ic,1333.0.html
I was just wondering, can any body make a working makefile for that? Thanks for your time...

Lol, it's a file browser. Not much of a makefile for it.

Edit: Lol, you beat me by like only a couple of seconds Insert_Witty_Name

[BlackShark]

lol ok, thanks

Blit. Flip. WaitVblankStart X number of times. 60 times for a second.

"WaitVblankStart(60); ", how come this doesn't work? Am i not using the right code? It doesn't compile. I blit the image, flipped it, put this line, and clearscreen(0); What is the exact code you are telling me?

use a counter, its not that different from a timer (in your case, atleast):

int main()

int showTime = 0;

// LOAD IMAGES AND CALLBACKS AND THE OTHER STUFF //

	for (;;) {
	
		if (showTime < 60) { // EVERY 60 IS A SECOND //
			// DISPLAY PICTURE //
			showTime++;
		}
	
		flipSceen();
		sceDisplayWaitVblankStart();
	}

return 0;

}

return 0;

}

So how do you do like a if showTime > 240 and if showTime < 480?

[yaustar]

Read about if statements: http://www.cprogramming.com/tutorial/lesson2.html

[BlackShark]

So how do you do like a if showTime > 240 and if showTime < 480?

you'd do just that...

if ((showTime > 240) && (showTime < 480)) {

[Grimfate126]

you'd do just that...

if ((showTime > 240) && (showTime < 480)) {

you cant do that, you're thinking about lua. that will generate errors. here, this works:

if ((showTime > 240 && showTime < 480)) {

[Moca]

you cant do that, you're thinking about lua. that will generate errors. here, this works:

if ((showTime > 240 && showTime < 480)) {

It wont generate errors -_-

if ((showTime > 240) && (showTime < 480)) is absolutely fine.

[BlackShark]

I didn't know you can do that in lua :P

cool, well grim answered your question.

[Xylem]

Lol, i found that out quite a while ago. This works fine for me:
if (showTime > 240 && showTime < 480)

[Grimfate126]

I didn't know you can do that in lua :P

cool, well grim answered your question.

with lua, you can use ( and ) just about anywhere ;)

[youresam]

you cant do that, you're thinking about lua. that will generate errors. here, this works:

if ((showTime > 240 && showTime < 480)) {

1. That wont generate errors
2. This is the C/C++ Help Thread, he isnt thinking in lua.

fixed , was a prob with my pc

this is my main:

How about a "Get Started on 3d/PSP GU for Dummies" kind of thread?
That has all the tutorials[freshly cooked, not copy pasted] and Defines all 3d terms like culling fulling ,etc? Just so that it acts like a very useful central repository...

3d HB is also becoming near-rare.
I read up on psp-programming but they seem too intricate to understand. and also complex.

That menu won't work. I suggest you look a few pages back for the menu code I posted. It uses the graphics library though.

Go to Nehe ( http://nehe.gamedev.net/ ). Learn C, learn OpenGL, come back and start reading the documentation for the GU and the SDK samples.

3D is generally 3D no matter which API you use. The only other decent ones are the GU version of the Nehe tutorials found at psp-programming which you found too hard.

Hey,
I need some help with my program. To put it simple, i made a timer to allow some credit screens to apprear in my loop. For every screen that appears, i want a different music sound effect to play once. Here is my code (i know i completely messed up, but i can't think of how i can make it possible). Right now, the mp3 just repeats itself while i display my first image. Anyways, here is my code:

int credits()
{
int showTime = 0;
Font* myfont1 = Font_Load("./files/Fonts/VERA.TTF");
Font_SetSize(myfont1, 14);        
Font* myfont2 = Font_Load("./files/Fonts/REN_STIM.TTF");
Font_SetSize(myfont2, 15);
Font* myfont3 = Font_Load("./files/Fonts/VERA.TTF");
Font_SetSize(myfont3, 20);
Image* credits;
Image* credits2;
Image* credits3;
credits = loadImage("./files/images/superbatxs.png");
credits2 = loadImage("./files/images/bubbles.png");
credits3 = loadImage("./files/images/superbat.png"); 
           	MP3_Load("./files/sounds/comet1.mp3");
            MP3_Play(); 
            while(1) {
            	for (;;) {
	            showTime++;
                if (showTime < 240) { // EVERY 60 IS A SECOND //    
                blitAlphaImageToScreen(0, 0 , 480, 272, credits, 0, 0);
			    Font_PrintScreen(myfont3, 135, 125, "SuperbatXS presents...", GU_RGBA(0, 100, 0, 255), getVramDrawBuffer());
			    flipScreen();
		                     }
                 }                     
                 if (MP3_EndOfStream() == 1) {
                      MP3_Stop();
                           break;
                 }
            } 	   
            MP3_Stop();

            blitAlphaImageToScreen(0, 0 , 480, 272, credits2, 0, 0);
			Font_PrintScreen(myfont2, 2, 10, "A shell developed for full homebrew", GU_RGBA(0, 0, 255, 255), getVramDrawBuffer());
			Font_PrintScreen(myfont2, 10, 25, "gaming and media experience...", GU_RGBA(0, 0, 255, 255), getVramDrawBuffer());
			flipScreen();		
        }
		if ((showTime > 480 && showTime < 850)){ // EVERY 60 IS A SECOND //  
            blitAlphaImageToScreen(0, 0 , 480, 272, credits3, 0, 0);
            Font_PrintScreen(myfont3, 185, 145, "G-Pack", GU_RGBA(0, 0, 255, 255), getVramDrawBuffer());

           appmain();

Lol, that's obvious. But, i want to load the different music files for each loading screen. For example, my first loading screen blits while playing the music, when the music ends, the next loading screen blits and the next music begins along with it. Now, each of my music file also has a different length.

superbatx, I suggest that you indent. It helps in several ways. It make your source readable, and it allows you to see these kinds of errors easier.

I suggest you use a program called Astyle. It automatically formats your source to be indented in different styles such ANSI, K&R, GNU, etc... It is built in to Code::Blocks.

I also suggest DevC++ due to the fact that it auto indents and other stuff ;p

Look at post #3563. I already indented. SG57 just quoted it without the indents i put. Also, some of the indents i put in that post aren't the way they are.

I need some help with 4th brightness. Here is my code:

void sceDisplay_driver_9E3C6DC6(int 100,int 0);//a0 0-100,a1 = 0/1 (set to 0) 
#define sceDisplaySetBrightness sceDisplay_driver_9E3C6DC6 
void sceDisplay_driver_31C4BAA8(int *100,int *0); 
#define sceDisplayGetBrightness sceDisplay_driver_31C4BAA8

//later in main loop
if (pad.Buttons & PSP_CTRL_LTRIGGER){
sceDisplayGetBrightness(int *100, int *0) 	//to get brightness, and
sceDisplaySetBrightness(int 100, int 0)           //to set brightness
}

I am obviously not using the right functions or the right values. What is the code i need to use if i want to set the 4th brightness?

[BlackShark]

Well I can't help you with the brightness thing but this might give you problems later on...

if (pad.Buttons & PSP_CTRL_LTRIGGER){

that looks like a standard pad hold, do you plan to make it so it Cycles through the brightness levels with the L trigger? if so than I would use the "new_pad" or "old_pad" trick, (what ever ya want to call it) so that it waits for you to lift up the button and press it down again before it changes, other wise it will cycle through really really fast. But if thats not the case than just ignore this post :P

I'd rather use this:

if(pad.Buttons & PSP_BUTTON_SOMEBUTTON)
{
   // do your ****
   function();

   while(pad.Buttons & PSP_BUTTON_SOMEBUTTON)
   {
      sceCtrlPeekBufferPositive(&pad, 1);
   }
}
