How? Could you show me?

Replace the first 0 in sceKernelCreateThread with PSP_THREAD_ATTR_USER.

[SuperBatXS]

Oh, i tried that. But now, when i click X on yes, it says please wait...but does not exit the app (freezes). Thanks for trying to help me, but i am going to put my app back into user mode though.

[Blackbelttcon]

im having some problems trying to ,after i open a file, make the string of text in it into a variable that i can use anytime, even after the files is closed.


here is my code for opening the file.

 // Opens pass
  {
 	ifstream OpenFile("pass.conn");

	char pass;
	while(!OpenFile.eof())
	{
		OpenFile.get(pass);
		cout <<  pass;
	}

   }

Hey,
I have created a timer for shooting bullets. However, how do i put multiple bullets? Do i need an array? Do i need to blit the bullet more than once (obviously, since there are more than one, but still...)?
Btw, my current code (for one bullet on screen) is very smooth and works great.

omg thanx ive been working on that for about 10 hours now and havent found anything till now.


thanx if i could donate, i would :Punk:

Btw, here's my current bullet code (works flawlessly). But i need to find out how to shoot multiple bullets.

//Square
if (pad.Buttons & PSP_CTRL_SQUARE)
{
   //Shoot
   FireTimer++;
}

/*******************
    Shooting
********************/
//Fresh Shot Ready
if (FireTimer < 1)
{
WeaponPosX = SpaceshipPosX + SpaceshipWidth;
WeaponPosY = SpaceshipPosY + 15;
FireTimer = 0;
}

//Active Shoot
if (FireTimer > 1) {    
   if (FireTimer < 4) { WAV_Play(fire1); }             
   blitAlphaImageToScreen(0, 0, WeaponWidth, WeaponHeight, Weapon, WeaponPosX, WeaponPosY);
   FireTimer++;
   WeaponPosX += WeaponSpeed;
}

//Refresh Shooting
if (FireTimer > WeaponDistance)
{
WeaponPosX = SpaceshipPosX + SpaceshipWidth;
WeaponPosY = SpaceshipPosY + 15;
FireTimer = 0;
}

Think 'for' loop,
for (i = 1; i <= active_bullets; i++)
{
if (bullet[i].active)
{

}
}
etc

I'm sure there's a more productive way of doing it, but that's one way.

[SuperBatXS]

Just posted my current code. Anything wrong with it?

[Blackbelttcon]

when i run the program the variables pass comes out with a line and a half of spaces after it. how do i get rid of that.

Gets the variable from the Conn file

     // Opens pass
  {
 	ifstream OpenFile("pass.conn");

	char pass1;
	while(!OpenFile.eof())
	{
		OpenFile.get(pass1);

         pass += pass1;
	}

   }

this is were the line and a half of spaces comes after this is your password=

     cout << " this is your password= " << pass <<endl;

[SuperBatXS]

Think 'for' loop,
for (i = 1; i <= active_bullets; i++)
{
if (bullet[i].active)
{

}
}
etc

I'm sure there's a more productive way of doing it, but that's one way.

I'm still confused. What are you trying to say?

[Slasher]

Well make your bullets into a struct, then use a for loop to go through them and draw them, update them, etc.

#define MAX_BULLETS 128

typedef struct
{
	int x, y;
	int speed;

	int active;

} bullets[MAX_BULLETS];

int curBullet = 0;

// Before your loop
int i;
for (i = 1; i <= MAX_BULLETS; i++)
	bullets[i].active = 0;

// In your code
int i;
for (i = 1; i <= MAX_BULLETS; i++)
{
	if (bullets[i].active)
	{
		// Update (Your 'Refresh Shooting' section)
		bullets[i].x += bullets[i].speed;
		
		// Draw
		blitAlphaImageToScreen
	}
}

// Button press (You might want to put a delay on this)
if (pad.Buttons & PSP_CTRL_SQUARE)
{
	if (curBullet < MAX_BULLETS)
		curBullet++;
	else
		curBullet = 1;

	bullets[curBullet].active = 1;
	bullets[curBullet].x = xvalue;
	bullets[curBullet].y = yvalue;
	bullets[curBullet].speed = speedvalue;
}

Hopefully you get the jist of it through that. You'll want to 'deactivate' the bullet after a set time, or perhaps if it goes off the screen. Just keep track of the x value through that for loop.

i need help hope someone can help me out.

this is how i would read 10 characters in a string from test file:

char mystring [5];
pFile = fopen ("ms0:/test.txt" , "r");
fgets (mystring , 5, pFile);
puts (mystring);
fclose (pFile);

but how would i set a own string for each of the 5 characters inside the txt ??? :Argh:


also is it possible to merge 5 variables in one string?
need to merge all 5 together in one string which i can compare laters.

mychar[0] = 0;
mychar[1] = 0;
mychar[2] = 0;
mychar[3] = 0;
mychar[4] = 0;
mychar[5] = 0;


thanks

As for your first question, you don't need to. To access the first character, use mystring[0]. For the second, use mystring[1], etc. Also, if you're reading 5 characters, it should be mystring[6] for the null terminator. And as for your second, use sprintf.

char buf[20];
sprintf(buf,"%i %i %s",mychar[2],mychar[5],mystring);

It's easy :)

char buf[6];
void ReadFile(const char *filename)
{
  
  FILE *read = fopen(filename, "r");
  sprintf(buf, "%s", fgets(buf, 6, read));
  fclose(read);
}

Then, check characters of the buf using...

// Example
if(strcmp(buf[0], "a") == 0)
// ...

or...

// Another example xD
if(buf[0] == 0x20)
// ...

Cheers :)

Except that strcmp() expects a string, and not a char.

[Mr305]

Don't complain, I've been asking for a few days about how to load a pspbtcnf file, and no reply...

I've got this so far, I basically copied from the 3.40OE-A source code, and commented out the stuff I didn't need, but no luck:

    struct SceKernelLoadExecVSHParam param;
    //u32 vshmain_args[0x20/4];

    memset(&param, 0, sizeof(param));
    //memset(vshmain_args, 0, sizeof(vshmain_args));

    //vshmain_args[0/4] = 0x0400;
    //vshmain_args[4/4] = 0x20;
    //vshmain_args[0x14/4] = error;

    param.size = sizeof(param);
    //param.args = 0x400;
    //param.argp = vshmain_args;
    //param.vshmain_args_size = 0x400;
    //param.vshmain_args = vshmain_args;
    param.configfile = "/kn/pspbtcnf_p4bu.bin";

Am I missing something blindingly obvious?

hey, i wqas just wondering if anyone knows if there has been a program that hides/blocks homebrew games like there is for videos/pictures?

[FaT3oYCG]

hello world

well i have finally got my cygwin/psptoolchain/some libs working and i can now compile luaplayer 0.20 - the others have one or two problems but it is just one line that i haven't bothered to change

anyway i was just wondering which libs i need to compile the luaplayer when mp3 and ogg have been added in

basically which libs contain the mp3 and ogg

thanks

[Xsjado7]

Discard previous post.

Anyways, i was wondering if anyone knew a library i could use to load .WAV's. I've previously used OSLib but now i've moved away from it and WAVLoader gets a stack of errors for me when compiling even the samples. Any help would be great
-= Double Post =-
by previous post i mean mine, not FaT3oYCG

@FaT3oYCG Isnt ogg playback already in LUAPlayer?

[FaT3oYCG]

not sure but anyway i would like to be able to compile my own version of the lua player with mp3 support at least which im sure requires a library that i haven't installed yet and i would just like to know which one that it is thanks

[Xsjado7]

i thought it had mp3 as well

[Judas]

not sure but anyway i would like to be able to compile my own version of the lua player with mp3 support at least which im sure requires a library that i haven't installed yet and i would just like to know which one that it is thanks

Cools Mod #4 already has MP3 and OGG support.

[Xsjado7]

i thought so

[FaT3oYCG]

hmm i probably didn't explain properly

- i want to be able to compile cools mod 4 with my cygwin and was asking which libs that i would need please

thanks

sorry for the long reply

im integrating pikey into lua player

its quite easy dont know why it hasn't been done and released before

thanks again

Craig

[Anti-QuickJay]

im guessing an error saying mad means you need to install libmad

Im guessing you'll need mikmod for it support.

Remember this is all guess work. Doesnt the makefile tell you which libs ?

Not exactly of what you mean by "'Load' a new one".

If you are already able to edit one, replace the old one with the edited one on flash0,0.

or
Is it a problem of 3.xx flashing?
