Random sounds - 02/08/10 15:12

Does sombody know how to make random sounds?
I meen here is a normal sound code:

SOUND* snd_hurt = "hurt_1.wav";

function hit_obj_meat()
{
if (event_type == EVENT_SHOOT)
{
snd_play(snd_hurt,55,0);
}
}

But what if when you whant to use random sounds:

snd_play(snd_hurt1,55,0); or snd_play(snd_hurt2,55,0);

How can I do that?
I only wright in lite-c.

Code:

SOUND** ptr = (SOUND**)malloc(sizeof(SOUND*)*3);
ptr[0] = snd_hurt1;
ptr[1] = snd_hurt2;
ptr[2] = snd_hurt3;
snd_play(ptr[integer(random(3))], 55, 0);
free(ptr);

Thanks, but it crashes or I maby writen it wrong:

SOUND* snd_hurt = "hurt_1.wav";
SOUND** ptr = (SOUND**)malloc(sizeof(SOUND*)*3);

ptr[0] = snd_hurt1;
ptr[1] = snd_hurt2;
ptr[2] = snd_hurt3;

function hit_obj_meat()
{
if (event_type == EVENT_SHOOT)
{
snd_play(ptr[integer(random(3))], 55, 0);
free(ptr);
}
}

well, it won't even compile that way. you first have to declare the snd_hurt1..3 sounds. and the code has to be written inside of a function. i'd advise you to first read some kind of beginners tutorial on coding.

Maybe:

Code:

SOUND*snd1="shdfkdh.wav";
SOUND*snd2="shdfkfsddh.wav";
SOUND*snd3="shdfksdffddh.wav";

function playrandomsound()
{
   random_seed(0);
   wait(1);
   var i=random(2);
   switch(i)
   {
       case 0:
       snd_play(sound1...);
       case 1:
       snd_play(sound2...);
       case 2:
       snd_play(sound3...);
   }
}

@Razoron: That don`t will work, for the switch() you need a integer.

var i=integer(random(3));

Now i can be 0,1 or 2.

Don't you need "break" statements in that switch case? I'm not accustomed to Lite-C, but in real C you have to put break statements at the end of your cases to prevent the program from going through all of them at run time.

Yes.

Razoro, youre code (with the var from Widi) doesen`t work becose of the function
"random_seed(0);", but without "random_seed(0);" there is no sound.
And when I wright it like this;

_______________________________________________________________
SOUND*snd1="shdfkdh.wav";
SOUND*snd2="shdfkfsddh.wav";
SOUND*snd3="shdfksdffddh.wav";

var i=integer(random(3));

function playrandomsound()
{
//deleted//
wait(1);
var i=random(2);
switch(1)//It was "switch(i)"
{
case 0:
snd_play(sound1...);
case 1:
snd_play(sound2...);
case 2:
snd_play(sound3...);
}
}
______________________________________________________________
There should be no warnings.

Blackchuck it doesn`t work.
still thanks

Code:

SOUND*snd1="shdfkdh.wav";
SOUND*snd2="shdfkfsddh.wav";
SOUND*snd3="shdfksdffddh.wav";

function playrandomsound()
{
   var i=integer(random(3));
   switch(i)
   {
      case 0:
      snd_play(sound1...); break;
      case 1:
      snd_play(sound2...); break;
      case 2:
      snd_play(sound3...); break;
   }
}

Now you have to call the function playrandomsound if you want to hear your Sound.

Edit: if "random_seed(0);" don`t work, make a update, it is the newer function from randomize.

that's like:
A: I need something to move heavy objects more easily.
B: Here's the wheel.
A: It crushes.
B: You have to use it with a cart.
C: I've a better solution: Here's the cube.

@Joey: Yes, your solution is the best way, i know. But with the "select" it is better to understand for a beginner i think...

@Blackchuck: If random_seed don`t work, then you don`t have the Version 7.80. As i see in other posts, i think you have a Warez Version.

i was not complaining about it ^^ - it's really nice of you to help people out.

Re: Random sounds - 02/08/10 23:48

why not just use random sounds in an array like Joey said?

Code:

SOUND* snd_random[10]; //create pointer for 10 sounds (0-9)

//...

void play_random_sound(){
   
   int i = random(10);
   snd_play(snd_random[i], 100, 0); //sound, volume, balance
}

void main(){

   snd_random[0] = snd_create("bang.wav");
   snd_random[1] = snd_create("whizz.wav");
   //...
   snd_random[9] = snd_create("pop.wav");

make sure all sounds are in mono, wav or ogg format

*untested* but 'should' work

hope this helps

you have to use integer(i) as index.

Code:

void createNewSnd(STRING* sndStr, int maxNmbr) {
	STRING* tempStr = str_create("");
	int randNum = integer(random(maxNmbr)+1);
	
	str_cpy(tempStr, sndStr);
	str_cat(tempStr, "_");
	str_cat(tempStr, str_for_int(NULL, randNum));
	str_cat(tempStr, ".wav");
	
	SOUND* tempSnd = snd_create(tempStr);
	// play the sound
	var sndHandle = snd_play(tempSnd, 100, 0);
	// wait until finished
	while (snd_playing(sndHandle)) { wait(1); }
	
	// remove the sound
	ptr_remove(sndHandle);
}

you have all your sounds named something like "attack_n.wav", where n is an number from 1 - unlimited.

you call the function like:

Code:

createNewSnd("attack", 5);

And it will get you a random sound chosen from attack_1 .. attack_5.

Tested and works (implemented it in my own game)!

ah damn implicit type conversion

. with a good compiler you'd at least get a warning here ^^.

Widi youre code worked the best, thanks it works now.

Thanks you all, I never say a forum that realey helps so much thanks!
