Vibra, Data, Midi
 

Hello,
I almost finished my greatest invention, but i still need some things:

1. How to unleash vibra? Are there any special libs? Or just commands?
2. How to save data to a file? (to make high score or config file)
3. How to play MIDI music or MIDI sound effects from files?

Thanks

1) Lib_vibra
function Vibrate(integer i); //i millisec
2) Lib_Resloader

3)Учи Великий и Могучий )))

Lib_resloader hasn't functions for saving data, it only can load data from resources.

If you need to save data to the phone's file system, you should use Lib_jsr75. Note, that using this library you may get a lot of troubles with different filesystems, security settings, etc.
If you need use saved data only in your midlet, it will be better to use RecordStore, that allow you easily save your data to the system registry independently of phone model and security policy. To get information about RecordStore, refer to standard MP help.

Thanks.

About problem 2. Can I just write:

OpenPlayer('/music.mid'
StartPlayer;
StopPlayer;
?


And Vint, does saving highscore in registry can be dangerous to phone? (i mean - can it mess up something?)

You should just write
and playing wil be started.
To stop player (i.e. by a timer) you should call StopPlayer.

No, it is completely safe, because data is written to the local midlet's registry and don't influence on the system or another midlets.

Vibra works fine, thanks.

Sound system works but.. it slows down an application greatly. I mean, my midi file consist of 1 note only (it's 114B ) but each time the program reaches the sound command, it stops for about 0.5s to load it. It makes game unplayable. The problem appears in both phone and KEmulator. Any hints?

Do you load file once, or you use OpenPlayer every time, when you call StartPlayer?

Ответ: Vibra, Data, Midi
 

Actually i'm using OpenPlayer every time, because i'd like to play more than just one type of MID, and it looks like there are not.. "bufforing system" here to predefine all files before gaming. But i might be wrong..

If you have not too much sounds, try to use Lib_player. It allow you to load some sounds simultaneously, and play any of it at the necessary time (even simultaneously, if phone supports audio mixing) without large delays .

Sounds exactly what i am looking for. Where can i get it?

The library is here

After some experimenting i still can't figure out, how to this thing works. I'm basing on this example i found inside the zip:

program test11111;
uses player;
procedure player_event(p:integer; e:String);
begin
Debug(e+':'+p);
end;
begin
player.init(2);
if not OpenPlayer('/message.mid', 'audio/midi') then Halt;
if not SetPlayerCount(-1) then Halt;
player.set_listener;
if not StartPlayer then Halt;

player.select(1);
if not OpenPlayer('/online.mid', 'audio/midi') then Halt;
if not SetPlayerCount(-1) then Halt;
player.set_listener;
if not StartPlayer then Halt;

Delay(5000);

drawText('Hello world!', 0, 0);
repaint;
delay(2000);
end.


And hell.. Don't get it. What is the point of 'player_event' procedure if it's never called? And why sim doesn't run when I remove it? Also which commands are responsible for loading files, which for declaring vars, and which for calling? What is .set_listener? I'm sorry but i will need some more clues or something.. easier to use.

Could u give another example please? And point 'this is were we load files', 'this is were we name vars' and 'this is how we call previously redefined sounds'..

Pls help.

The player_enevt proc is an event handler and is called by the library if any player event, like end of media, occur. It should NOT be renamed or removed, becaus it cause application error.

In the beginning we mus initialize the library, defining necessary count of players (equals to the count of sounds)
init(n); n - players count
after this operation library is initialized, and player, assigned with index "0" is selected.

After that, any standard player function (OpenPlayer, StartPlayer, SetPlayerCount will be applied to it, so, writing
if not OpenPlayer('/message.mid', 'audio/midi') then Halt; we load the file to the player "0". Calling set_listener, we assign event handler (the player_event proc) to this player.

To work with another player(1..n-1) we should call player.select(i), where i is index of the necessary player, after that all functions will be applied to player, indexed as "i" (but event handler continues to work for any player, for which set_listener was called).

Success!:super: Sound system works.

However, after implementing sounds to the midlet the "MIDletPascal" application itself crash sometimes when I press 'build' right after 'save'. But it's nothing. I just have to turn on the application again, and at second time 'build' button works. Pretty odd however.

Thanks.

So all it's left for now it's highscore storage. First I'll try to figure it out by myself..
