I thought this plugin could be useful in the english section.

Description:

The plugin uses the BASS library (http://un4seen.com) to work with audio files.

In the plug collected some very useful features not available in SA: MP



Installation:

Windows:
Put the files from the plugins in the plugins folder on the server.

bass.dll file should be placed in the root directory of the server (the ones where the samp-server.exe), or the windows system directory


Linux:
File libbass.so should be put in the folder / lib /, / usr / lib /, / usr / local / lib /.

Add the plug-in in plugins section in SA: MP config.

Include SystemControl.inc to your script.


Use:

Plugin functions:

ClearConsole(); - clears the server console. In Windows, use the call CLS, in Linux - clear


system(file[]); - Launches an external application (on server) and waits for its completion. Returns exit code of the application. In Linux equivalent function WinExec.

WinExec(file[],ShowParam); - launch an external application (on server) without having to wait

In the first argument specifies the path to the application that should run.

ShowParam can be one of constant:

PHP Code:

#define SW_HIDE             0
#define SW_SHOWNORMAL       1
#define SW_NORMAL           1
#define SW_SHOWMINIMIZED    2
#define SW_SHOWMAXIMIZED    3
#define SW_MAXIMIZE         3
#define SW_SHOWNOACTIVATE   4
#define SW_SHOW             5
#define SW_MINIMIZE         6
#define SW_SHOWMINNOACTIVE  7
#define SW_SHOWNA           8
#define SW_RESTORE          9
#define SW_SHOWDEFAULT      10
#define SW_FORCEMINIMIZE    11
#define SW_MAX              11 


In the Linux version is a wrapper function over the system, in which case the argument is ignored ShowParam

More information about the work function can be read on MSDN: http://msdn.microsoft.com/en-us/libr...(v=vs.85).aspx

Fixed:
Sleep(milliseconds); - suspends the execution of an application for a specified number of milliseconds

Can be used with multithreading plug-ins.
In Linux uses usleep

http://msdn.microsoft.com/en-us/libr...(v=vs.85).aspx


GetCursorPos(&x,&y); - get the position of the cursor on the screen (the server)

Return the position of the cursor on the server.
In linux returns 0.

http://msdn.microsoft.com/en-us/libr...(v=vs.85).aspx


GetAudioURLFileLengthSec(URL[]); - returns the length of the audio stream in seconds
GetAudioURLFileLengthBytes(URL[]); - returns the length in bytes of the audio stream

Uses BASS library. Gets the length of the audio stream or file from the server.
If the stream does not have the length function returns -1, otherwise returns GetAudioURLFileLengthSec length in seconds, GetAudioURLFileLengthBytes in bytes.

ListDirs(path[]); - dirs listing in current path. Call OnListDir if dir founded.

Example:

PHP Code:

public OnFilterScriptInit()
{
           ListDirs("."); 
    return 1;
}

public OnListDir(dir[])
{

    new string[35];
    format(string,sizeof(string),"Found dir: %s",dir);
    print(string);
    return 1;
} 


ListFiles(path[]); - files listing in current path. Call OnListFile if file founded.

Example:

PHP Code:

public OnFilterScriptInit()
{
           ListFiles(".");
    return 1;
}

public OnListFile(file[])
{

    new string[35];
    format(string,sizeof(string),"Found file: %s",dir);
    print(string);
    return 1;
} 


Example filterscript

PHP Code:

#include <a_samp>
#include "SystemControl"

public OnFilterScriptInit()
{
    WinExec("notepad.exe",SW_NORMAL);//Run Notepad (only windows)

    new string[35];
    format(string,sizeof(string),"Stream Length: %d Seconds",GetAudioURLFileLengthSec("http://listen.radio-mixer.ru:8000/DNB")); //return -1, because stream does not have the length
    print(string); 

    format(string,sizeof(string),"Stream Length: %d Seconds", GetAudioURLFileLengthSec("http://upload.wikimedia.org/wikipedia/ru/4/4d/Omen.ogg")); //return 35 seconds.
    print(string);

    return 1;
}

public OnPlayerText(playerid,text[])
{
    return 1;
}

public OnPlayerUpdate(playerid)
{
    ClearConsole(); //Clear the console window

    new x, y;
    GetCursorPos(x,y); //x,y contain cursor position

    new string[35];
    format(string,sizeof(string),"X:%d Y:%d",x,y);

    print(string);

    return 1;
} 


Callbacks:
public OnListDir(dir[])
public OnListFile(file[])

Useful const:
Math:

PHP Code:

 * M_E        - e
 * M_LOG2E    - log2(e)
 * M_LOG10E   - log10(e)
 * M_LN2      - ln(2)
 * M_LN10     - ln(10)
 * M_PI       - pi
 * M_PI_2     - pi/2
 * M_PI_4     - pi/4
 * M_1_PI     - 1/pi
 * M_2_PI     - 2/pi
 * M_2_SQRTPI - 2/sqrt(pi)
 * M_SQRT2    - sqrt(2)
 * M_SQRT1_2  - 1/sqrt(2)

Sorry for my bad English.

[Gamer_Z]

I'm kinda wondering how everyone is going to use this to exploit hosters...

GetCursorPos(&x,&y); - Awesome!

[Mauzen]

Well, it still cant do more than the permissions allow, so as long as the hosters set everything up properly nothings going to be exploited

Anyways, nice plugin, im quite sure that some people can make good use of system executions.

[TheArcher]

How can i use GetCursorPos if the cursor is hidden? btw good job

Kinda Good Job

[jhonyxakep]

How can i use GetCursorPos if the cursor is hidden

This function works only on Windows, but if the cursor is hidden, it will still have a position

This plugin makes no sense.

Why? You do not like the source plug-in?

What is it used for? You can't see the arrow and you just get a random coords for your cursor.

cell AMX_NATIVE_CALL n_Sleep

You actually know that this will stop the whole server for the amount of miliseconds?

Also, em, Sleep(miliseconds) != usleep(miliseconds * 100).

microseconds to miliseconds conversion goes actually by x 1000... not x 100.
