From file i want to extract some data which are saved in scheme as below:

PHP Code:

    1
    {
        1, 2, 3, 4, 1.5
        3, 5, 1, 7, 1.5
        1, 1, 5, 3, 5.0
    }
    2
    {
        3, 1, 2, 5, 0.0
    }
    3
    {
        6, 3, 2, 13, 1.5
        7, 5, 53, 32, 1.5
    }
    4
    {
        64, 1, 2, 1, 0.0
    } 


Now i want to keep it in Dynamic Arrays.

Numbers of data, and entries in data this always will be randomly. so how to save this?
Maybe some datapacks?

[grs4]

So.. if someone will have common problem, here is a solution.

PHP Code:


new Array:g_Array;

public plugin_init()
{
   g_Array = ArrayCreate(1, 50); 50 is max data
} 


before loading our data:

PHP Code:

new Array:aTempArray = ArrayCreate(1, 5); //5 is max entries in every data 


at entry load

PHP Code:

new DataPack:entryInfo = CreateDataPack();
WritePackCell(entryInfo, valueA);
WritePackCell(entryInfo, valueB);
WritePackCell(entryInfo, valueC);
WritePackCell(entryInfo, valueD);
WritePackFloat(entryInfo, valueE);
                
ArrayPushCell(aTempArray, waveRoundInfo); 


at new data load

PHP Code:

ArrayPushCell(g_Array, aTempArray);
aTempArray = ArrayCreate(1, 5); 


And if you want to load all data from arrays

PHP Code:


public readConfig()
{
    new size1 = ArraySize(g_Array);
    for(new i = 0; i < size1; i++)
    {
        new Array:array = ArrayGetCell(g_Array, i);
        new size2 = ArraySize(array);
        
        log_amx("Data %d", i+1);
        
        for(new j = 0; j < size2; j++)
        {
            new DataPack:pack = DataPack:ArrayGetCell(array, j);
            ResetPack(pack);
            log_amx("entry: %d / %d", j+1, pack);
            for(new k = 0; k < 5; k++)
            {
                if(k != 4)
                {
                    log_amx("%d: %d", k+1, ReadPackCell(pack));
                }
                else
                {
                    log_amx("%d: %0.2f", k+1, ReadPackFloat(pack));
                }
            }
            DestroyDataPack(pack);
        }
    }
} 


result:

PHP Code:


L 03/02/2017 - 18:04:02: [lw.amxx] Data 1
L 03/02/2017 - 18:04:02: [lw.amxx] entry: 1 / 1

L 03/02/2017 - 18:04:02: [lw.amxx] 5: 0.00 


And also remember to delete all at plugin end, if you dont do this, server will be crashed at every map change. (Because datapacks are in memory)

PHP Code:

public plugin_end()
{
    new size1 = ArraySize(g_Array);
    
    for(new i = 0; i < size1; i++)
    {
        new Array:array = ArrayGetCell(g_Array, i);
        new size2 = ArraySize(array);
        
        for(new j = 0; j < size2; j++)
        {
            new DataPack:pack = DataPack:ArrayGetCell(array, j);
            DestroyDataPack(pack);
        }
        ArrayDestroy(array);
    }
    
    ArrayDestroy(g_Array);
} 


For me, is very bad, that I Have to know size of DataPack, there is no something like "DataPackSize" and "DataPackGetType" (<- This should return a type of data in current position.

[yas17sin]

this should be in Code Snippets :/.

[Arkshine]

Using another Array to handle an array (since you have a fixed number of values, 5) seems more suit than using datapack here.

[grs4]

With datapacks are more troubles than i knew it can be.

All datapacks which i'm creating has always 5 values
when i want to read a value from postion no. 1

    return info == DATA_VALUE_FLOAT ? ReadPackFloat(pack) : ReadPackCell(pack);
} 


Also, as you told I changed from DataPacks to Arrays. Now everything works great. But i'm interesting in this problem, what is causing it. Why i changed postion to "9" when it should set to "1"

[Arkshine]

Because you don't read the documentation. You misunderstand SetPackPosition(), it expects a value from GetPackPosition(), not an arbitrary index. It might be confusing, we should probably do like SourceMod (they have the same api) and adding a tag for position to both natives.

read I read.
Apperantly I did not undestood. Thanks a lot for help
