multi-dimensional arrays && structuring arrays

Hedgehog Fog · **Author**

Hey there,
I have some problems now, I decided to use structs in Pawn, but encounter a problem, Working with arrays in Pawn very strange.
I try to struct my data:

PHP Code:


			
//Just make some struct:
enum myStruct
{
    _myString,
    _myStringArray[4]
};

//Ok, let's try to use it:
new const myArray[][myStruct][128] =
{
    {
        "Class 1",
        
        {
            "Some data 1",
            "Some data 2",
            "Some data 3",
            "Some data 4"
        }
    },
    
    {
        "Class 2",
        
        {
            "Some data 1",
            "Some data 2",
            "Some data 3",
            "Some data 4"
        }
    }
}

error: 052: multi-dimensional arrays must be fully initialized

Ok, try to fix it

PHP Code:


			
new const myArray[2][myStruct][128] =
{
    {
        "Class 1",
        
        {
            "Some data 1",
            "Some data 2",
            "Some data 3",
            "Some data 4"
        }
    },
    
    {
        "Class 2",
        
        {
            "Some data 1",
            "Some data 2",
            "Some data 3",
            "Some data 4"
        }
    }
}

Hm, what?

Ok, I have some idea, If we have to use constants and fully initialized we can use "double struct":

PHP Code:


			
enum myStructSlots
{
    _slot1[128],
    _slot2[128],
    _slot3[128],
    _slot4[128]
};

enum myStruct
{
    _myString[128],
    _myStringArray[myStructSlots]
};

new const myArray[2][myStruct] =
{
    {
        "Class 1",
        
        {
            "Some data 1",
            "Some data 2",
            "Some data 3",
            "Some data 4"
        }
    },
    
    {
        "Class 2",
        
        {
            "Some data 1",
            "Some data 2",
            "Some data 3",
            "Some data 4"
        }
    }
};

OMG! THANKS! PAWN!

Wait...

PHP Code:


			
log_amx("[%s]", myArray[0][_myString]);
log_amx("[%s]", myArray[0][_myStringArray][_slot1]);
log_amx("[%s]", myArray[0][_myStringArray][_slot2]);
log_amx("[%s]", myArray[0][_myStringArray][_slot3]);
log_amx("[%s]", myArray[0][_myStringArray][_slot4]);

log_amx("[%s]", myArray[1][_myString]);
log_amx("[%s]", myArray[1][_myStringArray][_slot1]);
log_amx("[%s]", myArray[1][_myStringArray][_slot2]);
log_amx("[%s]", myArray[1][_myStringArray][_slot3]);
log_amx("[%s]", myArray[1][_myStringArray][_slot4]);

Quote:

Something bad... I think... "Some data 1" has 11 charmax, just try:

PHP Code:


			
log_amx("[%s]", myArray[0][_myString]);
log_amx("[%s]", myArray[0][_myStringArray][_slot1]);
log_amx("[%s]", myArray[0][_myStringArray][_slot1][12]);

Quote:

[Class 1]
[Some data 1]
[Some data 2]

Try to fix:

PHP Code:


			
enum myStructSlots
{
    _slot1,
    _slot2,
    _slot3,
    _slot4
};

enum myStruct
{
    _myString,
    _myStringArray[myStructSlots]
};

new const myArray[2][myStruct][128] =
{
    {
        "Class 1",
        
        {
            "Some data 1",
            "Some data 2",
            "Some data 3",
            "Some data 4"
        }
    },
    
    {
        "Class 2",
        
        {
            "Some data 1",
            "Some data 2",
            "Some data 3",
            "Some data 4"
        }
    }
};

Maybe multidimensional array so multidimensional? Try to use few arrays:

PHP Code:


			
enum myStructSlots
{
    _slot1,
    _slot2,
    _slot3,
    _slot4
};

enum myStruct
{
    _myString,
    _myStringArray[myStructSlots]
};

new const myArray1[myStruct][128] =
{
    "Class 1",
    
    {
        "Some data 1",
        "Some data 2",
        "Some data 3",
        "Some data 4"
    }
};

Ok.

PHP Code:


			
enum myStructSlots
{
    _slot1[128],
    _slot2[128],
    _slot3[128],
    _slot4[128]

I don't need slots for first value, but maybe it's fix?

PHP Code:


			
enum myStruct
{
    _myString[myStructSlots],
    _myStringArray[myStructSlots]
};

new const myArray1[myStruct] =
{
    {
        "Class 1",
        "NULL",
        "NULL",
        "NULL"
    },
    
    {
        "Some data 1",
        "Some data 2",
        "Some data 3",
        "Some data 4"
    }
};

PHP Code:


			
log_amx("[%s]", myArray1[_myString][_slot1]);
log_amx("[%s]", myArray1[_myStringArray][_slot1]);
log_amx("[%s]", myArray1[_myStringArray][_slot1][13]);
log_amx("[%s]", myArray1[_myStringArray][_slot2]);

Nope...

Oh, I fixed it!

PHP Code:


			
enum myStruct
{
    _myString,
    _myStringArray
};

new const myArray1[myStruct][4][128] =
{
    {
        "Class 1", 
        "", 
        "", 
        ""
    },
    
    {
        "Some data 1",
        "Some data 2",
        "Some data 3",
        "Some data 4"
    }
};

PHP Code:


			
log_amx("[%s]", myArray1[_myString][0]);
log_amx("[%s]", myArray1[_myStringArray][0]);
log_amx("[%s]", myArray1[_myStringArray][0][13]);
log_amx("[%s]", myArray1[_myStringArray][1]);

Quote:

[Class 1]
[Some data 1]
[]
[Some data 2]

...but first values are empty, try this:

PHP Code:


			
new const myArray1[myStruct][][128] =
{
    {
        "Class 1"
    },
    
    {
        "Some data 1",
        "Some data 2",
        "Some data 3",
        "Some data 4"
    }
};

error 018 initialization data exceeds declared size

If I initialize first array of array like:

PHP Code:


			
{
 "Class 1", "", "", ""
}

I have only 4 slots for next arrays of array.

Time to use enum again:

PHP Code:


			
enum myStruct
{
    _myString,
    _myStringArray[4]
};

new const myArray1[myStruct][128] =
{
    "Class 1",
    
    {
        "Some data 1",
        "Some data 2",
        "Some data 3",
        "Some data 4"
    }
};

Any ideas?

You should never have a dimension declared after your use your 'myStruct' enum. Also, strings in Pawn are arrays of characters. I'm guessing it should be like this:

Code:

enum myStruct
{
    _myString,
    _myStringArray[4][32]
};

new const myArray1[myStruct] =
{
    "Class 1",
    
    {
        "Some data 1",
        "Some data 2",
        "Some data 3",
        "Some data 4"
    }
};

**Bugsy** · 03-19-2015 , 19:54 Re: multi-dimensional arrays && structuring arrays

PHP Code:


			
enum myStruct

{

    _myClass[ 7 ],

    _myString1[ 5 ],

    _myString2[ 5 ],

    _myString3[ 5 ]

};



new const myArrays[ 3 ][ myStruct ] =

{

    {

        "Class1",

        "abc1" , 

        "def1" , 

        "ghi1",

    },

    {

        "Class2",

        "abc2", 

        "def2", 

        "ghi2",

    },

    {

        "Class3",

        "abc3", 

        "def3", 

        "ghi3"

    }

};

fysiks,
True, but enum can't contain multi-dimensional arrays. Look at 3 code version at first post.

Bugsy,
I need another struct with path like this:

PHP Code:


			
classID/classname/chars

PHP Code:


			
classID/classdata/dataID/chars

Quote:

PHP Code:


			
new const myArrays[ 3 ][ myStruct ]

Can be dynamic:

PHP Code:


			
new const myArrays[][myStruct]

I showed you how this can be done. Just follow the same format.

Yes, I know.

This isn't what I need, actually.
I know about this method, it is simple. I need a more advanced structure, with path, like path in my last post.

It should be a resource class, like:

PHP Code:


			
new const myClass[myStruct][128]
{
    "classname",
    
    //values for data 1
    {
        "data1_1",
        "data1_2",
        "data1_3",
        "data1_4"
    },
    
    //values for data 2
    {
        "data2_1",
        "data2_2",
        "data2_3",
        "data2_4"
    }
}

where data will be used as:

PHP Code:


			
new sizeData1 = sizeof myClass[_myStringArray1];
new sizeData2 = sizeof myClass[_myStringArray2];

new classname[] = myClass[_myStringArray1][_myString];
new data1[] = myClass[_myStringArray1][random(sizeData1--)];
new data2[] = myClass[_myStringArray2][random(sizeData2--)];

Pawn is a pretty basic language, I'm not sure if what you want is doable. Possibly with macros/hacks.

Hedgehog Fog · *Last edited by Hedgehog Fog; 03-19-2015 at 21:05.*

PHP Code:


			
enum myStruct
{
    _myString,
    _myStringArray
};

new const myArray1[myStruct][4][128] =
{
    {
        "Class 1", 
        "", 
        "", 
        ""
    },
    
    {
        "Some data 1",
        "Some data 2",
        "Some data 3",
        "Some data 4"
    }
};

This is a good way, but initialize an empty slots not the best idea.

PHP Code:


			
enum myStruct
{
    _myString,
    _myStringArray[4]
};

new const myArray1[myStruct][128] =
{
    "Class 1",
    
    {
        "Some data 1",
        "Some data 2",
        "Some data 3",
        "Some data 4"
    }
};

I don't know why it doesn't work and why I got error:

error: 052: multi-dimensional arrays must be fully initialized

May be there is a way to optimize the code of the first version and dont use this if I have 20 slots:
