[CoD] File Formats

[kung foo man]

Hey Serthy, sorry for late respone, I didn't see your answer in the other thread for some reason.

I tried to port your code to C# and it works so far, but I wonder how to "read the pixels" now, like "RGBA color = iwi.getPixel(x,y)". This is what I got so far:

		using UnityEngine;
using System.Collections;
using System; // System.Byte etc.

public class HEADER
{
    public Byte start_I;
    public Byte start_W;
    public Byte start_i;
    public Byte version;
    public Byte DXTformat; //0x0b -> DXT1? | 0x0d -> DXT5?
    public Byte flag;
    public UInt16 width;
    public UInt16 height;
    public UInt16 u3;
    public UInt32[/*4*/] lol;

    public HEADER(System.IO.BinaryReader binaryReader)
    {
        start_I = binaryReader.ReadByte();
        start_W = binaryReader.ReadByte();
        start_i = binaryReader.ReadByte();
        version = binaryReader.ReadByte();
        DXTformat = binaryReader.ReadByte(); //0x0b -> DXT1? | 0x0d -> DXT5?
        flag = binaryReader.ReadByte();
        width = binaryReader.ReadUInt16();
        height = binaryReader.ReadUInt16();
        u3 = binaryReader.ReadUInt16();
        lol = new UInt32[4] {
            binaryReader.ReadUInt32(),
            binaryReader.ReadUInt32(),
            binaryReader.ReadUInt32(),
            binaryReader.ReadUInt32()
        };
    }

    public int getVersion()
    {
        if( start_I != 73 || start_W != 87 || start_i != 105 )
            return 0;
        else if( version != 0x05 )
            return -2;
    
        int DXTVERSION = 0;

        if( DXTformat == 0x0b )
            DXTVERSION = 1;
        else if( DXTformat == 0x0d )
            DXTVERSION = 5;
        else
            return -3;

        if( u3 != 1 )
            return -4;
        else if( flag != 1 && flag != 0 )
            return -5;

        return DXTVERSION;
    }
}

public class COLORBLOCK
{
    public UInt16 color0;
    public UInt16 color1;
    public Byte[/*4*/] index;

    public COLORBLOCK(System.IO.BinaryReader binaryReader_)
    {
        color0 = binaryReader_.ReadUInt16();
        color1 = binaryReader_.ReadUInt16();
        index = binaryReader_.ReadBytes(4);
    }
}

public class DXT1
{
    public COLORBLOCK cb;

    public DXT1(System.IO.BinaryReader binaryReader_)
    {
        cb = new COLORBLOCK(binaryReader_);
    }
}

public class DXT3
{
    public Byte[/*8*/] alpha;
    public COLORBLOCK cb;
}

public class DXT5
{
    public Byte alpha1;
    public Byte alpha2;
    public Byte[/*6*/] alpha_indices;
    COLORBLOCK cb;
}

public class IWI
{
    HEADER header;
    System.IO.BinaryReader binaryReader;

    public IWI(System.IO.BinaryReader binaryReader_) {
        binaryReader = binaryReader_;

        header = new HEADER(binaryReader);
        int numMipmaps = getMipmapCount( header.width , header.height );
    
        Debug.Log("numMipmaps: " + numMipmaps + " size="+header.width + "/"+header.height + " version=" + header.getVersion());

        while( numMipmaps > 0 )
        {
            numMipmaps--;
            readMipmap( getSize( header.width >> numMipmaps , header.height >> numMipmaps , 4 ) );
        }
    }

    int getSize(int width, int height, int depth)
    {
        return ( ( width + 3 ) / 4 ) * ( ( height + 3 ) / 4 );// * ( DXTVERSION == 0 ? 8 : 16 );   
    }

    int getMipmapCount(int width, int height)
    {
        int max = width > height ? width : height;
        int count = 0;
        int i = 0;

        for( i = 0 ; max >> i > 0 ; i++ )
        {
            count++;
        }

        return count;
    }

    DXT1[] dxt1;

    void readMipmap(int count)
    {
        int DXTVERSION = header.getVersion();

        dxt1 = new DXT1[count];
        for (int i = 0; i < count; i++)
            dxt1[i] = new DXT1(binaryReader);

        Debug.Log("num of dxt1=" + dxt1.Length);

        //if( DXTVERSION == 1 )
        //    DXT1 blocks[count];
        //else if( DXTVERSION == 3 )
        //    DXT3 blocks[count];
        //else if( DXTVERSION == 5 )
        //    DXT5 blocks[count];
    }
}

public class iwi2dds : MonoBehaviour {
    KILLTUBE.GreatExplorer explorer = new KILLTUBE.GreatExplorer();
    IWI iwi;

    void Start () {
        explorer.AddArchive(@"G:\GAMES\CoD2 1.3\main\iw_08.iwd");
        System.IO.BinaryReader binaryReader = explorer.GetGreatFile("images/155_cannon.iwi");
        iwi = new IWI(binaryReader);
    }
} 
	

Output:



(I hope thats correct so far xD)
