Sfx file format

[Duotone]

Well. Thats all i could figure out so far. Any help appreciated.

struct quad_data
{
    short unknown1;
    float position_x;   //position vector. added after rotation
    float position_y;
    float position_z;
    float unk1;
    float unk2;
    float unk3;
    float scale_x_OR_cylinder_upper_radius;  //scale_x is for a 2D scaleing (texture's quad)
    float scale_y_OR_cylinder_height;  //2D
    float quad_z_OR_cylinder_bottom_radius;   //Z koordinate to the quad only used by (quad type 4)
    float rotate_x;
    float rotate_y;
    float rotate_z;
    int animation_time; //milisecs
};
//animateing this is easy. you just take the next quad_data from the array, do the wigth-awarage with the current one, and display the result

struct SFX
{
    char version[8];
    int ntextures;
    
    struct sfx_part
    {
        int part_type;  //1 = horizontal quad, 2 = vertical quad, 3 = ???, 4 = cylinder
        if(version[5] > '1')
        {
            int comment_len;
            char comment[ comment_len ];
        }
        int texture_name_len;
        char texture_name[ texture_name_len ];

        short unknown1;
        short unknown2;
        int unknown3;
        int quad_type; //1 = billboard, 2 = horizontal, 4 = vertical
        if(version[5] > '1')
        {
            int unknown5;
        }
        if(part_type == 2)
        {
            byte unknown6[10];
            float q[15];
            if(version[5] >= '2')
            {
                int unknown6_2[8];  //zero?
                float unk_degree;
                int unknown6_3;
                if(version[5] == '3')
                {
                    int unknown6_4;
                }
                float q2[12];
            }
        }

        short n;
        short unknown7;

        quad_data animation_states[ n ];   //these data uses the texture above

        if(part_type == 4)
        {
            int n4;   //divides each cylinder into n4 parts
        }

    } texture_data[ ntextures ];
} sfx;

Oldest one (without SFX0. header)

struct quad_data
{
    short unknown1;
    float position_x;   //position vector. added after rotation
    float position_y;
    float position_z;
    float unk1;
    float unk2;
    float unk3;
    float scale_x_OR_cylinder_upper_radius;  //scale_x is for a 2D scaleing (texture's quad)
    float scale_y_OR_cylinder_height;  //scale_y is 2D
    float quad_z_OR_cylinder_bottom_radius;   //Z koordinate to the quad only used by (quad type 4)
    float rotate_x;
    float rotate_y;
    float rotate_z;
    int animation_time; //milisecs
};


struct SFX
{
    int ntextures;
    
    struct ELEM
    {
        int part_type;  //1 = horizontal quad, 2 = vertical quad, 3 = ???, 4 = cylinder
        int texture_name_len;
        char texture_name[ texture_name_len ];

        short unknown1;
        short unknown2;
        int quad_type; //1 = billboard, 2 = horizontal, 4 = vertical
        if(part_type == 2)
        {
            byte unknown6[10];
            float q[15];
        }
        short n;
        short unknown7;

        quad_data animation_states[ n ];

        if(part_type == 4)
        {
            int n4;   //divides each cylinder into n4 parts
        }

    } texture_data[ ntextures ];
} sfx;

Thanks to Nicco and his mate for the picture shareing site

naisly done duo.

[guardiananqel]

Really Nice !!!!
its perfect x3

[divinepunition]

nice done ^^

In futur i hope we will be able to edit or create our own sfx :p

[MisterKid]

Nice ^^ I'm curious how you find out those things, well if you have time to explain.
A link would be fine to xD

Reverse Engineering i recall?

Reverse Engineering i recall?

ohh :O lets google tuts XD thank you

Reverse Engineering is for medium to advanced programmers. I'm more than sure your programming experience is not enough to advance to this step mate.. Try learning a bit more and getting used to a programming language first.

up ! this thread should be pined with o3d structure and also rgn, res and lnd structures find by xadet too :o

[GlaphanKing]

Good idea. If the format is done, I can pin it in the release section, otherwise I can pin it here for the time being.
