How to initialize a field object? and a 2D matrix? (basics)

[serthy]

1.
Your array fields are structs, so you have to initialize it before you use it:

array = [];
array[array.size] = spawnStruct();
array[array.size - 1].key = value;

You can initialize an array even without =[] by just calling an index, CoD2 does the rest for you:

array[0] = spawnStruct();
array[0].key = value;

2.

You have to create the matrix yourself:

matrix = [];

for( rowID = 0 ; rowID < rowNum ; rowID++ )
{
    matrix[rowID] = [];

    for( colID = 0 ; colID < colNum ; colID++ )
    {
        matrix[rowID][colID] = spawnStruct();
        matrix[rowID][colID].key = value;

        // better way (so CoD2 doesnt access the matrix each call):
        struct = spawnStruct();
        struct.key = value;
        struct.do_stuff_here_with_struct = instead_of_the_matrix_field;
        matrix[rowID][colID] = struct;
    }
}
