Here's the way I do it:
When the mud boots it checks for the stock area header:
#AREA
midgaard.are~
Midgaard~
{ All } Diku Midgaard~
3000 3399
(If it happens to be a stock ROM area with the OLC header, I manually change
the header to look like this)
If it gets this, it flags a boolean (stock) to true.
Then in all my boot functions, wherever something exists not from stock,
it uses the stock method of reading those values.
Example:
if (old_area) {
/* if it's an old area, we need to convert the AFF_FLAGS to ammaross bit
system */
STR_COPY_STR( pMobIndex->affected_by,
aff_convert_fread_flag( stread_flag(str) ), AFF_FLAGS );
}
else {
STR_COPY_STR( pMobIndex->affected_by,
str_stread_flag( str, AFF_FLAGS ), AFF_FLAGS );
}
(There are several of these throughout)
Then asave the area and it's converted.
Also, I added a 'stock' argument to 'asave' to take areas with my format and
convert them back to stock ROM.
Why would you want to do that?
