The only thing a CFILE contained was a version field which isn't used
anymore so that could be removed which basically meant that CFILE was
just an indirection to a Cfile_block which I then just renamed to CFILE.
The CFILE type is an opaque handle now since the contents are not
relevant to a user of Cfile.
This allows to use more complex file structures in the executable
without requiring that those exist as real files. The rest of the code
does not need to handle the difference between a default file and a real
file anymore which means that it's now possible to embed image files
into the executable since bmpman only needs to use the standard CFile
API.
I added two tests which check if the default file can be found and
opened and if a mod file overrides the default file which should always
be possible.
Invalid values previously corrupted the internal position counter which
caused crashes on some platforms because the position counter would
overflow in the next read operation. I added some assertions to track
the position counter corruption and it's probably a good idea to leave
them in to catch possible future errors early.
The actual fix was to just ensure that the seek position it always valid
for the file.
This fixes#1059.
- Add On Mission Start, On Mission End hooks; swap Warpin and Warpout to Warp In and Warp Out
- Safer handle helper structs
- Improved math, eg matrix interpolation and vector multiply/divide
- Filesystem read AND write support
- Initial scripting orders support
- Better waypoints support
- Assorted requested scripting functions
bmpman:
- Safer bm_get_filename
cfile:
- Support for RW, rather than just R or W, file modes.
model:
- Safer texture_info struct. Taylor, I know we talked about this, but I realized that it was just a lot better for what it does and it shouldn't be too much trouble to replace with the new system (operations tend to be much more concise and clear). Let me know if any unexpected difficulties arise.
