Hey... this is pretty good!
Zip writer for GameMaker
A downloadable extension
This small extension allows you to create Zip archives from GameMaker games.
GMS2 version uses the recently added buffer_compress function and is GML-only (so should work on all native platforms).
GMS1 version requires my free buffer_zlib extension.
Creates a new Zip archive structure. Compression level can be 1..9 (from faster to better compression ratio), 0 (to skip compression), or -1 (to let runtime pick).
GMS2 version assumes all non-zero compression levels to be -1 because buffer_compress doesn't have an argument for compression level (you can also import the GMS1 version and buffer_zlib though).
Destroys a previously created Zip archive structure. Don't forget!
- zip_add_file(zip, path, file_path)
Adds a copy of the given file to a to a Zip structure.
For nesting, include slashes in path (e.g. "dir/test.txt").
- zip_add_buffer(zip, path, buffer)
Adds a copy of the given buffer to a Zip structure.
Path handling is the same as with zip_add_file.
- zip_add_buffer_ext(zip, path, buffer, pos, length)
Same as zip_add_buffer but allows to only add a section of a buffer.
- zip_save(zip, path)
Finalizes the Zip structure (meaning that no new files can be written to it) and saves the archive to the given path.
Finalizes the Zip structure and returns it's internal buffer.
Current size will be indicated by the buffer's writing position (buffer_tell).
Note that the buffer will be destroyed by zip_destroy.
