Files extracted from upstream source:
|
||||
|
||||
- all .c files in the main directory
|
||||
- the include/enet/ folder as enet/
|
||||
- all .c files in the main directory (except unix.c win32.c)
|
||||
- the include/enet/ folder as enet/ (except unix.h win32.h)
|
||||
- LICENSE file
|
||||
|
||||
Important: Some files have been modified by Godot developers so that they work
|
||||
for all platforms (especially UWP). Check the diff with the 1.3.13 tarball
|
||||
before the next update.
|
||||
Important: enet.h, host.c, protocol.c have been slightly modified
|
||||
to be usable by godot socket implementation and allow IPv6.
|
||||
Two files (godot.cpp and enet/godot.h) has been added to provide
|
||||
enet socket implementation using Godot classes.
|
||||
Check the diff of enet.h, protocol.c, and host.c with the 1.3.13
|
||||
tarball before the next update.
