The modules/raycast/godot_update_embree.py script can be used to pull the relevant files from the latest Embree release and apply some automatic changes.

Some changes have been made in order to remove exceptions and fix minor build errors. They are marked with // -- GODOT start -- and // -- GODOT end -- comments. Apply the patches in the patches/ folder when syncing on newer upstream commits.

enet

• Upstream: http://enet.bespin.org
• Version: git (ea4607a90dbfbcf4da2669ea998585253d8e70b1, 2023)

Three files (godot.cpp, enet/godot.h, enet/godot_ext.h) have been added to provide enet socket implementation using Godot classes.

It is still possible to build against a system wide ENet but doing so will limit its functionality to IPv4 only.
