During this time, there is no time to write 3D programs because you want to use ACE, work on work. I found that ACE is very easy to use, you can simply implement all network programs. Write services, write clients are quite convenient.
At present, ICE is being tested simultaneously to connect many users, realizing multi-user connections, just like BT.
Next time, if you want to add a network part to a 3D game, you will definitely choose ACE.
