You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Keep it simple and clear!
I want to achieve a 1v1 type multiplayer matchmaking with disconnection protection that ends when one player loses all of their lives.
What is the issue? Include enough details if possible!
No idea how would I implement it.
What solutions have you thought of so far?
I thought of a service where it would create a separate folder/instance for both players but have no idea on how to implement it.
After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!
