How to get Multiplayer / Coop Working - In Depth Guide

[ttv.Linkypoo]

I just updated this to also include Hamachi instructions down at the bottom.

I only got this game for multiplayer. I struggled for a little to get it working. People who want to get multiplayer working should read this to save yourself trouble. You must follow this entire thing to get it working - it's super simple-ish. I will help you <3.


1. Multiplayer Overview

The devs have stated multiplayer is definitely in alpha state. The only game breaking thing I have found is that when you teleport to other islands your frames will drop to 10-15 FPS. Super easy to fix, run to an open area, save your game, and restart your game completely (that means close it silly). I say run to an open area before quitting because the first time I did this I ended up below the entire world. Thankfully you can swim out from the terrain and play normally again.

2. cracks fingers To get multiplayer working follow me - ONLY THE HOST NEEDS TO DO THIS!

You need to port forward. I figured all of this out in like 30 minutes but I had some general knowledge of how to do it before and I'm stubborn as hell (thanks mom!)

I know people don't read on the internet so I will say this again - ONLY THE HOST NEEDS TO DO THIS!

1. Run command prompt (windows search "cmd", run Command Prompt)

2. Type "ipconfig", hit enter

3. Scroll down till you see the "IPv4 Address" and copy those numbers down (example: 192.168.1.47) - DONT CLOSE THIS WINDOW YET!

4. This is your computers IP address and we will use this later, keep this window open and...

5. Look for the entry "Default Gateway ........ ##############"

6. You should see a bunch of letters numbers. What is important is the numbers that look like this "192.168.1.1"

7. This is your router's IP address

Take a deep breath... exhale... and let's continue...

8. Open up your internet browser

9. Type your router's IP address in the URL bar (mine is 192.168.1.1), hit enter

10. You will get a warning that says "THIS SITE IS NOT SAFE" ooooOoOOo spooky, not really, click the "more options" at the bottom of that warning and then click "Continue" or "Proceed"

11. Typical username/password for a router is something like admin/admin or admin/password

12. Once you log in, this is where you'll need to click around the menus to find what you are looking for. All routers are different.

13. You may also need to set the control panel to "Advanced" so you can see "Router Settings" or "Access Control" -- for me, my "Port Forwarding" was under " Access Control"

14. Add a new rule under "Port Forwarding" that is like so:

Give it some name "OMG IM DOING IT MOM - Craftopia"
External Host: leave this blank
Internal host: this your IPv4 address from #3
Protocol: TCP
External Port: 8787-8790
Internal Port: 8787-8790

anddddd one more time we're going to celebrate unc unc unc

15. We add another rule...

Give it some name "Again? ugh...Craftopia"

External Host: leave this blank
Internal host: this your IPv4 address from #3
THIS ONES DIFFERENT >>> Protocol: UDP <<<
External Port: 8787-8790
Internal Port: 8787-8790

16. Save / Apply / Whatever

Ladies and gentlemen, boys and girls, we did it - I mean I did it, you just copied me. Jerk. Your nerd friends can now join you and you can all nerd out together!... nerd

Hoped this helped.

Edit

You can also use hamachi which is much simpler (but you all need to download it).

1. Everyone installs hamachi
2. Create accounts
3. One person create a hamachi room
4. Give hamachi room info to friends\
5. Everyone connects to the Hamachi room
6. Host game in Craftopia
7. Invite friends

I'm just gonna comment here to bump this post up for those struggling with multiplayer.

You clearly went pretty in-depth here and took a bit of time to write all this up, so it should the recognition it deserves.Very concise and in a step by step format - good job. Keep doing what you're doing.

I also noticed you put this in the guides section too, expect a +1 on the thumbs up in a moment.

Thank you! :)

Just to addon with different router models, if you come across NAT 1-2 (Network address translation) just "enable" it if you wanna to communicate from host-client IP.
Some router tend to close it by default and some work along when you portforward your router.

so is this the only way to play with friends???

and does the steam in game multiplayer not work?

Yes. Having a moderate skill level of networking or server setups are currently the only way to really get multiplayer working. Craftopia hasn't officially setup a direct Steam connection to their multiplayer portion of the game so aside from the rare exception trying to "join" someone through Steam will not work.

There are workarounds for this using things like Hamachi though if you're not familiar with messing around with the backend settings of your router. Personally I find Hamachi to be very irritating to COMPLETELY remove from my computer though, so unless you're desperate steer clear of that.

Edit: If you are not familiar with how to work your router's backend settings there are guides out there in regards to it if you know the exact make and model number of your router. It's a very fiddly thing at first, but once you understand it - it's actually quite easy and can be done within a minute or two. Portforwarding can also actually substantially help with latency/ping in various cases aswell. Also an incredibly useful skill to have when wanting to setup your own servers for other games on your PC.

We had the same problem and after i opened the ports
- 8787 tcp
- 8787 udp
- 8790 tcp
- 8790 udp
everyone was able to join my game.

Good to know that there are more things to do if we struggle again.

I believe it was your reply in on the 2nd page of searching "multiplayer" that helped me get it working.

Thanks bud!

3. Scroll down till you see the "IPv4 Address" and copy those numbers down (example: 192.168.1.47) - DONT CLOSE THIS WINDOW YET!

Should be noted that this is your LAN IP address. You will want to find your public IPv4 address from a site like Whats my IP[www.whatismyip.com]. If someone outside your home network tries to connect to the IP address you find from "ipconfig" it will just fail every time.

[D's Journal]

Hard pass.

[Miku]

I've tried this but my when I Host&Play, the went into an infinite loading screen, any Idea how to fix?

[Dreamer Zetsuna the Sleepy]

Respect
i am not going to do it atm. But bumping you

[Tinydancer]

Bump cuz it worked

It's been working for all of us and we aren't in the same home network, let alone the same state haha. I am using my LAN IP address as you stated.

Me and My buddy have tried this every which way and still cant get multiplayer to work, usually he gets stuck loading assets as do i. I Hope someone has any ideas what to do.

Unfortunately none of us would be able to narrow down specifics since each and every router is different. I can say that this does need to be followed to the T and in the right fields though otherwise it will indeed fail. Not only that, routers can be so exceptionally different that sometimes both parties may need to port forward (at least that is the case with my uptight router).

Google how to port forward your specific router make and model to ensure that the fields you and your friend had entered with all of the above is correct. Also be sure to check the comments for they may hold something vital in order to help you and your buddy get it working.

Hopefully that helps somewhat, good luck matey.
