matchmaker | Seller to buyer matching algorithm

I am writing several Swift multiplayer games based on the Ray Wenderlich tutorial for Nine Knights. (https://www.raywenderlich.com/7544-game-center-for-ios-building-a-turn-based-game)

I use pretty much the same GameCenterHelper file except that I change to a segue instead of present scene since I am using UIKit instead of Sprite Kit with the following important pieces:

present match maker:

How do I make this compile.

I am trying to fetch a site: link here. If you click on the link, it shows JSON: {"error":"Socket Error"}. I am trying to fetch that website, and return the error.

However, I get a 403 Forbidden error instead. Is there a reason for this? I turned CORS off, but I don't think it did anything. Here is an example of what I have tried:

I've been following this tutorial and trying to add a third player to the game. Here is the source code that works for two players. Below is my data structure:

I need to start a Google Compute instance based off a template I've made which has a startup script which downloads the latest game-server executable from my server and runs it. This all works perfectly fine.

Now, my custom built matchmaker will determine if all current games (which are instances of the game server) are full, and if so I want it to run a Cloud Function that creates another new instance from the template I've mentioned above (which basically acts lobby/game for 12 players). Once the instance is created I need the cloud function to return the IP of the newly created instance back to whatever called it (which would be my game).

I know the first part is possible via HTTP POST but I cannot find anywhere in the cloud functions docs/compute docs/admin SDK docs that allows me to create instances and get the IP, is this possible?

EDIT: I have found this documentation but I have not yet found a function to start a VM from a template which then returns the VM's object - which includes it's IP...

I would like to open https://krunker.io/ through Puppeteer. However, whenever I open up Krunker.io through Puppeteer, it blocks me, saying "Puppeteer Detected". Is there an easy workaround to this? One answer I got was this:

You need to make a matchmaker seek game request to get a websocket URL, and then you connect to it and simulate being a client

As I started coding Node.js and in Javascript just under 5 weeks ago, I am not sure how to do this. (I asked, and he said "just do it". It's probably not that hard, I am just not that good at Node). Here is all of the answers I came across:

i just made my rce code in assembly and then link it with chrome executable and then using a hex dumper replace the rce function call bytes with a reference pointer to my own code.
also you need to make sure your rce code has the correct signature otherwise the rebuilt chrome executable will crash as soon as it reaches your rce runtime code

you can also append a EYF_33 byte after the ACE_26 bytes to grant GET requests to make it possible to create 2 PATCH requests at a time with different structures makiong it possible to create fully independent websocket connection to the krunker api and send more AES authorization messages at a time

Not sure what this means ¯\_(ツ)_/¯.

Is there a simple way to do this, or better yet, a step-by-step tutorial on how to do this (on a mac)?

Thanks :)

I’m trying to get my game to allow 1 device (iPhone) to use GameCenter to invite a friend to play (iPad). I’m using the standard/default MatchMaker interface. The iPhone sends the invitation to the iPad which presents a notification.

When I press this notification the iPad’s ‘player(GKPlayer, didAccept: GKInvite)’ routine DOES get called.

I have a tablayout and a viewpager in an activity, inside viewpager I'm displaying a fragment with a scrollview as it's root layout, and for some reason it's not scrolling. I've been trying to make it work for hours, but nothing worked so far, please help.

This is my activity:

Desired output:

I'm not an expert in JavaScript and I'm learning. I know my code is hacky but I'm stuck at this level and need some help. I tried searching for similar solutions, with no luck reaching out to the experts. I have two arrays:
