I have been fiddling with the wss scirra server a good bit in the last two days, so I have been the host for a number of people joining. I am trying to dissect the message structure that it uses to send messages back and forth in order to build a server capable of handling C2 multiplayer requests.

Here is what I have so far:

2 / 16728 requests | 0?B / 3.3?MB transferred | Finish: 2.3?hrs | DOMContentLoaded: 135?ms | Load: 134?ms

This is with my client as the host of the chat room.

Has anyone ever written any kind of guide on the API for the multiplayer in C2?

Not exactly helpful there.

Yea, but I don't want to do all of your work for you, as that would take me away from the copious amount of work that I have to do.

Like newt says, you have tiles, each with an id and some kind of schema for determining "open" vs "walled" edges, then you just roll a bunch of random numbers to determine id and position and do if-then checks to ensure that "open" matches up with "open".

You can use Rex's "Board" & "SquareTx" plugins to do the isometric part; he just uses an x,y grid and ports it into isometric.

Lots of random number generators and if-then-else statements.

I suspect they had a security bug that allowed for malware via images.

Just use http://postimage.org/ and [ img ] http:/ /postimage.org/123594082/image.jpg [ / img ] to include it in your post.

You cannot.

I use two separate sprites.

One is called "Button" and one is called "ButtonHover", then I just lay them on top of each other and set opacity from 100 to 0 and visa versa.

Gotta love the OpenSSL Heartbleed.

It is used in forming https tunnels that secure your connection between each user and your server.

There should be somewhere in Google Play that allows you to address dependencies or injected libraries. You just have to find the openSSL one and point it to the latest library on the web.

I am not as familiar with Google Play, so I cannot tell you exactly how to do this, but here are some relevant pages from Google:

If you want to setup a server, you can use Amazon Web Services. They have a server set that you can get for free for one year (even the non-free version for a t2.micro server is only 9.72 USD / month).

http://docs.aws.amazon.com/AWSEC2/lates ... n-ec2.html

http://docs.aws.amazon.com/AWSEC2/lates ... -LAMP.html

http://aws.amazon.com/ec2/pricing/#

You could setup a LAMP stack (Linux Apache MySQL and PHP) or you can use PostgreSQL, Oracle, or Cassandra instead of MySQL, and you can use Java servlets (running on Apache Tomcat) or Python in place of PHP.

Then you can use AJAX calls to retrieve data from the server.

We use AWS for our server sets, and we have been extremely happy with them thus far. Their billing people are a little overzealous, but you can work around that.

gumshoe2029 Erm my game will not be on the browser, it will be on the App Store. Will it be safe if its for the iOS Devices?

No, even there it is not safe. Apple has "Web Inspector Tools" for their Safari browser, which will give you all of the same powers as any other browser developer tools.

https://developer.apple.com/safari/tools/

As far as getting info, for instance, I will have a boolean that checks whether a layer is visible, then just print "true" or "false" next to the "Layer X is visible: " line in my debug text box.

I don't know of any better way to debug multiple sheets though, sorry.

Basically this is what I did. The "TotalBones" "Goldcoins" and "ShieldSinglePlayer" are some of the currencies in the game, am I doing it right?

P/S: I don't know any programming language and I'm still new to construct 2, been only using it for about a month and a half now. Pardon me for begging your help

You do know that hashes are one-way, right? You cannot retrieve the original data from those hashes without using a GPU-enabled computer to crack the hashes.

But regardless, the user can simply pull the variable out before you hash it.

There is no way to protect things on the browser.

gumshoe2029 thats a good idea, but my question is, is there a way I can do that in construct 2?

No, sadly. Nothing on the browser is ever safe. Anyone using Chrome Developer Tools or Firebug-like tools will be able to tweak any of your JavaScript source/variables at will. You have to store data on a server to be truly secure.

[quote:1uzwip9o]As far as actual data protection, anything on the server is safe.

No data on a PC connected to the internet is safe per se.

Well, yes, but for most people, they are adequately low priority targets to call the server "safe". You can use proxying, firewalls, and intrusion detection systems to deter attackers also. All of our game servers are not connected to the internet directly; they go through a firewalled/IPS gateway server first who proxies all requests back.
