MMO Starter Kit

Careful with the launcher. I dont know if you fixed this issue but in your original test download, the launcher had unsecured FTP information in one of the files. Simply opening the file in text editor exposed everything needed to log into your FTP account.

This was a very early version of the launcher so it may be fixed by now. If not, why does the launcher need ftp info anyways? It should just be able to download the files off the server. I dont see a practical purpose in allowing the launcher to upload files.

@FlyofAvalon: I use a read FTP account and my username and password is encrypted. I agree that the launcher doesn't need write access to the server.

[Zydronium]

Why use FTP anyway? Why not HTTP?

I don't have FTP :P (I use SSH to upload)

[KRushin]

First, Thanks for making this toolkit!

I've got a problem when I want to login and register;
I get the message that I've registered and logged in, but he next screen won't load...

I use version 4.6 of unreal engine.

For those who may be having problems getting to character list / be able to create a new character and have it go back to character list. Make sure MySQL stuff is correct (should say Logged In!) But if still not transitioning correctly please read below.

In current version there are couples problems that can be fixed one of two ways:

Easy way:
Change your PHP settings to turn off display errors
Reason: For some reason if php encounters an error, it will break, and not send any json data
http://php.net/manual/en/errorfunc.configuration.php

Fixing 3 small bugs

• Fix the problem problem that rosella brought up at the bottom of the post with declaring multiple json headers.
  Remove them from the bottom of the bottom of each file.

  $chars = $conn->query($sql);

• In mmocreatecharacters.php
  Note: until gender is implemented in character creation we will hardcode it to 0
  
  

  $gender = $mydata ->gender; 

  to
  

  $gender = 0; 

After that, hopefully it won't depend on how your php is set up.

Hi, I've purchase this on Sellfy, but I can't find the Sword girl asset and the Character Mesh Switching Example for Blueprint.
This means :
The demo is no sword girl asset.
I don't see the example BP for changing player's mesh.
Best regards.

@KRushin: I have disabled the errors (display_errors), which I don't realy like, but now I get the character listing.

When I want to enter the world (I've set the character id to 0)

I get an error with the following stacktrace:

you don't have to disable errors if you make the fixes i listed in the previous post (how i'm running it).


Are you trying to play in the main world/level you want to play (desert rally)?
Check the FAQ, if you have done any changed spartan addressed some problems with that error

[Zydronium]

Ok I'll check that out

Well I did a quick "fix". First I want to see it working and then building it out.
Besides I want to swap out PHP and replace is with C# ASP.NET, like my other systems.

I have some PHP sites running though, but prefer .NET

[CodeSpartan]

Hi Zydronium, and thanks for purchasing

First of all, if you register and can create/choose a character successfully, the issue is almost certainly not php. Are you trying to enter the world from editor? That's not possible, you can only check that transition from standalone/packaged (Listen Server part of the documentation). If you get this error when running standalone, check these two things:
1) the client's shortcut has -local parameter in it (otherwise it will try to connect to the server ip specified in mmologin.php)
2) the project settings have valid map specified as server default map, and this map has a JSONRequests object in it

In current version there are couples problems that can be fixed one of two ways:

Thanks for finding those!

Guys, note that you only have to apply this fix if you have problems with getting php to work. Also, either turn off display errors in the php settings or fix the lines KRushin posted, you don't have to do both.

Hi, I've purchase this on Sellfy, but I can't find the Sword girl asset and the Character Mesh Switching Example for Blueprint.

Hm, doesn't the documentation say you have to duplicate GuyPlayerCharacter blueprint? Please use the latest documentation linked in the first post, section "Customizing the player character".

the launcher had unsecured FTP information in one of the files.

This account is supposed to be public, read-only, and this is mentioned in the documentation. Actually, I would recommend using anonymous account for that.

Hi, Sorry for my post is not clear enough.
What I mean is that there is no career/role selection demo in your project.
Which means select different career will spawn different mesh.
In your demo, you only assign default pawn class.
What I mean is spawning actor with different pawn class dynamically.

Best regards.

I plan to add differences between classes in one of the future updates. However, the demo is based on WoW and in WoW the character mesh is the same for each career, only the armor meshes are different. Still, it's very easy to do this the way you want (with different meshes): in JSONRequests blueprint, in OnGetCharacterResponse function before the server assigns the character's stats, you can destroy the player's character (Destroy Actor), spawn a new one based on the career (Spawn Actor From Class), and make the player's controller Possess that newly spawned character.

[Jkthrp]

CodeSpartan, if I buy this kit on Sellfy, will I have future updates?

[CodeSpartan]

Yes, Sellfy purchasers can download the updated kit automatically after the update comes out.

[Agentleo]

Bought . Price alone is just worth taking a look under hood of network programming. Over the next few days I plan to play around with it and setup a backend with Laravel.

[ProfessionsQuest]

Hey CodeSpartan,

Love your work! We are using the Launcher System for our game, and it works great. We have found a weird issue that hopefully you might have some insight on. When we build out the launcher, and set up the files, it works great. Connects, downloads, and all that.

But, when we package up the launcher in an install file using Inno, the launcher will start, but will get stuck on deleting temp files and never download. Are there any ideas from you on what could be causing this?

EDIT: I figured it out. Nothing wrong with your side. When you install with it, you have to Run it as Administrator.
