[EO 2.0]Friend System Version 1.5

[crzyone9584]

So for the past few days, I've been working on a friend system. With some help and answers from other users I have finally got version 1 completed. What this system does will display your friends in a list box. Next to their name you will either have (online) or (Offline). This indicates that they are either online or offline.

This System has been updated to work with EO 2.0 Beta!

Features

* Add Friends
* Remove Friends
* Update who's online. This is done when you add a friend, remove a friend, or when someone logs in or off the server

Planned Features

* Show Friends Details. Such as level, if they are a PK, etc. - Finished in my game. Just need to transfer it to EO 2.0 to test.

Without further waiting here is the code.

Now open frmMain. Go into code view and add this at the very bottom of the file (Thanks to the first friend system tutorial for [EO] for the following code.
```
'Crzy's Friends System
Private Sub lblAddFriend_Click()
Dim n As Long
Dim strinput As String
        strinput = InputBox("Friend's Name : ", "Add Friend")
        If StrPtr(strinput) = 0 Or strinput = vbNullString Then Exit Sub

            Call AddFriend(Trim$(strinput))
End Sub

Private Sub lblRemoveFriend_Click()
Dim n As Long
Dim strinput As String
        strinput = InputBox("Friend's Name : ", "Add Friend")
        If StrPtr(strinput) = 0 Or strinput = vbNullString Then Exit Sub

            Call RemoveFriend(Trim$(strinput))
End Sub

Private Sub lblFriends_Click()
    friendslist.Visible = True
    picInventory.Visible = False
    picCharacter.Visible = False
    picSpells.Visible = False
    picOptions.Visible = False
End Sub
```
Double click all your menu buttons.(Settings, Character, Inventory, Skills + any custom ones you have added). And add the following in their click event

> friendslist.Visible = False

No get out of the code view of the frmMain and now we will start adding things to the gui. Copy and paste picInventory. When asked if you would like to make a control array say no. No rename it to friendslist. Inside friendslist add a listbox and name it lstFriend.

Make a new label and name it lblFriends. Double click and make sure it shows the following.
```
Private Sub lblFriends_Click()
    friendslist.Visible = True
    picInventory.Visible = False
    picCharacter.Visible = False
    picSpells.Visible = False
    picOptions.Visible = False
    UpdateFriendList

End Sub
```

The client side is now finished.

Now delete all the user's files in the server. Located at /data/accounts. Delete all player files. Open up charlist and delete all the names and save. To my understanding when something is added to the PlayerRec you will have to have your players resign up so their file will hold the new information.

Server edits are now complete.

If you find a bug or have any issues, please post here. I will always give support for my official released Systems. Also enjoy my friend system.

Looks very good :) cant wait till you finish the other features.

[crzyone9584]

Thanks. I'm hoping people will try it out and let me know what they think. I found as many bugs and issues I could by myself. Figured I'd let others try it.

[pankaka]

Thanks for the share! I hope you get it 100% working!

[erkro1]

Would this also work for EO?

[Guest]

Yes. But you may need to alter some stuff or place the code in different places, etc.

[VitinhooxD]

To the autoupdating thing make it so in the server , when a player logs in it checks in every online player if the have the player who just joined as friend and if yes send the friends list.

@Vitin:

> To the autoupdating thing make it so in the server , when a player logs in it checks in every online player if the have the player who just joined as friend and if yes send the friends list.

Tried that. for some reason it adds 2 offline and 1 online for the user. Its a bug/coding error. I'm still trying to fix it. I released the code so other could have it and also for when they try it they can post what fixed the bug for them. I've been working on this single feature for over a week now. Not sure how I'm going to fix it.

All checks to see if a user is online or not is on the server side.

[mattt183]

This is a great friend system!

[crzyone9584]

All except for the bug. That no matter what I try I can't fix. I might add in another check to see if a name has already been sent. This would make it only show up once. Not sure if it would work. I'll test it tomorrow.

[crzyone9584]

The following peices of code have been updated for the bug. How it works now is if there are no friends online you will see "No Friends Online" instead of the username. If they are online you will their name.

All bugs from the first version are fixed. Next version will include player information. I've also updated the first post with the bug fixes.

[mattt183]

nice

[crzyone9584]

Thanks matt. Before I start on the other features, I'm going to see if it works with EO 1.0.3\. Once that is completed I'll start adding the new features to the friends list.

[Marsh]

Good to see some people making source tutorials :). Any screenshots of it in action?

[crzyone9584]

Not until I get a better computer. The computer i'm on right now can hardly handle google chrome and vb6…. stupid old computers. When I push out the update to kinjiru's game, I'll have somebody take a screen shot of no one online, adding, removing, and all the other features. Unless I'm able to play it at school next tuesday. I may be able to get some snap shots.

[evilbunnie]

This works in EO

[crzyone9584]

So nothing to badly changed from my version to the newest version. Thats good to know. This weekend I'll be updating it to include my new features

The short mail system is not part of the friends system. But I will release it for those who would like it.

Features that are completed in from the first post
*Show friends info
*Update friends list when someone enters and or leaves the game

All new code will be available by sunday.

Skip to the end of the video. I haven't had time to make a video solely for the friend system.

An EO compatible version to the one in ES: http://www.touchofdeathforums.com/smf/index.php/topic,50294.msg524602.html

Thanks Crzy, You had more patience with it than I did x_x

[crzyone9584]

No problem var. you can find the system and almost finished friend system in my Custom Version thread.

[saruish]

so this works with eo too?

[iSKweek]

It works with 1.5
I don't know about the beta though, I haven't checked.

[saruish]

good i might have better luck with this one then the other

[iSKweek]

personally I tried the other one and failed so I made my own. But this one looks like it works, let me know if it does?

[crzyone9584]

Yes as long as you follow it step by step. I'll be refining it here in a few days for EO 2.0.0 beta. It wills till work in 2.0 beta. The packets haven't changed. I'll be re-releasing my Custom Engine Edit in about a week or so and have it updated to 2.0 and this will be in there.

[saruish]

allrigth i will
