« on: March 12, 2022, 09:01:39 pm »

The game uses SFML for the graphics so hoping this post is alright  The game is developed in VB.NET.

A new update will be released on 2022-03-18 that introduces Battle Royale amongst a lot of other things to the 2D MMORPG Key To Heaven. You can follow the countdown on the website: https://www.key2heaven.com/

There is also a 50% exp increase for new players when the update hits!




In K2H, your goal is to fight and explore on the mysterious islands. Become stronger, equip better items, craft a raft and sail parts of the oceans to find more hidden treasure, secrets, and bosses.

The game can be downloaded on Steam: https://store.steampowered.com/app/1347630/Key_To_Heaven/

Key To Heaven is a 2D MMORPG. I posted this project some months ago but want to share it again cause it has received a lot of love sence then This year it has received new graphics and is now a month or two away from the Steam release.

I have now made a Introduction/Origin Trailer for the game:

Graphics / Re: Failed to load texture from memory

« on: January 25, 2020, 10:51:12 pm »

It seems integrated hd 3000 do not support images larger than 4096x4096px. And I'm pretty sure that is the issue.

Graphics / Failed to load texture from memory

« on: January 25, 2020, 12:04:18 am »

I'm using sfmlnet-graphics-2 version 2.2.0.0.

A player of my game is running with specs:

i3 2350m with intel hd 3000 integrated 6gb ram

He is successfull in loading the first image file that is 7mb but fails on all others (ranging from 1mb to 26mb). He gets the following error:

 SFML.LoadingFailedException: Failed to load texture from memory
   at SFML.Graphics.Texture..ctor(Image image, IntRect area)
   at SFML.Graphics.Texture..ctor(Image image)
   at K2HGame.SFML_Utils.TextureFromDecryptedFile(Byte[] buffer)
   at K2HGame.modDirectX.InitSurfaces()

And the code for TextureFromDecryptedFile is:

    Public Shared Function TextureFromDecryptedFile(buffer As Byte()) As Graphics.Texture
        Dim image As Graphics.Image
        image = New Graphics.Image(New IO.MemoryStream(buffer))
        image.CreateMaskFromColor(New Graphics.Color(0, 0, 0)) 'Setting alpha to 0 for all pixels with 0,0,0 rgb
        Return New Graphics.Texture(image)
    End Function

So what I'm looking for is what could be the cause of this issue. Could it be my coding that is bad? I do encrypt all graphics files, and use this to decrypt them:

(click to show/hide)

Public Shared Function DecryptFile(strInputFile As String, bytKey() As Byte, bytIV() As Byte) As Byte()
        Dim inputFile As System.IO.FileStream = Nothing
        Try
            Dim result() As Byte = {}
            inputFile = New System.IO.FileStream(strInputFile, FileMode.Open, FileAccess.Read)

            Dim cryptType As New System.Security.Cryptography.RijndaelManaged

            Using ms = inputFile
                Using cs As New CryptoStream(ms, cryptType.CreateDecryptor(bytKey, bytIV), CryptoStreamMode.Read)
                    Using ms2 As New MemoryStream()
                        cs.CopyTo(ms2)
                        result = ms2.ToArray()
                    End Using
                End Using
            End Using

            inputFile.Close()

            Return result
        Catch ex As Exception
            MainHandler.LogException($"DecryptFile {strInputFile}", ex)
            inputFile?.Close()
        End Try

        Return Nothing
    End Function

So what I do is basically decrypt the image file and then load it into the texture:

m_Paperdoll = SFML_Utils.TextureFromDecryptedFile(DecryptGfx.DecryptFile(filename & "paperoll.encrypt", bytKey, bytIV))

Any and all ideas are appreciated.

Thanks, yeah it was started in VB6 so that should say something xD But last year I ported it to .net and thats when I also decided to go for SFML and so far I really like it.

Now I just need to build a community so that there will be a player base for it when I release it on Steam.

I'm an indie game developer from Sweden and way back in 2005 I started a 2d mmorpg. Although I have taken many breaks during this time, it is now very close to finished. All the graphics ni the game is handled with SFML <3 The game is programmed in VB.NET. Beta testing is now OPEN and you can download it in the discord channel. So if you want to provide suggestions and features you like, now is your chance to get them implemented. Or you can just join if you want to try an old school type game before it gets on Steam.

Discord: https://discord.gg/TmHHJkG

You can view the trailer video here:

Main Features:
* PvP, PvE.
* Crafting, Smithing, Upgrading/dye items.
* Questing, Lore, Survival.
* Optional Hardcore mode.
* No class requirements, make a unique character.
