Portable Minecraft v1.40

[o0Julia0o]

hey - will the MCLauncher be updated to the actual minecraft-version?

[Koolio]

Well its been a while since I looked at the project at least 2years.. And I am aware that parts of it no longer work like it used to due to Mojang changing some of the way they do  account authentication. It does seem to launch and download newer minecraft versions fine-atleast last time I tried, and so long as authentication is off it seems to run them... but adding custom mods is broken as it seems newer mods now need to pull in extra library files aswel..and this launcher was never updated to support that.

Anyway  I haven't really followed minecraft updates in a long time so I'm not sure if those changes were big or small.. and the time to find out and fix that might not be worth it or even possible.

Still it's annoying as I did prefer my own launcher way more than mojangs, but I really don't think there would be much point in updating it now.. its not known or used by many people, and I have other projects to be getting on with.

So to answer your question probably not sadly, it is I guess abandonware now.... done as hobby project at time when I played the game and needed a launcher that just worked better.

Hi Koolio, how can i get forge running with MCLauncher? I tried to put assets and libraries in the folders of MCLauncher and the forge-folder in the versions-folder of MC-Launcher but it doesn´t work.
Here is a pack with libraries, assets and Forge-folder(with forge.jar): http://www89.zippyshare.com/v/QbhuNLcr/file.html

Can't get it working without fixing the bugs in the launcher, the issue seems to be in in the newer 1.11 releases mojang changed some layout in the json data, it fails to see which library files to download or load up on startup..


Official launcher for particular bunch of liteloader/forge mods...

So pretty big difference on the number of jar files it is missing on the launch command for my own launcher.

Like I said before though my mclauncher is pretty much abondonware right now. So only older mc releases will launch properly... also even if I fixed this issue of it not reading the newer json files and got it launching mc.. it still has the problem of not authenticating a legit account with mojang servers to get a valid access token and that might just impossible to fix now.

[o0Julia0o]

thank you Koolio for looking into it!!! Yeah - premium-loings would be another problem. The non-premium login is working up to the actual minecraft-version 1.12.2!! But i hoped you could get forge to work with the MCLauncher - or tell a workaround, what to do with the forged files/folders from other launchers - so the MCLauncher can start them.

[Koolio]

I looked into yesterday.. premium logins with mojang servers are working still, it seems to get a accesstoken fine first time.. but on subsequent tries it gets a 403 forbidden.. I'm thinking this is mojang not accepting multi logins after a short period of time, where official launcher uses some stored session file.. which I don't support in my launcher, might have to fix it properly though.

also found out what was wrong with it not loading up most the jar files compared to the official launcher.. the code wasn't understanding inheritsFrom

in the json file for forge/litemod version like 1.11.2-LiteLoader1.11.2-1.11.2-forge1.11.2-13.20.0.2226.json you will have this line:
"inheritsFrom":"1.11.2-forge1.11.2-13.20.0.2226",

which means it needs to load the file "1.11.2-forge1.11.2-13.20.0.2226.json"  from the other version folder.. this part was working, however in that file it would have a line like "inheritsFrom":"1.11.2",... which is the base original version of minecraft these this modded versions would be using.. and my launcher didn't ever get past loading the library files from the original.. I guess that level of recursion wasn't expected, still I fixed that .. so now my launcher includes all the same jar files in the commandline as the officiallauncher.. I figure that would get it working, but now its a got different error..

its meant to put the base jar file to load up in the startup as .minecraft\versions\1.11.2\1.11.2.jar ..as it is the last inheritedFrom file... instead it was trying to load this...

\.minecraft\versions\1.11.2-LiteLoader1.11.2-1.11.2-forge1.11.2-13.20.0.2226\1.11.2-LiteLoader1.11.2-1.11.2-forge1.11.2-13.20.0.2226.jar

which doesn't exist.. still even after fixing that problem, its now got a totally different error

"---------------------------
Launch Error
---------------------------
Exception in thread "main"
---------------------------
OK   
---------------------------
"

and I'm at loss as to what the problem is with it now, as the command line args from my launcher and official are pretty similar now... at least another 30 more jar files more than how it was before.. when it was only loading up the jar files from the 1st/2nd version folders...

Notice the uuid and accessToken from premium logins are included so it does work

Anyway it will have to wait as I could debugging that for hours and I don't have the time, might look at it next week though, i guess some progress has been made on it either way Just a few more fixes away from getting it working again I'm sure now, though looking at the codebase again it really is a mess.. and now I remember why it had abandoned it

^^. Uh - wow, o.k. Thank you for deeply looking into it, Koolio!! I think i can´t really help - hm. For me it would be nice, if i could use a forged jar(json, libraries, assets) from another launcher. So it´s portable, in the end with the MCLauncher. I tried all the way told, but - yeah.. the problem seems to be huger.

I would be happy, if you could say more in the next weeks.

Copying this 3 folders into the KZ-Launcher-Folder - and the KZ-Launcher can handle newer versions:

assets
libraries
versions

This is working with Minecraft 1.12.2

I tried the same with Minecraft 1.15.2 and getting this error after trying to launch 1.15.2 out of the KZ-Launcher:


Any chance to get 1.15.2 to work with the KZ-Launcher? THX!

This is a bit out of my knowledge zone; however.. did you copy those 3 folders from a java version on you computer correct? And it works with 1.12.2, but not 1.15.2?

Are you coping 1.15.2 folders in the same fashion from an external version, or are you updating them through the launcher?
If so it would seem there are file conflicts, and i've had this kind of same issue years ago when i tried installing tons of mods to my single player worlds haha.

I don't really know German but the error is saying something along the lines of "The object is not set to an instance"

Ill try and replicate the same error to see if I cant help out, meanwhile, try to completely reinstall the launcher; like delete all the files and try it from scratch, going straight to 1.15.2

yeah it used to be possible to use the old mc launcher if you had the official mc launcher to initially create and fetch all the files for things....

alot has changed in the recent mc versions and the launcher just doens't understand some of the  json files now, including login detail connection handling...

honestly its just not worth using my launcher for newer mc versions now as it won't work with plugins like Forge either, as they seem to want to download something new each time, so even doing the copy folder tricks won't work to get even the offline mode to startup.

But nice to know someone was still using the launcher for older version.. I still prefere it myself as it was faster and quick to run, but the work involved in making an updated one just isn't worth it for me now so sorry I can't help with that.
