Modloader

Makes it easier for other mods to be installed together with less conflicts. There are a lot of mods that depend on this, so it’s pretty much a must have!

Creators Description
A mod, kind of like a mod manager, that stops conflicts with mods that alter rendering, recipes, add entities, gui, smeltables or fuel. If you’re a modder, feel free to decompile this and learn how to make mods work with it. Inherit BaseMod and override any methods as necessary. The mod’s main class file should be prefixed with ‘mod_’. Read the Javadoc for information on methods available.

      • modman

        @EnderOverloard
        Hi, just check the error log you submitted, did you have Forge installed before you installed ModLoader? If so, then re-install Forge and it should work fine.
        If not, let me know.

    How do i fix it :(

    • modman

      @Darkvision32
      Hard to say without knowing what mods you have installed and the order they were installed.
      Might be quicker and easier to backup your worlds, delete the .minecraft folder, download & install fresh Minecraft 1.2.5, restore your worlds, install ModLoader, test, install other mods you want one at a time and test after each one.

  • Izual Zephyr

    Is it only possible to install this using 7-zip, or can this be done with other programs?

    I tried to do it with izarc, it wouldn’t let me do step 11. (the step above the first picture in the installing part)

    When I drop the files into the jar file, they won’t appear there and they’ll stay where they were, if I try to extract them to minecraft.jar, it says I don’t have sufficient permissions to write to this directory, I’m not an administrator so does that mean I have to be an administrator?

    I’m too scared to ask my dad to let me borrow his account.

    • modman

      @Izual Zephyr
      You should be able to use most archiving programs. I’m not familiar with izarc but just downloaded it and tested, but it wouldn’t let me copy the files straight over. PLus IZArc has lots of additional annoying software it wanted to install. If you can, download and use 7-Zip. Tell your Dad that an IT Professional of over 20 years (I’m not joking) advised that IZArc is NOT a good program to use for installing mods and that you need 7-Zip (it’s free and doesn’t have additional annoying software). I think the insuffucient permissions is due to the way the IZArc program is trying to move the files, but you won’t have that problem with 7-Zip.

      • Izual Zephyr

        I downloaded the latest version, and when I tried to install it, WAY too many files couldn’t be opened for writing. Did I download the wrong version? I am using a windows xp, and the file I downloaded is “7z920.exe”. There is different choices for 32 and 64 bit, and the file type could be exe or msi, so I don’t know which one might work.

        • modman

          @Izual Zephyr
          It sounds like you have permission problems on your computer. Am guessing your system is 32-bit, and either .exe or .msi should work. If you’ve downloaded an incorrect version, it would most likely tell you that it’s an incorrect version. It would really help if your Windows profile can be upgraded to have administrator priveledges while installing 7-Zip.

  • Izual Zephyr

    Plus, I’m using version 12w27a, which would translate into:
    year-2012
    week-27
    alpha
    Are mods even compatible with development versions?

    • modman

      @Izual Zephyr
      Can’t guarantee anything will work with development versions. Stick with the 1.2.5 release unless your keen for bugs and glitches.

      • Izual Zephyr

        11 days later, I tried it, installed modloader ONLY, deleted meta-inf, black screen. haha.

  • jbaker96

    The only mod i have downloaded is forge, but this is the only mod that i can find that triggers the error

    • modman

      @jbaker96
      Did you install Forge after ModLoader? If you don’t it will crash.

  • Izual Zephyr

    Okay, I got winrar and it worked, now I’ve got yet another problem…
    This one isn’t SO bad, like the one before, It’s the ordering of installation:
    modloader
    playerAPI
    clay soldiers
    too many items
    trading mod
    mice workers
    I’ve heard that when managing mods for minecraft, it ain’t like other games where you can just get the mod and put it in, you have to follow an order or your game system goes nuts. (and i just happen to be oblivious to what this little order is)

    • modman

      @Izual Zephyr
      yes, that order should work in theory.
      Is minecraft crashing after installing them?

      • modman

        @Izual Zephyr
        FYI – I’ve just installed them one at a time in the order you listed and tested after installing each one and MC worked fine and all mods worked in the game.

        • Izual Zephyr

          I did the same thing, and it had a black screen.
          Later found out I forgot about the meta-inf thingie, so I deleted it.
          Tried them in the same order and checked after every mod, it worked.
          =]

  • Izual Zephyr

    oh and, when dragging the files over, do I replace existing files, or skip them?
    There’s an option to “update” files, but I don’t know what that means.

    • modman

      @Izual Zephyr
      You need to replace existing files.

  • Orcrin12

    I need help. I tried to download this and it worked then i dragged it into me minecraft.jar folder. this is the only mod i had except TMI. i dragged it in and it seemed to work, my meta-inf folder should have been deleted since i didnt see it and i deleted it for TMI. I went into minecraft and it had destroyed my worlds! i had backed up my minecraft.jar like you said and restored it, no worlds! and it destroyed TMI with it! i really want modloader so what do i do? thanks!

    Orcrin12

    • modman

      @Orcrin12
      OK, this is the second report of this happening… Can you please advise what operating system your on and which archiving program you are using?

    I don’t know what to do. I just updated my minecraft and this is the first mod I’ve
    added. I followed the install to the letter, with the exception that I use WINRAR
    instead of 7-ZIP.
    Little help?

    • modman

      @Tholomew Plague
      I would try backing up your worlds then deleting the .minecraft folder in %appdata%, then download a fresh Minecraft 1.3.2, test it works properly, then install ModLoader for 1.3.2 again.

  • Tholomew Plague

    @modman
    Works now! Thank you

    I tried downloading the core mods you have listed under version 1.4. I did everything the Toolkit told me to. I even started with a fresh download of MC, I then downloaded Audio Mod, ModLoader, and Forge, and when I try to run MC, a box pops up that says a fatal error has occurred between MC and Forge.

      Hey bud, sorry we’re a bit behind updating the instructions at the moment. Concentrating on getting the Modgician application finished off and ready for public release.
      Am wondering if you deleted the META-INF from minecraft.jar?? In 1.4.x you don’t need to with Forge. Please let me know if that fixes the problem.

  • stevo501

    your 1.2.5 download link does not work i clicked it went on media fire and it said that the file has been removed! plz give me another link.

    • modman

      @stevo501
      Thanks for that. Yes, it looks like it has been removed from his mediafire account and there is no new link.

  • 2012

    can u please add a version for 1.2.5

    i need it for the portal gun mod.

    • modman

      @2012
      Unfortunately Risugami is not making available ModLoader for Minecraft 1.2.5 to 1.4.5 – his link always only goes to the latest version.
      However with Portal Gun, you can use Forge instead of ModLoader.

  • noob707

    This doesn’t work mine won’t even load up it says done but it not this is a lie it doesn’t work you need a better modloader

    • modman

      @noob707
      This is a common problem when it is not installed correctly.
      What version of Minecraft are you running?
      What other mods do you have installed?
