I'm getting a strange error on my mod. It works in eclipse but when I reobfuscate it, it has this error:

    It's on 1.5.1 by the way, It was working in 1.4.7 and 1.5 but now 1.5.1, and it's all updated

     

  • Quote

    1.5.1 likely changed something that causes your mod, betterrecipes.java at line 79 to no longer work correctly.  Likely a function name changed.

    Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

     

    Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

     

    DO NOT PM ME WITH PROBLEMS. No help will be given.

    The strange thing is my eclipse instance is running 1.5.1, It's only when I compile it that I get these errors

    line 79 - 81 is pretty standard code:

    public final Block emptyShelf = new emptyShelf(500, 0, Material.wood)

        .setHardness(1.5F).setStepSound(Block.soundWoodFootstep)

        .setCreativeTab(CreativeTabs.tabDecorations);

    And the bookshelf is pretty simple too:
