    Default Empty If Statement

    So I'm new to these forums, and I was going to do an introduction first, but than I ran over something that really confused me, and I want to know more about it. So I was reading through some decompiled Minecraft code, and I came across this:

    if (!(new WorldGenDungeons()).generate(worldObj, rand, k2, k3, i4));

    So as I see it, generate returns whether or not a dungeon has successfully made. So what is the purpose of this statement? If it helps, this is at the end of a for loop that runs 8 times.

    You'll have to ask the author of the code why he wrote that statement to get its purpose.
    If you don't understand my answer, don't ignore it, ask a question.

    Since I can't contact the author easily, let me rephrase the question...Doesn't that statement do nothing? I don't see how that statement could get anything accomplished.

    I'm not too sure about that either, quite strange. I've never seen anybody purposely write something like that.

    It looks like it creates an instance of a class and calls a method of that class which returns a boolean value used by the if statement to control execution flow.

    It creates the instance of the class and calls the generate function, but the actual boolean value looks like it is discarded, as the if statement doesn't do anything. This is confusing...Though this code was written back in...I don't know...Infdev? When Notch was just programming it by himself and had really bad habit.
