    Hello! So I am creating sign support for my plugin; it works perfectly! All until I destroy the sign afterards,
    I get a NullPointerExeption :/
    StackTrace:
    Caused by: java.lang.NullPointerException
    at me.CraftCreeper6.utilites.InvGUI.onPlayerInteractSign(InvGUI.java:323

    Line 323:
    if (block.getType() == Material.SIGN_POST || block.getType() == Material.WALL_SIGN) {

    It happens with all the created signs and only happens on that line^^ :/
    Any help appreciated!

    You're gonna want to check that it's not null before checking whether it's a sign ;) Just move it from the end to the start

    Did not work :/ It doesn't really cause any havok and you don't get a message in chat so I think it should be fine :p

    CraftCreeper6 Uhh, what errors are you getting? Can I have the full stack trace? Don't feel like looking at the whole class.

    There is one more thing though :/
    Is this randomizer right? (Is it between 1, 4) ?
    Random rn = new Random();
    int max = 4;
    int min = 1;
    int counter = min;
    if (counter <= min) {
    int num = 1 + rn.nextInt(max);
    If not could you please tell me how I would do this? (Don't spoon feed but maybe a thread? (Possibly not Java Docs or BukkitAPI xD I can't understand them :p)) :D

    Stack trace:

    CraftCreeper6 Simplify your random thing. This will generate a random number between 1 and 4, that's what you wanted right?

    PHP:
    int i = new Random().nextInt(4) + 1;
    What're lines 324 and 287 as of that stack trace?
