    Hello.

    I wrote a plugin titled "Slap", which, when the player types /slap <player> [damage], it will broadcast a message to the server (<Slapped player> was slapped by <Slapping player>!), and launch the slapped player in a random direction. (Similar to the slap command in Source Mod, commonly found on TF2 servers)

    I get the following error message when running the command, however:

    The first element in an array is actually 0, not 1.

    So you are checking for a second argument, which there is none of, and executing your code with it, hence the error.

    Just change args[1] to args[0]

    You didn't pay attention when learning about arrays did you?
    In arrays indexes start at 0.

    You didn't change the one on line 29.

    Your code is looking for the second argument (Lines 29 & 32), but you have it check if the arguments length is 1.

    After making some changes to make the plugin Console/Command block compatible, it broke again with a NPE.
