    Hello

     

    I get this NPE occassionally with my Monk Killer. In the client, there is no info about the NPE (apart from saying there is a NPE, no details about it though) but the console logs the following. What could be the cause of this?

    The two lines of my script is:

     private State getState() {
                    if(getPlayers().myPlayer().getHealthPercent() <= 30)
    48:                     return State.HEALING;
    49:                if(!getLocalPlayer().isInCombat() && getPlayers().myPlayer().getHealthPercent() >= 30)
    50:                return State.ATTACK;
                    return State.FIGHTING;
            }

     

     

     

    55:     public int onLoop() {
    56:       
    57:        switch(getState()){
    58:        case HEALING:
    59:         status = "Healing!";

    I experience this occasionally also. Does it happen at login? Could be because the player object isn't ready when you're trying to run it. When I get home today, I'll look into it, if it hasn't by then. Just got to work :P

    No, this happens at random times while the script is running, and logs me out due to inactivity.

    Try using getPlayers().myPlayer() instead of getLocalPlayer() for now. I believe that's an ongoing issue at the moment

    They both throw the NPE. I originally used getPlayers().myPlayer() but I changed it to getLocalPlayer() to see if that fixed it.
