Hey I'm new to the bot scene and I'm currently struggling with a nullpointerexception.

Quote

    public static void HopWorldRandom() throws InterruptedException {
        int CurrentWorld = script.getWorlds().getCurrentWorld();
        int HoptoWorld = WORLDS[MethodProvider.random(WORLDS.length)];
        while(CurrentWorld == HoptoWorld) {
            HoptoWorld = WORLDS[MethodProvider.random(WORLDS.length)];
        }
        final int HoptoWorldfinal = HoptoWorld;
        script.log("Hopping to world: "+HoptoWorld);
        
        if(script.worlds.hop(HoptoWorld))
        new ConditionalSleep(MethodProvider.random(10000, 10000)) {
            @Override
            public boolean condition() throws InterruptedException {
                return CurrentWorld == HoptoWorldfinal;
            }
        }.sleep();
    }

It works for a couple of hours before I get a nullpointerexception and then it doesn't, any ideas?

WORLDS[] is simply an array of worlds to choose from when randomly hopping.

I think I found a bug, I'm trying this now and so far so good:

    public static void HopWorldRandom() throws InterruptedException {
        int CurrentWorld = script.getWorlds().getCurrentWorld();
        int HoptoWorld = WORLDS[MethodProvider.random(WORLDS.length-1)];
        while(CurrentWorld == HoptoWorld) {
            HoptoWorld = WORLDS[MethodProvider.random(WORLDS.length-1)];
        }
        final int HoptoWorldfinal = HoptoWorld;
        script.log("Hopping to world: "+HoptoWorld);
        
        if(script.worlds.hop(HoptoWorld))
        new ConditionalSleep(MethodProvider.random(10000, 10000)) {
            @Override
            public boolean condition() throws InterruptedException {
                return CurrentWorld == HoptoWorldfinal;
            }
        }.sleep();
    }

 

Any tips on how to detect if I've hopped world?
return CurrentWorld == HoptoWorldfinal;
Is really slow.

Solved it I think, here's the final code if someone needs it in the future:

        int CurrentWorld = script.getWorlds().getCurrentWorld();
        int HoptoWorld = WORLDS[MethodProvider.random(WORLDS.length-1)];
        while(CurrentWorld == HoptoWorld) {
            HoptoWorld = WORLDS[MethodProvider.random(WORLDS.length-1)];
        }
        final int HoptoWorldfinal = HoptoWorld;
        script.log("Hopping to world: "+HoptoWorld);
        
        if(script.worlds.hop(HoptoWorld))
        new ConditionalSleep(10000, MethodProvider.random(1000, 2000)) {
            @Override
            public boolean condition() throws InterruptedException {
                return CurrentWorld == HoptoWorldfinal;
            }
        }.sleep();
    }

 

        new ConditionalSleep(MethodProvider.random(10000, 10000)) {
            @Override
            public boolean condition() throws InterruptedException {
                return CurrentWorld == HoptoWorldfinal;
            }
        }.sleep();

that will never work since you never update the values. do this instead

        new ConditionalSleep(MethodProvider.random(10000, 10000)) {
            @Override
            public boolean condition() throws InterruptedException {
                return script.getWorlds().getCurrentWorld() == HoptoWorldfinal;
            }
        }.sleep();

That is true, Thanks!

I don't think this will will solve the nullpointerexception error but it's a step in the right direction.
