This worked. The confusion happened because I called my own variable for the bank chest "bank". Thanks. What do you mean by call new ConditionalSleep? Am I not calling it by making a new instance of it?

Right, I wasn't even paying attention to the condition so that makes sense. However I tried it and the lagging still happens.

Haven't scripted (or programmed) in years and started again today. I just found that adding a check to see if my bank is open makes my script lag and unusable. I remember this was usually caused by executing some CPU intensive instruction in a loop but surely it's normal that this type of check is placed in a loop? This is the relevant code (don't mind the conditional sleep, it's not finished): RS2Object bank = getObjects().closest("Bank chest"); if (inventory.isFull() && !b.isOpen()) { if (bank != null && bank.isVisible()) { bank.interact("Use"); new ConditionalSleep(random(800, 1500)) { @[member=Override] public boolean condition() throws InterruptedException { return false; } }; } } b is simply an instance of the Bank class. Thanks in advance.
