Wouldnt recommend a sleep as lag and other things can make sleeping not work well or if ur not prepared it can break the script making it think its casted

 

l2sleep.

	new ConditionalSleep(5000, 100) {
			@Override
			public boolean condition() throws InterruptedException {
				return !getTabs().getOpen().equals(Tab.INVENTORY);
			}
		}.sleep();

Also I dont want to wait for the tab to open, I want to start the moving process before it opens up automatically

 

True you could add a hover event til the inventory is open!

Then cache the rectangle slots.
