It can be really frustrating if you want to switch back and forth between Scratch, Python and Minecraft, as Minecraft will automatically pause when you leave the window. While this is good when you’re playing normally, it stops us from seeing what’s happening in the Minecraft window when we’re working elsewhere. Follow these instructions to stop Minecraft from pausing.

  1. Navigate on your computer to your Minecraft folder. Remember that you can always find out where that is by opening up the Minecraft Launcher and clicking on ‘Launch Options'

  1. Open up the options.txt file in a text editor(img)

  2. Search for a line that reads: pauseonLostFocus:False, and change it to read pauseonLostFocus:True (img)Save and close options.txt

  1. Open Minecraft back up.

Now you’ll find that when you ALT-TAB (Win) or CMD-TAB (Mac) away from Minecraft to another program, Minecraft won’t pause on you.

Another Tip

Minecraft can be pretty resource intensive on any computer that you're running. I'd advise to turn some of the advanced graphic features down or off, as indicated by the screenshot below.
