Put down a Lifecycle. Connect it to a Relay. Connect the Relay to a Trigger.
Make sure you have the following options for the Trigger:
Create a block for the Trigger, when triggered…
Switch “Your Name” to whatever name you usually join games with.
But what happens when receiving on channel godMode?
Well, that’s up to you. You could change your speed to 4. Or you could teleport to a shop with tons of free upgrades. Or you could just give yourself health regeneration. It’s up to you.
Just make sure other people don’t figure out how you do it, or they’ll join with your name, and also get God Mode. If you want, you can make a super expensive Vending Machine that gives you God Mode. They’ll think that’s how you got it, and they’ll focus on trying to buy it. Hint: it’s impossible.
