23w13a_or_b less_interaction_updates Vote Rule

Warning: April Fools' 

This feature requires April Fools' versions and may require the use of file modifications to load. See the tutorial for information on loading these versions.

In april fools' snapshot 23w13a_or_b, you can obtain a floating lever with the less_interaction_updates vote rule. First, vote for the less_interaction_updates rule. Then, place a lever on any block. After that, simply break the support block below the lever. This will result in the lever floating due to the suppression of interactions between blocks.

Update Suppression

By suppress lever support block update, when the support block is broken, the lever will float.

An additional way to obtain a floating lever is with vanishing blocks. Simply perform vanishing blocks so the support block below the lever disappears. This will result in the lever floating.

Update Skipping

Warning: April Fools' 

This feature requires April Fools' versions and may require the use of file modifications to load. See the tutorial for information on loading these versions.

In April Fools' snapshot 24w14potato, it was possible to remove support block without causing any block updates using the Floatater.^[2]

1. Place the support block and lever in a position with no blocks around.
2. Place a Floatater block with the green sticky side facing sideways into support block. Make sure there are still no blocks touching the contraption.
3. Power the opposite side of the Floatater, or the trigger side.
4. The Floatater and support block will start moving away from its original location, not causing any block updates to the level.
