Death Star Challenge datapack by mzxciap.
This datapack works in singleplayer only and in all gamemodes.
No resourcepacks required.
This datapack adds a bar on your screen.
When it says "Targeting..." it is searching for you.
When it says "Firing..." it locks and starts shooting a laser.
When the bar goes down all the way:
When it says "Targeting..." it locks on to a position, and switches to "Firing...".
When it says "Firing..." it fires, deleting blocks and entities (including players in survival) in a 16 block radius, up to the build limit.
It does not kill creative mode players.
When you die, the countdown resets.
The laser only appears when in the "Firing..." phase and is green.
Datapack/bossbar namespace: "dsc:".
Score/tag namespace: "dsc_".
It takes 10 seconds to count down, and 20 seconds to fully target and fire.
The laser makes a beeping noise when firing.
