Iron block Elevator

**This data pack provides you with the function of teleporting upwards while standing on an iron block.** If you encounter any problems, please click (https://github.com/WhiteElephant-abc/anvil-falling/issues/new) to give feedback. ## Main Features ### Iron Block Elevator - Players will be teleported upwards when standing between two iron blocks, one above the other. - The maximum teleportation distance is 6 blocks, which means the maximum distance between the two iron blocks is 5 blocks. - It will not teleport spectators, but it will teleport living and non-living entities. ### Beacon Takeoff - It needs to be enabled by `/scoreboard players set BeaconFly BeaconFly 1`. - It can be disabled by `/scoreboard players set BeaconFly BeaconFly 0`. - When there are iron blocks, gold blocks, emerald blocks, diamond blocks, or netherite blocks (if the game version is 1.21 or above) under the beacon, players will be teleported upwards (spectators will not be teleported). - The heights are 20, 40, 60, 80, and 100 blocks respectively. - Blocks of the same type can be stacked to increase the height (the maximum height is 400 blocks, using four netherite blocks). If the blocks are different, the block closest to the beacon will be used as the reference.
