Beacon

The beacon block (referred to as Work in Progress in-game) is a block that when placed as the final block on top of a pyramid formation made up of diamond, emerald, gold or iron blocks (or any combination of the 4), will emit a beam of light into the sky. The block may also provide temporary buffs to players within radius of the block if chosen in the block's GUI. The pyramid formation that the beacon block sits on top of must be one to four blocks in height (not including the beacon block) otherwise the beacon block will have no effect. The smallest pyramid that can be made to work with the beacon block has 1 level and consists of 9 mineral blocks.

Usage


When the player crafts blocks of diamond, emerald, gold or iron and places them in a pyramid shape beneath the beacon block, it will emit a beam of light into the sky and can apply temporary buffs to the player once activated. The more levels a pyramid has, the more effects it can apply. There are currently 4 levels of pyramids. Not counting the Beacon Block, the first pyramid requires 9 blocks, the second, 34 blocks, the third, 83 blocks, and the final arrangement, 164 blocks. A Secondary Power is a power that can be added onto a primary power. The "Regeneration" power is always visible. It is possible to mix and match the blocks used in the pyramid. (Both emerald and diamond blocks may be used together, for example.)

The beam of light is visible from up to 256 blocks away, and is even visible in unloaded chunks. This provides a useful marker for short to mid-range gameplay.

Requirements/effects
The beacon block requires that there be no blocks above it (exceptions: enchanting tables, enderportal frames, chest, enderchest, blocks that you can walk through, glass panes, iron bars, pistons.), and a light level of 15 (it does not have to be day time). This does not apply to the pyramid itself.

Effects will be applied to the player while within a radius of the beacon, with larger pyramids giving larger areas-of-effect. The radius is approximately 16 blocks, 24 blocks, 32 blocks, and 40 blocks from the smallest pyramid to the largest. The radius takes the player's y-coordinate into account.

Activation
The beacon provides no powers by default. To activate it, place either an iron ingot, a gold ingot, an emerald or a diamond into the GUI slot. The player can set the power by clicking on the top window: clicking on an effect will activate it. The item will be consumed and the beacon begin providing the power to nearby players when "Done" is clicked. To set a beacon to a different power, another item must be consumed.

Powers
If the pyramid is damaged so that the beacon loses power, the beacon will still remember what powers it was set for and, once the pyramid is repaired, will resume its previous function at no additional resource cost. This applies to pistons as well, making it possible for players to build beacons that can be turned on and off with a sticky piston removing or replacing a block on the pyramid.

Primary powers
The five primary powers are Speed, Haste, Resistance, Jump Boost, and Strength. One primary power must be selected to activate the beacon.

Secondary powers
The only purely secondary power is Regeneration. Secondary powers also provide level II variations of primary powers when selecting that primary power. When selecting the level II variant, regeneration is no longer provided by the beacon.

Other dimensions
The beacon will function partially (no light beam but it will provide powers) within the Nether as long as there are at least fourteen empty blocks above it. Pyramid size has no effect on this distance. This is possibly a glitch as breaking through the bedrock ceiling, causing the light beam to appear, and subsequently filling the hole will prevent this from working.

The beacon functions normally in The End.

Bugs

 * [Critical] Activating a full beacon pyramid without utilizing one of the secondary powers will cause the world to disconnect with an "Internal Server Error". The world will no longer be accessible, always returning this error when access is attempted. The problem can be solved by erasing every .data of the players in range of the beacon block. This will erase their inventory, and move them to the spawn.
 * Destroying a beacon block containing resource(s) destroys the resource. (The beacon block still drops, just not its contents.)
 * Clicking on the beacon block within 4 seconds of placing it sometimes results in an empty beacon GUI.

Trivia

 * The beacon block's current sprite is only a placeholder and will be changed when it is officially released. It might use a different model than a block as well.
 * The beacon light generated from the beacon block is 255 blocks tall. It is relative to the beacon block height, so several beacon block beam can stop at different heights.
 * The beacon light is the same style as lightning.
 * Some blocks like signs are very visible even when seen through several beams, becoming a lot more distinguishable from the rest of the landscape.
 * The beacon light does not disappear until the chunk is unloaded, providing a great means to judge where places are.
 * Adjacent beacons may share blocks in their pyramids, allowing for fairly efficient designs that provide multiple powers.
 * The most efficient design allowing for all powers to be activated at the highest level requires 244 blocks, rather than 984 if the beacons were separate. This is more than a 75% reduction in materials necessary.
 * The player can leave a resource in the beacon block without clicking "Done.".
 * The only blocks that can be placed in the beacon's light without deactivating the beacon are glass, glass panes, enchanting tables, ender portal frames, enderchests, pistons and piston arms.
 * Like other light sources with a luminosity over 12 the Beacon Block's light is powerful enough to melt ice.
 * The enhancements last 8 seconds each
