A weighted pressure plate is a block similar in function to regular pressure plates, except only items can activate them, and the number of items on the plate determines the strength of the redstone signal emitted. The weighted pressure plate comes in 2 variants, a light version (gold) and a heavy version (iron).

The light version emits a stronger redstone current for every 4 blocks thrown upon it. It reaches maximum signal when it has 57 items (7 items short of a full stack) upon it.

The heavy version emits a stronger redstone current for every item stack thrown upon it. It reaches maximum signal when it has 598 items (9 full stacks + 22 items) upon it.

The following table will show how many items should be on pressure plate to output a signal of certain strength:

}}
A '''knowledge book''' is a utility item that reveals available [[crafting]] recipes to the player when {{control|used|use}}.

== Obtaining ==
Knowledge books can be obtained only by using [[commands]], as it is not found in the [[creative]] inventory; therefore, it is impossible to obtain in other modes such as [[survival]] and [[adventure]] except with commands.

For example, to give oneself a knowledge book that reveals the recipes for [[bucket]]s and [[flower pot]]s, use: {{cmd|give @s minecraft:knowledge_book{Recipes:["minecraft:bucket", "minecraft:flower_pot"]} }}.

== Usage ==
Knowledge books are used to reveal recipes to the player who uses it, by adding it to their [[recipe book]]. Using a knowledge book consumes it, removing it from the player's inventory.

Knowledge books are especially useful to mapmakers in conjunction with {{cmd|gamerule doLimitedCrafting true}}, because then any item is craftable only if its recipe is unlocked first.

Issues

Issues relating to "Weighted Pressure Plate" are maintained on the bug tracker. Report issues there.

Trivia

  • The pressure plates have the texture of iron and gold blocks. This is most noticeable with the 4 stripes on the iron pressure plate.
  • They are also able to be put on fences and can be used as a fake gold/iron block.
  • The density of gold is nearly two and a half times that of iron, yet it is used to craft the Light Weighted Pressure Plate. However "Light" does not refer to the weight of the plate itself, but how much additional weight is required to get the maximum current.
  • Wooden Pressure Plates are triggered by a single item, effectively making them Very Light Weighted Pressure Plates. However, they are also triggered by entities and arrows, unlike actual weighted pressure plates. Same goes for stone pressure plates, however iTems cannot activate these, making them Ridiculously Heavy Weighted Pressure Plates.
