This includes:
- [x] `world.getBlocks(x0: int, y0: int, z0: int, x1: int, y1: int, z1: int) -> int[]`
- - Gets all the block ids between x0, y0, z0 and x1, y1, z1
- Gets all the block ids between x0, y0, z0 and x1, y1, z1
- [x] `world.getPlayerId(name: str) -> int`
- - Gets the id of the first player who has the same name as `name`. "Fail" is returned on failure.
- Gets the id of the first player who has the same name as `name`. "Fail" is returned on failure.
- [x] `entity.getName(id: int) -> str`
- - Gets the name of the entity of `id`, as MCPI does not have name tags, it will just be the entity type for non-players
- Gets the name of the entity of `id`, as MCPI does not have name tags, it will just be the entity type for non-players
- [x] `world.getEntities(type: int) -> {id: int, type: int, name: str, x: float, y: float, z: float}[]`
- - returns a list of entities
- Returns a list of entities
- [x] `world.removeEntity(id: int) -> int`
- - removes a single entity and returns 1 if successful
- Removes a single entity and returns 1 if successful
- [x] `world.removeEntities(type: int) -> int`
- - removes all entities of a type, and returns how many were removed
- Removes all entities of a type, and returns how many were removed
- [x] `events.chat.posts() -> {"0", message}[]`
- - gets a list of chat messages, see the limitations section down below to see why it has a zero
- - The messages are not cleared
- Gets a list of chat messages, see the limitations section down below to see why it has a zero
- The messages are not cleared
- [x] `events.projectile.hits() -> {x: int, y: int, z: int, "1", owner: string, target: int}`
- - Returns a list of projectile hit events, the list is cleared each time it is read by this call
- - When target id is not 0, it means the projectile hit an entity and `x, y, z` is the entity's position
- - When target id is 0, it means the projectile hit a block and `x, y, z` is the block's position
- - Unlike RaspberryJuice, the last argument is the hit entity id, not the entity's name. This shouldn't break anything, and indeed should be more useful.
- Returns a list of projectile hit events, the list is cleared each time it is read by this call

- [x] `world.setSign(x: int, y: int, z: int, id: int, data: int, [l1: str], [l2: str], [l3: str], [l4: str])`
- - Sets a block of `id:data` at the specified point, if the block is a sign, it will attempt to set lines 1 through 4 of the sign to the given text
- - For the API, the lines must be below 100 characters, however when loading signs MCPI will cap it at 16 characters (this can be disabled by patching out the call at `0xd1e2c`).
- - The lines are optional
- - The wiki has a list of blocks: https://mcpirevival.miraheze.org/wiki/Minecraft:_Pi_Edition_Complete_Block_List, sign is 63 and wall sign is 68
- Sets a block of `id:data` at the specified point, if the block is a sign, it will attempt to set lines 1 through 4 of the sign to the given text

- [x] `world.spawnEntity(x: int, y: int, z: int, type: int) -> int`
- - Spawns an entity of `type` at the given position
- - Entities with a type of 0 cannot be spawned
- - The list of entity types can be found by running the command below, or on the wiki: https://mcpirevival.miraheze.org/wiki/Minecraft:_Pi_Edition_Complete_Entity_List
- Spawns an entity of `type` at the given position
- Entities with a type of 0 cannot be spawned
- The list of entity types can be found by running the command below, or on the wiki: https://mcpirevival.miraheze.org/wiki/Minecraft:_Pi_Edition_Complete_Entity_List
- [x] `world.getEntityTypes() -> {type: int, name: str}`
- - Returns a list of known entity types, if there are modded entities this list may be incorrect
- Returns a list of known entity types, if there are modded entities this list may be incorrect
- [x] `player.getAbsPos() -> {x: int, y: int, z: int}`
- Gets the absolute position of the player, aka, without passing it through `OffsetPosTranslator`
- [x] `player.setAbsPos(x: int, y: int, z: int)`
- Sets the absolute position of the player, aka, without passing it through `OffsetPosTranslator`
It does not implement (due to MCPI limitations):
- Per-entity events
- Per-player events
- `player.getAbsPos`/`player.setAbsPos` as MCPI already does this
- `events.chat.posts`'s id field is always set to -1
- `events.chat.posts` only returns the last 30 messages, and does *not* clear them after each API call
