type CommandOrigin

type CommandOrigin struct {
	// Origin is one of the values above that specifies the origin of the command. The origin may change,
	// depending on what part of the client actually called the command. The command may be issued by a
	// websocket server, for example.
	Origin uint32
	// UUID is the UUID of the command called. This UUID is a bit odd as it is not specified by the server. It
	// is not clear what exactly this UUID is meant to identify, but it is unique for each command called.
	UUID uuid.UUID
	// RequestID is an ID that identifies the request of the client. The server should send a CommandOrigin
	// with the same request ID to ensure it can be matched with the request by the caller of the command.
	// This is especially important for websocket servers and it seems that this field is only non-empty for
	// these websocket servers.
	RequestID string
	// PlayerUniqueID is an ID that identifies the player, the same as the one found in the AdventureSettings
	// packet. Filling it out with 0 seems to work.

	PlayerUniqueID int64
}

CommandOrigin holds data that identifies the origin of the requesting of a command. It holds several fields that may be used to get specific information. When sent in a CommandRequest packet, the same CommandOrigin should be sent in a CommandOutput packet.

type CommandOutputMessage

type CommandParameter

type CommandParameter struct {
	// Name is the name of the command parameter. It shows up in the usage like <$Name: $Type>, with the
	// exception of enum types, which show up simply as a list of options if the list is short enough and
	// Options is set to false.
	Name string
	// Type is a rather odd combination of type(flag)s that result in a certain parameter type to show up
	// client-side. It is a combination of the flags above. The basic types must be combined with the
	// ArgumentTypeFlagBasic flag (and integers with a suffix ArgumentTypeFlagSuffixed), whereas enums are
	// combined with the ArgumentTypeFlagEnum flag.
	Type uint32
	// Optional specifies if the command parameter is optional to enter. Note that no non-optional parameter
	// should ever be present in a command overload after an optional parameter. When optional, the parameter
	// shows up like so: [$Name: $Type], whereas when mandatory, it shows up like so: <$Name: $Type>.
	Optional bool
	// Options holds a combinations of options that additionally apply to the command parameter. The list of
	// options can be found above.
	Options byte

	// Enum is the enum of the parameter if it should be of the type enum. If non-empty, the parameter will
	// be treated as an enum and show up as such client-side.
	Enum CommandEnum
	// Suffix is the suffix of the parameter if it should receive one. Note that only integer argument types
	// are able to receive a suffix, and so the type, if Suffix is a non-empty string, will always be an
	// integer.
	Suffix string
}

CommandParameter represents a single parameter of a command overload, which accepts a certain type of input values. It has a name and a type which show up client-side when a player is entering the command.

	// Count is the total count of the item stack. This count will be shown client-side after the response is
	// sent to the client.
	Count byte
	// StackNetworkID is the network ID of the new stack at a specific slot.
	StackNetworkID int32
}

StackResponseSlotInfo holds information on what item stack should be present in a specific slot.

type StructureSettings struct {
	// PaletteName is the name of the palette used in the structure. Currently, it seems that this field is
	// always 'default'.
	PaletteName string
	// IgnoreEntities specifies if the structure should ignore entities or include them. If set to false,
	// entities will also show up in the exported structure.
	IgnoreEntities bool
	// IgnoreBlocks specifies if the structure should ignore blocks or include them. If set to false, blocks
	// will show up in the exported structure.
	IgnoreBlocks bool

	// Size is the size of the area that is about to be exported. The area exported will start at the
	// Position + Offset, and will extend as far as Size specifies.
	Size BlockPos
	// Offset is the offset position that was set in the structure block. The area exported is offset by this
	// position.
	Offset BlockPos
	// LastTouchedByPlayerUniqueID is the unique ID of the player that last touched the structure block that
	// these settings concern.
	LastTouchedByPlayerUniqueID int64

	// Rotation is the rotation that the structure block should obtain.
	Rotation byte
	// Mirror specifies the way the structure should be mirrored. It is either no mirror at all, left to
	// right mirror or front to back, as the constants above specify.
	Mirror byte
	// Integrity is usually 1, but may be set to a number between 0 and 1 to omit blocks randomly, using
	// the Seed that follows.
	Integrity float32
	// Seed is the seed used to omit blocks if Integrity is not equal to one. If the Seed is 0, a random
	// seed is selected to omit blocks.
	Seed uint32
}

StructureSettings is a struct holding settings of a structure block. Its fields may be changed using the in-game UI on the client-side.

type SwapStackRequestAction

type SwapStackRequestAction struct {
	// Source and Destination point to the source slot from which Count of the item stack were taken and the
	// destination slot to which this item was moved.
	Source, Destination StackRequestSlotInfo
}

SwapStackRequestAction is sent by the client to swap the item in its cursor with an item present in another container. The two item stacks swap places.
