	Type uint16
	// Abilities is a set of abilities that are enabled for the layer. This is one of the Ability constants defined
	// above.
	Abilities uint32
	// Values is a set of values that are associated with the enabled abilities, representing the values of the
	// abilities.
	Values uint32
	// FlySpeed is the default fly speed of the layer.
	FlySpeed float32
	// WalkSpeed is the default walk speed of the layer.
	WalkSpeed float32

type Attribute 

type Attribute struct {
	// Name is the name of the attribute, for example 'minecraft:health'. These names must be identical to
	// the ones defined client-side.
	Name string
	// Value is the current value of the attribute. This value will be applied to the entity when sent in a
	// packet.
	Value float32
	// Max and Min specify the boundaries within the value of the attribute must be. The definition of these
	// fields differ per attribute. The maximum health of an entity may be changed, whereas the maximum
	// movement speed for example may not be.
	Max, Min float32
	// Default is the default value of the attribute. It's not clear why this field must be sent to the
	// client, but it is required regardless.
	Default float32
	// Modifiers is a slice of AttributeModifiers that are applied to the attribute.
	Modifiers []AttributeModifier
}

Attribute is an entity attribute, that holds specific data such as the health of the entity. Each attribute holds a default value, maximum and minimum value, name and its current value.

type AttributeModifier 

type AttributeModifier struct {
	// ID is the unique ID of the modifier. It is used to identify the modifier in the packet.
	ID string
	// Name is the name of the attribute that is modified.
	Name string
	// Amount is the amount of difference between the current value of the attribute and the new value.
	Amount float32
	// Operation is the operation that is performed on the attribute. It can be addition, multiply base, multiply total
	// or cap.
	Operation int32
	// Operand ...
	// TODO: Figure out what this field is used for.
	Operand int32
	// Serializable ...
	// TODO: Figure out what this field is used for.
	Serializable bool
}

AttributeModifier temporarily buffs/debuffs a given attribute until the modifier is used. In vanilla, these are mainly used for effects.

type AutoCraftRecipeStackRequestAction 

type AutoCraftRecipeStackRequestAction struct {
	// RecipeNetworkID is the network ID of the recipe that is about to be crafted. This network ID matches
	// one of the recipes sent in the CraftingData packet, where each of the recipes have a RecipeNetworkID as
	// of 1.16.
	RecipeNetworkID uint32
	// TimesCrafted is how many times the recipe was crafted.
	TimesCrafted byte
}

AutoCraftRecipeStackRequestAction is sent by the client similarly to the CraftRecipeStackRequestAction. The only difference is that the recipe is automatically created and crafted by shift clicking the recipe book.

}

CommandEnum represents an enum in a command usage. The enum typically has a type and a set of options that are valid. A value that is not one of the options results in a failure during execution.

type CommandEnumConstraint 

type CommandEnumConstraint struct {
	// EnumOption is the option in an enum that the constraints should be applied to.

	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

	// 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

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 CommandOutputMessage struct {
	// Success indicates if the output message was one of a successful command execution. If set to true, the

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.

	// ID was present, and is one of the concrete types below.
	Actions []StackRequestAction
	// FilterStrings is a list of filter strings involved in the request. This is typically filled with one string
	// when an anvil or cartography is used.
	FilterStrings []string
}

type ItemStackResponse 

type ItemStackResponse struct {
	// Status specifies if the request with the RequestID below was successful. If this is the case, the
	// ContainerInfo below will have information on what slots ended up changing. If not, the container info
	// will be empty.
	// A non-0 status means an error occurred and will result in the action being reverted.
	Status uint8
	// RequestID is the unique ID of the request that this response is in reaction to. If rejected, the client
	// will undo the actions from the request with this ID.
	RequestID int32
