Detailed Description

Quantum entity reference identifies a unique Entity.

Quantum implements a sparse-set ECS model (similar to enTT). This means entities are just references to collections of components.

Most important advantages: memory consumption is proportional to instantiated entities + ability to add and remove components dynamically.

Member Function Documentation

operator==()

static bool Quantum.EntityRef.operator== ( EntityRef  a, EntityRef  b  )

inlinestatic

Operator override for which checks if two instances of EntityRef are equal.

Returns

true if the instances are equal.

operator!=()

static bool Quantum.EntityRef.operator!= ( EntityRef  a, EntityRef  b  )

inlinestatic

Operator override for which checks if two instances of EntityRef are not equal.

Returns

true if the instances are not equal.

Equals() [1/2]

bool Quantum.EntityRef.Equals ( EntityRef  other )

inline

Returns a value indicating whether this instance is equal to a specified EntityRef value.

Parameters

other

An EntityRef value to compare to this instance.

Returns

true if other has the same value as this instance; otherwise, false.

Equals() [2/2]

override bool Quantum.EntityRef.Equals ( object  obj )

inline

Determines whether two object instances are equal.

Parameters

obj	The object to compare with the current object.

Returns

true if the specified object is equal to the current object; otherwise, false.

GetHashCode()

override int Quantum.EntityRef.GetHashCode ( )

inline

Overrides the default hash function.

Returns

A hash code for the current object.

Serialize()

static void Quantum.EntityRef.Serialize ( void *  ptr, FrameSerializer  stream  )

inlinestatic

Serializes a EntityRef into a FrameSerializer to write or read from a frame snapshot.

Parameters

ptr	The pointer to the EntityRef.
stream	The FrameSerializer instance into which the struct will be serialized.

Print()

static void Quantum.EntityRef.Print ( void *  ptr, FramePrinter  printer  )

inlinestatic

Prints the REPLACE using a FramePrinter.

Parameters

ptr	Pointer to REPLACE instance
printer	Printer object

ToString()

override string Quantum.EntityRef.ToString ( )

inline

Converts the numeric value of this instance to its equivalent string representation.

Returns

The string representation of the value of this instance

TryParse()

static bool Quantum.EntityRef.TryParse ( string  str, out EntityRef  result  )

inlinestatic

Try to parse an EntityRef from a string.

Parameters

str	String
result	Resulting EntityRef

Returns

true if the entity ref was successfully parsed

Member Data Documentation

SIZE

const int Quantum.EntityRef.SIZE = sizeof(int) + sizeof(int)

static

The size of the component (or struct/type) in-memory inside the Frame data-buffers or stack (when passed as value parameter). Not related to the snapshot payload this occupies, which is bit-packed and compressed.

IsValid

bool Quantum.EntityRef.IsValid => Raw != 0

Returns false if this entity is equal to EntityRef.None

Index

int Quantum.EntityRef.Index

Entity index.

Version

int Quantum.EntityRef.Version

Entity version is incremented during the entity life cycle when the entity slot is reused.

Property Documentation

Comparer

IEqualityComparer<EntityRef> Quantum.EntityRef.Comparer

staticget

Global Entity ref comparer.

None

EntityRef Quantum.EntityRef.None

staticget

The EntityRef value defining a non-existent Entity.
