Entity References

In some cases, you may want to reference entities among themselves. Instead of an Entity you should refer to an EntityReference instead. This references an entity and also stores a version to check if the original entity still exists.

using var world = World.Create();

var entity = world.Create(_entityGroup);
var reference = world.Reference(entity);  // This should be stored in your component ( entity.Reference() is also available. )

// Checks if the entity is the same as before by comparing the version and its id
if(reference.IsAlive()) {
    var cmps = reference.Entity.Get(...);
}
