Entity Type ​

Entities are represented by a special component type, ecr.entity.

This can be used in the same way as custom components types, except instead of representing components, represents entities themselves.

This type cannot be used to modify the registry, methods like add(), set(), remove() do not work with this type.

Get all entities ​

You can get all entities that currently exist in the registry with:

for id in registry:view(ecr.entity) do
    print(id)
end

-- or

local entities = registry:storage(ecr.entity).entities

Exclude-only views ​

You can get all entities without certain components with:

for entity in registry:view(ecr.entity):exclude(...) do end

Listeners ​

You can listen to when an entity is created with:

registry:on_add(ecr.entity):connect(function)

And when an entity is destroyed with:

registry:on_remove(ecr.entity):connect(function)
