Entity table

+

Entity objects

- TODO + Entities are regular tables that get processed by Systems.

+ +

The idea is that entities should only contain data and no code; it’s the systems that are responsible for the actual processing + (but it’s your game, do as you want).

+ +

This data is referred to, and organized in, “components”.

-

Entity system table.

+

Components.

+ Entities are Lua tables, and thus contain key-values pairs: each one of these pairs is called a “component”. The data can be +whatever you want, and ideally each component should store the data for one singular aspect of the entity, for example its position, name, etc.

+

This library does not do any kind of special processing by itself on the entity tables and take them as is (no metatable, no methamethods, etc.), +so you are free to handle them as you want in your systems or elsewhere.

+

Since it’s relatively common for systems to only operate on a single component, as a shortcut the library often consider what it calls the “system component”: +that is, the component in the entity that has the same name as the system (if it exists).

@@ -425,47 +472,97 @@ +

Usage:

+ - - - - - - - -

System objects

- System fields and methods.

+ Systems and Worlds. +Systems are what do the processing on your entities. A system contains a list of entities; the entities in this list are selected +using a filter, and the system will only operate on those filtered entities.

-

When they are added to a world, a new, per-world self table is created and used for every method call (which we call “instancied system”). - Instancied systems can be retrieved in system.s or system.systems.

+

A system can also be created that do not accept any entity (filter = false, this is the default): such a system can still be +used to do processing that don’t need to be done per-entity but still behave like other systems (e.g. to do some static calculation each update).

-

The “world” is just the top-level system, behaving in exactly the same way as other systems.

+

The system also contains callbacks, these define the actual processing done on the system and its entities and you will want to redefine +at least one of them to make your system actually do something.

-

Every field defined below is optional and can be accessed or redefined at any time, unless written otherwise. Though you would typically set them - when creating your system. +

Then you can call System:update, System:draw, System:emit or System:callback at appropriate times and the system will call the +associated callbacks on itself and its entities, and then pass it to its subsystems. In practise you would likely only call these on +the world system, so the callbacks are correctly propagated to every single system in the world.

+ +

Systems are defined as regular tables with all the fields and methods you need in it. However, when a system is added to +a world, the table you defined is not used directly, but we use what we call an “instancied system”: think of it of an instance of your system +like if it were a class. +The instancied system will have a metatable set that gives it some methods and fields defined by the library on top of what you defined. +Modifying the instancied system will only modify this instance and not the original system you defined, so several instances of your system +can exist in different worlds (note that the original system is not copied on instancing; if you reference a table in the original system it will use the +original table directly).

+ +

Systems can have subsystems; that is a system that behave as an extension of their parent system. They only operates on the entities already +present in their parent subsystem, only update when their parent system updates, etc. You can thus organize your systems in a hierarchy to +avoid repeating your filters or allow controlling several system from a single parent system.

+ +

The top-level system is called the “world”; it behaves in exactly the same way as other systems, and accept every entity by default.

+

Usage:

+ 
local sprite = {
+	filter = { "sprite", "position" }, -- only operate on entities with "sprite" and "position" components
+	systems = { animated }, -- subsystems: they only operate on entities already filtered by this system (on top of their own filtering)
+
+	-- Called when an entity is added to this system.
+	onAdd = function(self, component, entity)
+		print("Added an entity, entity count in the system:", self.entityCount) -- self refer to the instancied system
+	end,
+
+	-- Called when the system is updated, for every entity the system
+	process = function(self, component, entity, dt)
+		-- processing...
+	end
+}
+
+local world = ecs.world(system) -- instanciate a world with the sprite system (and all its subsystems)
+
+-- Add an entity: doesn't pass the filtering, so nothing happens
+world:add {
+	name = "John"
+}
+
+-- Added to the sprite system! Call sprite:onAdd, and also try to add it to its subsystems
+world:add {
+	sprite = newSprite("example.png"),
+	position = { x=5, y=0 }
+}
+
+-- Trigger sprite:onUpdate and sprite:process callbacks
+world:update(dt)
