|
|||
### Components
|
||||
The most "bare metal" are the components. These are essentially hooks into the engine that tell it how to do particular things. For example, to render a sprite, Javascript does no rendering, but rather tells the engine to create an image and render it in a particular spot.
|
||||
|
||||
Components are rendered in an "ECS" style. To work, components must be installed on an entity.
|
||||
Components are rendered in an "ECS" style. To work, components must be installed on an entity. They have no meaning outside of a physical object in the world.
|
||||
|
||||
AI would be components. You could have a "sensor" AI component that detects the world around it, and a locomotion AI component, etc, and reserve scripting for hooking them up, etc. Or do it all in scripting.
|
||||
|
||||
Components cannot be scripted; they are essentially a hardwired thing that you set different flags and values on, and then can query it for information.
|
||||
|
||||
### Entity
|
||||
Entities are holders of components. Anything that needs a component will be an entity. Components rely on entites to render correctly. For example, the engine knows where to draw a sprite wherever its associated entity is.
|
||||
|
||||
### Levels
|
||||
Levels are nothing more than groups of entities However, levels can also have a script on them. This level of scripting is the least efficient.
|
||||
Entities can be composed of other entities. When that is the case, an entity "under" a different entity will move when the above entity moves.
|
||||
|
||||
Levels do not have an associated gameobject inside the engine, and so are what you want if you just want to run some code.
|
||||
The outermost entity that all other entities must exist in is the Primum. It always exists and cannot be removed.
|
||||
|
||||
## Traits
|
||||
It is better to think of Primum as trait-based, intead of object-based. Any thing in your game that has particular properties can be used as a particular sort of object.
|
||||
|
||||
## Prototyping model
|
||||
All objects follow the prototyping model of inheritence. This makes it trivial to change huge swathes of the game, or make tiny adjustments to single objects, in a natural and intuitive way.
|
||||
|
||||
Components cannot be prototyped. They are tied directly to the entity they are bound to.
|
||||
Components cannot be prototyped. They are fundamentally tied to the entity they are bound to.
|
||||
|
||||
Entities can be prototyped out. What this means is that, when you select an object in the game, you can either make a "subtype" of it, where changes to the object trickle down to the created one, or a "sidetype" of it, which is a total duplicate of the object.
|
||||
|
||||
entity.clone(parent) -> create a subtyped version of the entity
|
||||
entity.dup(parent) -> create a copy of the entity.
|
||||
entity.promote() -> promote the entity to a new Ur-type, as it currently exists.
|
||||
entity.revert() -> remove all changes of this entity so it again matches its Ur-type.
|
||||
entity.push() -> push changes to this entity to its Ur-type to it matches.
|
||||
|
||||
### Ur-types
|
||||
An Ur-type is a thing which cannot be seen but which can stamp out copies of itself. Objects can be promoted to an ur-type, so if it is deleted, another one can later be made.
|
||||
|
||||
Levels can be subtyped, sidetyped, and urtyped, just like entities.
|
||||
|
||||
## Resources
|
||||
Assets can generally be used just with their filename. It will be loaded with default values. However, how the engine interprets it can be altered with a sidecar file, named "filename.asset", so "ball.png" will be modified via "ball.png.asset". These are typical JSON files. For images, specify gamma, if it's a sprite or texture, etc, for sound, specify its gain, etc.
|
||||
|
||||
## Level model
|
||||
The game world is made up of objects. Levels are collections of
|
||||
objects. The topmost level is called "World". Objects are spawned into
