Hi,
I am working on a opensource ecs game engine and I wanted to replace the current custom network management with Colyseus !
But, ECS means that my game is composed by several Entity that can have 0 to many components. A Component is assigned to an Entity by putting him into a Entity.components object holding them by their names.
I am not very familiar with the Schema aspect, how can I bring this data structure into Colyseus ?
Idea 1 :
Define types during runtime with defineTypes, something like :
const entity = new Entity() // Entity extends empty Schema
entity.addComponent(new MyComponent()) // MyComponent extends Schema with data structure
// The second line will run this :
schema.defineTypes(entity , {
MyComponent: MyComponent
});
But, well ... Schema defines types in object prototype (https://github.com/colyseus/schema/blob/master/src/annotations.ts#L283) not instance ... so it will not work as each Entity instance may have different Components.
Idea 2 :
Sending maps of Components for each Entity (preferred solution as I already have a Entity.components attributes.
class Entity extends Schema {
@type({ map: Components})
components = new MapSchema<Components>();
}
But again I think it will not work because the engine will store different Component data structures. Examples : PositionnableComponent with x, y, angle, HealthComponent with current, maximum, etc ...
