dev.atedeg.ecscala.dsl

This trait provides a domain specific language (DSL) for expressing the ECScala framework operations using an english-like syntax. Here's the things you can do:

'''Create an entity in a world:'''

val world = World()
val entity1 = world hasAn entity

'''Remove entities from a world:'''

 *  world - entity1
 *  remove (entity1) from world
 *  remove (List(entity1, entity2, entity3)) from world

'''Create an entity in a world with a component:'''

val entity1 = world hasAn entity withComponent MyComponent()

'''Create an entity in a world with multiple components:'''

val entity1 = world hasAn entity withComponents {
     MyComponent1() &: MyComponent2() &: MyComponent3()
}

'''Add components to an entity:'''

 *  entity1 + MyComponent()
 *  entity1 withComponent MyComponent()
 *  entity1 withComponents { MyComponent1() &: MyComponent2() }

'''Remove components from an entity:'''

 *  remove { MyComponent() } from entity1
 *  entity1 - MyComponent()
 *  remove { MyComponent1() &: MyComponent2() &: MyComponent3() } from entity1

'''Add a system to a world:'''

world hasA system[MyComponent &: CNil] { (_,_,_) => {}}

'''Get a view from a world:'''

 val view = getView[MyComponent1 &: MyComponent2 &: CNil] from world

'''Remove all entities and their components from a world:'''

 clearAll from world
