Wizar devlog 05 - Advancement on Ravioli

Great advancements on Ravioli this week !

To make it short I am now able to create component instance and add them :

• acceptors
• action
• basic next action predicate

I have also implemented sync, async, cancelable async and composable action.

It remains to implements:

• control state
• more advanced next action predicate
• representation of the model

Here is an example with a mini scenario: A player hits a grunt which auto heals itself twice in reaction.

Next week I will put a live demo online on code sandbox.

test('A player hits a grunt which auto heal itself twice in reaction.', 
  function() {
    const Grunt = component(
      object({ hp: number() })
    )
      .addAcceptor('setHP', model => ({
        mutator({ hp }: { hp: number }) {
          model.hp = model.hp + hp / 2
        },
      }))
      .addActions({
        hit() {
          return [
            {
              type: 'setHP',
              payload: {
                hp: -2,
              },
            },
          ]
        },
        heal() {
          return [
            {
              type: 'setHP',
              payload: {
                hp: 6,
              },
            },
          ]
        },
      })
      .addNAP("double damage", ({acceptedMutations}, {heal}) => {
        const isHit = acceptedMutations.some(({type, payload}) => type === 'setHP' && payload.hp < 0)
        const isHealed = acceptedMutations .some(({type, payload}) => type === 'setHP' && payload.hp > 0)
        if(isHit) {
          console.log("Thrall is hit: -3")
          console.log("Buff double heal")
          heal()
          heal()
        }
        if (isHealed) {
          console.log("Thrall is healed: +6")
        }
      })

  const Thrall = Grunt.create({ hp: 10000 })

  Thrall.actions.hit()

  expect(getData(Thrall).hp).toBe(10003)
  // Battle log:
  // Thrall is hit: -3
  // Buff double heal
  // Thrall is healed: +6
})
