ECS For Lua

Context:Init()

  实体拥有Move组件：NewMatcher():AllOf(EMatcher.Move, EMatcher.Camp1)

  实体拥有Move组件但是不能有Stun组件：NewMatcher():AllOf(EMatcher.Move):Noneof(EMatcher.Stun)

AllOf(...)：必须拥有组件

NoneOf(...)：不包含组件
    
AnyOf(...)：包含任意组件，和AllOf规则互斥

Added()：组件添加时

Removed()：组件移除时

Updated()：组件更新数据时，需要使用实体上的UpdateXXX(...)方法才能触发

self.group = Context:GetGroup(NewMatcher():AllOf(EMatcher.Test))

for key, entity in pairs(self.group:GetEntities()) do
    -- do something
end

return {}

return {
    speed = 22,
    direction = {x = 0, y = 0, z = 0},
    isMoving = true
}

local process = {
    TestComponent = "ECS\\Game\\Test\\TestComponent.lua",
    MoveComponent = "ECS\\Game\\Move\\MoveComponent.lua",
    Camp1Component = "ECS\\Game\\Camp1Component.lua"
}

local _Base = require("ECS.Framework.System")
local MoveSystem = class("MoveSystem", _Base)

function MoveSystem:ctor()
    self.group = Context:GetGroup(NewMatcher():AllOf(EMatcher.Test))
end

function MoveSystem:Execute(dt)
    for key, entity in pairs(self.group:GetEntities()) do
        print("move system execute ", entity:HasTest())
    end
end

return MoveSystem

local _Base = require("ECS.Framework.Feature")
local FeatureUpdate = class("FeatureUpdate", _Base)

function FeatureUpdate:ctor()
    self.super:ctor()
    -- 添加system
    self:Add(require("ECS.Game.Move.MoveSystem"))
end

return FeatureUpdate

在Update中调用Feature:Execute(dt)

local e = Context:CreateEntity()
e:AddTest("new  test", { 523 })  -- 执行代码生成后可以使用添加某组件的扩展方法

e:Destroy()
