Lua实现 加载场景Loading进度

废话不多说 直接上代码！

local async = UnityEngine.SceneManagement.SceneManager.LoadSceneAsync(sceneName)
ShowLoadingAsync(async)

---异步显示loading进度
local function ShowLoadingAsync(async)
    local toProgress = 0
    local displayProgress = 0
    async.allowSceneActivation = false
    while (async.progress < 0.89) do
        toProgress = async.progress * 100
        while (displayProgress < toProgress) do
            displayProgress = displayProgress + 1
            this.LoadingProgress = displayProgress / 100.0
            LogicEventDispatcher.SendWithArgs(LogicEventType.LoadSceneProgress,this.LoadingProgress)
            coroutine.step()
        end
        coroutine.step()
    end

    toProgress = 100
    while (displayProgress < toProgress) do
        displayProgress = displayProgress + 1
        this.LoadingProgress = displayProgress / 100.0
        LogicEventDispatcher.SendWithArgs(LogicEventType.LoadSceneProgress,this.LoadingProgress)
        coroutine.step()
    end
    async.allowSceneActivation = true
    this.LoadingProgress = 1.0
end

把async.allowSceneActivation设置为false后，Unity就只会加载场景到0.9，那0.1要等到async.allowSceneActivation设置为true后才加载。所以当async.progress到达0.9后，我们手动设置进度条的数值1，然后设置async.allowSceneActivation为ture，让Unity继续加载那10%的场景,显示上做了一个平滑处理。lua代码为纯手打，第一次写博客，有不对的地方欢迎指正。
