Animations, Sprites, Scene | Unity3d + BrighScript engine to run exported resources

Hello All, I'm interesting in feedback on my new Unity + Roku project. 

Whole idea is to make Unity3d Editor as main asset editor with support of animations and object tree (scenes/prefabs).  

I will put part of my project guide pdf, I need your opinion how to push this project! thank you.

How many of you know Unity3d?



After few projects on Roku platform it was clear that making robust animation is really complex and some even impossible. Unity3D provide great platform to create game assets as well as re-import existing assets from massive Unity Assetstore. Roku Yov – is unity editor plugin which provide set of tools to re-import existing “pure” unity assets including animation and export to resources which will used on Roku device. The “Roku Yov” unity package provided with code on BrightScript which load and execute exported resources on Roku device.


Roku device

Please follow official guide: After you complete the setup of your Roku device make sure that your developer PC or Mac connected to the same WiFi network as Roku device and you know Roku device IP address.

Developer PC or Mac

On your developer machine you will require to installed: Unity 19.4.0.f1, latest VSCode from Inside VSCode you have to install “BrightScript Language” extension to support debugger and deploy to your Roku device.

Package setup

After you did receive/install the Roku Yov and import into your Unity Editor (19.4.0.f1) you would have already setup project which you could learn from about provided tools of Roku Yov.


First step which you need to be done is to unpack `Assets/Roku/` to any folder out of unity project for example to user `Documents` folder. As result you will get folder `~/Documents/roku` which contain pre-setup Roku project folder. This folder need to be open with VSCode. Next step is VSCode `launch.json` file modification of host and password fields shown at image below with IP address of your Roku device, in my case it’s your Roku device IP address you could find on Roku device itself (Settings→Network→About→ IP address).



Setup is done. Now you could hit Run (F5) and run build on Roku device.

BrightScript Code Archive Explain (

This part of this document explain content of archive which you unpack from Assets/Roku/

roku/ - root folder


------------/launch.json – vscode configuration file which explain how to build and run project

----/animations/ – contain exported animations from Unity Roku plugin.

---------------/game_hide.json – UI animation controls show/hide game root node.

---------------/kid_idle.json, kuzya_eye.json, kuzya_idle.json etc…


----------/yov.ttf - game font exported from Unity plugin.

----/icons/ - not exported part which used in manifest file






----/out/ - authogenerated build output, set in launch.json.

----/prefabs/ - roku plugin exported semi-objects with the same idea as Unity prefabs

behind – create/clone an object from it on fly.

------------/Border0.json - as example prefab of border section which created multiple times to create

a line

----/scenes/ - exported unity scenes to load in game

-----------/MainScene.json – main scene of the game.

----/source/ - not exported part, contains BrighScript code for game and engine.

-----------/Functions/ - behavior function attached on node objects (aka GameObject in Unity)

---------------------/GameFunc.brs – game logic and UI part.

---------------------/ActorsFunc.brs, MenuFunc.brs, etc…

-----------/RokuEngine/ - roku engine code




-----------/App.brs - application code

-----------/Main.brs - main file, roku start from here!

----/sprites/ - exported sprite files.

------------/allsprites.png – atlas image


----/collection.json - exported file, has all descriptors of all exported resources like

aniamtions, sprites, fonts, prefabs and scenes.

----/config.json - Roku native config file.

Re: Unity3d + BrighScript engine to run exported resources

"Roku Yov" - it's just name of the package which I submit for approval on Unity Assetstore, it be online in a few weeks.

What it's for? ->

1. to make UnityEditor as resource editing tool with support of export existing pure Unity assets portable for Roku device.

2. It's provide BrightScript project with ready made mathematics to run exported animation from Unity.

3. It's grab UnityEditor scene object hierarchy and export to scene.json files as well as prefabs.

4. Preparing atlas images from images resources.

5. It's half made example game which ready to run and learn from it.

In general it's new vision how to make game projects on Roku with more user friendly UnityEditor as resource container and exporter and strong powerful BrightScript to run those resources on Roku device.

I will record tutorial videos soon, it be more clean and you will like it 🙂

I did quick video .

Let me know, is it good explanatory ? 

What is missing in overview or where it need to be focus on?

Thank you!

Wow, this is interesting and perhaps promising for future Roku game development.

Re: Unity3d + BrighScript engine to run exported resources

Do you think I have to promote as standalone solution (website+company) or leave it as public asset on Unity asset store? How to promote through Roku developer community this solution? Where developers searching for examples or tools? Where a roku developer could find information about this tool?

I'm just join a few years back to Roku and still lost how does community structured, but I'm not newbie in the game 🙂 I have 15+ years of experience in game development.

Sadly there's not much of a game dev community for Roku. And this, while it looks impressive and promising, is beyond me at the present.

Re: Animations, Sprites, Scene | Unity3d + BrighScript engine to run exported resources

I need to sell as standalone solution or depart it as public asset on Unity asset website store? How to sell thru Roku developer network this solution? Where builders trying to find examples or equipment?
