I am wondering if it is possible to port a game developed in Touch Develop to MakeCode Arcade? I have the JSON files of a project I made, called ‘Spacey Invaders Reloaded’. Does anyone know of a lexical parser to converts the JSON content into Static TypeScript?

Interesting idea, @cosmoscowboy! MakeCode Arcade is the spiritual successor to Touch Develop, but it’s a very different platform.
If you’re willing to share your JSON, I’d be happy to take a look. I don’t think I have any of my old Touch Develop code anymore.
Any initial thoughts, @peli ?

Hi @AlexK,
Thank you for your reply. I have this file which contains functions for calculating Bezier curves. I can strip out the code that was in the format of Touch Develop, and manually write that as TypeScript; that is not a problem. I just though maybe, since Touch Develop code was translated to TypeScript, and that to Javascript, that there is a library somewhere that enables that process.

What fun code! I love it.
It’s also fun to see Touch Develop code again. It’s been a _very_ long time for me. I’ve forgotten how different the language is; it’s much more like Pascal.
I’d be interested to see if any of the code for the Touch Develop parser still exists. I don’t think this can be done with a simple line-by-line transpiler, since the Touch Develop environment is so different from the MakeCode Arcade environment.
I’m going to ponder on this and stare at your code a bit more to see how I’d approach this. In the meantime, perhaps we’ll hear from members of the Touch Develop team with their thoughts and perspective.

Thanks Alex,
I used the Bezier curves to move the enemies in a space invaders game. I would like to make this again, but also to make extensions so that others might be able to use the animations. TypeScript is new for me, as is Javascript, but with experience in C#, the transition shouldn’t be too hard. Any help in parsing this is appreciated, even if it is only formatting the Touch Develop code into something readable.

Well, at the very least, I can help you with that last request!

That is fantastic Alex! That makes the code much more readable, and I am really impressed with quick response.
Is there any chance I could send you the rest of the code? I have another 5 files.
I don’t mind that others see the code, since this platform is all about sharing code and being open-source. If I can send the other files, would it be better to send them via email?

I’m a C# coder at heart, too. JavaScript and, even more so, TypeScript are easy languages to pick up with that background. The thing that sometimes gets me is the peculiar syntax that JavaScript has for declaring variables. I keep wanting to write them the C# way and IntelliSense keeps yelling at me. 😄
I’ll give you time to port your code. I find it’s a great way to learn a language. Please feel free to ask for help if you need any.
There are several nice documents in the MakeCode documentation about creating extensions. Once you’ve ported your code, I’ll be happy to help you with creating extensions.
* * *
Regarding your other files, we could work on them together via GitHub if you’d like. You can find me there as **alex-kulcsar**. Might be the best way to collaborate on this code if we treat it like a project. Since you’re porting your code to MakeCode Arcade, that might be the best way to start.
- Create a GitHub project within MakeCode Arcade.
- Add the Touch Develop code to your new project via the GitHub web site.
- Invite me as a collaborator.

I agree with you on the quirkiness of the syntax; but I also see that as an advantage in offering flexibility.
Working on the code together in GitHub sounds like a good idea; I will get back to you on that. To be honest, I am somewhat of an amateur to GitHub, since I have been cradled using tools such as Visual Studio and Bitbucket. I will keep in touch.

Just in case you need it, here’s MakeCode Arcade’s documentation. MakeCode Arcade makes it pretty easy to work with GitHub, too.

I have indeed logged into my GitHub account and linked that to MakeCode. I am quite impressed with what MakeCode already offers in terms of integration. I will be taking baby steps with MakeCode, to first familiarize myself with the block code, and then moving on to creating extensions.
I am also curious as to how you formatted the Touch Develop code. Was that done using something from the old platform, of did you just simply use something that parses the string value?

I don’t understand why the code does not work with blocks, maybe I need to add markdown for certain functions.

Yup; baby steps are a good thing! If you’re comfortable with the TypeScript environment, then, at least for this project, you probably want to stay there…especially if you’re planning on writing an extension. You can worry about the Blocks parts later. (Short answer: The TS code needs to be both structured and then annotated in a specific way in order for blocks to appear in the toolbox.)
You’ll definitely want to get into the Blocks environment, though, to gain an understanding of the interface before you try to develop an extension. I’d suggest using the Blocks tutorials in the **Tutorials** or the **Game Design Concepts** sections of the home page. They’re great introductions to the MakeCode Arcade interface, and they provide you with a bit of a glimpse into the philosophy behind the MakeCode Arcade project.
Regarding your Touch Develop JSON: I cheated. 🙂 All I did was load your code into a text editor and then replace `\n` with an actual newline. I’m not a Microsoft employee, past or present, and so I don’t have access to the Touch Develop source code. I’m simply a user and massive fan of both platforms…and a _very occasional_ contributor to the MakeCode Arcade platform.

@AlexK
I was able to get part of the code working in blocks. I know that the annotations are not entirely correct. I took a shortcut and used examples from the game extension (sprites.ts & sprite.ts). I will take a look at the documentation:
> **[Defining blocks](https://makecode.com/defining-blocks)**
>
> This section describes how to annotate your MakeCode APIs to expose them in the Block Editor.
[https://makecode.com/playground](https://makecode.com/playground)
For now it is so much information, I need to let it all sink in.

We had some code to convert touchdevelop programs… but it’s long gone now sorry.

That is a pity; as that would have saved my a lot time recreating old games. Was ‘that code’ for converting block code, or written code? I’m sure someone has the tool lying around somewhere.
