I’m not a coder and i use playmaker to work in unity, but i see that chatgpt is a good way to get your code done, so i wanted to know how to start so i can try few things with chatgpt.

does the TS automatically creates a C# script?

You open the vscode workspace and create typescript files in src/scripts. There are examples components in the docs and also in the samples that you can download :slightly_smiling_face: when you save the typescript file the component compiler in unity should generate a matching csharp mock component that you can attach to the objects in your scene

It should, some people are reporting that it doesnt do it for them in which case you can also create it manually (it just needs to have the same name and fields as your typescript class). The console in unity also logs the command it uses to generate it. Theres an active post in the forum about that issue. But it usually works like that.

class MyCustomComponent extends Component {
speed = 0;

rotate(angle: number) {
// …
}

update(deltaTime: number) {
this.transform.rotate(this.speed * deltaTime);
}
}

registerComponent(MyCustomComponent);

now if i create a file on vscode then does it need to have same name as class name?

That will not work, please see the reference in Needle Engine Scripting | Needle Engine Documentation. The class needs to subclass behaviour, the method is update(){} and this.transform doesn’t exist. Looks like gpt has produced you some unity code. You also dont need to call registerComponent (thats done automatically be the exporter and the methos doesnt exist like that)

The class name and the filename dont need to match
