MeshBuilder.CreateLineSystem() TS errors

[inteja]

Following docs here https://doc.babylonjs.com/how_to/parametric_shapes#line-system

And links PG here http://www.babylonjs-playground.com/#165IV6#66

If I attempt this (verbatim cut'n'paste) in my own TS project, it results in compile error:

error TS2345: Argument of type '{ lines: Vector3[][]; }' is not assignable to parameter of type '{ lines: Vector3[][]; updatable: boolean; instance: LinesMesh; colors?: Color4[][]; useVertexAlph...'.
  Property 'updatable' is missing in type '{ lines: Vector3[][]; }'

http://doc.babylonjs.com/api/classes/babylon.meshbuilder#createlinesystem

instance and updatable seem to be required in the API docs, but the main doc and PG example imply they're optional.

I'm using same version of BJS as PG so not sure why my TS version of the code is failing.

I removed updatable and it works

Hi @jerome

I probably wasn't clear. The original PG worked fine. It's only when I try to do the same in my TypeScript code that I get that error. Plus the API docs seem to indicate that instance and updatable are required.

Same issue with BABYLON.MeshBuilder.CreateLines("lines", {points: myPoints}, scene);

Using BJS v3.2.0-beta.4 with corresponding babylon.d.ts but VS Code tsc is showing error:

error TS2345: Argument of type '{ points: any[]; }' is not assignable to parameter of type '{ points: Vector3[]; updatable: boolean; instance: LinesMesh; colors?: Color4[]; useVertexAlpha?:...'.
  Property 'updatable' is missing in type '{ points: any[]; }'

It's not failing to compile, it's only saying there's an error. It'll run just fine.

@Gijs thanks, I'll try it again, but it's still an issue if it's displaying like that in the IDE and the documentation is ambiguous, right?

In the interim I ended up using a series of:

BABYLON.Mesh.CreateLines("lines", points, scene);

And this worked fine.
