runCoroutineAsync doesn't exist if I import Scene from '@babylonjs/core/scene'

I’m trying to reduce my bundle size by importing only from absolute imports and none from ‘@babylonjs/core’.
So I’m importing Scene from ‘@babylonjs/core/scene’.

However, now I’m getting an error;

TypeError: scene.onBeforeRenderObservable.runCoroutineAsync is not a function

Everything works if I import Scene from ‘@babylonjs/core’ but that increases the bundle size almost by 2x.


its here. Babylon.js/observableCoroutine.ts at master · BabylonJS/Babylon.js · GitHub

i think the question is, do you want buggy code or 2x size bundle? without question i take the 2x bundle size.

I ultimately agree with you. It’s not my bottleneck anyways. Just got over-focused on optimizing I guess.
Thanks :+1:

You could

import "@babylonjs/core/misc/observableCoroutine";

to ensure the side effects would “augment” your scene capabilities with the coroutines addition so growing a tiny bit the code with only the features you need.
