With Typescript 4.9.4 target ES2020 and BJS 5.39.0, I am getting TypeScript Compile errors:
Any suggestions?

Hello! Can you share more about your project configuration? How’s the package.json and the typescript configs? @Cedric is out at this moment :christmas_tree: but he’ll see this as soon as he’s available :slight_smile:

3

setting the tsconfig option to skipLibCheck=true fixes this.

I also found this issue after I install the package. The setup uses Angular 15. Here is the package.json setting.

Once Cedric and Raanan are back they’ll look into it :smiley:

@RaananW will have a look soon. I think we might need to update our TS version :slight_smile:

i’m on it! it’s a UMD issue only. moving to @babylonjs/core instead will prevent this issue, BUT of course we support UMD as well :slight_smile:

Hi @RaananW is this one fixed yet?

This should have been resolve by now. If it wasn’t please let me know.

TS2345: Argument of type ‘AbstractMesh’ is not assignable to parameter of type ‘Mesh | AbstractMesh’.
Type ‘AbstractMesh’ is missing the following properties from type ‘AbstractMesh’: _physicsBody, physicsBody, getPhysicsBody

So how can I solve this problem

Hello and welcome!

(m as Mesh)
or better

if (m instanceof Mesh) {
// do something
}
