solved [solved] Uncaught TypeError assigning Material to Mesh

[Rook]

I have a very basic setup, and it works in a Playground, but throws this error when I am running it in an Electron app (still very basic).  I have [email protected] saved as an npm dependency.

I have a Module that contains a class.  

Quote

var BABYLON = require('babylonjs')

 

class Star {

constructor (scene, starData) {

 

this.id = starData.id

this.name = starData.name

this.spectralColor = new BABYLON.Color3(1.0, 0.0, 0.0)

this.absmag = starData.absmag

 

// Create the mesh

var mesh = new BABYLON.MeshBuilder.CreateSphere(starData.name, { 'diameter': 1.0 }, scene)

 

// Load star texture files

var material = new BABYLON.StandardMaterial('mat', scene)

material.diffuseColor = new BABYLON.Color3(1, 0, 0)

// material.emissiveColor = new BABYLON.Color3(1.0, 0.0, 0.0)

// material.specularColor = new BABYLON.Color3(1.0, 0.0, 0.0)

// material.ambientColor = new BABYLON.Color3(1.0, 0.0, 0.0)

mesh.material = material

.

When the last line is commented out, this runs just fine, no errors.

When material assignment is un-commented, it throws the following error in the console of Chrome:

I think that this is very basic and simple code, and cannot figure out why this is throwing a Uncaught TypeError.

Rolled back from version 3.1.0-alpha2 to 3.0.7 and the problem goes away.

This seems to be a bug in the latest version.

Logged bug.

Can you repro in the PG?

[Rook]

I cannot choose a version number in the Playground, only 'Stable' vs 'Latest'.  

For me, when I 'npm remove babylonjs' and then 'npm install --save [email protected]' and then the code worked, it seems like a version bug in the Alpha.  I could be wrong?

[GameMonetize]

The latest NPM version is the same as the playground in latest mode.

 

Perhaps you can share a web page that highlights the issue?
