BABYLON.MeshBuilder.CreateLines throws Uncaught TypeError

Recommended Posts

Hi guys,

I'm having troubles drawing some lines out of a Vector3 array with MeshBuilder.CreateLines / Mesh.CreateLines..

I've seen many examples of drawing lines in various playgrounds

e.g. http://www.babylonjs-playground.com/#1DKDYG#0 - http://www.babylonjs-playground.com/#RF9W9

However, when I try to use these examples in my environment I get the following error:

Uncaught TypeError: Cannot set property isPickable of #<i> which has only a getter
i @ babylon.2.3.js:5
r @ babylon.2.3.js:10
i @ babylon.2.3.js:18
createScene @ LineScene.js:93 <- my awesome babylon scene :P

 

I was not able to reproduce this error in the playground, the part of my code which causes the error:

..
           
// shape
var shape = [
    new BABYLON.Vector3(1, 0, 0),
    new BABYLON.Vector3(0.2, 0.3, 0),
    new BABYLON.Vector3(0, 1, 0),
    new BABYLON.Vector3(-0.2, 0.3, 0),
    new BABYLON.Vector3(-1, 0, 0),
    new BABYLON.Vector3(-0.2, -0.3, 0),
    new BABYLON.Vector3(0, -1, 0),
    new BABYLON.Vector3(0.2, -0.3, 0),
    ];
shape.push(shape[0]);
                
//this doesn't work
var shapeline = BABYLON.MeshBuilder.CreateLines("sl", {points: shape}, scene);
                
//neither does this
//var shapeline = BABYLON.Mesh.CreateLines("sl", shape, scene);

..

The rest of the code is only the creation of a simple scene from the very basic Babylon getting started tutorial and is working fine when I remove the CreateLines.

Any ideas what I'm doing wrong?

Cheers,

Lesterhaus

Thanks Deltakosh, switching to 2.4 fixed this issue! 

I feel stupid for not trying to switch to 2.4 myself - In the documentation I only found 2.3 classes which also included the MeshBuilder class and the CreateLines method so I guess I was too panicked to calmly check other sources for this.

 

Anyways, thanks a lot!
