javascript object creation and "n is undefined"

[esnho]

Hello,

I'm tryng to create an object wich holds mine ground in a scene, I'm using this code but it doesn't works, in console I receive a "n is undefined" message.
But with the vector creation, for example, there's no problems....

 

var terreno = {	    noiseTexture : "media/noise2.jpg",    distortAmount : 10,    offset : -20,	    xmin : -200,    zmin : -200,    xmax :  200,    zmax :  200,    precision : {        "w" : 80,        "h" : 80    },    subdivisions : {        'h' : 1,        'w' : 1    },    // Create the Tiled Ground    create : new function(name, scene) { //"Tiled Ground"    	this.scene = scene;    	this.name = name;    	    	this.v = new BABYLON.Vector3(1, 10, 0);    	this.tiledGround = new BABYLON.Mesh.CreateTiledGround(name, this.xmin, this.zmin, this.xmax, this.zmax, this.subdivisions, this.precision, scene);    	    }        };

mmh....

I guess "new function(name, scene)" creates a new JS object, so the keyword this used inside this function could not refer to the upper object terreno.

Did you display with console.log() what were the values of this.xmin, this.subdivsions, etc just before calling CreateTiledGround() ?

 

It just looks like a classic javascript "this" scope issue.

I think this should fix your problem as suggests Jerome :

var that = this;precision : {......// Create the Tiled Groundcreate : function(name, scene) { //"Tiled Ground"    	that.scene = scene;    	that.name = name;    	    	that.v = new BABYLON.Vector3(1, 10, 0);    	that.tiledGround = new BABYLON.Mesh.CreateTiledGround(name, that.xmin, that.zmin, that.xmax, that.zmax, that.subdivisions, that.precision, that.scene);    	}

I fixed changing the function declaration:
 

create : function(name, scene)

Thank you jerome
