problem with dispose

[dav74]

Hi,

In the beginning i've a plan and a sphere in a scene. The whole scene disappears after a "sphere.dispose()"

scene.registerBeforeRender(function(){	if (time>0 && flag==1){		if (sphere. intersectsMesh(plan,true)==false){			sphere.position.y=30-0.5*2*Math.pow(time,2);		}		else {			window.setTimeout(function(){				sphere.dispose();				flag=0;			},2000)		}	}	time=time+(1/BABYLON.Tools.GetFps());}); 

thank you for your help

It could be related to setTimeout which can update the list of meshes during a render

 

Could you try with scene._toBeDisposed.push(sphere) ?

thank you for your answer

i replaced  sphere.dispose() by scene._toBeDisposed.push(sphere) but nothing change, all my scene disappears after the 2 seconds (not only the sphere)

Could you share a jsfiddle with your bug?

it's done : http://jsfiddle.net/dav74130/N8ZR6/

Your jsfiddle seems incomplete (no html and no external reference to babylon.js)

I made it work like this : 

scene.registerBeforeRender(function(){    if (time>0 && flag==1){        if (sphere. intersectsMesh(plan,true)==false){           sphere.position.y=30-0.5*2*Math.pow(time,2);    }    else {        window.setTimeout(function(){           if (scene.getMeshByName("sph")){              sphere.dispose();             flag=0;           }        },2000)   }}time=time+(1/BABYLON.Tools.GetFps());}); 

I think the problem comes from the dispose function that is called several times with the same object. 

 

Here are the lines in the Mesh.dispose() method :

var index = this._scene.meshes.indexOf(this);

=> returns -1 if the object does not exists (the method is called several times on the same object), and :

this._scene.meshes.splice(index, 1);

with index = -1 removes the last element of the array (the plane )

this should work too:

window.setTimeout(function(){
 if (scene.getMeshByName("sph")){
  sphere.dispose();
}
},2000)

flag=0; // Moving flag out of timeout function
