How to Completely Dispose a mesh on collision detection?

[Abdullah]

How to dispose a material on run time and dynamically create again. I want when my sphere material collide with floor material my sphere material should dispose completely and I want to create a new sphere material again.

To dispose a mesh

sphere.dispose();

For create sphere

var sphere = BABYLON.Mesh.CreateSphere("sphere", 16, 2, scene);

Use sphere.intersectsMesh(ground, false) for to detect the collision with the ground

Exemple :

var ground = BABYLON.Mesh.CreateGround("ground1", 6, 6, 2, scene);
var sphere = BABYLON.Mesh.CreateSphere("sphere", 16, 2, scene);

if(sphere.intersectsMesh(ground, false))
{
    sphere.dispose(); // dispose sphere
    sphere = BABYLON.Mesh.CreateSphere("sphere", 16, 2, scene);// create again sphere
}

Yep, well said, @Dad72. 

And for materials, there is also a dispose(). 

But I THINK (speculate)... that if you create a replacement material, and then set mesh.material = replacementMaterial... that will replace the previous material. 

Then, I think the JS garbage collection (GC) system... will dispose the old material for you. 

(Clear ALL variables and properties of "references-to" the old material... when you are finished using it.) 

Not sure about the GC situation, though.  Test/read to verify.  Hope this helps.

If possible, it would be more efficient to hide the sphere material and reuse it.

I think there is a difference between the title and the content of the thread.

I think he means only the material, although the title says otherwise.

So in @Dad72's example, instead of creating a new sphere, create a new material and either dispose the old one, or let the GC do the job (Something I have absolutely No knowledge of).

Would saying oldmaterial = ""; be enough, assuming you don't have other references to the material?

Pretty!    Good grinding code... yet tootie frootie.  heh

Yeah, @Abdullah, did you mean "mesh" like in the thread title, or "material" like in the post?  Can you fix one of them... for us?  thx! 

[Abdullah]

Thank you all for replying, My bad I meant "material", I want to dynamically dispose material and re create it whenever i detect collision
