Combining Children into 1 Mesh + Collider

[Hilm]

Hey,
So I’m trying to combine the child objects of an empty parent game object into 1 mesh, then apply a mesh collider.

I’m using the code below… The issue is that on line “var meshFilters : MeshFilter[ ] = GetComponentsInChildren(MeshFilter);” it springs up an error at runtime saying:

“InvalidCastException: Cannot cast from source type to destination type.
CombineMesh.Start () (at Assets/GameScripts/CombineMesh.js:17)”

Can anyone see something I’m doing wrong? I’m building for iOS*

Thanks in advance!

function Start ()
{

gameObject.AddComponent(MeshFilter);
gameObject.AddComponent(MeshRenderer);
gameObject.AddComponent(MeshCollider);

for (var child : Transform in transform){
child.position += transform.position;
}
transform.position = Vector3.zero;
transform.rotation = Quaternion.identity;

var meshFilters : MeshFilter[ ] = GetComponentsInChildren(MeshFilter);
var combine : CombineInstance[ ] = new CombineInstance[meshFilters.Length-1];
var index = 0;

for (var i = 0; i < meshFilters.Length; i++){
if (meshFilters*.sharedMesh == null) continue;*
_ combine[index].mesh = meshFilters*.sharedMesh;_
_ combine[index++].transform = meshFilters.transform.localToWorldMatrix;
meshFilters.renderer.enabled = false;
}
GetComponent(MeshFilter).mesh = new Mesh();
GetComponent(MeshFilter).mesh.CombineMeshes (combine);
GetComponent(MeshCollider).sharedMesh = GetComponent(MeshFilter).mesh;
renderer.material = meshFilters[1].renderer.sharedMaterial;*_

* Destroy(gameObject.collider);*
* gameObject.AddComponent(“MeshCollider”);*
* GetComponent(MeshCollider).sharedMesh = GetComponent(MeshFilter).mesh;*
