C# Array of OtherArray's Meshes

Question

Hi everyone, I've been trying to create an Array of SomeTransformArray's Meshes. I'm getting an error from the console saying Transform[] doesn't contain a definition of GetComponent. What is wrong with my code?

     public Transform[] someTransformArray;
     public Mesh[] someTransformArrayMeshes;
 
     void Awake(){
 
         someTransformArray = GetComponentsInChildren<Transform>();
         
     for (int a = 0; a < someTransformArray.Length; a++)
     someTransformArrayMeshes = someTransformArray.GetComponent<MeshFilter>().sharedMesh[a];
 
 }

someTransformArrayMeshes and someTransformArray are both declared as arrays, which as the error message says do not contain a definition for GetComponent, and in any case you should specify the particular object you want to access in the array. So you should change your line 9 to something like:

 someTransformArrayMeshes[a] = someTransformArray[a].GetComponent<MeshFilter>().sharedMesh;

I'm getting a null reference exception from the console. It says the error is coming from line 9 but I don't understand why.

  public Transform[] someTransformArray;
 public Mesh[] someTransformArrayMeshes;
  
 void Awake(){
  
 someTransformArray = GetComponentsInChildren<Transform>();
  
 for (int a = 0; a < someTransformArray.Length; a++)
 someTransformArrayMeshes = someTransformArrayMeshes[a] = someTransformArray[a].GetComponent<MeshFilter>().sharedMesh;
  
 }

I tried using the same method that I used for my someTransformArray and it worked.

 public MeshFilter[] someTransformArrayMeshes;
 
 void Awake(){
 someTransformArray = GetComponentsInChildren<MeshFilter>();
 }

Try replacing your line 9 with the exact line I gave you, your version still has some unnecessary extra that's probably causing the errors.

What you're doing there is assigning a single object from the array as the entire array - that makes no sense. I think you might need to revise how arrays work, try for example http://en.wikibooks.org/wiki/Data_Structures/Arrays and http://msdn.microsoft.com/en-us/library/aa288453(v=vs.71).aspx
