Problem to play animation in C#

I got this error message: $$anonymous$$issingComponentException: There is no 'Animation' attached to the "Gearing(Clone)" game object, but a script is trying to access it. You probably need to add a Animation to the game object "Gearing(Clone)". Or your script needs to check if the component is attached before using it. UnityEngine.Animation.Play (System.String animation) (at C:/BuildAgent/work/842f9557127e852/Runtime/ExportGenerated/Editor/Animations.cs:411) Jeu.InitTableauJeu () (at Assets/Scripts/Jeu.cs:132) Jeu.Start () (at Assets/Scripts/Jeu.cs:36)

you need to add animation components to objects that you want to animate .... to do that just select the object that you want to add an animation component to in the hierarchy view ... then go to the menu Component->$$anonymous$$iscellaneous->Animation .... make sure it's "Animation" and not "Animator" ... then in the inspector view you can set the size of the animation list and add animations to your object

But in my case that didn't work because my gameObject is created in my script like that: objArrayGame[i,j] = Instantiate(tGearing.gameObject, vector, Quaternion.identity) as GameObject; tGearing is type tramform. And is not created before start the program.

Anime$$anonymous$$uNyo, you can use AddComponent() in order to add an animation component to the newly instantiated GameObject.

I tried that before but I got an error, which says me that the component doesn't exist. It's possible I put a wrong thing in the function parameters, i do that: objArrayGame [i,j].AddComponent("Gearing");

tGering is the prefab named Gearing who got 3 GameObject (bloc, stem, and gearing). gearing got the animation "RotateGearing" attach on him.

This is my script, I got the error message $$anonymous$$issingComponentException(description in my second post)in the second instruction in my case 2:

public class Game : $$anonymous$$onoBehaviour {

public Transform tWall;

public Transform tBloc;

public Transform tGearing;

private GameObject [,]objArrayGame = new GameObject[6,6];

private int [,]iArrayGame = new int[6,6] {{0,0,0,0,0,0}, {2,4,1,1,2,0}, {0,5,4,4,1,0}, {0,1,4,4,1,0}, {0,4,1,1,4,3}, {0,0,0,0,0,0}};

private Object obj;

private Vector3 vector = new Vector3(0.5f, 0.5f, 0.5f);

void Start () {

InitArrayGame();

}

void InitArrayGame ()

{

for (int i = 0; i< 6 ; ++i) {

for (int j = 0; j< 6 ; ++j) { vector.x = j+0.5f; vector.z = i+0.5f;

switch (iArrayGame [i,j]) {

case 0: objArrayGame [i,j] = Instantiate(tWall.gameObject,vector,Quaternion.identity) as GameObject; break;

case 1:
objArrayGame [i,j]= Instantiate(tBloc.gameObject,vector,Quaternion.identity) as GameObject; break;

case 2:
objArrayGame [i,j] = Instantiate(tEngrenage.gameObject,vector,Quaternion.identity) as GameObject;

objArrayGame [i,j].animation.Play("RotateGearing"); break;

case 3:
objArrayGame [i,j] =Instantiate(tGearing.gameObject,vector,Quaternion.identity) as GameObject; break;

case 4:
objArrayGame [i,j] = Instantiate(tGearing.gameObject,vector,Quaternion.identity) as GameObject; break;

default: objArrayGame [i,j] = null; break; } } } } }

That's what I've been saying. If you're going to call an animation on something, it must have an Animation component and an AnimationClip in order to play. Trace through your code and find out where you're calling ".animation.Play(", then make sure that ".animation" isn't null.
