Why does my Animals fly?

I have bought an asset in the asset store which worked great till Unity 4.6 But since I changed to 5 my animals start to float over the ground after some seconds and then after a while even rotating around the y axis. I wrote the developer but so far I got no answer since a longer time. So I guess I have to fix that by myself but I don't see the problem. The animal has a character controler, an animation and a FSM.

The problem seems to starts when the animal changed from the idle state to the moving state. In Unity 4.6 everything was fine

Code (CSharp):

1. public class FSM : MonoBehaviour {
2.     public float gravity = 100.0f;//gravity affecting character
3.     private enum State {//enumeration of states
4.         Idle,//idling state
5.         Search,//searching state
6.         BackHome,
7.     }  
8.     private float speed = 6.0f;//character's movement speed
9.     private float timer = 1f;//time we're going to spend searching player
10.     private float timeCheck;//
11.     private float idlingTime = 5f;//time we're going to spend for idling
12.     public float idleTimeReset = 5f;//idling time reseter
13.     private bool alive= true;//cow is still alive
14.     private bool idling;
15.     public bool iamACow;
16.  
17.  
18.     private State state;
19.     private CharacterController charContrl;//character controller
20.     private Vector3 target;//coordinates of the target
21.     private Vector3 homePosition;
22.     private Vector3 moveDirection;//movement direction
23.     private Vector3 lookDirection;//look direction
24.  
25.     // Use this for initialization
26.     void Awake()
27.     {
28.         homePosition = this.transform.position;

39.         state = FSM.State.Search;//starting state set to idle
40.         StartCoroutine("FSMach");//start our state machine
41.                
42.     }
43.     private IEnumerator FSMach(){
44.         while(alive){//if character is still alive
45.             switch(state){
46.                 case State.Search:
47.                     Search();
48.                     break;

you are using Animator Component on the Animals.

Check if Apply Root Motion is checked if yes, disable it.

 

Where can I find that? I looked in the inspector and only the dog has an animator component in it. There is a root motion option. All other animals have only an animation and there I can't see that option. Can I find it somewhere else?

 

I looked for this root motion and found something. It's disabled. When I enabled root motion then I could see that the movement looks much different from my problem, so I guess the reason is somewhere else. I made a small video to show how my "floating" looks like. It seems as if the animals are stepping on some invisible rock or stair. I can't find a reason.

The Animationtype is legacy and Generation is "Store in Root (new)"

 

I changed .Move to .SimpleMove and now my animals stay on the ground. But I don't understand why .Move isn't working. In Unity 4.6 it was no problem

 

CharacterController.SimpleMove
public bool SimpleMove(Vector3 speed);

Description
Moves the character with speed.

Velocity along the y-axis is ignored.


try commenting line 111 (disable it) and run .Move()

Code (CSharp):

1. moveDirection.y -= gravity * Time.deltaTime*10f;// applying gravity

Code (CSharp):

1. // moveDirection.y -= gravity * Time.deltaTime*10f;// applying gravity

 

Thank you this makes them stay down but I don't understand why.
