Question Character never touches ground

Hi I have the following code to handle jump:

Code (CSharp):

1.  
2. //I check state is in the enter state and calculate the vertical velocity to push the player
3.             if (_isGrounded && _velocity.y == 0)
4.             {
5.                 _velocity.y += Mathf.Sqrt(_jumpHeight * -2.0f * _gravity);
6.             }
7.  
8.             //Add gravity
9.             _velocity.y += _gravity * Time.deltaTime;
10.             //Add vertical drag
11.             _velocity.y /= 1 + _drag * Time.deltaTime;
12.             //move the player
13.             _controller.Move(_velocity * Time.deltaTime);
14.  
15.  
16.             //to stop the velocity from falling
17.             //Velocity starts becoming negative at the top of the jump, so I reset it when the player is grounded
18.             if (_isGrounded && _velocity.y < 0)
19.             {
20.                 _velocity.y = 0f;
21.             }
22.  

It works fine, but the player never touches ground, floating over the terrain, even if velocity value = -1.23f and _isGrounded = False;



Any clues?
I'm using CharacterConroller and a UMA character.

 

Ok, if I change the charcter's controller colider position, it works, but now the collider covers only the upper half of the body...

 

Check the skin width on the character controller....

Unity - Manual: Character Controller component reference (unity3d.com)

You could also make the model a child of the object that carries the CharacterController, then adjust the models position for a more fine tuned output...

ALSO - I think a CharacterController should have a small downward force applied even when grounded to keep it's own inner Grounded state set to true.
