Clamp Y with Rigidbody character using addforce (drone)

Unity Engine
1

Hi All,
Im struggling with clamping my character to the camera bounds. For some reason when the character reaches the clamp it begins to jitter. I have tried different force methods, clamp positions vs velocity but I really do need some help as I am not a very experienced coder.

The project is a side scroller using 3d meshes and the character needs to feel like a drone which is why I am using addforce instead of position.

transform.position = new Vector3(transform.position.x, Mathf.Clamp(transform.position.y, -2f, 5.1f), transform.position.z);

//input region for managing the movement of the character
//Upwards movement
if (Input.GetAxis(“Vertical”) > 0.0f)
{
//rigidbodyCharacter.AddForce(0, Upwardthrust, 0, ForceMode.Acceleration);
rigidbodyCharacter.AddForce(0, Upwardthrust, 0, ForceMode.Force);
}

Any ideas?

Do you use Update() or FixedUpdate()?

FixedUpdate()

Fixed it by removing the forcemode and reducing the parameters to the minimum required.

rigidbodyCharacter.AddForce(Vector3.up * Upwardthrust);
