Gravity slower when moving Rigidbody.

[stevexu]

I have a tk2dSprit with a Rigidbody  attach to it,
When I move a Rigidbody using this script:

Code: [Select]

if (Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.RightArrow))
        {
            moveTowardRight();
        }

  void moveTowardRight()
   {
       cleanFlag(STATE_STANDBY);
       cleanFlag(STATE_RUN_LEFT);

       addFlag(STATE_RUN_RIGHT);

       Vector3 vy = rigidbody.velocity.y * (hasFlag(STATE_JUMP) ? Vector3.up : Vector3.zero);

       rigidbody.velocity = vy + Vector3.right * SPEED;
   }


it does go forward but has a decreased gravity, so it looks like it floats but when I release the key that makes my rigidbody move it drops down way faster. All the settings of my rigidbody are default so why does this happen ??

Don't know, but where are you calling moveTowardRight from?

In FixedUpdate.

 I checked, the  rigidbody.velocity .y  is  always 0 , and  the   Physics.gravity  is always -9.8,  and nobody collid with rigidbody

Code: [Select]

    void FixedUpdate()
    {
      //  rigidbody.WakeUp();
        detectKey();
        updateAniByState();

        System.Diagnostics.Debug.Assert(rigidbody.position.z == -0.5);

        print("rigidbody.velocity  = " + rigidbody.velocity + " rbody = " + rigidbody);
    }




    void detectKey()
    {
       
        if (Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.RightArrow))
        {
            moveTowardRight();
        }
        else if (Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.LeftArrow))
        {
            // rigidbody.transform.Translate(Vector3.left * SPEED * Time.deltaTime);
            moveTowardLeft();
        }

I'm not sure what else to suggest - I've not tried this before.
