Hello!
I’m new Unity and am trying to create a 2.5D infinite runner that has a jump and a dash. I’ve been trying different methods of getting the character to move and not sure how to proceed as I have 2 problems with the character dash.
-
If I use rigidbody.addforce my character dash works perfectly fine, but it takes way to long for the character to get up to the desired top speed when starting off from a standstill.
-
If I use rigidbody.velocity (the method I think I want to go with) using the same script to dash it does not increase the players speed.
Any help will be much appreciated

public bool onGround;
public float jumpForce;

private Rigidbody theRB;
private GameManager GMS;
// Use this for initialization
void Start () {
GMS = GameObject.Find ("Canvas").GetComponent<GameManager> ();
onGround = true;
theRB = GetComponent<Rigidbody> ();
}
// Update is called once per frame
void Update ()
{
if (GMS.countDownDone == true) {
//theRB.AddForce (Vector2.right * moveForce);
theRB.velocity = new Vector2 (moveForce, theRB.velocity.y);
if (Input.GetButtonDown ("Jump") && onGround) {
if (jumpForce > 0f) {
//theRB.AddForce (Vector2.up * jumpForce, ForceMode.Impulse);
theRB.velocity = new Vector2 (theRB.velocity.x, jumpForce);
onGround = false;
}
}
}
