# Smooth "Flappybird"

Hello, i wanna do something like Flappybird,just with an Airplane.When i keep pressing its keep going up,everything fine, but its going up with “steps” just like it would go up an stair.How can i make,that its going up smooth?And how can i make an white line behind the players way?Just like an path wich the players flew.My idea is the game “Sky glider”

using UnityEngine;
using System.Collections;

public class Playermovement : MonoBehaviour {

``````Vector3 velocity = Vector3.zero;
public Vector3 gravity;
public Vector3 flapVelocity;
public float maxSpeed = 5f;
public float fixedvelocity = 1f;

bool didFlap = false;

// Use this for initialization
void Start () {

}

void Update() {

if (Input.GetKey(KeyCode.Space) || Input.GetMouseButton(0) ) {

didFlap = true;

}

}

// Update is called once per frame
void FixedUpdate () {

velocity.x = fixedvelocity;
velocity += gravity * Time.deltaTime;

if (didFlap == true) {

didFlap = false;

if(velocity.y <0)
velocity += flapVelocity;

}

velocity = Vector3.ClampMagnitude (velocity, maxSpeed);

transform.position += velocity * Time.deltaTime;

}
``````

velocity = Vector3.ClampMagnitude (velocity, maxSpeed);

I think you have a big problem here. If velocity>maxSpeed then they’ll modify it’s x direction to. so why don’t you:

`````` velocity = Vector3.Min (velocity, maxSpeed);
``````

And make sure `maxSpeed` is always more than `flagVelocity`

PS: May bit off topic. But I think when it’s flagged it should be `velocity = flapVelocity;`
