I am making a 2D game I want my 2D character to jump when button is pressed it works but it
also lags for a few seconds in the air.
Here's my code
#pragma strict
//For lerping
var newPosition : Vector3 = Vector3.zero;
var MoveDirection : Vector3 = Vector3.zero;
var smooth = 2.0;
var moveSpeed : float = 8;
var jumpSpeed : float = 25;
var fallSpeed : float = 64;
var maxFallSpeed : float = 60;
var maxUpSpeed : float = 25;
var slopeLimit : float = 45;
var dashSpeed : float = 120;
var fly : boolean;
private var vm : float;
var onGround : boolean;
private var xScale : float;
private var h : float;
private var v : float;
private var jump : boolean;
private var anim : Animator;
private var circCollider : CircleCollider2D; //If boxCollider2D is used replace w/ ... private var boxColl : BoxCollider2D;
function Awake ()
{
newPosition = transform.position;
}
function Start ()
{
xScale = transform.localScale.x; //Get correct starting Orientation for player.
anim = gameObject.GetComponent("Animator"); //Get Animations for character
circCollider = GetComponent(CircleCollider2D); //if boxCollider2D is used replace w/... boxColl = GetComponent(BoxCollider2D);
}
function Update ()
{
//h = Input.GetAxisRaw("Horizontal"); //get horizontal input
//v = Input.GetAxisRaw("Vertical"); //get vertical input
jump = Input.GetKey(KeyCode.Space); //get jump input
//calls the lerp funtion
LerpChanging ();
}
function FixedUpdate()
{
if(onGround && jump)//Are we grounded can we jump?
{
vm = jumpSpeed;
}
var moveH : float = h * moveSpeed * Time.deltaTime; //Smooth horizontal movement
//Flip character orientation
// if(h < 0){
// transform.localScale.x = -xScale;
//} else if(h > 0){
// transform.localScale.x = xScale;
//}
anim.SetFloat("VM", vm); //Animate VM parameter
anim.SetBool("Grounded", onGround); //Animate Grounded parameter
rigidbody2D.AddForce(Vector2.right * moveH); //Apply horizontal movement
rigidbody2D.AddForce(Vector2.up * vm); //Apply vertical movement
if(fly)
{
//Can we fly?
if(v > 0)
{
//Fly like a bird!!!
vm += v * Time.deltaTime * 20;
}
else
{
//Uh oh it's gravity
vm -= fallSpeed * Time.deltaTime;
}
}
else
{
//Gravity ... ouch!
vm -= fallSpeed * Time.deltaTime;
}
vm = Mathf.Clamp(vm, -maxFallSpeed, maxUpSpeed); //Clamp vertical speeds
rigidbody2D.velocity = Vector2.zero; //Stop movement if there is no input
onGround = false; //Clear out grounding check
}
function OnCollisionEnter2D(c : Collision2D)
{
CheckCollision(c);
}
function OnCollisionStay2D(c : Collision2D)
{
CheckCollision(c);
}
function CheckCollision(c : Collision2D)
{
for(var contact in c.contacts)
{
//Check for floor hit
//If boxCollider2D is used replace circCollider.radius w/ (boxCollider2D.size.y/2)
if(vm <= 0 && contact.point.y <= transform.position.y - circCollider.radius && Vector2.Angle(Vector2.up, contact.normal) <= slopeLimit)
{
onGround = true;
vm = Mathf.Max(0, vm);
}
}
}
function LerpChanging ()
{
//variable for the lane system
var positionA : Vector3 = new Vector3(-47, -6, -10);
var positionB : Vector3 = new Vector3(-47, -12, -10);
//move the character in 4 lane
if(Input.GetKeyDown(KeyCode.Q))
{
newPosition = positionA;
}
if(Input.GetKeyDown(KeyCode.E))
{
newPosition = positionB;
}
transform.position = Vector3.Lerp(transform.position, newPosition, Time.deltaTime * smooth);
}
