smooth movement
Well I finished scripting my core movement script but the problem is the movement is not smooth. How can i make it more smoother? Player can jump for infinite times, I tried to disable it with yield but it still doesnt work. Player can jump rapidly if the player press space button rapidly. Its like infinite jump. How can i disable that too?
#pragma strict
var speed : float = 2;
var jumpForce : float = 20;
function Update ()
{
if (Input.GetKeyDown("w"))
{
this.transform.position.x += this.speed;
}
if (Input.GetKeyDown("a"))
{
this.transform.position.z += this.speed;
}
if (Input.GetKeyDown("s"))
{
this.transform.position.x -= this.speed;
}
if (Input.GetKeyDown("d"))
{
this.transform.position.z -= this.speed;
}
if ( Input.GetKeyDown("space") )
{
Jump();
}
}
function Jump()
{
yield WaitForSeconds(2);
rigidbody.AddForce (Vector3.up *jumpForce);
}
Try 'this.speed * Time.deltaTime; '
Also, not sure weather you have some other purpose for doing so, but you don't need to define 'this' for just using variables and transforms.
transform.position.z -= speed * Time.deltaTime;
should work just fine.
With your jump problem, your might be better off using a raycast - basically a line from your object that will collide with things, and you can set it's length.
http://docs.unity3d.com/ScriptReference/Physics.Raycast.html
So if the line isn't touching the floor, don't jump, else if it is touching the floor, jump.
e.g. Untested code, there may be spelling mistakes
RaycastHit hit;
if(Physics.Raycast(transform.position, Vector3.down, out hit, 1.5f)){
Jump();
}
If raycasts are a new concept, they can be confusing to understand (personally anyway)you can do this: To visibly see the ray you'll be casting.
Debug.drawLine(transform.position, Vector3.down, color.black, 1.5f);
If you're using a rigidbody for your character, place any physics code inside FixedUpdate(). I'd also use forces / velocity rather than position iteration. You would also want to use rigidbody.position or rigidbody.movePosition if you prefer using positions rather than forces, again, in FixedUpdate. Have a look at RigidbodyFPSWalker on the wiki.
try-
#pragma strict
var speed : float = 2;
var jumpForce : float = 20;
function Update ()
{
if (Input.GetKeyDown("w"))
{
this.transform.position.x += this.speed*Time.deltaTime;
}
if (Input.GetKeyDown("a"))
{
this.transform.position.z += this.speed*Time.deltaTime;
}
if (Input.GetKeyDown("s"))
{
this.transform.position.x -= this.speed*Time.deltaTime;
}
if (Input.GetKeyDown("d"))
{
this.transform.position.z -= this.speed*Time.deltaTime;
}
if ( Input.GetKeyDown("space") )
{
Jump();
}
}
function Jump()
{
yield WaitForSeconds(2);
rigidbody.AddForce (Vector3.up *jumpForce*Time.deltaTime);
}
