Decrease a value over time when W is pressed.
Hey, what I am trying to achieve is this:
When the user presses the W key, I want the fuel variable to deduct by 10 every 5 seconds. I have written a little script but unfortunately for me, I'm only learning at the moment and can't seem to suss it out :P Here is my script:
var speed : float = 3.0;
var rotateSpeed : float = 3.0;
var bulletPrefab:Transform;
var shotDelay = 2;
var status1 = "Loaded";
var style : GUIStyle;
var fuel : float = 100.0;
var fuelDeduct = 2.0;
function Start () {
while (true) {
while (!Input.GetButtonDown("Jump")) yield;
bullet = Instantiate(bulletPrefab, GameObject.Find("SpawnPoint").transform.position, transform.rotation);
bullet.tag = "bulletShot";
status1 = "Reloading";
bullet.rigidbody.AddForce(transform.forward * 5000);
yield WaitForSeconds(shotDelay);
status1 = "Loaded";
}
}
function Update ()
{
var controller : CharacterController = GetComponent(CharacterController);
transform.Rotate(0, Input.GetAxis ("Horizontal") * rotateSpeed, 0);
var forward : Vector3 = transform.TransformDirection(Vector3.forward); var curSpeed : float = speed * Input.GetAxis ("Vertical");
controller.SimpleMove(forward * curSpeed);
}
@script RequireComponent(CharacterController)
if(Input.GetKey("w"))
{
fuel -= fuelDeduct * Time.deltaTime;
}
function OnGUI()
{
GUI.Label(Rect(250, 70, 100, 20), status1, style);
GUI.Label(Rect(250, 120, 100, 20), fuel.ToString("f0"), style);
}
Basically I wish for the fuel variable to deduct by 5 every 10 seconds but so far nothing is happening. Can anyone point me in the right direction? :) Try not to spoon feed me please, I like learning the hard way :)
"You can't use yield from within Update or FixedUpdate, but you can use StartCoroutine to start a function that can."
I am just doing it in baby steps at the moment, I like to know everything I am writting. I have written this:
function Update () {
while (Input.Get$$anonymous$$eyDown ("1")){
Debug.Log "hello"; } }
Why does that not return hello in the log?
Try something like this:
var style : GUIStyle;
var fuel : float = 100.0;
var fuelDeduct = 2.0; // reduce 2 each second == 10 every 5 sec
function Update ()
{
if(Input.GetKey("w"))
{
fuel -= fuelDeduct * Time.deltaTime;
}
}
function OnGUI()
{
GUI.Label(Rect(250, 120, 100, 20), fuel.ToString("f0"), style);
}
This will continously reduce the fuel while the button is held down. This is way better than reducing it in big intervals.
Thanks for the reply, I implemented your method but the variable does not decrease, could you point me in the right direction please? I will update the code.
You've got Bunny's if statement in the wrong place. It needs to be inside the Update $$anonymous$$ethod.
Cheers $$anonymous$$ark, silly me :P Learning every day! Thank you very much also Bunny! Exactly what I needed :)
Is one of the rewrites a removal of a loop in Start()? Because otherwise it's never going to check for getkeyDown after the first check.
Keep in mind that the loop must reach a yield statement even if the player doesn't hit a key.
