Delay A Function Via Time

[TheEmeralDreamer]

I have a function that I would like to limit the use of via two variables
`

var nextUsage;

var delay=2;//two seconds delay.
`
basically what I would like to do is set nextUsage upon start so that it has the value of the time. When the user uses the function, a check will be run to see if the time has passed, if so, use the function and add the delay amount to nextUsage.

I keep getting these two errors however:

NullReferenceException: Object reference not set to an instance of an object
Boo.Lang.Runtime.RuntimeServices.InvokeBinaryOperator (System.String operatorName, System.Object lhs, System.Object rhs)
Movement.Update () (at Assets/Scripts/Movement.js:269)

which point to this line:

`
if(Input.GetButton(“Spin”))
{
if(NextAttackTime>=Time.deltaTime)//line 269
{
NextAttackTime+=AttackDelay;//set the nextattack time
spinattack();
}

}

`

I’m a little confused. Any ideas?

for something like this I actually just use Invoke.

when the player hits the attack key and I want to wait half a second for the animation to sync up for example:

Invoke("DoAttack", .5f); // this will call the function DoAttack in .5 seconds.

edit: or are you talking about something like a cooldown? if so, then DaveA's example works fine for that.

Untested

var nextUsage;
var delay=2;//two seconds delay.

function Start()
{
  nextUsage = Time.time + delay;
}

function Update()
{
  if (Time.time > nextUsage)
  {
    nextUsage = Time.time + delay;
    .. do stuff...

Perhaps this could help:

Example:

yield WaitForSeconds(delay);

I hope that helps you somehow
