Creating a small delay for a Pick up/drop script.

Questions & Answers

Alright, so I'm having a delay problem with a pickup script. Well rather, I can't get a delay working. I've looked through a bunch of delay answers on here, but I can't get any of them to work. Here is a snippet of what I'm working with:

function Update () {
    if( timer > seconds.getSecondsFloat() +3)
        if (Input.GetKeyDown("f") && itemHeld == true) {
            object.transform.parent = null;
            object = null;          
            held = false;
        }

}

function OnTriggerStay(collider : Collider){
if (Input.GetKeyDown("f") && collider.tag == "hands")
if (itemHeld == false){
Debug.Log("i see you keep hitting me, there");
aquireObject();
}
}
function OnTriggerEnter(collider : Collider){
if (Input.GetKeyDown("f") && collider.tag == "hands")
if (itemHeld == false){
Debug.Log("i see you hit me, there");
aquireObject();
}
}

It works, to pick up the object. But the command executes so fast that when I go to set the object down it will pick it back up. I've tried setting a counter that increments on every frame and I put in an if condition for if (counter > 60), but then I can't even pick up the object. I've tried a coroutine, but to be honest I can't find too much information on them. I could have done it wrong. I had startcoroutine(functionthatyields) and yielded 3 seconds. I called it inside the if condition an everything. But I'm not sure how to get this working. :|

You left out the code for dropping and any of your timer work. I'm not really sure what you're doing with the trigger either. If you're not going to include the meaningful portions of your code, it's much harder to know what you've done wrong.

The general way to do this is with a lock, be it a boolean or a timer.

BooleanLock.js

var busy : boolean = false; //Lock

function Update() {
    if(!busy && something) DoThing();
}

function DoThing() {
    busy = true; //get the lock
    //do stuff...
    yield WaitForSeconds (waitTime); //If you want to impose some wait time
    busy = false; //release the lock
}

TimerLock.js

var busyTimer : float = 0.0; //Lock

function Update() {
    if(busyTimer > 0) busyTimer -= Time.deltaTime; //Releasing the lock
    if(busyTimer <= 0 && something) DoThing();
}

function DoThing() {
    busyTimer = waitTime; //get the lock
    //do stuff...
}

If you really want to wait for your function to finish, rather than use a lock, you can yield the start of the coroutine;

WaitToFinish.js

function Update() {
    if(something) yield StartCoroutine(DoThing());
}

function DoThing() {
    //do stuff...
    yield WaitForSeconds (waitTime);
}
