Creating traffics lights

[felkob]

Hello. I am creating traffic lights, but I'm new to flash. I have a timer that ticks 6 times. However, I want to make the timer refresh after 6, and on each tick, a different traffic light shows.

So far I have this:


var myTimer:Timer = new Timer(2000,6);

var counter:Number = 0;

myTimer.start();

myTimer.addEventListener(TimerEvent.TIMER, onRemind);

function onRemind(evt:TimerEvent):void
{
counter += 1;
trace("reminder "+ counter);
}

Sorry for the double post, I don't see an edit button?

if (counter==1)
{
trafficlight.gotoAndPlay('stop');
}

if (counter==2)
{
trafficlight.gotoAndPlay('ready');
}

if (counter==3)
{
trafficlight.gotoAndPlay('go');
}

I know this is wrong though....

Just put that last code inside the function:

var myTimer:Timer = new Timer(2000,6);

var counter:Number = 0;

myTimer.start();

myTimer.addEventListener(TimerEvent.TIMER, onRemind);

function onRemind(evt:TimerEvent):void
{
    counter += 1;
    trace("reminder "+ counter);
    if (counter==1)
    {
        trafficlight.gotoAndPlay('stop');
    }
    
    if (counter==2)
    {
        trafficlight.gotoAndPlay('ready');
    }
    
    if (counter==3)
    {
        trafficlight.gotoAndPlay('go');
    }
}

It still doesn't work.

I changed the code, and I currently have:

import flash.utils.Timer;

//set lights in start state
var flowIsEW:Boolean = true;
startState();

function startState()
{
//only use two of the lights for now!
this.lightN.gotoAndStop("stop");
this.lightW.gotoAndStop("go");
//park two of the lights for a while;
this.lightS.gotoAndStop("allOff");
this.lightE.gotoAndStop("allOff");
}



var flowTimer:Timer = new Timer(5000,1);
flowTimer.addEventListener(TimerEvent.TIMER,swapFl ow);
flowTimer.start();

var changeTimer:Timer = new Timer(2000);
changeTimer.addEventListener(TimerEvent.TIMER,lamp Change);

//swap the traffic flow on each ticker of the flow timer;
function swapFlow(evt:TimerEvent):void
{
flowIsEW = ! flowIsEW;

changeTimer.start();
trace("flow of traffic is swapped");
trace(flowIsEW);

if (flowIsEW)
{
this.lightN.gotoAndStop("stop");
this.lightW.gotoAndStop("go");
}
if (! flowIsEW)
{
this.lightN.gotoAndStop("go");
this.lightW.gotoAndStop("stop");
}
flowTimer.reset();
}

function lampChange(evt:TimerEvent):void
{
trace("lamps change");
}

However that just has 2 lights not moving. One on stop, one on go.

Mind postin your FLA file?

Here it is so far...

Mind downsaving it to CS5 or CS4?

[felkob]

Cs4.

The logic has errs, use an else statement. Also, there are linear errs.

Not sure what your aiming for, but this works:

import flash.utils.Timer;

//set lights in start state
var flowIsEW:Boolean ;

var flowTimer:Timer = new Timer(2000,10);
flowTimer.addEventListener(TimerEvent.TIMER,swapFlow);
flowTimer.start();

var changeTimer:Timer = new Timer(2000, 10);
changeTimer.addEventListener(TimerEvent.TIMER,lampChange);
function startState()
{
	//only use two of the lights for now!
	this.lightN.gotoAndStop("stop");
	this.lightW.gotoAndStop("go");
	//park two of the lights for a while;
	this.lightS.gotoAndStop("allOff");
	this.lightE.gotoAndStop("allOff");
	flowIsEW = false;
}

//swap the traffic flow on each ticker of the flow timer;
function swapFlow(evt:TimerEvent):void
{
	
	//changeTimer.start();
	trace("flow of traffic is swapped");
	trace(flowIsEW);
	if (flowIsEW==true)
	{
		this.lightN.gotoAndStop("stop");
		this.lightW.gotoAndStop("go");
		flowIsEW = false;
	}
	else if (flowIsEW==false)
	{
		this.lightN.gotoAndStop("go");
		this.lightW.gotoAndStop("stop");
		flowIsEW =  true;
	}
	//flowTimer.reset();
}

function lampChange(evt:TimerEvent):void
{
	trace("lamps change");
	swapFlow(evt);
}
startState();
