1180: Call to a possibly undefined method addEventListener

1

I’m trying to create a little movie that has popcorn flying all over.

I have the graphics in a .fla file, whose Document class is linked to the file below (let’s call it Physics), but I continue to get this error:

1180: Call to a possibly undefined method addEventListener.

Code:


package 
	{
	import flash.display.*;
	import flash.events.Event;
	import Pop;

// an array in which to store our particles
var particles:Array = new Array(); 

// call frameLoop every frame
addEventListener(Event.ENTER_FRAME, frameLoop); 

function frameLoop(e:Event)
{
	var particle:Pop;

	// loop through the array of particles and update each one
	for(var i : int = 0; i < particles.length; i++)
	{
		// update the particle at index i
		particles*.update(); 
	}
	
	
	// make a new particle
	particle = new Pop(Popcorn, this, 150,125); 

	// set our particle's velocity
	particle.xVel = randRange(-7,7); 
	particle.yVel = randRange(-10,-5);
	
	// add drag
	particle.drag = 0.99; 
	// add gravity
	particle.gravity = 0.4;
	
	// randomise initial particle size
	particle.clip.scaleX = particle.clip.scaleY = randRange(0.1,2.5); 
	// add shrink
	particle.shrink = 0.98; 
	
	// and add it to the array of particles
	particles.push(particle); 

	
	// if there are more than 100 particles delete the first 
	// one in the array... 
	while(particles.length>100)
	{
		particle = particles.shift();
		particle.destroy();
		
	}
	
}

// returns a random value between min and max
function randRange(min:Number, max:Number)
{
	return Math.random()*(max-min)+min; 
}
}
