Hey

I’m pretty new to action script and have been asked to create flocking behaviar with a seeker that the flock moves away from.

I managed to find some code for flocking and seeking in separate classes and am having trouble putting them in the same class so the seeker seeks the flock.

I have attached all relavant movement files.

Any help will be much appreciated.

package  
{  
import com.foed.SteeredVehicle;  
import com.foed.Vector2D;  
import com.foed.Vehicle;

import flash.display.Sprite;  
import flash.display.StageAlign;  
import flash.display.StageScaleMode;  
import flash.events.Event;

public class FlockTest extends Sprite  
{  
private var \_vehicles:Array;  
private var \_numVehicles:int = 30;  
private var \_seeker:SteeredVehicle;  
private var \_fleer:SteeredVehicle;

public function FlockTest()  
{  
stage.align = StageAlign.TOP\_LEFT;  
stage.scaleMode = StageScaleMode.NO\_SCALE;

\_vehicles = new Array();  
for(var i:int = 0; i \< \_numVehicles; i++)  
{  
var vehicle:SteeredVehicle = new SteeredVehicle();  
vehicle.position = new Vector2D(Math.random() \* stage.stageWidth, Math.random() \* stage.stageHeight);  
vehicle.velocity = new Vector2D(Math.random() \* 20 - 10, Math.random() \* 20 - 10);  
vehicle.edgeBehavior = Vehicle.BOUNCE;  
\_vehicles.push(vehicle);  
addChild(vehicle);  
}  
addEventListener(Event.ENTER\_FRAME, onEnterFrame);  
}  
public function SeekFleeTest1()  
{  
stage.align = StageAlign.TOP\_LEFT;  
stage.scaleMode = StageScaleMode.NO\_SCALE;

\_seeker = new SteeredVehicle();  
\_seeker.position = new Vector2D(200, 200);  
\_seeker.edgeBehavior = Vehicle.BOUNCE;  
addChild(\_seeker);

\_fleer = new SteeredVehicle();  
\_fleer.position = new Vector2D(400, 300);  
\_fleer.edgeBehavior = Vehicle.BOUNCE;  
addChild(\_fleer);  
}

private function onEnterFrame(event:Event):void  
{  
for(var i:int = 0; i \< \_numVehicles; i++)  
{  
\_vehicles\*.flock(\_vehicles);\*  
_\_vehicles_.update();\*  
_}_  
_\_seeker.seek(\_fleer.position);_  
_\_fleer.flee(\_seeker.position);_  
_\_seeker.update();_  
_\_fleer.update();_  
_}_  
_}_  
_}_

_As Mentioned above._  
_I want to create a flocking behavour FlockTest.as that has a predator pursueing it SeekFleeTest.as. I am having trouble combining the code together._

_Thank you_\*
