Need help with programming an enemy for a platformer.

[ferretg]

I am trying to make an enemy for a side-scrolling platformer game that is similar to the green turtle in Super Mario. It needs to go 1 direction 1st then either turn when hitting a wall or fall if it walks over the edge. I am programming using separate as files connected together and so far have come up with the following code files.

enemy_test.as:

package
{
import flash.display.MovieClip;
import flash.utils.Timer;
import flash.events.TimerEvent;
public class inkman_enTest extends MovieClip
{

public var Enemy:enemy;
public var walls:Array;
public var gtimer:Timer;
public function inkman_enTest()
{
walls = new Array();
Enemy = new enemy();
addChild( Enemy );

gtimer= new Timer(25);
gtimer.addEventListener(TimerEvent.TIMER, gameLoop);
gtimer.start();
}

function gameLoop(loop:TimerEvent):void
{
Enemy.en_move();
}
}
}

enemy.as:

package
{
import flash.display.MovieClip;
public class enemy extends MovieClip
{
public function en_start()
{
x= 100; // Variables for enemy starting place.
y= 10;//
}
public function en_move():void
{
this.x +=3;// Initial movement

}
}
}

wall.as:

package
{
import flash.display.MovieClip;
public class Wall extends MovieClip
{
public var WIDTH:int = 32;

public var HEIGHT:int = 32;

}

}

Any help would be appreciated. If not can I you point me to a website or forum where I can get more information. Thanks.

Could you explain how it's working or not working?

Well right now now it has the enemy object appear on the 0,0 x/y coordinates on the stage even though I have it set in the enemy.as to appear on 100x and 10y, . Since I am mainly programming the A.I. of the enemy and not the whole game I have a small stage of 400 x 200 pixels but I don't think that's the problem of where the enemy is placed.

Right now the enemy will only travel in a straight line to the left so I got that part completed, ideally what I am also trying to accomplish is for the enemy to move the opposite direction when hitting a wall object and falling when not detecting any wall object below it.

I realize that I will have to set up the enemy as an array object so I can place as many instances of it that are needed in the various game stages but I anm at a loss of how to program this.

Is there anyone who can help at all or point me to another resource or forum that could help?

It seems to me that you are probably having a hard time coming up with a solution because you don't have a very good system in place for solving problems like this. Allow me to suggest then a tile based approach.

is what you're looking for. start at the first tutorial and work your way up and this problem shouldn't be too difficult

You don't call the en_start() function anywhere, so it's no wonder that when you add the enemy to the stage it's at the origin. And where are your constructors?
