hitTest confusion

programming flash
1

hi guys,

I’m a beginner in AS3 only been using as3 for 2 days and I have a problem regarding hitTest

I’m trying to make a First person avoider game where you try to dodge incoming meteors.

Everything is fine, I was able to make the meteors hit the ship I was controlling and I was also able to make the meteors explode upon impact.

The problem is when I try to make the ship “juggle” everytime a meteor hits.

heres the AS file of meteor

        {
            this.target = target;

            else if(movement == 4)
            {
                //move left up
                x -= scaleX/divider;
                y += scaleX/divider;
            }
            else if(movement == 5)
            {
                //move left 
                x -= scaleX/divider;
            }
            else if(movement == 6)
            {
                //move left down
                x -= scaleX/divider;
                y -= scaleX/divider;
            }
            else if(movement == 7)
            {
                //move down
                y -= scaleX/divider;
            }
            else if(movement == 8)
            {
                //move right down
                x += scaleX/divider;
                y -= scaleX/divider;
            }
            else
            {
                x -= scaleX/divider;
            }

            if(checking == 0)
            {
                rotation += 4;
            }
            else
            {
                rotation  = 0;
            }

            
            if(scaleX >= 20)
            {
                if (this.hitTestObject(target.hitter) && checking == 0)
                {
                    if(checking == 0)
                    {
                        checking = 1;
                        this.gotoAndStop(2);// makes this meteor explode
                        target.gotoAndStop(2); // makes ship juggle when hit.
                    }
                }
            }
            
            if(x > 650 || x < -100)
            {
                removeSelf();
            }
            
            if(y > 460 || y < -80)
            {
                removeSelf();
            }
        }
        
        private function removeSelf() : void
        {
            this.removeEventListener('enterFrame', loop)

            if (parent != null)
            {
                parent.removeChild(this);
            }
        }
        
    }
}

The problem is that “target.gotoAndStop(2);” executes even if the ship is not being hit.

Another weird thing is I tried to trace the value of checking and it turns to 1 even if the condition is false. :hat:

This is how I create the meteor


package com.basics1
{
    import flash.display.MovieClip;
    import flash.display.Stage;
    import flash.events.Event;
    import com.particles.Starfield;
    import flash.display.Bitmap;
    import flash.display.Sprite;
    import flash.geom.ColorTransform;
    
    public class Engine extends MovieClip
    {
        var cnt:int = 0;
        var ourShip:Ship = new Ship(stage);
        var randnum:int;
        var randnum2:int;
        
        
            
        public function Engine()
        {
            addEventListener(Event.ENTER_FRAME, loop, false, 0, true);
            stage.addChild(ourShip);

            ourShip.x = stage.stageWidth/2; 
            ourShip.y = stage.stageHeight/2;
            
            addChild(new Starfield());
        }
        
        public function loop(e:Event) : void
        {
            var newMeteor:Meteors = new Meteors(stage, ourShip);
            randnum = Math.floor(Math.random() * (20 - 1 + 1)) + 1;
            
            if(randnum == 5 && cnt < 10)
            {
                trace(randnum);
                cnt += 1;
                stage.addChild(newMeteor);
                newMeteor.name = "meteor" + cnt;
                stage.setChildIndex(newMeteor,1);
                if(cnt == 10)
                {
                    cnt = 0;
                }
            }
        }
    }

}
