How to Make a Vertical Shooter in AS3 – Part 6
Part 6: Finishing Touches
As always, the finishing touches of this game won’t be explained too much by me, in hopes that you actually can do some of this stuff by yourself. Of course, there will always be source files at the bottom if you need to clear anything up.
The first thing I want to do is show the score on the “lose” screen. That’ll be pretty easy, just add a dynamic text field there.
Next, we can make some particles move down the screen so it looks like the player is actually moving forward. We’re going to make them the same speed as the enemies. I’m actually show some code for this one, because it’s also a pretty new thing for me. We’re not going to make a MovieClip for this, we’re going to make dynamic shapes through ActionScript. Here’s the code to place at the bottom:
//adding another enterframe listener for the particles stage.addEventListener(Event.ENTER_FRAME, generateParticles); //checking if there already is another particlecontainer there if(particleContainer == null){ //this movieclip will hold all of the particles var particleContainer:MovieClip = new MovieClip(); addChild(particleContainer); } function generateParticles(event:Event):void{ //so we don't do it every frame, we'll do it randomly if(Math.random()*10 < 2){ //creating a new shape var mcParticle:Shape = new Shape(); //making random dimensions (only ranges from 1-5 px) var dimensions:int = int(Math.random()*5)+1; //add color to the shape mcParticle.graphics.beginFill(0x999999/*The color for shape*/,1/*The alpha for the shape*/); //turning the shape into a square mcParticle.graphics.drawRect(dimensions,dimensions,dimensions,dimensions); //change the coordinates of the particle mcParticle.x = int(Math.random()*stage.stageWidth); mcParticle.y = -10; //adding the particle to stage particleContainer.addChild(mcParticle); } //making all of the particles move down stage for(var i:int=0;i<particleContainer.numChildren;i++){ //getting a certain particle var theParticle:Object = particleContainer.getChildAt(i); //it'll go half the speed of the character theParticle.y += mainSpeed*.5; //checking if the particle is offstage if(theParticle.y >= 400){ //remove it particleContainer.removeChild(theParticle); } } }
Pretty intense, eh? Well, this is a finishing touch, and most finishing touches are pretty intense. If you want to, you can remove this function when the player loses, but I won’t because it adds a pretty cool effect.
Well, that’s actually all that I really have to finish off the game. I hope you had fun making it!
