我在Flash中創建障礙時遇到了麻煩。我設法設法制造了障礙，但只有在沒有背景的情況下才能看到。當添加一個他們完全消失......在AS3中創建障礙
下面是該main.as文件的代碼：
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.filters.BitmapFilterQuality;
import flash.filters.BlurFilter;
import flash.utils.setInterval;
import flash.utils.clearInterval;
public class Main extends MovieClip {
private var obstacleArray:Array;
private var obstacleInterval:uint;
private var rural2:Rural2;
private var rural3:Rural2;
private var cityFront2:CityFront2;
private var cityFront3:CityFront2;
private var cityBack2:CityBack2;
private var cityBack3:CityBack2;
private var skyline:Skyline;
private var skyline2:Skyline;
public var ship:Ship;
public function Main() {
// constructor code
obstacleArray = new Array();
obstacleInterval = setInterval(createObstacle, 1000);
addSkylineToStage();
addCityBack2ToStage();
addCityFront2ToStage();
addRural2ToStage();
createShip();
addEventListener(Event.ENTER_FRAME, onEnterFrame);
}
private function addSkylineToStage() {
skyline = new Skyline();
/*var myBlurFilter:BlurFilter = new BlurFilter(8,8);
skyline.filters = [myBlurFilter];*/
stage.addChild(skyline);
skyline2 = new Skyline();
skyline2.x = skyline.width;
stage.addChild(skyline2);
}
private function addCityBack2ToStage() {
cityBack2 = new CityBack2();
cityBack2.y = 310;
cityBack2.x = 20;
var myBlurFilter:BlurFilter = new BlurFilter(3.7,3.7);
cityBack2.filters = [myBlurFilter];
stage.addChild(cityBack2);
cityBack3 = new CityBack2();
cityBack3.y = 310;
cityBack3.x = cityBack2.width-20;
cityBack3.filters = [myBlurFilter];
stage.addChild(cityBack3);
}
private function addCityFront2ToStage() {
cityFront2 = new CityFront2();
cityFront2.y = 310;
var myBlurFilter:BlurFilter = new BlurFilter(2.3,2.3);
cityFront2.filters = [myBlurFilter];
stage.addChild(cityFront2);
cityFront3 = new CityFront2();
cityFront3.y = 310;
cityFront3.x = cityFront2.width-8;
cityFront3.filters = [myBlurFilter];
stage.addChild(cityFront3);
}
private function addRural2ToStage() {
rural2 = new Rural2();
rural2.y = 410;
stage.addChild(rural2);
rural3 = new Rural2();
rural3.y = 410;
rural3.x = rural2.width-2;
stage.addChild(rural3);
}
var position:String = 'bottom';
private function createObstacle(){
if(position == 'bottom'){
position = 'top';
}else{
position = 'bottom';
}
var obstacle:Obstacle = new Obstacle(stage,position);
obstacleArray.push(obstacle);
obstacle.x = stage.stageWidth;
addChild(obstacle);
}
private function stopObstacles(){
for(var i:int = 0; i<obstacleArray.length;i++){
var obstacle:Obstacle = obstacleArray[i];
obstacle.removeEvents();
}
clearInterval(obstacleInterval);
}
private function onEnterFrame(evt:Event) {
rural2.x -= 2;
rural3.x -= 2;
if(rural2.x <= -rural2.width){
rural2.x = rural3.width-4;
}
if(rural3.x <= -rural3.width){
rural3.x = rural2.width-4;
}
cityFront2.x -= 1;
cityFront3.x -= 1;
if(cityFront2.x <= -cityFront2.width){
cityFront2.x = cityFront3.width-15;
}
if(cityFront3.x <= -cityFront3.width){
cityFront3.x = cityFront2.width-15;
}
cityBack2.x -= 0.5;
cityBack3.x -= 0.5;
if(cityBack2.x <= -cityBack2.width){
cityBack2.x = cityBack3.width-50;
}
if(cityBack3.x <= -cityBack3.width){
cityBack3.x = cityBack2.width-50;
}
skyline.x -= 0.25;
skyline2.x -= 0.25;
if(skyline.x <= -skyline.width){
skyline.x = skyline2.width-2;
}
if(skyline2.x <= -skyline2.width){
skyline2.x = skyline.width-2;
}
for(var i:int = 0; i<obstacleArray.length; i++){
var obstacle:Obstacle = obstacleArray[i];
if(obstacle.hitTestObject(ship)){
stage.removeEventListener(Event.ENTER_FRAME, onEnterFrame);
stopObstacles();
}
}
}
public function createShip() {
ship = new Ship(stage);
stage.addChild(ship);
ship.x = 20;
ship.y = 180;
}
}
}
而對於obstacles.as文件的代碼：
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.display.Stage;
public class Obstacle extends MovieClip {
private var speed:Number = 3;
private var mPosition:String;
private var mStage:Stage;
public function Obstacle(stage:Stage, position:String = 'bottom') {
// constructor code
mPosition = position;
mStage = stage;
addEvents();
setPosition();
}
private function setPosition(){
var factor:Number = Math.random()+0.3;
this.scaleY = factor;
if(mPosition == 'bottom'){
this.y = mStage.stageHeight - this.height;
}else{
this.y = 0;
}
}
private function addEvents(){
addEventListener(Event.ENTER_FRAME, onFrame);
}
public function removeEvents(){
removeEventListener(Event.ENTER_FRAME, onFrame);
}
private function onFrame(evt:Event){
this.x -= speed;
}
}
}
我如何調整代碼，所以無論是視差背景和障礙將在可見舞臺？
謝謝！
你不應該在舞臺上添加任何東西，它不是爲了這個。這是一個經典的初學者錯誤。你有自己的顯示列表，使用它。 – BotMaster
