您好可以請你對即時通訊做的嘖嘖幫助... 這是嘖嘖網站http://as3gametuts.com/2012/06/20/platformer-12/comment-page-1/#comment-800閃存碰撞
和好吧，我不知道什麼的代碼問題，子彈心不是與敵人碰撞..這是它的代碼..
function fireBullet():void {
var playerDirection:String;
if(player.scaleX < 0){
playerDirection = "left";
} else if(player.scaleX > 0){
playerDirection = "right";
}
var bullet:Bullet = new Bullet(player.x - scrollX, player.y - scrollY, playerDirection, xSpeed);
back.addChild(bullet);
bulletList.push(bullet);
bullet.addEventListener(Event.REMOVED, bulletRemoved);
}
var bulletList:Array = new Array();
function bulletRemoved(e:Event):void {
e.currentTarget.removeEventListener(Event.REMOVED, bulletRemoved); //this just removes the eventListener so we don't get an error
bulletList.splice(bulletList.indexOf(e.currentTarget), 1); //this removes 1 object from the bulletList, at the index of whatever object caused this function to activate
}
//bullet
//enemies
var enemyList:Array = new Array();
function addEnemy(xLocation:int, yLocation:int):void{
var enemy:Enemy = new Enemy(xLocation, yLocation);
back.addChild(enemy);
enemy.addEventListener(Event.REMOVED, enemyRemoved);
enemyList.push(enemy);
}
function addEnemy1(xLocation:int, yLocation:int):void{
var enemy1:Enemy1 = new Enemy1(xLocation, yLocation);
back.addChild(enemy1);
enemy1.addEventListener(Event.REMOVED, enemyRemoved);
enemyList.push(enemy1);
}
function enemyRemoved(e:Event):void{
e.currentTarget.removeEventListener(Event.REMOVED, enemyRemoved); //this just removes the eventListener so we don't get an error
enemyList.splice(enemyList.indexOf(e.currentTarget), 1); //this removes 1 object from the enemyList, at the index of whatever object caused this function to activate
}
addEnemiesToLevel1();
function addEnemiesToLevel1():void{
addEnemy(272.8, 19.8);
addEnemy(959, 278.8);
addEnemy1(374.1, 305.1);
addEnemy1(966, 29);
}
這是主循環
