我刚开始用as3编码。 现在我正在尝试制作一个玩家只需要避开触摸迷宫内的敌人的游戏。 我设法让玩家和敌人之间以及玩家和墙壁之间发生碰撞。在此之前一切正常。
我面临的问题是： 我无法让敌人独立移动并在与墙壁碰撞后改变他们的动作（方向）。
我试图为墙壁制作一个for循环，并在其中为敌人制作另一个for循环。但所有的敌人似乎都是一体的。当其中一个敌人（来自enemiesArray）与其中一个墙壁（来自wallAray）发生碰撞时，所有敌人都会旋转并向所有方向移动。
我需要的是让敌人单独移动和旋转......
我只是箍有人可以告诉我在我的代码中要改变它的工作原理
我一直在寻找一个左右的解决方案...
这就是我编写代码的方式： 我希望它不会太乱（我还有很多东西需要学习）。

这是我被卡住的地方......我不知道如何让敌人在碰撞后独立移动和旋转。我从这段代码得到的是：它们在碰撞后旋转并移开但是它们一起移动，并且因为它们响应彼此的碰撞，所以每次发生碰撞时它们都会保持碰撞和旋转。
//Enemy Collision with the walls (NOT WORKING)
var nr:uint = Math.round(Math.random()*3);
function enemyWallCollision(){
for(var i:uint = 0; i < enemiesArray.length;i++){
var enemy:MovieClip = enemiesArray[i];
for(var j:uint = 0; j < wallArray.length;j++){
var wall:MovieClip = wallArray[j];
if(enemy.hitTestObject(wall)){
if (eDir == "LEFT"){
enemy.x += enemySpeed;
}
if (eDir == "RIGHT"){
enemy.x -= enemySpeed;
trace("hopa");
}
if (eDir == "UP"){
enemy.y += enemySpeed;
}
if (eDir == "DOWN"){
enemy.y -=enemySpeed;
}
//break;
var nr:uint = Math.round(Math.random()*3);
eDir = eDirArray[nr];
}
}
}
}
这是代码的其余部分......
