Question

问题是我在游戏中遇到了战斗机的麻烦。如果我使用KEY_DOWN事件和/或ENTER_FRAME，当我按住踢或打孔按钮时，战斗机不断对敌人造成伤害，但是我要他，或者他要么踢，然后回到静止位置或踢，并且能够保持位置，但只造成一次伤害。这是一些代码：

stage.addEventListener(KeyboardEvent.KEY_DOWN, enterAttack);
stage.addEventListener(KeyboardEvent.KEY_UP, exitAttack);
stage.addEventListener(Event.ENTER_FRAME, attackYes);
stage.addEventListener(Event.EXIT_FRAME, attackNo);

function enterAttack(evt:KeyboardEvent):void
{
    if (evt.keyCode == 84)
    {
        attack = true;
    }
}
function exitAttack(evt:KeyboardEvent):void
{
    attack = false;
}
function attackYes(evt:Event):void
{
    if (attack)
    {
        hero.gotoAndStop("punch1");

        checkHitRed();
        checkIfDead();
    }
}
function attackNo(evt:Event):void
{
    if (!attack)
    {
        hero.gotoAndStop("still");
    }
}

我试图在某个地方移除听众，但这总是让战士看起来没有做任何攻击。

有没有办法防止按下踢/打孔按钮？

感谢任何帮助

人物状态，分为三种类型。如下。

stage.addEventListener(KeyboardEvent.KEY_DOWN, enterAttack);
stage.addEventListener(KeyboardEvent.KEY_UP, exitAttack);
stage.addEventListener(Event.ENTER_FRAME, onAction);

var characterState:String = "wait"
function enterAttack(evt:KeyboardEvent):void
{
    if (evt.keyCode == 84)
    {
        characterState = "attack";
    }
}
function exitAttack(evt:KeyboardEvent):void
{
    characterState = "attack_ended";
}
function onAction(evt:Event):void
{
    if(characterState == "wait") return;

    if(characterState == "attack")
    {
        hero.gotoAndStop("punch1");

        checkHitRed();
        checkIfDead();
    }
    else if(characterState == "attack_ended")
    {
        hero.gotoAndStop("still");
        //Revert to wait state after the attack termination .
        characterState = "wait";
    }
}

你必须为你的能力设计冷却时间，例如：＆＃34;踢＆＃34;每20帧只能发生一次。因此，当玩家按下踢球按钮时，char会踢，踢伤，并设置冷却变量。输入帧侦听器开始递减计数器，并且在冷却激活时忽略后续的踢命令。

stage.addEventListener(KeyboardEvent.KEY_DOWN, enterAttack);
stage.addEventListener(Event.ENTER_FRAME, enterFrame);
var kickCooldown:int=0;
function enterAttack(evt:KeyboardEvent):void
{
    if (evt.keyCode == 84)
    {
        if (!kickCooldown) {
            attack = true;
            kickCooldown=15;
        }
    }
}
function enterFrame(evt:Event):void
{
    if (attack)
    {
        hero.gotoAndStop("punch1");
        attack=false; // we have attacked once, now dealing damage
        checkHitRed();
        checkIfDead();
    }
    if (kickCooldown>0) kickCooldown--; // waiting for cooldown end
    else hero.gotoAndStop("still"); // if ends, return hero to "still" posture
}
