我在游戏中运行的方式是检测到你点击了一个Movieclip的运行按钮，然后它设置了增加的walkpeeds。如果抬起手指，或将其从按钮上移开，它会将其恢复为默认的速度梯度。
所以，问题是运行按钮仅在定向DPAD之前按下时才有效。
我该如何解决这个问题？

编辑：
以下是我的动作：
有一个动画片段绑定到播放器的坐标。这就是动画设置其x和y坐标的原因。 如果玩家开始移动，则inMotion变量变为true，这意味着玩家正在移动。 玩家进入的方向的变量也将改变（如果他向左移动，则goLeft = true）
如果玩家遇到某些东西，或者让我们在DPAD上指示方向，那么inMotion就是假的。
这样做可以在适当的时间将动画添加到舞台上，并在适当的时间进行动画处理。 例如：
我按左DPAD
inMotion = true，goingLeft = true
如果舞台上没有左侧动画，请将其添加到舞台上。
左侧动画检测到变量会相应地响应它们： inMotion＆amp;＆amp; goingLeft 向左移动方向 ！inMotion＆amp;＆amp; ！goingLeft 然后闲着，不要动画 inMotion＆amp;＆amp; ！goingLeft 在另一个方向移动，删除动画
我向右按DPAD 遵循上面提到的相同周期
这确保在正确的时间播放正确的动画，并且此代码可能比 它必须是，但这实际上显示了我在代码中所知道的限制。
答案 0 :(得分：0)
只要看到2个看起来相似的代码块，就知道代码是错误的：https://en.wikipedia.org/wiki/Duplicate_code。公式 less code = better 始终是正确的。
空代码块会降低可读性：
// Bad.
if (condition)
{
}
else
{
// some code
}
// Good.
if (!condition)
{
// some code
}
您还可以将多个条件叠加到一个 if 的情况下，逻辑和＆amp;＆amp;逻辑或 ||除非它变得不可读：
// Bad.
if (conditiona)
{
if (conditionb)
{
if (conditionc)
{
}
else
{
// some code
}
}
}
// Better.
if (conditiona && conditionb && !conditionc)
{
// some code
}
如果你的目标是分配一个变量，而不是如果的攻击，你就可以使用一个ternar运算符。同样，除非可读性下降：
var foo:*;
// Block of ifs.
if (conditiona)
{
foo = 1;
}
else if (conditionb)
{
foo = 2;
}
// Ternar assignment.
var foo:* = conditiona? 1: conditionb? 2: foo;
// Ternar assignment in a more readable form.
var foo:* = conditiona? 1: (conditionb? 2: foo);
因此，您的代码应用了上述所有内容：
function setDirection(tox:Number, toy:Number):void
{
Game.goingUp = (toy < 0);
Game.goingDown = (toy > 0);
Game.goingLeft = (tox < 0);
Game.goingRight = (tox > 0);
main._Direction.y = Game.goingUp ? Game.upWalkspeed : Game.goingDown ? Game.downWalkspeed : 0;
main._Direction.x = Game.goingLeft? Game.leftWalkspeed: Game.goingRight? Game.rightWalkspeed: 0;
}
function onDown(e:TouchEvent):void
{
if (Game.player1 && !P1UAnim_mc)
{
var P1UAnim_mc:MovieClip = new mc_P1UAnim();
addChild(P1UAnim_mc);
}
if (Game.player2 && !P2UAnim_mc)
{
var P2UAnim_mc:MovieClip = new mc_P2UAnim();
addChild(P2UAnim_mc);
}
switch (e.currentTarget)
{
case main.up_dpad :
setDirection(0,-1);
break;
case main.down_dpad :
setDirection(0,1);
break;
case main.left_dpad :
setDirection(-1,0);
break;
case main.right_dpad :
setDirection(1,0);
break;
}
if (!Game.inMotion)
{
Game.inMotion = true;
addEventListener(Event.ENTER_FRAME, onFrame);
}
}
您还可以通过在Flash IDE（Animate或CS6或其中的任何一个）中设计UI来节省编程UI布局。您在库中设计MovieClip，以便它在正确的位置具有您需要的所有接口。您需要评估的所有UI元素都必须具有实例名称。然后为这个MovieClip创建一个类：
package
{
public class Layout extends MovieClip
{
// Left, Right, Up and Down are instance names of the objects
// in your designed MovieClip. Their accessors must be public.
// Also you should understand what classes they should be:
// SimpleButton for button object, TextField or TLFTextField
// for texts, MovieClip or Sprite for containers.
public var Left :SimpleButton;
public var Right:SimpleButton;
public var Up :SimpleButton;
public var Down :SimpleButton;
// Then if you set everything right you can access then
// in the class constructor with no need to create them
// or set them up as they are already in their places by design.
function Layout()
{
super();
Left.addEventListener(...);
}
}
}
