AS3儿童问题的if语句 [英] AS3 child issue with if statements

问题描述

好了，有人可以解释什么是错我的code以下，没有错误，但它没有做什么，我想要它做的。予需要它来在屏幕上显示一个movieclip时称为randint变量，它是由随机产生的，大于或等于0.5。如果不是那么它不会显示。 code：

 的addEventListener（Event.ENTER_FRAME，char_coll）;
功能char_coll（EV：事件）：无效
{
    如果（currentFrame == 2）
    {
        如果（randint＆GT = 0.5）{
            VAR W1：woman1 =新woman1（）;
            randint =的Math.random（）;
            如果（w1.hitTestObject（支架））{
                w1.gotoAndPlay（1）;
                cash1 = cash1 + 1;
        }
        }

    }
};
 

解决方案

randint 设置if语句中。这意味着 randint 总是undefiend，因为它必须是＆GT; = 0.5 设置为任意值（样一个catch 22）。

这code应该工作：

 的addEventListener（Event.ENTER_FRAME，char_coll）;
功能char_coll（EV：事件）：无效
{
    如果（currentFrame == 2）
    {
        VAR randint：数=的Math.random（）;
        如果（randint＆GT = 0.5）{
            VAR W1：woman1 =新woman1（）;
            stage.addChild（W1）;
            如果（w1.hitTestObject（支架））{
                w1.gotoAndPlay（1）;
                cash1 = cash1 + 1;
            }
        }

    }
};
 

那当然，你必须添加 W1 到的addChild（）阶段使用，您可以参见下面的变种 W1：woman1 =新woman1（）;

希望它能帮助！

Alright, can someone explain what is wrong with my code below, there is no errors, but it's not doing what I want it to do. I need it to display a movieclip on the screen when a variable called "randint", which is generated by random, is greater than or equal to 0.5. If it's not then it doesn't get displayed. Code:

addEventListener(Event.ENTER_FRAME, char_coll);
function char_coll(ev : Event) : void
{
    if(currentFrame==2)
    {
        if (randint >= 0.5){
            var w1:woman1 = new woman1();
            randint = Math.random();
            if(w1.hitTestObject(stand)){
                w1.gotoAndPlay(1);
                cash1 = cash1 + 1;
        }
        }

    }
};

解决方案

randint is set inside the if statement. This means that randint always is undefiend, because it has to be >= 0.5 to be set to any value (kind of a catch 22).

This code should work:

addEventListener(Event.ENTER_FRAME, char_coll);
function char_coll(ev : Event) : void
{
    if(currentFrame==2)
    {
        var randint:Number = Math.random();
        if (randint >= 0.5){
            var w1:woman1 = new woman1();
            stage.addChild(w1);
            if(w1.hitTestObject(stand)){
                w1.gotoAndPlay(1);
                cash1 = cash1 + 1;
            }
        }

    }
};

Then of course you have to add w1 to the stage using addChild() as you can se below var w1:woman1 = new woman1();

hope it helps!
