if(condition) ... 如何用？

請救命．．．
小生想寫一段flash的action scirpt....

以下是小生寫的一段flash的action scirpt：

on (keyPress "<End>") {
        _root.spec2._width =(_width+2)
        _root.spec2._height =(_height+2)
}

on (keyPress "<down>") {
        _root.spec2._width =(_width-2)
        _root.spec2._height =(_height-2)}

它能令小生的"object"隨著按"<End>" 与"<down>"變大變小．．．
但，小生希望能夠做到“只有“當用mouse按著"object"時，然後隨著按"<End>" 与"<down>""object"才會變大變小．．．

請幫幫忙！
小生是用flash MX的

謝謝

你的这个 code 是写在你的 button instance 上对吧？
然后在 _root 上你有一个 instance name 为 spec2 的 movieclip 对吧？

：：：：：：：
在 spec2 的 movieclip 上写
onClipEvent(load){
    this.onPress = function(){
        this.__userpress = true
    }
    this.onRelease = this.onReleaseOutside = function(){
        this.__userpress = false
    }
}


在 button 上的改为
on (keyPress "<End>" ) {
    var mc = _root.spec2
    if(mc.__userpress){
        mc._width += 2
        mc._height += 2
    }
}
on (keyPress "<down>" ) {
    var mc = _root.spec2
    if(mc.__userpress){
        mc._width -= 2
        mc._height -= 2
    }
}


酱子应该可以达到你的要求（没测试过，因为目前没有安装 Flash）

hmm... 你写错地方了，不是在 Time Line 而是在 Instance 上

sson

把 code 换成酱，效果也许会更好
在 _root 的 Time Line 上

var keyObj = new Object();
keyObj.onKeyDown = function() {
        if (_global.__selected_mc != undefined) {
                var mc = _global.__selected_mc;
                var k = Key.getCode();
                switch (k) {
                case Key.UP :
                        mc._xscale += 1;
                        mc._yscale += 1;
                        break;
                case Key.DOWN :
                        mc._xscale -= 1;
                        mc._yscale -= 1;
                        break;
                }
        }
};
Key.addListener(keyObj);

在每一个 MovieClip 上
onClipEvent (load) {
        this.useHandCursor = false;
        this.onPress = function() {
                _global.__selected_mc = this;
        };
}

**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 4: Syntax error.
      ? ? ? ? ? ? ? ? var mc = _global.__selected_mc;

**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 3: Statement must appear within on/onClipEvent handler
      ? ? ? ? if (_global.__selected_mc != undefined) {

**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 5: Syntax error.
      ? ? ? ? ? ? ? ? var k = Key.getCode();

真的非常抱歉，：（
我已經只在 instance 上寫的了！！！

現在，我把他寫在timeline：
var keyObj = new Object();
keyObj.onKeyDown = function() {
? ? ? ? if (_global.__selected_mc != undefined) {
? ? ? ? ? ? ? ? var mc = _global.__selected_mc;
? ? ? ? ? ? ? ? var k = Key.getCode();
? ? ? ? ? ? ? ? switch (k) {
? ? ? ? ? ? ? ? case Key.UP :
? ? ? ? ? ? ? ? ? ? ? ? mc._xscale += 1;
? ? ? ? ? ? ? ? ? ? ? ? mc._yscale += 1;
? ? ? ? ? ? ? ? ? ? ? ? break;
? ? ? ? ? ? ? ? case Key.DOWN :
? ? ? ? ? ? ? ? ? ? ? ? mc._xscale -= 1;
? ? ? ? ? ? ? ? ? ? ? ? mc._yscale -= 1;
? ? ? ? ? ? ? ? ? ? ? ? break;
? ? ? ? ? ? ? ? }
? ? ? ? }
};
Key.addListener(keyObj);


然後把它寫在movie clip 了：
onClipEvent (load) {
? ? ? ? this.useHandCursor = false;
? ? ? ? this.onPress = function() {
? ? ? ? ? ? ? ? _global.__selected_mc = this;
? ? ? ? };
}

THEN............



**Error** Scene=Scene 1, layer=Layer 1, frame=1ine 5: Syntax error.
      ? ? ? ? ? ? ? ? var k = Key.getCode();

**Error** Scene=Scene 1, layer=Layer 1, frame=1ine 2: Syntax error.
      ? ? ? ? this.useHandCursor = false;

**Error** Scene=Scene 1, layer=Layer 1, frame=1ine 3: Syntax error.
      ? ? ? ? this.onPress = function() {

I think you should upload your source file, here is another example:
put all the scripts on timeline frame


myKey = new Object();
myKey.onKeyDown = function() {
        code = Key.getCode();
};
Key.addListener(myKey);

function zoom(mc) {
        eval(mc).onPress = function() {
                this.onEnterFrame = function() {
                        if (code == 35) {
                                if (this._xscale>100) {
                                        this._xscale = this._yscale -= 50;
                                }
                        } else if (code == 36) {
                                this._xscale = this._yscale += 50;
                        }
                        code = 0;
                };
        };
        eval(mc).onRollOut = function() {
                delete this.onEnterFrame;
        }
}
zoom("pic1");  //pic1 can be change to other's instance name
zoom("pic2");



Example - 2004 MX

Use "Home" and "End" button to zoom in and out

super-tomato

try to find some webspace and upload it...

http://www.geocities.com/teik_hean/index.htm

remember yo...
is press, then release, then only "click......"

"up" = 大
"down" = 小
"end" = 不大不小
"control" = 原本的大小

super-tomato

1. it's almost same like my first example file, understand the coding and edit. Don't hope anyone will help you do it

2. What's mean of 不大不小, nobody will know
