Mouse Wheel для приближения карты

ilikali · 03.04.2010, 22:51

Есть карта.Все работает прекрасно вот только заказчик попросил чтоб ползунок приближения работал с помощью ползунка мыши. вот код самой работы

Код AS1/AS2:

stageW = 982;

alphaSpeed = 5;
moveAmount = 20;
zoomAmount = 3;
cropWidth = stageW;
cropHeight = stageH;
destAlpha = 0;
ID = 0;
 
 
// Set the mousewheel scroll speed here
scrollSpeed = 10
 
var mouseListener:Object = new Object(this);
mouseListener.onMouseWheel = function(wheelNum:Number) {
	if (scroll_mc.scrollBttn._y>=scroll_mc.scrollBttn.originY)

на сколько видно из кода есть мувик с именем scroll_mc в нем находятся scrollBttn и gridBttn.нужно сделать так чтоб когда пользователь крутил скрол на мыше карта приближалась.Помогите пожалуйста.

Код AS1/AS2:

new Object(this)
...
bttnRight.bttn.onRelease = (bttnRight.bttn.onReleaseOutside=function () {
	delete bttnRight.onEnterFrame;
});

Что-то я вот этих конструкций не понял. Это я туплю?

А по вопросу — сложно разобраться, что у вас в коде происходит.

Да код написан под другую игрушку не охотно было разбирать вот и поставил как есть.(В принципе я и не ахти во AS так что и разобраться было бы очень сложно) По началу этот код был предназначен для просмотра больших изображений а я его под себя сделал. У меня там есть код который вроде отвечает за прокрутку

Код AS1/AS2:

// Set the mousewheel scroll speed here
scrollSpeed = 10
 
var mouseListener:Object = new Object(this);
mouseListener.onMouseWheel = function(wheelNum:Number) {
	if (scroll_mc.scrollBttn._y>=scroll_mc.scrollBttn.originY) 
	{
		scroll_mc.scrollBttn._y -= (wheelNum/scrollRatio)*scrollSpeed;
		if (scroll_mc.scrollBttn._y<scroll_mc.scrollBttn.originY) {
			scroll_mc.scrollBttn._y = scroll_mc.scrollBttn.originY;
		} else if (scroll_mc.scrollBttn._y>scroll_mc.scrollBttn.originY+scroll_mc.scrollBar._height-scroll_mc.scrollBttn._height) {
			scroll_mc.scrollBttn._y = scroll_mc.scrollBttn.originY+scroll_mc.scrollBar._height-scroll_mc.scrollBttn._height;
		}
	}
	if (scroll_mc.scrollBttn._y>scroll_mc.scrollBttn.maxY) {
		scroll_mc.scrollBttn._y = scroll_mc.scrollBttn.maxY;
	}
};
Mouse.addListener(mouseListener);
//

но скатина не работает! вот и вопрос почему? Могу выложить файлы если это поможет?ну заранее спасибо!

var mouseListener:Object = new Object();
Mouse.addListener(_root);
_root.onMouseWheel = function(delta:Number, object:MovieClip):Void {
mapp._yscale += delta;
mapp._xscale += delta;
};
