问题描述
所以我有一个图片,我想下拉页面.
So i have an image that i want to drop down the page.
如果用户点击一个按钮,图片将停止下拉页面.
Should the user click a button, the image will stop said dropping down the page.
我使用 eventListener 'complete' 样式来执行此操作...并且它以某种方式起作用.问题是下降是波涛汹涌的〜令人恼火.
I've used the eventListener 'complete' style to execute this... and it works, in a fashion. The problem is that the dropping down is choppy ~ irritatingly so.
钛是否有更有效的方式来制作某种形式的简单动画?
Is there a more efficient way for titanium to do some form of simple animation?
这是一个代码片段:
ballAnimation = Ti.UI.createAnimation({
top: ballDown.top + 0.01*heightOfScreen,
duration: someSpeedHere
}, function(){
if (hasBeenPressed){
return;
}
else if (!hasBeenPressed && ballAnimation.top > lowestPointForBall){
someFunctionHere(); //this isn't part of the problem.
}
}
);
ballAnimation.addEventListener('complete', function(){
if (hasBeenPressed){
return;
}
else if (!hasBeenPressed && ballAnimation.top > lowestPointForBall){
someFunctionHere(); //this isn't part of the problem.
} else {
ballAnimation.top = ballAnimation.top + 0.01*heightOfScreen;
ballDown.animate(ballAnimation);
}
});
ballDown.animate(ballAnimation);
推荐答案
对于动画,建议使用具有如下转换的 2D 矩阵:
For animations it is advised to use a 2D matrix with a translation like this:
var translation = Titanium.UI.create2DMatrix(), deltaX, deltaY; // set the deltaX and deltaY according
translation = translation.translate(deltaX, deltaY);
ballDown.animate({
transform : translation,
duration : someSpeedHere
});
