这个类文件跟Tween放在同一个目录下
这样就可以用Tween类来变化组件
就不用本人去写渐变函数了
用法:
与Tween差不多
如:
import mx.transitions.fanflash_Tween;
import mx.transitions.easing.Strong;
var fan = new fanflash_Tween(a, test, Strong.easeOut, 260, 100, 6, true);
function test(t:Number) {
_root.txt_txt.setSize(_root.txt_txt._width, t);
}
要先定义一个函数,有一个参数,这个参数就是用来变化的(当第二个参数为函数时,第一个参数就会没用,所以乱写都可以),刚刚由于需要而改的,不足之处一定有,凑和着用吧
如果第二个参数是字符的话,那就跟平常的TWEEN类一样了
