废话不多说．上代码．

wd = [
    "6666666",
    "看着不错",
    "大家好",
    "主播声音挺好听啊",
    "不错，已回购",
    "已经拍了，速度发货啊",
    "已拍，主播速度发货",
    "确实可以，支持下",
    "送个小心心鼓励下",
    "味道不错，买过两次了"
];
ch = [ " "," "," "," ","　","~","!",",",".","。","，","～" ];
str = "说点什么";
str2 = "聊一聊";
a1 = textContains("说点什么").findOne(3000);
if( !a1 ){
    str = str2;
}
while( true ){
    a1 = textContains( str ).findOne(3000);
    if( a1 ){
        ab = a1.bounds();
        click( ab.centerX(), ab.centerY() );
        sleep(1000);
        a2 = textContains( str ).findOne(3000);
        if( a2 ){
            word = wd[ Math.round( Math.random()*wd.length ) ];//取话术
            word = word + ch[ Math.round(Math.random()*ch.length) ].repeat( Math.round(Math.random()*3) );
            a2.setText( word );
            sleep(2000);
            a3 = text("发送").findOne(3000);
            if( a3 ){
                ab3 = a3.bounds();
                click( ab3.centerX(), ab3.centerY() );
            }
        }
    }else{
        alert("中止，找不到元素！");
        break;
    }
    sleep( 10 * 1000 );
}

简单吧，

最下面 sleep( 10 * 1000 );  这里，是代表．１０秒钟．说一句话．
