我用actionscript做了一个测验。我已经开始在android（完整的新手）中进行测验，遵循动作脚本，以免让我的逻辑陷入困境。
我不知道如何处理 change_question 函数，尤其是第一块。以下。
function change_question(){
if(tick.visible){
right_answers++;
}
if(cross.visible){
wrong_answers++;
}
if(qno==questions.length){
gotoAndPlay(2);
}else{
tick.visible=false;
cross.visible=false;
rnd1=Math.ceil(Math.random()*3);
rnd2=Math.ceil(Math.random()*questions.length)-1;
q.text=questions[rnd2];
if(questions[rnd2]=="x"){
change_question();
}
questions[rnd2]="x";
enable_disable(1);
任何指导将不胜感激。提前致谢。
到目前为止，这是我的 android 代码！

这是我一直用来帮助处理逻辑的动作脚本模型。
