我正在创建一个Flash网站，每次在页面上选择按钮时，都会更改下载链接到corepronding flash文件以供下载。奇怪的部分是我完成了这项工作，但经过一周的项目工作后，它就停止了，我不知道为什么输入会很好。
void Update () {
RaycastHit hit;
if (Physics.Raycast (eyes.transform.position,eyes.transform.forward, out hit,sightRange) && hit.collider.CompareTag ("Player")) {
transform.position += transform.forward * f_MoveSpeed * Time.deltaTime;
moveScript.enabled = false;
}
transform.position.z = 0; // or something along those lines, I don't remember the syntax exactly.
}

The main problem is function download(), you tried to get the element by Id "downLink", but there is no id assigned of that tag in HTML, so I add the id='downLink' to the tag now. The downlink works fine now.
Just a bit suggestions: as you already have the jQuery involved, you can probably use the jQuery selector when dealing with DOM. It will be more convenient also helps to keep the consistency of code.
$(document).ready(function () {
var links = [
'swfs/#1%20(Special%20Japanese%20Extended%20Dance%20Mix).swf',
'swfs/$D6.swf',
'swfs/(MAD)%20Huh.swf'
];
var displaytext = [
'#1 (Special Japanese Extended Dance Mix)',
'$D6',
'(MAD) Huh'
];
var c = 0;
var flashmovie, test, temp;
function init() {
flashmovie = document.getElementById('flashmovie');
document.getElementById('back').onclick = function () {
if (c == 0) {
c = links.length;
}
c--
displayFiles();
download();
}
document.getElementById('next').onclick = function () {
if (c == links.length - 1) {
c = -1;
}
c++;
displayFiles();
download();
}
document.getElementById('rand').onclick = function () {
temp = c;
while (c == temp) {
c = Math.floor(Math.random() * links.length);
}
displayFiles();
download();
}
// Scripts for the left and right arrow key functionality
document.addEventListener('keydown', function (e) {
if (e.which == 37) {
$("#back").click();
}
});
document.addEventListener('keydown', function (e) {
if (e.which === 39) {
$("#next").click();
}
});
}
function displayFiles() {
test = links[c].substring(links[c].lastIndexOf('.') + 1, links[c].length);
document.getElementById('title').innerHTML = displaytext[c];
flashmovie.innerHTML =
'<object type="application/x-shockwave-flash" data="' + links[c] + '">' +
'<param name="movie" value="' + links[c] + '">' +
'<\/object>';
}
function download() {
document.getElementById('downLink').setAttribute('href', links[c]);
document.getElementById('downLink').setAttribute('download', displaytext[c]);
}
window.addEventListener ?
window.addEventListener('load', init, false) :
window.attachEvent('onload', init);
