嘿,有人可以告诉我如何拍摄僵尸向玩家形象移动的图片。 所以僵尸图像会以一定的速度向zs.png移动,也许可以增加健康,所以当僵尸触及玩家时,玩家会失去健康
此游戏适用于3ds浏览器,因此必须是javascript和html
此处还有指向Link
上运行该网页的链接并且有人可以给我完整的代码,因为我是javascript的新手。感谢
这是我到目前为止所做的。

答案 0 :(得分:0)
编辑:更新了几个代码块以使它们实际工作(!),添加了关于脚本放置位置的说明并包含了jsFiddle
编辑2:不要只放left:100;top:100;height:30;width:20;
因为它不是有效的CSS而且许多浏览器会阻塞它。在每个号码后添加px
代替left:100px;top:100px;height:30px;width:20px;
。
一项小小的研究有很长的路要走。
How to detect if two divs touch with jquery?
Binding arrow keys in JS/jQuery
<小时/> 您几乎肯定希望使用jQuery来处理您正在做的事情。
尝试以下内容:
$(document).ready(function(){
$(document).keydown(function(e){
var c = $("#character");
if (e.keyCode === 37) {
// left arrow pressed
c.css("left","-=10px"); // subtract 10px from the character's CSS 'left' property, although you probably want some system to add a limit to this value
}else if(e.keyCode === 38) {
// up arrow pressed
c.css("top","-=10px"); // subtract 10px from the character's CSS 'up' property
}else if(e.keyCode === 39) {
// right arrow pressed
c.css("left","+=10px"); // add 10px to the character's CSS 'left' property
}else if(e.keyCode === 40) {
// down arrow pressed
c.css("top","+=10px"); // add 10px to the character's CSS 'top' property
}
return false;
});
});
这允许使用箭头键移动角色。
使僵尸图像移动有点困难。首先,将以下div
标记添加到您的文档中:
<div id="zombie" style="position:absolute;top:10px;left:10px;"><img src="YOUR_ZOMBIE_IMAGE.gif" /></div>
然后,添加以下JavaScript 以上 $(document).ready(function(){
行:
var zombieFrequency = 1000; // how long (in milliseconds) it should take the zombie to move to the character's position
var easeType = "swing"; // change this to "linear" for a different kind of zombie animation
最后,将以下内容添加到$(document).ready(function(){
块中:
setInterval(function(){
var c = $("#character");
$("#zombie").animate({"left":c.css("left"),"top":c.css("top")},zombieFrequency,easeType);
},zombieFrequency);
这应该让僵尸每0.6秒(600毫秒= 0.6秒)移动到角色的位置,虽然我自己没有测试过。
或者,您可以考虑使用CSS过渡,但我怀疑它们在Nintendo 3DS上运行顺畅(甚至支持)。
另外,您不能将链接和内部脚本的链接放在同一个<script>
标记中,如下所示:
<script src="//ajax.googleapis.com/libs/jquery/1.10.2/jquery.min.js">
// some more scripting
</script>
它们必须是分开的,如下所示:
<script src="//ajax.googleapis.com/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
// some more scripting
</script>
另外,根据{{{},建议您决定使用 单引号'
或双引号"
3}}。大多数人都使用双引号。
