javascript如何制作游戏
首先,层我建议绝对定位,而且兼容不同的浏览器,scrollWidth,scrollTop,offsetWidth,offsetLeft,要运用自如,关键关键的是就是js自定义事件了,判断碰撞,边界碰撞,其它的都是小菜
相关问答
Q1: javascript小游戏问题
我只能提供思路,无法提供代码
一个div的任何一个点 ,在另一个div的四个点只能就算碰撞,比如
某个点,x 在另一个的 x1,x2 之间 y 在 y1,y2之间,则其一定在他的覆盖范围内
var top1 = document.getElementById("advLayer").offsetTop;
var top2 = document.getElementById("mydiv").offsetTop ;
var left1 = document.getElementById("advLayer").offsetLeft;
var left2 = document.getElementById("mydiv").offsetLeft;
var right1 = left1+document.getElementById("advLayer").offsetWidth;
var right2 = left2+document.getElementById("mydiv").offsetWidth;
var buttom1 = top1+document.getElementById("advLayer").offsetHeight;
var buttom2 = top2+document.getElementById("mydiv").offsetHeight;
if(top1top2 top1buttom2 left1left2 left1right2 ||
top1top2 top1buttom2 right1left2 right1right2 ||
buttom1top2 buttom1buttom2 left1left2 left1right2 ||
buttom1top2 buttom1buttom2 right1left2 right1right2
){
alert(1);
}
Q2: js简单回合制小游戏
var boss = [
{name:"校长",energy:10000},
{name:"教务主任",energy:8000},
{name:"系主任",energy:6000},
{name:"辅导员",energy:5000},
{name:"任课老师",energy:12000}
];
var hero = [
{name:"小张",energy:7000},
{name:"小王",energy:7000},
{name:"小强",energy:7000}
];
var n = prompt("选择一个英雄(0:小张,1:小王, 2:小强)","");
var h = hero[n];
var b = boss[Math.floor(Math.random() * boss.length)];
var i = 1;
while(true){
var hit = Math.floor(Math.random() * 800);
var bit = Math.floor(Math.random() * 1000);
h.energy -= bit;
b.energy -= hit;
if(b.energy 0 h.energy = 0){
alert("winner is boss");
break;
}else if(h.energy 0 b.energy = 0){
alert("winner is hero");
break;
}else if(h.energy = 0 b.energy = 0){
alert("DRAW GAME");
break;
}
alert("第" + i++ + "次回合, 英雄: " + h.name + "的能量剩余: " + h.energy + ", 怪兽"+ b.name +"的能量剩余: " + b.energy);
}
Q3: 一个javascript做的匹配游戏
alert('太遗憾了...');
//重置样式和选卡牌
currentPiece.className = '';
selectedPiece.className = '';
selectedPiece='';加一句代码
