篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了小5聊前端开发经典游戏俄罗斯方块（前端开发领域）相关的知识，希望对你有一定的参考价值。
一年一度的博客之星来了，在此通过前端开发方式实现经典游戏俄罗斯方块
俄罗斯方块游戏，大家都玩过，今天就用自己熟悉的jQuery来实现TA
可提供完整源码，如果小伙伴们需要的话（步骤里其实也是完整的源码了）
一、功能分析
1、设置一个高宽度范围
长=20格，宽=10格（标准设置）
2、方块类型
- 七种类型
O形、I形、S形、Z形、L形、J形、T形
不管是什么形状，都是由4个小格子拼接而成
- O形
一种旋转形态
- I形、S形、Z形
两种形态，就是两种旋转类型
- L形、J形、T形
四种形态，就是四个旋转方向，上右下左
3、控制方块方向
可以使用键盘的左右下来控制方块的移动方向
4、定时器
通过定时器控制方块向下移动，可以先设置每一秒种向下移动一个单位，比如设置好的30px一个移动单位
5、边界判断
主要有三个边界判断
1）到达底部边界判断
2）到达左右两边边界判断
3）到达某一方块上方边界判断
6、方块旋转
通过left和top移动标志，保持left和top值不变，根据每个形态的每个小方块进行公式计算即可
7、方块消除分析
每个格子都是独立，移动到一定位置后，如果10个小方块都是同在一行，那么就直接对当前行的小方块进行移除即可
二、实现流程
1、页面范围设计
长宽2:1，div高宽设计为600px:300px
- 代码
<div style="background:#099dff;position:absolute;top:150px;left:50%;height:600px;width:300px;box-shadow:0 0 13px #ccc;margin-left:-150px;">
<!--游戏面板-->
<div class="playDiv" style="background: #099dff; position: relative; height: 600px; width: 300px;">
</div>
<!--开始按钮-->
<div class="btnStartDiv" style="position:absolute;top:-45px;left:0px;width:60px;height:35px;line-height:35px;text-align:center;background:#099dff;color:#fff;cursor:pointer;">
<span>开始</span>
</div>
<!--测试-->
<div class="testDiv" style="position:absolute;top:0px;right:-150px;">
<div class="one" style="height:35px;line-height:35px;"></div>
<div class="two" style="height:35px;line-height:35px;"></div>
<div class="three" style="height:35px;line-height:35px;"></div>
</div>
</div>
<script type="text/template" id="shapeTemplate">
<div class="shapeDiv shapeMoveDiv" style="width: 30px;height: 30px;background: #3e3cd0;position:absolute;top:0px;left:0px;">
<div style="width:100%;height:100%;box-sizing:border-box;border:2px solid #000;"></div>
</div>
<div class="shapeDiv shapeMoveDiv" style="width: 30px;height: 30px;background: #3e3cd0;position:absolute;top:0px;left:0px;">
<div style="width:100%;height:100%;box-sizing:border-box;border:2px solid #000;"></div>
</div>
<div class="shapeDiv shapeMoveDiv" style="width: 30px;height: 30px;background: #3e3cd0;position:absolute;top:0px;left:0px;">
<div style="width:100%;height:100%;box-sizing:border-box;border:2px solid #000;"></div>
</div>
<div class="shapeDiv shapeMoveDiv" style="width: 30px;height: 30px;background: #3e3cd0;position:absolute;top:0px;left:0px;">
<div style="width:100%;height:100%;box-sizing:border-box;border:2px solid #000;"></div>
</div>
</script>2、方块形状设计
上一步骤设计了宽度为300px，那么一个小格子就是30px，并且每个形状都有四个方向的
1）O形
2）I形
3）S形
4）Z形
5）L形
6）J形
7）T形
3、全局参数设置
1）方块模板
模板里有4个小方块，然后根据随机以及公式对4个方块进行absolute相对定位，组成一个方块形状以及方块方向
<script type="text/template" id="shapeTemplate">
<div class="shapeDiv shapeMoveDiv" style="width: 30px;height: 30px;background: #3e3cd0;position:absolute;top:0px;left:0px;">
<div style="width:100%;height:100%;box-sizing:border-box;border:2px solid #000;"></div>
</div>
<div class="shapeDiv shapeMoveDiv" style="width: 30px;height: 30px;background: #3e3cd0;position:absolute;top:0px;left:0px;">
<div style="width:100%;height:100%;box-sizing:border-box;border:2px solid #000;"></div>
</div>
<div class="shapeDiv shapeMoveDiv" style="width: 30px;height: 30px;background: #3e3cd0;position:absolute;top:0px;left:0px;">
<div style="width:100%;height:100%;box-sizing:border-box;border:2px solid #000;"></div>
</div>
<div class="shapeDiv shapeMoveDiv" style="width: 30px;height: 30px;background: #3e3cd0;position:absolute;top:0px;left:0px;">
<div style="width:100%;height:100%;box-sizing:border-box;border:2px solid #000;"></div>
</div>
</script>2）全局变量如下
var shapeUnitPx = 30; //格子单元像素
var leftMaxValue = 30 * 10; //300px，小方块最大的移动宽度
var topMaxValue = 30 * 20; //600px，小方块最大的移动高度
var leftArr = [0, 0, 0, 0]; //单元格的left值（每个方块都有4个小方块）
var topArr = [0, 0, 0, 0]; //单元格的top值（每个方块都有4个小方块）
var nextIndex = 0; //下一个切换方向下标
var currentIndex = 0; //当前小方块下标
var moveLeft = 0; //方块移动的left倍数
var moveTop = 0; //方块移动的top倍数
var htmlTemplate = $("#shapeTemplate").html(); //单元格模板
moveLeft = 5; //每个小方块的left值乘以5
moveTop = -2; //每个小方块的top值乘以-24、开始游戏按钮
1）点击开始游戏，默认方块的初始位置为left值的5倍，top的-2倍
2）随机从19种方块里获得1个方块
3）将随机得到的方块下标保存到全局当前方块下标里
4）调用创建方块方法或者移动方块方法
5）同时开启定时器，设置初始状态每隔1秒向下移动一个单元
//===开始===
$(".btnStartDiv").click(function ()
moveLeft = 5;
moveTop = -2;
var shapeIndex = Math.ceil(Math.random() * 19); //1~19随机出现数字
currentIndex = shapeIndex;
createShapeOrChangeHtml(shapeIndex);
moveTime = setInterval(autoMoveShape, 1 * 1000); //开启定时器
);5、创建方块或移动方块
1）根据方块下标，定位到不同的小方块的left和top值计算公式里
2）设置好方块的4个小方块的left和top值后，即可追加方块到游戏面板里
3）或者修改方块在面板的移动位置
//===生成方块形状===
function createShapeOrChangeHtml(shapeIndex)
//方块形状格子叠加原则：从下到上，从左到右
//这个规则的目的：为消除方块作为基础条件
//公式创建
if (shapeIndex == 1) //O
nextIndex = 1;

);
//===/方块是否可移动判断===
6、方块是否可移动判断
1）设置一个全局变量，保存已经在游戏面板占据空间的小方块的坐标
2）首先对方块进行右边界的判断，如果方块有一个小方块的left值大于等于了游戏面板的最大宽度，那么就停止向右边移动
3）到达底部判断，如果方块有一个小方块的top值超过了游戏面板的最大宽度，那么就停止向下移动，并移除当前方块移动标志的class值
4）如果游戏面板已经有方块存在，那么根据前面已经保存好的方块坐标来判断，如果存在相同坐标，那么停止方块移动，并将当前方块的坐标保存到全局变量里
5）如果通过上面步骤都不满足，那么就是可以移动，否则就进行下一步操作
6）如果方块触发了停止，那么就停止定时器向下移动方法
7）如果当前停止移动的方块的top值有出现负数，那么就结束游戏
//===判断是否可以移动===
var havePositionArr = [];
function IsMove(call)
var flag = 1;
//判断右边边界
for (var i = 0; i < leftArr.length; i++)
var _v = leftArr[i];
if (_v >= leftMaxValue)
flag = 0;
moveLeft -= 1;
if (!flag)
return;
//到达了底部，不可再移动
for (var i = 0; i < leftArr.length; i++)
var _v = topArr[i];
if (_v >= topMaxValue)
flag = 0;
//再判断是否存在的单元格
if (havePositionArr.length > 0)
for (var i = 0; i < leftArr.length; i++)
var currentPosition = leftArr[i] + "," + topArr[i];
for (var j = 0; j < havePositionArr.length; j++)
var havaPosition = havePositionArr[j];
if (currentPosition == havaPosition)
flag = 0;
//判断
if (flag) //可以移动方块
call();
else //停止移动方块
//===先停止定时器===
clearInterval(moveTime);
//===移除移动标志class===
var isFinal = 0;
for (var i = 0; i < $(".shapeMoveDiv").length; i++)
havePositionArr.push($(".shapeMoveDiv").eq(i).css("left").replace("px", "") + "," + $(".shapeMoveDiv").eq(i).css("top").replace("px", ""));
if (parseInt($(".shapeMoveDiv").eq(i).css("top").replace("px", "")) < 0)
isFinal = 1;
$(".shapeMoveDiv").removeClass("shapeMoveDiv");
if (isFinal)
alert("游戏结束！");
return;
//===/移除移动标志class===
//===再检查是否有可移除的方块==
checkRemoveFun();
7、检查是否有方块可消除
判断的原则
1）通过每个小方块的top值为分组，如果top值相同，且达到10个方块，那么说明是同一行，即可移除方块
2）移除方块后，再根据移除后的方块的top值来判断，小于这个top的上面的所有小方块就需要增加top值往下叠加
3）最后就是触发点击开始按钮，即可下一个方块
//===分段判断===
function checkRemoveFun()
//检查是否可以消除了
var length = $(".shapeDiv").length;
var tempArr = [];
var flag = '';
var currentTop = '';
for (var n = 0; n < length; n++)
currentTop = $(".shapeDiv").eq(n).css("top");
if (tempArr.length <= 0)
flag += currentTop + "|";
tempArr.push( key: currentTop, value: 1 );
else
if (flag.indexOf(currentTop) < 0)
flag += currentTop + "|";
tempArr.push( key: currentTop, value: 1 );
else
for (var i = 0; i < tempArr.length; i++)
if (tempArr[i]['key'] == currentTop)
var _vvv = parseInt(tempArr[i]['value']) + 1;
tempArr[i]['value'] = _vvv;
//循环移除10个单元格
var removeTop = '';
var removeRow = 0;
for (var i = 0; i < tempArr.length; i++)
if (parseInt(tempArr[i]['value']) >= 10)
removeTop = tempArr[i]['key'];
//先消除完再移动
for (var c = 0; c < 10; c++)
for (var n = 0; n < length; n++)
currentTop = $(".shapeDiv").eq(n).css("top");
if (currentTop == removeTop)
$(".shapeDiv").eq(n).remove();
removeRow += 1;
//上一层的top值向下
for (var n = 0; n < $(".shapeDiv").length; n++)
currentTop = $(".shapeDiv").eq(n).css("top");
if (parseInt(currentTop.replace("px", "")) < parseInt(removeTop.replace("px", "")))
$(".shapeDiv").eq(n).css("top", (parseInt(currentTop.replace("px", "")) + shapeUnitPx * removeRow) + "px");
//再循环保存现有的单元格
if (removeTop != '')
havePositionArr = [];
for (var i = 0; i < $(".shapeDiv").length; i++)
havePositionArr.push($(".shapeDiv").eq(i).css("left").replace("px", "") + "," + $(".shapeDiv").eq(i).css("top").replace("px", ""));
$(".btnStartDiv").trigger('click'); //触发开始，下一个方块
8、到此游戏基础逻辑完成
1）方块随机出现
2）定时器自动将方块往下移动
3）边界判断
4）方块停止判断
5）方块消除判断
9、后续可在基础逻辑上发挥了
1）消除后，增加分数
2）方块动态变化颜色
3）加上消除方块的音效
4）加上背景音乐
5）更换背景皮肤等等可任意发挥的功能
总结
这里提供的是一个开发思路和方向，方法和算法不一定是最佳的，我相信大家通过自己的方式也能快速开发出来
