编写一个俄罗斯方块

编写俄罗斯方块 思路。

1、创建容器数组，方块，

2、下落，左右移动，旋转，判断结束，消除。

定义一个20行10列的数组表示游戏区。初始这个数组里用0填充，1表示有一个方块，2表示该方块固定了，

然后随机出一个方块，操作左右转，触底变2后，再随机下一个方块，循环直到判定结束。

<template>
    <div>
        <div class="gamebox">

主要逻辑部分

import { ArrowLeftBold, Refresh, ArrowRightBold } from '@element-plus/icons-vue'
import { GameControl } from "./class/GameControl";
import { reactive  } from "vue";

const elsStore = reactive({
    els: new GameControl()
}) 
 
 


const rotateClick = () => {
    console.log("向右旋转");
    elsStore.els.rotate()
}
const leftClick = () => {
    elsStore.els.current_plate.position.x =
        (elsStore.els.current_plate.position.x > 0) ? elsStore.els.current_plate.position.x - 1 : 0
  
}
const rightClick = () => {
    elsStore.els.current_plate.position.x =
        (elsStore.els.current_plate.position.x + elsStore.els.current_plate.getPlateSize().width < 10)
            ? elsStore.els.current_plate.position.x + 1 : elsStore.els.current_plate.position.x

}
const downClick = () => {

    elsStore.els.current_plate.position.y += 1
}



const timers = () => {
    console.log("游戏循环开始");
    // 检查当前盘是否有重叠的，因为最后一步是让动块下降一格。
    // 因此，如果最后一步没有重叠，那么说明盘已经到底了，游戏结束
    // console.log('currentBox' + elsStore.els.current_plate.name, elsStore.els.current_plate.position.y);

    if (!elsStore.els.checkShowPlateIsOK()) {
        console.log("游戏结束");
        elsStore.els.started = false;
        return false
    }



    // 在Main盘面合法的情况下，需要检查即将触底或碰撞，就触发Lock更新
    if (elsStore.els.willPong()) {

        // console.log("====================Lock================");
        elsStore.els.lock_plate = elsStore.els.getShowPlate().join("@")
        // 消除
        elsStore.els.checkAndClear();
        // 负责下一块给当前动块，并随机一个下一块。
        elsStore.els.newCurrentPlate();
    } else {
        elsStore.els.current_plate.position.y += 1;
    }



    setTimeout(() => {
        if (elsStore.els.started) { timers(); }
    }, 500);

};


const gameStart = () => {

    console.log('游戏开始');
    if (elsStore.els.started) {
        return false;
    }
    elsStore.els.next_plate = elsStore.els.newRndPlate()

    timers();



}

        this.started = false
        this.score = 0
        this.init()
    }



    init() {
        // 初始化游戏 
        console.log("初始化游戏");

        // 显示一个等待方块，并等待用户按下开始按钮。 
    }

    // 生成一个随机盘子

    }

            const boxList = main[i].split(",")
            for (let j = 0; j < boxList.length; j++) {
                if (eval(boxList[j]) > 1) {
                    return false;
                }

最后是完整的源码下 http s://gitcode.net/ldy889/game-els 项目删掉了一些没用的东西，只保留了核心代码，需要自己去除一些错误。比如修改路径，无效的引入。
