vue实现走棋盘

Vue 实现走棋盘功能

走棋盘功能通常用于棋盘类游戏或路径规划演示，以下是基于 Vue 3 的实现方案：

核心代码结构

<template>
  <div class="chessboard">
    <div v-for="(row, rowIndex) in board" :key="rowIndex" class="row">
      <div 
        v-for="(cell, colIndex) in row" 
        :key="colIndex"
        class="cell"
        :class="{ 
          'active': isActive(rowIndex, colIndex),
          'path': isInPath(rowIndex, colIndex)
        }"
        @click="moveTo(rowIndex, colIndex)"
      >
        {{ cell }}
      </div>
    </div>
  </div>
</template>

数据初始化

<script setup>
import { ref } from 'vue'

const boardSize = 8
const board = ref(Array(boardSize).fill().map(() => 
  Array(boardSize).fill(0)
))
const currentPosition = ref([0, 0])
const path = ref([])

// 初始化棋子位置
board.value[0][0] = '♟'
</script>

移动逻辑实现

const moveTo = (row, col) => {
  // 清除旧位置
  board.value[currentPosition.value[0]][currentPosition.value[1]] = 0

  // 更新新位置
  board.value[row][col] = '♟'
  currentPosition.value = [row, col]

  // 记录路径
  path.value.push([row, col])
}

const isActive = (row, col) => {
  return currentPosition.value[0] === row && 
         currentPosition.value[1] === col
}

const isInPath = (row, col) => {
  return path.value.some(pos => pos[0] === row && pos[1] === col)
}

样式设计

<style>
.chessboard {
  display: inline-block;
  border: 2px solid #333;
}

.row {
  display: flex;
}

.cell {
  width: 50px;
  height: 50px;
  border: 1px solid #ccc;
  display: flex;
  align-items: center;
  justify-content: center;
  background-color: #fff;
}

.cell:nth-child(odd) {
  background-color: #f0d9b5;
}

.cell:nth-child(even) {
  background-color: #b58863;
}

.active {
  background-color: #ff0000 !important;
}

.path {
  background-color: #aaffaa !important;
}
</style>

高级功能扩展

1. 移动限制

const isValidMove = (row, col) => {
  const [currentRow, currentCol] = currentPosition.value
  const rowDiff = Math.abs(row - currentRow)
  const colDiff = Math.abs(col - currentCol)

  // 例如只允许走日字形
  return (rowDiff === 2 && colDiff === 1) || 
         (rowDiff === 1 && colDiff === 2)
}

const moveTo = (row, col) => {
  if (!isValidMove(row, col)) return
  // ...原有移动逻辑
}

2. 动画效果

.cell {
  transition: background-color 0.3s ease;
}

.move-animation {
  animation: move 0.5s ease;
}

@keyframes move {
  from { transform: scale(0.8); }
  to { transform: scale(1); }
}

3. 键盘控制

onMounted(() => {
  window.addEventListener('keydown', handleKeyPress)
})

onUnmounted(() => {
  window.removeEventListener('keydown', handleKeyPress)
})

const handleKeyPress = (e) => {
  const [row, col] = currentPosition.value
  switch(e.key) {
    case 'ArrowUp': 
      if(row > 0) moveTo(row - 1, col)
      break
    case 'ArrowDown':
      if(row < boardSize - 1) moveTo(row + 1, col)
      break
    // 其他方向键处理...
  }
}

完整组件示例

<template>
  <div>
    <div class="chessboard">
      <!-- 棋盘渲染 -->
    </div>
    <div class="controls">
      <button @click="reset">重置</button>
      <span>当前位置: ({{ currentPosition[0] }}, {{ currentPosition[1] }})</span>
    </div>
  </div>
</template>

<script setup>
// 组合式API代码
const reset = () => {
  board.value = Array(boardSize).fill().map(() => 
    Array(boardSize).fill(0)
  )
  board.value[0][0] = '♟'
  currentPosition.value = [0, 0]
  path.value = []
}
</script>

以上实现可根据具体需求进行调整，如改变棋盘大小、棋子样式或移动规则等。对于更复杂的棋盘游戏，可以结合Vuex或Pinia进行状态管理。
