首先在game目录下创建site文件夹，用来存放战域相关代码：
这里思考下如何创建战域，我的想法是添加一个平面，将己方战域和对方战域都添加进这个平面中，所以首先我们先添加一个战域plane，site/index.vue代码如下：
<!-- 场地 -->
<template>
<P1 ref="p1Ref"/>
<!-- <P2 ref="p2Ref"/> -->
</template>
<script setup lang="ts">
import { reactive, ref, onMounted, onBeforeUnmount, watch, defineComponent, getCurrentInstance, nextTick } from 'vue'
import { transPos } from "@/utils/common.ts"
import P1 from "./p1.vue"
// import P2 from "./p2.vue"
// 引入threejs变量
const {proxy} = getCurrentInstance()
const THREE = proxy['THREE']
const scene = proxy['scene']
const camera = proxy['camera']
const renderer = proxy['renderer']
const TWEEN = proxy['TWEEN']
const raycaster = new THREE.Raycaster();
const p1Ref = ref()
// const p2Ref = ref()
onMounted(() => {
// init()
})
const init = async () => {
await addSitePlane()
// setSite()
p1Ref.value.init()
// p2Ref.value.init()
}
// 添加战域plane
const addSitePlane = () => {
return new Promise((resolve, reject) => {
// 设置战域大小和位置
let plane = scene.getObjectByName("地面")
let point = transPos(0, 0) // 战域起始位置的屏幕坐标
//
raycaster.setFromCamera( point, camera );
const intersects = raycaster.intersectObject( plane );
if (intersects.length > 0) {
let point = intersects[0].point
// 进行裁剪
// let x = Math.abs(point.x) * 2 - 2.4
// let y = Math.abs(point.z) * 2 - 4
let x = Math.abs(point.x) * 2
let y = Math.abs(point.z) * 2
const geometry = new THREE.PlaneGeometry( x, y );
geometry.center()
const material = new THREE.MeshBasicMaterial({
color: new THREE.Color("gray"),
side: THREE.FrontSide,
alphaHash: true,
// alphaTest: 0,
opacity: 0
});
const site = new THREE.Mesh( geometry, material );
site.name = "战域"
site.rotateX(-90 * (Math.PI / 180)) // 弧度
site.userData["width"] = x
site.userData["height"] = y
scene.add(site)
resolve(true)
}
})
}
defineExpose({
init,
})
</script>
<style lang="scss" scoped>
</style>这里计算出了平面的长和宽，将长宽数据存放进site的userData中，这个长和宽可以用来帮助我们后续绘制格子的时候做位置计算。然后我们在site/p1.vue中开始绘制己方战域：
1.绘制一个线框格子，格子Box的大小和卡牌设置成一样，如果在屏幕中看着比较大也可以通过scale进行适当的缩放：
// 创建线框网格
const createWireframe = () => {
const geometry = new THREE.BoxGeometry( 1, 0, 1.4 );
const edges = new THREE.EdgesGeometry( geometry );
const line = new THREE.LineSegments( edges, new THREE.LineBasicMaterial( { color: 0xffffff } ) );
line.rotateX(-90 * (Math.PI / 180)) // 弧度
line.scale.set(0.8, 0.8, 0.8) // 缩放
return line
}2.我们可以按照自己的想法绘制游戏中有几个格子，这里我设计的是前5个格子（包括一个场地格子和一个墓地格子），后三个格子，site/p1.vue相关代码如下：
// 初始化己方战域
const init = () => {
let sitePlane = scene.getObjectByName("战域")
let planeWidth = sitePlane.userData.width
let spaceX = (planeWidth - 5) / 4 // 设计一行有5个格子
// console.log(123, spaceX)
for (let i=0; i<5; i++) {
let mesh = createWireframe()
if (i == 0) {
mesh.name = "场地"
} else if (i == 1) {
mesh.name = "己方场地1"
} else if (i == 2) {
mesh.name = "己方场地2"
} else if (i == 3) {
mesh.name = "己方场地3"
} else if (i == 4) {
mesh.name = "墓地"
}
if (i == 0 || i == 4) {
mesh.position.set(-planeWidth/2 + 0.5, -0.65, 0)
} else {
mesh.position.set(-planeWidth/2 + 0.5, -0.7, 0)
}
mesh.translateX(spaceX * i + i)
sitePlane.add(mesh)
}
for (let i=0; i<5; i++) {
if (i > 0 && i < 4) {
let mesh = createWireframe()
if (i == 1) {
mesh.name = "己方场地4"
} else if (i == 2) {
mesh.name = "己方场地5"
} else if (i == 3) {
mesh.name = "己方场地6"
}
mesh.position.set(-planeWidth/2 + 0.5, -2.2, 0)
mesh.translateX(spaceX * i + i)
sitePlane.add(mesh)
}
}
}这里我为每个格子添加了name，方便后续卡牌上场，进墓等操作逻辑。
页面效果如下：
