收集整理的這篇文章主要介紹了
3D迷宫（二）babylon.js
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
3D迷宮（二）babylon.js
續(xù)上一篇的文章。
前面說到迷宮的算法，地圖生成路線的代碼如下：
// 繪制 地圖 數(shù)據(jù)this.__proto__.MapDrawData = function(){this.mapDrawData = [];for(let x = 0; x <= mapSize; x++){for(let y = 0; y <= mapSize; y++){if(this.map[x][y] == mapInit){this.mapDrawData.push([[x,y],this.MapDataXY(x,y)]);}}}}//地圖 數(shù)據(jù) x y軸的走向this.__proto__.MapDataXY = function(x,y,n = -1){var list = [];this.map[x][y] = mapWall;if(n === -1){++y;n = 0;if(y < mapSize){list = this.JudgeGrid([[x,y]]);}if(list.length <= 0){n = 1;++x;--y;if(x > mapSize){--x;return [x,y];}list = this.JudgeGrid([[x,y]]);if(list.length <= 0){--x;return [x,y];}}}else{n === 0 ? ++y : ++x;if(x > mapSize){--x;return [x,y];}if(y > mapSize){--y;return [x,y];}list = this.JudgeGrid([[x,y]]);if(list.length <= 0){n === 0 ? --y : --x;return [x,y];}}list = this.MapDataXY(x,y,n);return list;}突然感覺還可以用更簡(jiǎn)單的方式來做，大學(xué)白上了。
3D迷宮代碼，如下:

歷史，先是了解到three.js 后面發(fā)現(xiàn) webGl 再發(fā)現(xiàn) babylon.js
本來是用three.js做的，但是不知道看了誰的文檔，說webGl是遠(yuǎn)古時(shí)期的投石索，three.js 是AK47，babylon.js 絕地武士的光劍。
然后我就用babylon.js了。
找工作咯，不然沒飯吃了
