在javascript中填充六边形区域

在javascript中填充六边形区域,javascript,processing,maze,p5.js,Javascript,Processing,Maze,P5.js,我正试图用维基百科链接中提到的算法构建一个迷宫生成器: 因为我试图练习机器学习,所以我想使用深度优先搜索算法,到目前为止,我的代码运行良好: mazegenerator.js: var cells = []; var sideofCell = 40; var cellh = 40*Math.sin(1.04719755); var cellx = 20; var past = new Array(); var current; function setup(){ createCanvas(140

函数设置(){
createCanvas(1400900);
对于(var i=0;i,
beginShape()
vertex()
函数允许您绘制任意形状,包括六边形

下面是一个小例子:

函数设置(){
createCanvas(200200);
}
函数绘图(){
背景(64);
填充(255);
beginShape();
顶点(200100);
顶点(150186);
顶点(50186);
顶点(0,100);
顶点(50,13);
顶点(150,13);
顶点(200100);
endShape();
}
使用
beginShape()
vertex()
函数可以绘制任意形状,包括六边形

下面是一个小例子:

函数设置(){
createCanvas(200200);
}
函数绘图(){
背景(64);
填充(255);
beginShape();
顶点(200100);
顶点(150186);
顶点(50186);
顶点(0,100);
顶点(50,13);
顶点(150,13);
顶点(200100);
endShape();
