使用p5.js制作极简人物动画

没有特别的技巧，只是不断尝试坐标，使用绘制直线和绘制弧线的函数尝试

然后，人物说话的动画是用随机数和其他几个嘴型制作的三帧动画

var Vector2=function(xValue,yValue){
  this.x=xValue;
  this.y=yValue;
}

var Vector3=function(xValue,yValue,zValue){
  this.x=xValue;
  this.y=yValue;
  this.z=zValue;
}
function Line(start,size){
line(start.x,start.y,start.x+size.x,start.y+size.y);
}

function setup() {
  createCanvas(600, 400);
  fd=0;
}

function draw() {
  background(255);
  noFill();
  strokeWeight(2);

  DrawOthers();
  
  DrawFancyFace();


  

  

  if(mouseIsPressed){
    console.log(mouseX,mouseY);
  }
  
}
