在For循环中按顺序创建p5.js实例，但仅在前一个实例完成后创建

let p5Instances = [];

function setup() {
  createCanvas(400, 400);
  // 假设我们想要创建5个p5.js实例
  let numberOfInstances = 5;

  // 使用async函数来确保按顺序创建实例
  async function createInstancesSequentially() {
    for (let i = 0; i < numberOfInstances; i++) {
      let sketch = async function(p) {
        p.setup = function() {
          // 初始化代码
        };
        p.draw = function() {
          // 绘制代码
        };
      };
      let instance = await new Promise((resolve) => {
        let p5Instance = new p5(sketch, 'p5-instance-' + i);
        p5Instance.then((instance) => {
          resolve(instance);
        });
      });
      p5Instances.push(instance);
    }
  }

  // 开始创建实例
  createInstancesSequentially();
}
