父函数中的一个函数不会异步运行

如何解决父函数中的一个函数不会异步运行

很抱歉无法提供有效的代码，但愚蠢的是，我有一个函数调用世界，还有两次调用外部astar路径查找器脚本的函数。我一直在移动await的实例，然后几天又几天来解决，而我movePlayer(journeyPart2)等不及await movePlayer(journeyPart1)完成。我也看了无数关于诺言的视频，但看不到我要去哪里错了。我也尝试仅在for循环到达其最后一个实例时才返回某些东西，但这没有用。我真的希望对我要出错的人很明显。不幸的是，第二个movePlayer函数需要花费可变的时间才能完成，所以我不能单独使用设置的时间间隔来对第二个movePlayer函数进行排队。

我实际上不需要从movePlayer函数返回任何数据，但我知道至少必须返回诺言。如何使第二个movePlayer函数等待？

编辑：请注意，else if可以正常工作，因为movePlayer仅被调用一次。

function movePlayer(journey) {
  return new Promise((resolve,reject) => {
    for (let i = 0; i < journey.length; i++){
      (function(i){
        window.setTimeout(function(){
          let nextX = journey[i].y;//?SWITCHED X AND Y AS ASTAR SWITCHES IN GRAPH
          let nextY = journey[i].x;//?SWITCHED X AND Y AS ASTAR SWITCHES IN GRAPH
          let fromTop = (26 + (nextX * 16) + (nextY * 16)) + "px";
          let fromLeft = (576 + (nextX * 32) - (nextY * 32)) + "px";
          document.getElementById("playerLayer").style.left = fromLeft;
          document.getElementById("playerLayer").style.top = fromTop;
        },i * (900));
      }(i));
    }
  resolve("complete")
  reject("failure")
  })
}

function globalPathFindANDMove(cellNumEnd,levelNumEnd) {
  let cellNumStart = playerInfo.cellNow;
  let levelNumStart = playerInfo.levelNow;
  let j1Complete = false;
    if (levelNumStart != levelNumEnd) {
      (async function(){
        try {
          let journeyPart1 = await localPathFind(cellNumStart,undefined,levelNumStart)
          let journeyPart2 = await localPathFind(undefined,cellNumEnd,levelNumEnd)
          let useless = await movePlayer(journeyPart1)
          console.log(useless)
          movePlayer(journeyPart2)//this function won't wait until the function above completes
//------------------------------------------------------changePlayerLevel (levelNumEnd);-----------------------CREATE LATER
        } catch (err) {
        }
      })();
    } else if (levelNumStart == levelNumEnd) {
      let journey = localPathFind(cellNumStart,levelNumEnd);
      movePlayer(journey);
  }  
}

解决方法

很难确定要在代码中做什么，但是我认为您只想等setTimeout部分运行后再解决：

function movePlayer(journey) {
  return new Promise((resolve,reject) => {
    for (let i = 0; i < journey.length; i++){
      (function(i){
        window.setTimeout(function(){
          let nextX = journey[i].y;//?SWITCHED X AND Y AS ASTAR SWITCHES IN GRAPH
          let nextY = journey[i].x;//?SWITCHED X AND Y AS ASTAR SWITCHES IN GRAPH
          let fromTop = (26 + (nextX * 16) + (nextY * 16)) + "px";
          let fromLeft = (576 + (nextX * 32) - (nextY * 32)) + "px";
          document.getElementById("playerLayer").style.left = fromLeft;
          document.getElementById("playerLayer").style.top = fromTop;
          if (i === journey.length - 1) {
              resolve("complete")
          }
        },i * (900));
      }(i));
    }
  })
}
