AS3在动画状态之间切换

  看到实际调用 animatePlayer 的代码会很有帮助;不管，下面是一个解决方案 .

  您可以在现有的 checkEveryFrame 中处理它，而不是依赖 MovieClip 进行动画制作，从而为您提供更精确的控制，以便在您需要时准确地更改动画状态 . 我为了演示而添加了 playerState 更改了UI点击 .

  尽管我可以告诉，这应该编译，但我没有其余的对象我无法尝试 .

  package {
      import flash.display.MovieClip;
      import flash.events.Event;
      import flash.events.MouseEvent;
      import fl.transitions.Tween;
      import fl.transitions.easing.*;
      import fl.transitions.TweenEvent;
  
      public class Main_Test_2 extends MovieClip 
          // variables
          private var cam:MovieClip = new MovieClip();
          private var player:Player = new Player();
          private var tweenSpeed:Number = 0.33;
          private var UI:UserInterface = new UserInterface();
  
          public function Main_Test_2():void {
              // initialize
              init();
          }
  
          public function init():void {   
              // initialize variables
              stage.addChild(cam);
              player.x = 200;
              player.y = playerTracks[0];
              cam.addChild(UI);
              cam.addChild(player);
  
              // add event listeners
              stage.addEventListener(Event.ENTER_FRAME, checkEveryFrame);
              UI.topButton.addEventListener(MouseEvent.CLICK, movePlayer);
              UI.centerButton.addEventListener(MouseEvent.CLICK, movePlayer);
              UI.bottomButton.addEventListener(MouseEvent.CLICK, movePlayer);
          }
  
          public function checkEveryFrame(event:Event):void {
              cam.x -= player.x - player.x;
              cam.y -= player.y - player.y;
              player.vx = player.x - player.prevX;
              player.vy = player.y - player.prevY;
              player.prevX = player.x;
              player.prevY = player.y;
  
              // Animation control
              var a:Array = animations[playerState]; // current animation set
              if (a.length == 2) {
                  var maxFrames:int = a[1] - a[0]; // Normalize the max value
                  var currentFrame:int = player.currentFrame - a[0]; // Normalize the current value
                  var nextFrame:int = normalizedCurrentFrame%maxFrames + a[0] // Modulus of max, and return to actual
                  player.gotoAndStop(nextFrame)
              }
          }
  
          private var playerState:String = "run";
          private var animations:Object = {
              "run":[1,60],
              "jump":[61],
              "jumpForward":[62]
          }
  
          private var playerTracks:Array = [610, 430, 250];
          private var playerLocIndex:int = 0;
  
          public function movePlayer(e:MouseEvent):void {
              // Based on the button clicked, increase/decrease/set the index of the destination
              switch (e.currentTarget) {
                  case UI.topButton:
                      playerState = "jump";
                      playerLocIndex++;
                      if (playerLocIndex > 2) { playerLocIndex = 2; } // Clamp upper
                      break;
                  case UI.centerButton:
                      playerState = "run";
                      playerLocIndex = 1;
                      break;
                  case UI.bottomButton:
                      playerState = "jumpForward";
                      playerLocIndex--;
                      if (playerLocIndex < 0) { playerLocIndex = 1; } // Clamp lower
                      break;
              }
  
              new Tween(player, "y", None.easeNone, player.y, playerTracks[playerLocIndex], tweenSpeed, true);
          }
      }
  }

  好的，我解决了这个问题 . 我不得不使用一个在计时器用完后执行其动作的计时器 . 我放置它和一行代码来改变每行代码中的状态与补间，因此动画将从运行转到跳转前进/后退动画，然后返回到计时器结束时运行 . 希望这有助于将来的其他人 .
