動畫停止動作3.0滴答

Question

所以，我有這個遊戲，我希望玩家移動，所以我使用一個滴答的方法，當關鍵是關閉它創建2個事件監聽器，一個keyup監聽器和一個tick。它的自我和刪除tick。tick包含運動和我推測動畫的地方。 這裏是我的代碼：

// For every frame // 
import flash.events.Event; 
import flash.events.TouchEvent; 
import flash.events.MouseEvent; 
import flash.events.KeyboardEvent; 
var gravity = 0.6; 
var floor = 410; 
jordan1.y = floor; 
jordan1.speedY = floor; 
jordan1.impulsion = 10; 
var onFloor:Boolean = false; 
var keyRight:Boolean = false; 
stage.addChild(jordan1); 
stage.addChild(leftwall1); 
stage.addChild(finish1); 
stage.addChildAt(abovedoor, 0); 
stage.addChild(left); 
stage.addChild(right); 
stage.addChild(jump); 
addEventListener(Event.ENTER_FRAME, enters); 
function enters(e:Event) { 
    jordan1.speedY += gravity; 
    jordan1.y += jordan1.speedY 
    if(jordan1.y > floor) { 
     jordan1.speedY = 0; 
     jordan1.y = floor; 
     onFloor = true; 
     if(keyRight == true) { 
      jordan1.gotoAndPlay(7); 
     } 
     if(keyRight == false) { 
     jordan1.gotoAndStop(1); 
     } 
    } 
} 

function stageup(e:MouseEvent) { 
    removeEventListener(Event.ENTER_FRAME,tickleft); 
    removeEventListener(Event.ENTER_FRAME,tickright); 
    removeEventListener(MouseEvent.MOUSE_UP, stageup); 
} 
stage.addEventListener(MouseEvent.MOUSE_DOWN, stagedown); 
function stagedown(e:MouseEvent) { 
    stage.addEventListener(MouseEvent.MOUSE_UP, stageup); 
} 



stage.addEventListener(KeyboardEvent.KEY_DOWN, jumpkey); 
function jumpkey(e:KeyboardEvent) { 
    if(e.keyCode == Keyboard.SPACE) { 
     if(onFloor == true) 
     { 
     jordan1.speedY=-jordan1.impulsion; 
     onFloor = false; 
     jordan1.gotoAndStop(2); 
     } 
     } 
    } 

stage.addEventListener(KeyboardEvent.KEY_DOWN, leftkey); 
function leftkey(e:KeyboardEvent) { 
if(e.keyCode == Keyboard.LEFT) { 
    addEventListener(Event.ENTER_FRAME, leftkeytick); 
    stage.addEventListener(KeyboardEvent.KEY_UP, leftkeydown); 



} 
} 
function leftkeydown(e:KeyboardEvent) { 
    removeEventListener(Event.ENTER_FRAME, leftkeytick); 
    stage.removeEventListener(KeyboardEvent.KEY_UP, leftkeydown); 

} 
function leftkeytick(e:Event) { 
    jordan1.x-=10; 
     if(onFloor == true) { 
    jordan1.gotoAndStop(3); 
    } 
    if(onFloor == false) { 
     jordan1.gotoAndStop(6); 
    } 

} 





stage.addEventListener(KeyboardEvent.KEY_DOWN, rightkey); 
function rightkey(e:KeyboardEvent) { 
if(e.keyCode == Keyboard.RIGHT) { 
    keyRight == true; 
    addEventListener(Event.ENTER_FRAME, rightkeytick); 
    stage.addEventListener(KeyboardEvent.KEY_UP, rightkeydown); 
} 
} 
function rightkeydown(e:KeyboardEvent) { 
    removeEventListener(Event.ENTER_FRAME, rightkeytick); 
    keyRight == false; 
    stage.removeEventListener(KeyboardEvent.KEY_UP, rightkeydown); 
} 
function rightkeytick(e:Event) { 
    jordan1.x+=10; 
    if(onFloor == true) { 
    jordan1.gotoAndPlay(7); 
    } 
    if(onFloor == false) { 
     jordan1.gotoAndStop(5); 
    } 
} 

// Just for this frame // 
leftwall1.addEventListener(Event.ENTER_FRAME, leftwall1hit); 
function leftwall1hit(e:Event) { 
    if(leftwall1.hitTestObject(jordan1)) { 
     jordan1.x +=10; 
    } 
} 

abovedoor.addEventListener(Event.ENTER_FRAME, abovedoorhit); 
function abovedoorhit(e:Event) { 
    if(abovedoor.hitTestObject(jordan1)) { 
     jordan1.x-=10; 
    } 
} 

jordan1.addEventListener(Event.ENTER_FRAME, finish1hit); 
function finish1hit(e:Event) { 
    if(jordan1.x > 960) { 
     gotoAndStop(67); 

    } 
} 

所以，當我測試它，並把它goestoandstops該keydown在7，而不是playing.Please幫助！謝謝！

您的goto不應該在您的勾號中，否則它們將在每幀中執行。這解釋了爲什麼它停留在框架7

而是把它們放在KEY_DOWN聽衆：

animated = false; 
stage.addEventListener(KeyboardEvent.KEY_DOWN, rightkey); 
function rightkey(e:KeyboardEvent) { 
    if(e.keyCode == Keyboard.RIGHT) { 
    if(onFloor == true && !animated) { 
     jordan1.gotoAndPlay(7); 
    } 
    if(onFloor == false && !animated) { 
     jordan1.gotoAndStop(5); 
    } 
    animated = true; 
    addEventListener(Event.ENTER_FRAME, rightkeytick); 
    stage.addEventListener(KeyboardEvent.KEY_UP, rightkeydown); 
    } 
} 
function rightkeydown(e:KeyboardEvent) { 
    animated = false; 
    removeEventListener(Event.ENTER_FRAME, rightkeytick); 
    stage.removeEventListener(KeyboardEvent.KEY_UP, rightkeydown); 
} 
function rightkeytick(e:Event) { 
    jordan1.x+=10; 
} 

但你不應該使用蜱功能與keydown事件。

KEY_DOWN在您按/ a鍵時調用每個幀。

如果你不能改變你的邏輯（這對你想達到的目標不好），你可以標記你的處理程序。 通過爲您正在監聽的每個鍵設置一個布爾值。 然後在你的滴答聲中，根據鍵被按下來做你需要做的事情。

keyRight = false; 
keyLeft = false; 
//... same for all your keys. 
// or you could store them in one object for a more dynamic solution. 

stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown); 
stage.addEventListener(KeyboardEvent.KEY_UP, keyUp); 
stage.addEventListener(Event.ENTER_FRAME,tick); 

function keyDown(e:KeyboardEvent){ 
    if(e.keyCode === Keyboard.RIGHT && !keyRight){ 
     keyRight = true; 
    } 
    else if(e.keyCode === Keyboard.LEFT && !keyLeft){ 
     keyLeft = true; 
    } 
    //... same for all your keys. 
} 

function keyUp(e:KeyboardEvent){ 
    if(e.keyCode === Keyboard.RIGHT){ 
     keyRight = false; 
    } 
    else if(e.keyCode === Keyboard.LEFT){ 
     keyLeft = false; 
    } 
    //... same for all your keys. 
} 

function tick(e:Event){ 
    if(keyRight) jordan1.x += 10; 
    if(keyLeft) jordan1.x -= 10; 
    //... etc for all your keys. 
} 

This other question覆蓋多個KEY_DOWN的主題非常好。
