制作地图制作程序。 Field.as实例化_player。 Player.as将Kid_editorPanel添加到父级。当我单击编辑器面板中的按钮时，EditorPanel.as实例化一个名为tilepalette的动画片段。 Tilepalette拥有我希望能够通过单击我想要的图块来选择图块的所有图块集。
Field.as：
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.KeyboardEvent;
import flash.events.MouseEvent;
import flash.display.BitmapData;
import flash.display.Bitmap;
import flash.display.FrameLabel;
import flash.display.DisplayObjectContainer;
import flash.geom.Rectangle;
public class Field extends MovieClip{
private var player:Player;
private var sampleTile:Tile = new Tile();
private var _tilePalette:TilePalette;
private var _paletteArray:Array = [];
public function Field()
{
player = new Player();
player.x = 0;
player.y = 0;
addChild(player);
GetSampleTiles();
}
private function GetSampleTiles()
{
for (var i:int = 1; i <= sampleTile.totalFrames; i++)
{
var tileObj:Object = new Object();
sampleTile.gotoAndStop(i);
var graphicData:BitmapData = new BitmapData(32,32);
graphicData.draw(sampleTile);
tileObj.Name = sampleTile.currentFrameLabel;
tileObj.Graphic = graphicData;
tileObj.Frame = sampleTile.currentFrame;
Engine._tilesData.push(tileObj);
}
}
}
}
Player.as：
package {

public class Player extends MovieClip
{
private var _inp:Input = new Input();
private var _playerXindex:int = 0;
private var _playerYindex:int = 0;
private var _heldTile:Object;
private var _editorPanel:EditorPanel;
public function Player()
{
addChild(_inp);
addEventListener(Event.ENTER_FRAME, HandleKeys);
_heldTile = new Object();
}
private function HandleKeys(e:Event)
{
_playerXindex = x/32;
_playerYindex = y/32;

{
y += 32;
}
if(_inp.keyLeft)

}
if(_inp.keyRight)
{
x += 32;
}
if(_inp.keySpace)
{
try{DrawATile(_heldTile);}
catch(err:Error){trace("Bad or no graphic. Using this instead.");}
finally{DrawATile(Engine._tilesData[0]);}
}
if(_inp.keyA)
{
trace(Engine.tileObjIndex[_playerYindex][_playerXindex].Name);
}
if(_inp.keyB)

BuildStarterIndex();
SetHeldTile(Engine._tilesData[0]);
}
}
private function DrawATile(tileToDraw:Object)
{
if (Engine.tileObjIndex[_playerYindex][_playerXindex].Name.indexOf("Placeholder") >= 0)
{
trace("set");
var graphicData:BitmapData = new BitmapData(32,32);
graphicData.draw(tileToDraw.Graphic);
Engine.tileObjIndex[_playerYindex][_playerXindex].Name = tileToDraw.Name;
Engine.tileObjIndex[_playerYindex][_playerXindex].Graphic = tileToDraw.Graphic;
var newTile:Bitmap = new Bitmap(tileToDraw.Graphic);
newTile.x = x;
newTile.y = y;
parent.addChild(newTile);
}
}
private function BuildStarterIndex()
{
_editorPanel = new EditorPanel();
_editorPanel.x = 1;
_editorPanel.y = 544;
parent.addChild(_editorPanel);
for (var i:int = 0; i < 20; i++)

var graphicData:BitmapData = new BitmapData(32,32);
graphicData.draw(Engine._tilesData[0].Graphic);
tileObj.Name = "Placeholder" + "["+i+"]"+"["+u+"]";
tileObj.Graphic = graphicData;
tileObj.Frame = 0;
Engine.tileObjIndex[i].push(tileObj);
}
}
}
private function SetHeldTile(tiletoset:Object)
{
_heldTile.Name = tiletoset.Name;
_heldTile.Graphic = tiletoset.Graphic;
_heldTile.Frame = tiletoset.Frame;
_editorPanel.tileName.text = _heldTile.Name;
_editorPanel.tileFrame.text = _heldTile.Frame;
var heldTile:Bitmap = new Bitmap(_heldTile.Graphic);
heldTile.x = 30;
heldTile.y = 31;
_editorPanel.addChild(heldTile);
}
}
}
EditorPanel.as：
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.display.Bitmap;
import flash.events.Event;
public class EditorPanel extends MovieClip
{
public var _tilePalette:TilePalette;
private var _pArray:Array = [];
private var _mouseXi:int;
private var _mouseYi:int;
public var _tileGrabbed:Object;
public function EditorPanel()
{
btnpalette.addEventListener(MouseEvent.CLICK, BuildPalette);
}
private function UpdateMouse(e:Event)
{
_mouseXi = Math.floor(_tilePalette.mouseX/32);
_mouseYi = Math.floor(_tilePalette.mouseY/32);
}
private function BuildPalette(e:MouseEvent)
{
_tilePalette = new TilePalette();
_tilePalette.x = mouseX;
_tilePalette.y = mouseY-256;
addChild(_tilePalette);
var counter:int = 1;
for (var i:int = 0; i < 8; i++)
{
_pArray[i] = [];
for(var u:int = 0; u < 8; u++)
{
if(counter >= Engine._tilesData.length)
{
counter = 1;
}
var b:Bitmap = new Bitmap(Engine._tilesData[counter].Graphic);
b.x = 32 * u;
b.y = 32 * i;
_tilePalette.addChild(b);
_pArray[i].push(Engine._tilesData[counter]);
counter++;
}
}
_tilePalette.addEventListener(MouseEvent.MOUSE_MOVE, UpdateMouse);
_tilePalette.addEventListener(MouseEvent.CLICK, GrabATile);
}
private function GrabATile(e:MouseEvent)
{
return _pArray[_mouseXi][_mouseYi];
}
}
}
问题在于，当我执行GrabATile时，我不知道如何处理返回的Object引用。我想在Player函数SetHeldTile中使用该Object。
答案 0 :(得分：0)
所以这会使它工作，但我建议稍微重构一下代码。添加向父母添加内容的子项并不是最好的设计......在编辑器选择图块的地方还会有循环搜索，但是当玩家被告知有关时，播放器会将类似tileName的内容设置回编辑器。新瓷砖。这应该发生在进行磁贴选择等的编辑器中。
那就是说，根据您的流程，以下是如何使其发挥作用：
EditorPanel已经有一个属性_tileGrabbed。所以在你的GrabATile（）方法中只需设置
_tileGrabbed = _pArray[_mouseXi][_mouseYi];
然后在你的setHeldTile（）方法中......简单地说
_heldTile = _editorPanel._tileGrabbed.
现在，如果你需要GrabATile（）到TRIGGER setHeldTile（），处理它的最佳方法是使用一个事件。
// in EditorPanel
private function GrabATile(e:MouseEvent){
_tileGrabbed = _pArray[_mouseXi][_mouseYi];
dispatchEvent(new Event("tileChanged"));
}
// in Player
private function BuildStarterIndex(){
_editorPanel = new EditorPanel();
_editorPanel.addEventListener("tileChanged", setHeldTile);
// ... rest of code
}
private function SetHeldTile(event:Event){
_heldTile = _editorPanel._tileGrabbed;
// ... rest of code
}
