天堂增加新地圖不用改核心的java寫法!

增加新地圖不用改核心
核心版本: r375
http://l1j-tw-99nets.googlecode.com/svn/trunk/

先說明一下，目前太陽神V14版、l1j-tw-99nets 還沒有這個功能，新增地圖都需要改核心
TextMapReader.java
在 MAP_INFO 陣列增加 mapid 及 座標範圍，按照以下修改，mapids 資料表增加地圖，及黑盒子maps增加 *.txt，就不用改核心了。

修改1
l1j\server\server\datatables\MapsTable.java
1-1
在開頭 import 群中插入這4行
import java.io.IOException;
import l1j.server.server.model.map.L1Map;
import l1j.server.server.model.map.L1V1Map;
import l1j.server.server.model.map.TextMapReader;

1-2
在這一行
private final Map<Integer, MapData> _maps = Maps.newMap();
下面增加
private final Map<Integer, L1Map> _loadMaps = Maps.newMap();

1-3
在這一行
_maps.put(new Integer(mapId), data);
下面增加這一段
TextMapReader textRead = new TextMapReader();
int xSize = data.endX - data.startX + 1;
int ySize = data.endY - data.startY + 1;

try {
L1V1Map map = new L1V1Map((short) mapId, textRead.read(mapId,
xSize, ySize), data.startX,
data.startY,
data.isUnderwater,
data.markable,
data.teleportable,
data.escapable,
data.isUseResurrection,
data.isUsePainwand,
data.isEnabledDeathPenalty,
data.isTakePets,
data.isRecallPets,
data.isUsableItem,
data.isUsableSkill);

_loadMaps.put(mapId, map);
} catch (IOException e) {
_log.log(Level.SEVERE, e.getLocalizedMessage(), e);
}

修改2
l1j\server\server\model\map\TextMapReader.java
2-1

這是為達功能所以剪貼出來的，還不是最有效率的寫法，希望有大大可以加入討論研究。
如果大家覺得還不錯，也希望這個功能可以加到 [太陽神V15版]、[l1j-tw-99nets]內。
