根据上一篇所讲. 现在我们如何在外部生成一张地图.
一.
首先GetMapInfo.
从worldmapareadbc 获得
ID 以及mapName
GetNumberOfDetailTiles() 获取大地图的tile数量? 游戏内能直接获取, 游戏外部如何获取?
二.
从worldmapoverlay.dbc
同上面的ID, 获得当前地图overlays数量
以及他的材质名称, 高度 宽度 坐标位置.
地图 1002 * 668 ?
布局
256 256 256 256

特殊变量
WORLDMAP_POI_TEXTURE_WIDTH = 256;
WORLDMAP_COSMIC_ID = -1;
WORLDMAP_WORLD_ID = 0;
WORLDMAP_OUTLAND_ID = 3;
WORLDMAP_MAELSTROM_ID = 5;
MAELSTROM_ZONES_ID = { TheMaelstrom = 737, Deepholm = 640, Kezan = 605, TheLostIsles = 544 };

— Setup the overlays
local textureCount = 0;
for i=1, GetNumMapOverlays() do
local textureName, textureWidth, textureHeight, offsetX, offsetY = GetMapOverlayInfo(i);
if ( textureName and textureName ~= “” ) then
local numTexturesWide = ceil(textureWidth/256);
local numTexturesTall = ceil(textureHeight/256);
local neededTextures = textureCount + (numTexturesWide * numTexturesTall);
if ( neededTextures > NUM_WORLDMAP_OVERLAYS ) then
for j=NUM_WORLDMAP_OVERLAYS+1, neededTextures do
WorldMapDetailFrame:CreateTexture(“WorldMapOverlay”..j, “ARTWORK”);
end
NUM_WORLDMAP_OVERLAYS = neededTextures;
end
local texturePixelWidth, textureFileWidth, texturePixelHeight, textureFileHeight;
for j=1, numTexturesTall do
if ( j < numTexturesTall ) then
texturePixelHeight = 256;
textureFileHeight = 256;
else
texturePixelHeight = mod(textureHeight, 256);
if ( texturePixelHeight == 0 ) then
texturePixelHeight = 256;
end
textureFileHeight = 16;
while(textureFileHeight < texturePixelHeight) do
textureFileHeight = textureFileHeight * 2;
end
end
for k=1, numTexturesWide do
textureCount = textureCount + 1;
local texture = _G["WorldMapOverlay"..textureCount];
if ( k < numTexturesWide ) then
texturePixelWidth = 256;
textureFileWidth = 256;
else
texturePixelWidth = mod(textureWidth, 256);
if ( texturePixelWidth == 0 ) then
texturePixelWidth = 256;
end
textureFileWidth = 16;
while(textureFileWidth < texturePixelWidth) do
textureFileWidth = textureFileWidth * 2;
end
end
texture:SetWidth(texturePixelWidth);
texture:SetHeight(texturePixelHeight);
texture:SetTexCoord(0, texturePixelWidth/textureFileWidth, 0, texturePixelHeight/textureFileHeight);
texture:SetPoint("TOPLEFT", offsetX + (256 * (k-1)), -(offsetY + (256 * (j - 1))));
texture:SetTexture(textureName..(((j - 1) * numTexturesWide) + k));
texture:Show();
end
end
end
end
for i=textureCount+1, NUM_WORLDMAP_OVERLAYS do
_G["WorldMapOverlay"..i]:Hide();
end
