一.
在游戏中
mapFileName, textureHeight, textureWidth = GetMapInfo() 获取地图信息
然后获取到地图所在的图片路径
pathPrefix = “Interface\\WorldMap\\”..mapFileName..”\\”
例如荒芜之地
Badlands, 667, 768
二.
获取覆盖层数量
numOverlays = GetNumMapOverlays()
三
获取覆盖层信息
local texName, texWidth, texHeight, offsetX, offsetY = GetMapOverlayInfo(1-numOverlays)
四
拼接算法:
for texName, texID in pairs(overlayMap) do
local textureName = pathPrefix .. texName
local textureWidth, textureHeight, offsetX, offsetY = mod(texID, 2^10), mod(floor(texID / 2^10), 2^10), mod(floor(texID / 2^20), 2^10), floor(texID / 2^30)
local numTexturesWide = ceil(textureWidth / 256)
local numTexturesTall = ceil(textureHeight / 256)
local neededTextures = textureCount + (numTexturesWide * numTexturesTall)
if neededTextures > numOv then
for j = numOv + 1, neededTextures do
local texture = frame:CreateTexture(format(frameName, j), “ARTWORK”)
tinsert(textureCache, texture)
end
numOv = 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 = textureCache[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*scale)
texture:SetHeight(texturePixelHeight*scale)
texture:SetTexCoord(0, texturePixelWidth / textureFileWidth, 0, texturePixelHeight / textureFileHeight)
texture:ClearAllPoints()
texture:SetPoint("TOPLEFT", (offsetX + (256 * (k-1))) * scale, -(offsetY + (256 * (j - 1))) * scale)
texture:SetTexture(format(textureName.."%d", ((j - 1) * numTexturesWide) + k))if discoveredOverlays[texName] then
texture:SetVertexColor(1, 1, 1)
texture:SetAlpha(1 - (alphaMod or 0))
texture:SetDrawLayer("ARTWORK")
else
texture:SetVertexColor(r, g, b)
texture:SetAlpha(a * ( 1 - (alphaMod or 0)))
texture:SetDrawLayer("BORDER")
if db.debug then
DEFAULT_CHAT_FRAME:AddMessage(format("|cff33ff99Mapster|r: Subzone: %s in zone: %s", texName, mapFileName))
end
endtexture:Show()
end
end
end
