我为Minecraft制作了一个允许Lua改装的mod。一切正常,但通常在MC中对方法的名称进行模糊处理。将普通函数名称重定向到模糊名称的最佳方法是什么?
例如,用户为右键单击打印hello world的块创建脚本:
function onActivated(world, x, y, z, player)
player:addChatMessage("hello world")
end
addChatMessage应该调用Java方法EntityPlayer.func_71035_c(String text)
答案 0 :(得分:1)
-- translation file (translation.txt)
func_70912_b,setTameSkin,2,
func_70913_u,getTameSkin,2,
func_70915_j,getShadingWhileShaking,2,Used when calculating the amount of shading to apply while the wolf is shaking.
func_70916_h,setAngry,2,Sets whether this wolf is angry.
-- obfuscated program (script.lua)
x:func_70913_u(y, z)
x:func_70915_j(y, z)
-- your preprocessor (preprocessor.lua)
local transl = {}
for line in io.lines'translation.txt' do
local obf, orig = line:match'^(.-),(.-),'
transl[obf] = orig
end
local script = assert(io.open('script.lua','rb')):read'*a'
local output = assert(io.open('script2.lua','wb'))
output:write((script:gsub('[%w_]+',transl)))
output:close()
-- preprocessor output (script2.lua)
x:getTameSkin(y, z)
x:getShadingWhileShaking(y, z)
编辑:
local obfuscations = {}
for line in io.lines'translation.txt' do
local obf, orig = line:match'^(.-),(.-),'
obfuscations[orig] = obf
end
local function get_obf_key_value(t, k, __index)
local value = __index and __index(t, k)
if value == nil and obfuscations[k] then
value = t[obfuscations[k]]
end
return value
end
local cache = {get_obf_key_value = true}
local function __index_constructor(__index)
if not __index then
return get_obf_key_value
end
local old__index = cache[__index]
if old__index then
return old__index == true and __index or old__index
else
local function new__index(t, k)
return get_obf_key_value(t, k, __index)
end
cache[__index] = new__index
cache[new__index] = true
return new__index
end
end
local obf_mt = {__index = get_obf_key_value}
local function correct_metatable(object)
local mt = getmetatable(object)
if mt == nil then
setmetatable(object, obf_mt)
else
local __index = mt.__index
if __index == nil or type(__index) == 'function' then
mt.__index = __index_constructor(__index)
else
correct_metatable(__index)
end
end
end
-- you should call correct_metatable(class_or_object_of_that_class)
-- at least once for every class
correct_metatable(wolf)
correct_metatable(goat)
correct_metatable(cabbage)
