Since my game, which I'd really like to be Mono-usable, does not seem to run under Linux because LuaInterface is being a jerk (see the the relevant SO thread for more on that), I've decided to do what's suggested there. I wrote my own Lua511.LuaDLL class to reflect the one used by LuaInterface, replacing every single public function with...
I'am trying to return a string from a function but it doesn't compile. When I replace the std::string& type with int& it compiles, however I want to return additionally to the boolean a std::string how do I do this? bool luacw_getElementContent( std::string name, std::string& content, bool fromBeginning ) { content = "test"; retur...
I have an application that uses lua files for some of its more obscure configuration options. As such it mostly contains calls into the app to create things and alter properties; most C functions don't have a return value but some do. I now have a need to read these same configuration files into a different application, and perform sig...
I want to create a table like myTable = { [0] = { ["a"] = 4, ["b"] = 2 }, [1] = { ["a"] = 13, ["b"] = 37 } } using the C API? My current approach is lua_createtable(L, 0, 2); int c = lua_gettop(L); lua_pushstring(L, "a"); lua_pushnumber(L, 4); lua_settable(L, c); lua_pushstring(L, "b"); lua_pushnumber(L, 2); lua_settable(L, ...
I downloaded Eclipse Classic off of the Eclipse website then the Lua Eclipse IDE plugin. I followed the install instructions but Eclipse doesn't seem to recognize or be able to understand lua files. Can someone help? ...
I want to define a behavior on Javascript objects that kicks in when the referenced attribute/method doesn't exist. In Lua you can do this with metatables and the __index & __newindex methods. --Lua code o = setmetatable({},{__index=function(self,key) print("tried to undefined key",key) return nil end }) So I'm wondering if there...
Not really know how to ask so bare with me please :) #1 Lua: local test = Test(); #2 C: //creating "lua's test" luaL_newmetatable(L, "someTable"); lua_userdata *userData = (lua_userdata *)lua_newuserdata(L, sizeof(lua_userdata)); luaL_getmetatable(L, "someTable"); lua_setmetatable(L, -2); #3 Lua: function test.newMethod() end ...
Hello all, I have currently run into an issue while toying with Lua and the alien module to use Win32 API and such from Lua scripts. So far I have only had a single issue with alien which is with the use of API that use certain structures such as CreateFontIndirect. For example: HFONT CreateFontIndirectA( const LOGFONT& lplf ); LOGF...
T = { {Name = "Mark", HP = 54, Breed = "Ghost"}, {Name = "Stan", HP = 24, Breed = "Zombie"}, {Name = "Juli", HP = 100, Breed = "Human"}}, Questions: How would I Print just the names? and How can I sort it by HP? ...
I am trying to sort but there is a nil. How can i get around this?

Want the function to sort the table by HP but if duplicate HPs then sorts by name. When i run this function it just groups the duplicate HPs together in no order by the name. T = { {Name = "Mark", HP = 54, Breed = "Ghost"}, {Name = "Stan", HP = 24, Breed = "Zombie"}, {Name = "Juli", HP = 100, Breed = "Human"}, { HP = 100, Breed = "Human...
Lets say I am running a script and the game client waits for the script to be finished before it updates. Can Lua do somthing of a 'timeout'? Like, can i set a priority on the update so it leaves the script to do the update and then after words could it go back to where it was in the script? ...
I have a table that has multiple functions in it. I'm trying to write a single function that will go through and use all the functions by passing random information into it. Methods = {} insert functions into Methods Table function Methods:Multi() if #self > 0 then ......................... I'm guessing i need a loop t...
I Have stumbled on a weird behavior in Lua unpack function table1 = {true, nil, true, false, nil, true, nil} table2 = {true, false, nil, false, nil, true, nil} a1,b1,c1,d1,e1,f1,g1 = unpack( table1 ) print ("table1:",a1,b1,c1,d1,e1,f1,g1) a2,b2,c2,d2,e2,f2,g2 = unpack( table2 ) print ("table2:",a2,b2,c2,d2,e2,f2,g2) Output: table1:...

Is it possible to create a directory in lua ? If so, how ? ...
I need a game state object in lua(not c++ or tied to C++) to manage lights, cameras, objects, events from my C++ engine (the lua objects are seperate entities from c++, pretty much just standard lua tables). I am concerned about how the GC is going to act in removing these objects since they are going to be created and removed on the fly...

I have several Lua scripts that run experiences and output a lot of information, in text files and in the console. I'd like to add some colors in the console output, to make it more readable. I know that it's possible to color the output of bash scripts using the ANSI escape sequences. For example : $ echo -e "This is red->\e[00;31mRE...
I have lua embedded in my game engine and a directory structure of lua files, and i am starting to use lots of lua scripts. I want to use "requrie" to optimize module includes, but i am unsure how to set the CPATH and PATH values because i have lua embedded. How can I set this up? And also, since require looks for modules and not paths,...
