Written for CEGUI 0.3
Works with versions 0.3.x (obsolete)
Obsolete warning: This article has been written for an old version of CEGUI and likely doesn't apply to current stable!
This applies to the CEGUI 0.3.0 Release.
Enable logging
Lua scripts get a lot of bugs. Without logging, you will never know why your application simply quits without stepping through every line of code.
In CEGuiSample.cpp
bool CEGuiSample::initialise() { . . . default: // TODO: Throw exception or something! + return false; - break; } + CEGUI::Logger *logger = &CEGUI::Logger::getSingleton(); + logger->setLoggingLevel( CEGUI::Informative ); +#if defined( __WIN32__ ) || defined( _WIN32 ) + logger->setLogFilename( "C:\\Sample_FirstWindow.log", true ); +#elif defined(linux) + logger->setLogFilename( "~/Sample_FirstWindow.log", true ); +#else + logger->setLogFilename( "Sample_FirstWindow.log", true ); +#endif // execute the base application (which sets up the demo via 'this' and runs it. if (d_sampleApp->execute(this))
Create a Lua State
In Sample_FirstWindow.cpp
#include "CEGUI.h" + #include "../ScriptingModules/CEGUILua/LuaScriptModule/include/LuaScriptModule.h"
In Sample_FirstWindow.cpp
bool FirstWindowSample::initialiseSample() { using namespace CEGUI; + // create a lua_state by using [[User:Lindquist|Lindquist]]'s awesome LuaScriptModule + LuaScriptModule* lua = new LuaScriptModule(); + // create the CEGUI namespace in the Lua environment + lua->createBindings(); . . . // DefaultWindow which we will be using as the root of the displayed gui. root->addChildWindow(wnd); + // call a script from our the datafiles + lua->executeScriptFile("../datafiles/scripts/sample.lua", "test");
Create a Lua Script
In the Samples\datafiles directory Create a scripts directory
Create sample.lua
-- get the GUI sheet local sheet = CEGUI.WindowManager:getSingleton():getWindow("Root"); -- create a FrameWindow local fw = CEGUI.WindowManager:getSingleton():createWindow ("TaharezLook/FrameWindow","framewnd"); -- add it to the sheet sheet:addChildWindow(fw) -- set its size and position local sz = CEGUI.Size:new_local(0.5,0.5) local pos = CEGUI.Point:new_local(0.2,0.1) fw:setSize(sz) fw:setPosition(pos) fw:setText("Lua says Hello World!") -- disable user sizing fw:setProperty("SizingEnabled","False")
Running
Now just compile and run.
