Example
MScriptContext is used to manage script functions virtually. Custom functions can be declared during a plugin initialization in c++, you can send values to the script context using pushInt, pushString, etc,and get arguments from a script call using getInteger, getString, etc.
#include <MEngine.h>
#include "MyPlugin.h"
int myFunction(void)
{
MEngine * engine = MEngine::getInstance();
MScriptContext * script = engine->getScriptContext();
script->pushString("Hello World !");
return 1; // return 1 because the function is sending 1 value to the context (use 0 for none, 2 for 2 values...)
}
void StartPlugin(void)
{
MEngine * engine = MEngine::getInstance();
MScriptContext* script = engine->getScriptContext();
script->addFunction("myFunction", myFunction);
}
In Lua the function will be used like this:
text = myFunction() -- "Hello World !"
