我需要使用库“Simple Lua Binder”存储一个Lua函数
typedef ? TLuaFunction;
class Foo
{
public:
void SetCallback( TLuaFunction f )
{
mCallback = f;
}
void ExecuteCallback()
{
f(); // Calls Lua function
}
private:
TLuaFunction mCallback;
};
// Manager initialization
SLB::Manager scriptManager;
// SetCallback registration into lua
SLB::Class<Foo>( "Foo", &scriptManager )
.constructor()
.set( "SetCallback", &Foo::SetCallback )
.set( "ExecuteCallback", &Foo::ExecuteCallback )
;
char* luaCode =
"SLB.using( SLB )\n"
"o = Foo()\n"
"o:SetCallback( function() \n"
" print( 'Callback executed' ) \n"
" end \n"
") \n"
"o:ExecuteCallback() \n";
SLB::Script script( &scriptManager );
script.doString( luaCode );
// The result is
> "Callback executed"
我不知道 SLB 库中是否有可以代替的类型?(见第一行代码)。
或者,如果我必须做不同的事情。
