Lua Quick Start Guide

Constructor

Lua Bridge only supports a single constructor. Overloaded constructors are not possible to declare with Lua Bridge. A constructor can be added with the addConstructor function. The function signature of the constructor must be specified as a template argument, since a class may have multiple overloaded constructors. The following code shows a C++ class with three constructors, but only the one that takes three floats is exposed to Lua:

class Vec3 {  public:    Vec3();    Vec3(const Vec3& other);    Vec3(float x, float y, float z);}getGlobalNamespace(L)    .beginNamespace("Math")      .beginClass<Vec3>("Vec3")        .addConstructor<void (*) (float, float, float)>()      .endClass()    .endNamespace();
