Time for action - writing a new scriptbind function in C++

In order to be able to execute C++ code from Lua, we need to write a new, so-called Scriptbind function. Scriptbind functions are functions that are exposed to Lua, which means that this C++ function can be called from our Lua script code.

1. Open the ScriptBind_Actor.h file. You will find all actor-related functions, which are accessible in Lua, as seen in the following screenshot:

   

2. If you scroll down, you can simply add a new function there.

3. So, let's add a new function and name it TeleportTo. Search for SetSearchBeam (which is the last Scriptbind function in this file), and add your new function right under it in the ScriptBind_Actor.h file:

     //teleport the actor to targetPos
     virtual int TeleportTo(IFunctionHandler* pH, Vec3 targetPos);

   

   Note

   A Scriptbind function always returns an int (number) and gets an IFunctionHandler *pH as the first argument. Each following argument can be user defined. You can add as many arguments as you want...
