Exposing Lua entities to the network

Now that we know how to handle network communication in C++, let's have a look at how we can expose Lua entities to the network.

Net.Expose

In order to define RMIs and server properties, we'll need to call Net.Expose from within the global scope of your .lua script:

Net.Expose({
  Class = MyEntity,
  ClientMethods = {
    ClRevive             = { RELIABLE_ORDERED, POST_ATTACH, ENTITYID, },
  },
  ServerMethods = {
    SvRequestRevive          = { RELIABLE_UNORDERED, POST_ATTACH, ENTITYID, },
  },
  ServerProperties = {
  },
});

The previous function will define the ClRevive and SvRequestRevive RMIs, which can be called by using three subtables that are automatically created for your entity:

• allClients
• otherClients
• server

Function implementation

The remote functions are defined within either the Client or Server subtables of your entity script, so that the networking system can quickly find them while avoiding name conflicts.

For example, see the following...
