lua-enet's Issues

Suggestions; adding the following to ENetHost references in Lua.

/* returns a string referencing the printable ip address of the current host /
static int host_get_address(lua_State l)
{
ENetHost *host = check_host(l, 1);
std::string address;
char buff[1024];
enet_address_get_host_ip(&host->address, buff, 1024);
address.clear();
address.append(buff);
lua_pushstring(l, address.c_str());
return 1;
}

/* and in function registry */

static const struct luaL_Reg enet_host_funcs [] =
{
{"service", host_service},
{"check_events", host_check_events},
{"compress_with_range_coder", host_compress_with_range_coder},
{"connect", host_connect},
{"flush", host_flush},
{"broadcast", host_broadcast},
{"channel_limit", host_channel_limit},
{"bandwidth_limit", host_bandwidth_limit},
{"total_sent_data", host_total_sent_data},
{"total_received_data", host_total_received_data},
{"service_time", host_service_time},
{"peer_count", host_peer_count},
{"get_peer", host_get_peer},
{"get_address", host_get_address},
{NULL, NULL}
};

If you find this useful, please add it. I'm currently using that add on function to run local server auto detection.

undefined symbol: luaL_register

when i was running the examples by using lua5.3,an error occurred:undefined symbol: luaL_register

Inconsistency between documentation and actual function name for host_socket_get_address()

The documentation explains the function host:get_socket_address(), however, the host_socket_get_address() is actually exported as socket_get_address, not get_socket_address.

MSVCR80.dll issue

I'm not sure what could be the problem, but i'm facing a weird issue with lua-enet. I'm adding multiplayer support to one old C++/SDL game and i was using luasockets before which was working just fine but i wanted to try lua-enet. I'm developing it using Wine on macOS because the game was only for Windows. It's working there using Wine just fine, both client and server connects, all works as it should but i have problems getting it to work on Windows natively.
I either get a MSVCR80.dll not found error there or if i put the C++ runtime dll next to lua5.1.dll and other stuff then it shows R6034 An application has made an attempt to load the C runtime library incorrectly. error.

I think that recompiling could help, but i wanted to ask first before compiling it myself.

require "enet" in lua5.1.exe works just fine and also client/server works that way

Build issues on ubuntu 12.04

I was trying to recreate an issue that @Bobbyjoness (Sorry bobbyjones) was having, and I was able to reproduce it.

I'm guessing that the enet deps on 12.04 are old, but perhaps there's a way to compensate?

This is from a pretty fresh ubuntu 12.04 vm instance;

error loading module enet

Hi. I'm getting the following error on Ubuntu 14.04 while trying to use enet in lua. It's installed using luarocks. The enet lib is installed from source, version 1.3.12.
What could be the problem?

lua5.1: error loading module 'enet' from file '/usr/local/lib/lua/5.1/enet.so':

stack traceback:

when i run the server/client demo i get this error

Peer round trip time information

The peer userdata seems to be lacking any way to access its information about round trip time. It would be useful to make this and other peer information available to Lua.

Undefined symbol: luaL_openlib

lua-enet on Windows

I've been attempting to get the bindings building and running on Windows, and haven't had much luck. I was able to get a .dll generated but upon attempting to run the echo server example Lua outputs the following:

-- server.lua
require "enet"
local host = enet.host_create"localhost:6789"
while true do
local event = host:service(100)
if event and event.type == "receive" then
print("Got message: ", event.data, event.peer)
event.peer:send(event.data)
end
end

lua: error loading module 'enet' from file '.\enet.dll':
The specified procedure could not be found.

stack traceback:
[C]: ?
[C]: in function 'require'
server\main.lua:2: in main chunk
[C]: ?

I imagine I'm doing something stupid while building. Are there any binaries existing for Windows that are confirmed working? I wasn't able to get it working through luarocks (couldn't find ENET_DIR despite it being set correctly) and had to manually build it within VS2005.

add some server send, broadcast, channel, flag for examples.

Trying to run some example for easy understand how this code work with Love2D and Lovr. Not much docs example or explain how it works.

server.lua

for peerIndex = 1, host:peer_count() do
    local peer = host:get_peer(peerIndex)
    if peer then
      peer:send("Hi")
    end
  end

It took time to dig some issues to find this. #19

If you have time to update some example on client and server for send, broadcast, channel and flag.

Attempt to index local 'host' (a nil value)

I am triyng to run server example but get error
