Relay server chat to discord.

sv_discordrelay.lua

--[[
Gmod to Discord Chat Relay:
Have your chat display in discord!

You need a Webhook URL to make this work.

Step 1: Go into discord, and hover your mouse over the desired channel you'd like messages to be sent to.
Step 2: Click on Edit Channel, and click on Webhooks.
Step 3: Click on "Create Webohook"
Step 4: Fill in a default username, and give it an avatar of your choosing. Then click save. Edit it again before going onto step 5
Step 5: Copy and paste the webhook URL down below.

You need a SteamWebAPIKey for avatars to be fetched.

Step 1: Goto http://steamcommunity.com/dev/apikey
Step 2: Fill in a domain name, I recommend the IP address of your server.
Step 3: Copy and paste the key down below.

hook.Add("PlayerSay","Discord_Webhook_Chat", sendChat)

is there anything i need to replace besides the api and the webhook url?

The actual relay worked instantly, but avatars don't work, despite having the correct api key inputted.

how does one install this?? (yes I'm a dumb ass lmao)

use webhooks guys

Not actual.

how do i install it?

where do i paste the code please help fast

I updated the gist to show where it goes, though you should probably use a better script with two way relay, this only sends to discord, not the other way around.
