or just update your compat.lua in libs

what about broadcastMessage = doBroadcastMessage ?

 

[Infernum]

what about broadcastMessage = doBroadcastMessage ?

That's completely irrelevant, which was my point.
He's not calling broadcastMessage, he's calling Game.broadcastMessage, where the broadcastMessage field of the Game table is missing, which is why I provided the link to the function.

@Infernum hey bro thanks for your reply

I'm using this distro

GitHub - mattyx14/otxserver: OTX Server from:

OTX Server from:. Contribute to mattyx14/otxserver development by creating an account on GitHub.

github.com

Should I just add:

forgottenserver/data/lib/core/game.lua at master · otland/forgottenserver

A free and open-source MMORPG server emulator written in C++ - otland/forgottenserver

github.com

to the directories /data/lib/core/game.lua#L1-L9 from previous reference or should I update something else in the project for a whole benefit?

I'm pretty new into tibia-servers coding but I get a lot of references right now because I'm into coding these quarantine days so please advice me if I should update something there for a whole benefit.

Btw I wanted to know if possible, how can I add 8.6 outfits + addons to this TFS? It's using a custom client but IDK where;s the source of the client lol

Just add the function to the lib file.

Just add the function to the lib file.

Hey @Infernum sorry for the delay on replying last night we had terrible weather over my IP

EDIT:

Now this is happening, event triggers but it keeps saying it will start in 3 minutes it loops on that

[17/4/2020 15:53:6] Description:
[17/4/2020 15:53:6] (LuaInterface::luaAddEvent) Callback parameter should be a function

Btw the source code I showed you up is like the fork of the server I'm using but it's not 100% that server, it's a fixed 7.6 idk but the whole lib directory is VERY different



Edit: I noticed the error was on the onThink so I searched for that in the IDE and I found that another function that well it's not bugged, uses this function:
doBroadcastMessage
instead of:
Game.broadcastMessage

Can anyone guess by experience what TFS I'm using lol I'm blind there's no reference in the code I downloaded


Added the whole script inside the globalevent.lua, it runs, but it throws this error after the 3 mins.
