If(...) will not be executed.

[Tuetenpenner]

This is my first Addon and I need some Help. The if() which includes the function FollowUnit() will not be executed. Also my OnWhisper() function seems to be executed twice.

local f = CreateFrame("Frame");
f:RegisterEvent("CHAT_MSG_WHISPER");
f:RegisterEvent("CHAT_MSG_BN_WHISPER");
 
function Follower_OnLoad()
    DEFAULT_CHAT_FRAME:AddMessage("Follower Loaded!", 1.0, 0.0, 0.0, 3.0);
end
 
f:SetScript("OnEvent", function(self, event, ...)
    if(event == "CHAT_MSG_WHISPER" or "CHAT_MSG_BN_WHISPER") then
        local arg1, arg2 = ...
 
            if(event == "CHAT_MSG_BN_WHISPER") then -- Yet no function.
 
            end
 
            OnWhisper(arg1, arg2)
    end
end)
 
function OnWhisper(arg1, arg2) -- The whole function seems to be executed twice.
    if (arg1 == "f_follow") then
        print("Following " .. arg2)
 
            if (CheckInteractDistance(arg2, 4)) then -- This part will not be executed. Instead it goes to the else part.
                FollowUnit(arg2)
            else
                SendChatMessage("I'm too far away to follow you!", "WHISPER", nil, arg2)
            end
    end
end

A player's name is not a valid unitID unless they're in your group.

In other words.. you can run FollowUnit on an arbitrary player name, but you can't run CheckInteractDistance on someone's name who isn't in your group.

Ok but it doesn't work with characters in a group too. I tried the function with a macro and that did work.

Strip the realm out of their name, eg. arg2:match('^[^-]+')
