Why the event processing does not work correctly in my code?

Hi everybody.

I try to write an addon. Need to handle some events, for this I created a frame. In the Internet there are many examples of code similar to this one:

local frame = CreateFrame("Frame");

frame:RegisterEvent("PLAYER_ENTERING_WORLD");
frame:RegisterEvent("PLAYER_REGEN_DISABLED");
frame:RegisterEvent("PLAYER_REGEN_ENABLED");

frame:SetScript("OnEvent", function(self, event, ...)
    DEFAULT_CHAT_FRAME:AddMessage("OnEvent");   --[[Message is displayed--]]

    if event == "PLAYER_ENTERING_WORLD" then
        DEFAULT_CHAT_FRAME:AddMessage("entering the world");   --[[Condition does not triggers --]]
    elseif event == "PLAYER_REGEN_DISABLED" then
        DEFAULT_CHAT_FRAME:AddMessage("entering combat");   --[[Condition does not triggers--]]
    elseif event == "PLAYER_REGEN_ENABLED" then
        DEFAULT_CHAT_FRAME:AddMessage("leaving combat");   --[[Condition does not triggers--]]
    end;
end);

The frame is created, subscribed to the events, the handler is triggered by these events, but the conditions in the handler do not work. What am I doing wrong?

However, everything works if I create a frame through XML, and there I hang a handler function on it. I can stop at this, but curiosity does not give rest - why the above code does not work?

Thanks for any help.

In vanilla the script functions take no parameters. OnEvent use the global `event` variable, all other scripts use globals `arg1`, `arg2`, `arg3`, etc. Removing the paramenters of the function should be enough to have something working.

Also, global `this` variable is set instead of self.
