Studying this new BroadcastHandler code I can see how all this is quite possible.
I cannot for the life of me see why Epic did things this way and why the hell EL Meurte went this route, but then he's so far up Epics butts.
Anyways let me explain the difference between the 2 BH's
The Original BroadcastHandler which came with DVD on release.
This BH was identical to the BH of UT2003 except for a few minor changes.
Everthing to do with the text messaging to players is handled by the BH and is the only way a Mutator can get to the messages.
In UT1 and UT99 a Mutator had direct access to the Broadcast GameInfo but this is where the "hackers" and cheaters got in so the loophole was closed in UT2003.
With the original BH, you could get to everything and by that I mean the routines where the original author typed the message, to the error checking routine, all the way down to where the message is distributed to all the other players and finally you also get to the point where it actually displays on the clients screen clientside.
To access the BH, you would save the current BH's Handle as 'OldHandle' and replace its Handle with whatever your current Mods Handle is, then once all the routines are executed in your 'Handle', your Mod would now pass the game onto the "OldHandle", in otherwords all the BH's are chained together in series.
In this way all Mutators could share all the info in the BH and just pass it on to the next Handler and so on and everyone was happy.
However, it did have one very major flaw which was excessively used by TTM2003 (the sole reason modders hated these authors so much) in that you could not pass it on to the next "Handle" or pass it on but in several functions, leave out some vital information which would "starve" other Mutators further up the chain.
Many people complained to Epic about this, including me, but I for one never ever expected they would fix the problem in such a drastic manner.
The "Fixed" BroadcastHandler introduced in the 2nd Patch for UT2004.
This BH (current) the Mutator author is very limited to which function he can get his hands on.
These functions are limited to the Error routines and the final routine which sends the message out to everyone.
So the 2 functions that Zound so desperately need, the ones where the original author of the message types his/her message is now no longer available and Zound has to find its way through the garbled mess where all the messages are sent out to all players.
The actual way in which Mutators hook into this new BH is excellent in that we now "Register" our BH with the games "Main" BH and it now inturn passes the game out to all the BH like in a Star format and it too works very well, PROVIDED someone does not come along and use the old style as it wont be seen anymore.
Anyways hopefully we conquer this beast soon
