/melody
I was looking at a packet collect from Live using /melody this morning, and the key reasons it doesn't work in EQEmu are:
1. The client wants an OP_MemoriseSpell sent to it before OP_Action/OP_Damage. This is what triggers it to 'cast' the next song.
2. The client sends a zero length OP_ManaChange packet between each song, which the server currently responds to with an OP_Interrupt spell.
The following 'hack' enables /melody

I say 'hack' because I'm not in my comfort zone in the spell code and I suspect my 'StopSong' may not be the correct way to handle things. I'm working on other stuff at the moment, so if someone else wants to pick this up and refine it, feel free :) |
