Packet and Function Confusion

[SoundsFine]

I was decompiling a mod and found this, 

this.mc.func_147114_u().func_147298_b().func_179290_a((Packet)new C07PacketPlayerDigging(C07PacketPlayerDigging.Action.START_DESTROY_BLOCK, new BlockPos(currPoint.func_177958_n(), currPoint.func_177956_o(), currPoint.func_177952_p()), EnumFacing.UP));

I'm wondering where I can find the code for the func_xxxxx and C07PacketPlayerDigging. A while ago I was working on an MCP client and I found where the func_xxxxx's were, but now I can't find them. Thanks for any help!

dont do that

If you're implying it was a hacked client it wasn't. It was (meant) to be a PVP client like Lunar or BLC, but it never got close to completion XD

Custom clients are not supported on this forum, and are not encouraged in general (yes, clients such as BLC and Lunar are looked down upon in the modding community due to violation of Mojang's wishes and account security threats).

If you want to modify the game, use a mod instead (although keep in mind that "anti-cheat" clients and fundamentally flawed and will not work).
