hey i have more a question than an issue:

is there a way to edit the commands of commandsblock (should be a tileEntity)
in the source/TileEntity i only found blocks like chests sign etc.
if yiu are able to do that how does it work?
maybe with chunk.SetBlockData(x, y, z, ???);
an answer would really help me on my project!

greetings M4GNV5
