File structure

Function trace

When using Template:Cmd, a txt file titled debug-trace-yyyy-MM-dd_HH.mm.ss.txt is created in .minecraft/debug.

In this file,

  • [C] <command> means the <command> is executed.
  • [M] <message> means a message is returned.
  • [E] <message> means a failure message is returned.
  • [R = <num>] <command> means the <command> returns a brigadier return value.
  • [C] <command> -> <num> means the <command> is executed and returns a brigadier return value.
  • [F] <function> size=<num> means a function is called.

For most commands, the brigadier return value is equal to the result value that can be stored with /execute store result.

But for /execute ... with one or more of the following subcommands, each branch returns its success value as its brigadier return value:

  • ... if ... (not at the end)
  • ... unless ... (not at the end)
  • ... as <targets> ...
  • ... at <targets> ...
  • ... positioned as <targets> ...
  • ... rotated as <targets> ...
  • ... facing entity <targets> <anchor> ...

Some commands like /return and /function have no brigadier return value.
