===New (to UT2004) debugging console commands===



*Console command <code>Utrace</code> - simple on/off toggle. When on it floods the log, so be careful. When on can easy flood log with GB of output!

*Console command <code>UTrack ObjectName PropertyName</code> - It works only when UTrace is enabled. You can pass class name or object name as the first argument, and property name as the second value.

*:Changes will appear in UTrace log as on screens above.
*Console command <code>UProfile</code> - collects all uscript usage and when turned off dumps in format which almost json and can be parsed by js if needed.

*:It is good for finding slow functions or functions that are called a lot, to allow you to optimise code.
*Console command <code>DEBUGBREAK</code> - when called in code emits a break for the C++ debugger (not UDebugger). It's for engine developers where they have code & pdb files, and need stop in an exact place. They can modify code and emit that console command and the engine will stop at the desired place.

<code>UProfile</code> ends automatically when game exits.

<code>UTRACE</code> and <code>UPROFILE</code> commands can be passed as command line arguments for the game. That turns them on in an early stage to get info about engine startup.
