Description

Internal-only (InternalTest security); not available to ordinary experience scripts. CustomLog writes text to a file in the engine's logs directory: CustomLog:Open() creates a file named after the instance's Instance.Name (with a .log extension), CustomLog:WriteAppend() appends text, and CustomLog:Close() closes the file handle. The instance cannot be parented to or contain other instances.

Close

Parameters (0)
No parameters.
Returns (1)
null

Closes the file handle previously opened by CustomLog:Open(). Closing an already-closed log has no effect.

History 1

GetLogPath

Parameters (0)
No parameters.
Returns (1)
string

Returns the full filesystem path of the log file targeted by CustomLog:Open(). The path is set when CustomLog:Open() is called and is derived from the instance's Instance.Name; it is empty before the log has been opened.

History 1

Open

Parameters (0)
No parameters.
Returns (1)
null

Opens a file named after the instance's Instance.Name (with a .log extension) in the engine's logs directory, truncating any existing contents so that writing starts from an empty file.

This method throws a runtime error if the log is already open, if Instance.Name is empty, if the name resolves to a path outside the logs directory, or if the file otherwise fails to open.

History 1

WriteAppend

Parameters (1)
appendstring
Returns (1)
null

Writes append to the end of the open log file. The text is written verbatim, without adding a trailing newline.

This method throws a runtime error if the log is not open (call CustomLog:Open() first) or if the write fails.
