Add Parameters (0 ) No parameters. Returns (1 )
History 1 Requires PluginOrOpenCloud security; not callable from game scripts.
Registers instance as a coverage root so the engine records per-line and
per-function execution coverage for instance and every script descended
from it. Retrieve the recorded data with
ScriptContext:GetCoverageStats() .
History 1 Fires when an unhandled error occurs while running a script, reporting the
error to any listening code. The engine raises this event from its
error-reporting path when a thread terminates with an error, passing the
error message, a formatted stackTrace string, and the script that
was running.
This event does not fire for errors raised by the watchdog when a script
exceeds its execution-time limit (see ScriptContext:SetTimeout() ).

Add Parameters (0 ) No parameters. Returns (1 )
Requires PluginOrOpenCloud security; not callable from experience
scripts. Returns an array of coverage results, one entry per tracked
script. Each entry is a table with a Script field (the script
Instance ) and a GetHits() function. Calling GetHits() returns
two arrays: per-line hit counts, where -1 marks a line that was never
executed or was excluded, and per-function records containing each
function's Name, Line, and Hits.
Like ScriptContext:EnableCoverage() , this method raises an error
if coverage collection is not enabled.

History 1

History 11 Tags: [Hidden]
Sets the watchdog time limit that the engine applies to running scripts.
The value becomes the per-resumption execution budget: if a thread runs
for longer than seconds since it was last resumed without yielding, the
watchdog aborts it with the runtime error
Script timeout: exhausted allowed execution time.
The timeout defaults to 0, which disables the watchdog so that scripts
may run without any time limit. Call this method with a positive value to
enable enforcement, or pass 0 to turn it back off.
