API coroutine.resume

Begins or resumes a coroutine. success [, ...] = coroutine.resume(co [, ...]) success, errMsg = coroutine.resume(co [, ...])

• co: - A suspended coroutine.
• ... : Variable arguments - Return values for when resuming, or the function header if it didn't begin yet.

• success: - when the coroutine runs without error.
• ... : Variable arguments - Arguments supplied to if the coroutine yielded, or return values if it reached the end.
• errMsg: - A description of the error, or why success was.

• There is an implicit, so execution can resume even when an error occurs inside the coroutine.
• If the coroutine had previously reached its conclusion, success will be false.

Yields every 1ms and resumes on the next frame until completion.
