15. CGGM Lab, CSIE.NCTUKeng Shih-Ling 15 System::Kernel:: Task Jet Task Management System –Tasks provide Jet 's main frame-level update mechanism. Each task is called once-per- frame and may be suspended or resumed individually. –The Task Manager is responsible for initializing, updating, and uninitializing tasks. Tasks are added to the Task Manager and stored in a prioritized list in order from highest priority at the top of the list to lowest at the bottom.
