Event System

វាជា system events ដែលត្រូវ dispatched ក្នុងការ notify កម្មវិធីនៃ external events ដូចជានៅពេលដែល device ត្រូវការ suspend​ or exit កម្មវិធី។ Events ទាំងអស់នេះគ្រាន់តែផ្ងើរទៅកាន់ global runtime object

"applicationStart" occurs when the application is launched and all code in main.lua is executed.

"applicationExit" occurs when the user or OS task manager quits the application.

"applicationSuspend" occurs when the device needs to suspend the application such as during a phone call or if the device goes to sleep (from inactivity or user action). In the simulator, this corresponds to selecting "Suspend" from the Hardware menu. During suspension, no events (not even enterFrame events) are sent to the application while suspended, so if you have code that depends on time, you should account for the time lost to an application being suspended.

"applicationResume" occurs when the application resumes after a suspend. On the device, this occurs if the application was suspended because of a phone call or sleep. In the simulator, this corresponds to selecting "Resume" from the Hardware menu.

"applicationOpen" occurs when the application is asked to open a URL resource (iOS-only)
