Arguments that needs to be passed down
Rest ...args: any[]Creates an event emitter instance to listen for the actions
Call the function to remove the event
Rest ...args: any[]Adds the listener function to the beginning of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.
Rest ...args: any[]Adds a one-time listener function for the event named eventName to the beginning of the listeners array. The next time eventName is triggered, this listener is removed, and then invoked.
Rest ...args: any[]This event is called when a touch screen motion event starts.
