Module gamejs/event

Mouse and keyboard events.

All events have a type identifier. This event type is in between the values of NOEVENT and NUMEVENTS. Each event has a constant in gamejs.event.* All user defined events can have the value of USEREVENT or higher. Make sure your custom event ids* follow this system.

Example 

gamejs.onEvent(function(event) {
       if (event.type === gamejs.event.MOUSE_UP) {
         gamejs.log(event.pos, event.button);
       } else if (event.type === gamejs.event.KEY_UP) {
         gamejs.log(event.key);
       }
    });
