Flash: preloader logic example

 / Published in: ActionScript 3
 

A method pulled from a Preloader class (vars _lastUpdate and _isComplete, _dotsExploded not included).

_lastUpdate = is the amount last sent to the preloader _isComplete = whether the preloader is finished _dotsExploded = an array of 10 falses (1/clip), as preloader advances each is set to true

This can be adapted for any preloader with 10 movieclips that need to do something every 10% loaded.

  1. /**
  2. * Updates the preload amount
  3. *	@parmam  percentLoaded		0-100 amount of load completed
  4. */
  5. public function update(percentLoaded:int = 0) : void 
  6. {
  7. 	if (percentLoaded <= _lastUpdate || _isComplete) return;
  8. 	_lastUpdate = percentLoaded;
  9.  
  10. 	var currentActiveSeed:int = Math.round(percentLoaded) / 10;
  11. 	for (var i:int = 0; i < currentActiveSeed; i++) {
  12. 		var seed:MovieClip = getChildByName("dot" + String(i + 1)) as MovieClip;
  13. 		if (!_dotsExploded[i]) {
  14. 			_dotsExploded[i] = true;
  15. 			seed.gotoAndPlay(2);
  16. 		}
  17. 	}
  18.  
  19. 	if (percentLoaded == 100) {
  20. 		_isComplete = true;
  21. 		dispatchEvent( new PreloaderEvent( PreloaderEvent.COMPLETE, true, false));
  22. 	}
  23. 	//trace("Loaded " + percentLoaded);
  24. }
