Developing the Game

Developing a cool “Casual Game” - SNAKE - in 10 minutes:

3 movieclips:• Snake’s head• Snake’s body piece• Apple

Then just call snakeAlive()Function on onEnterFrame.

Function snakeAlive() {

if (MyMng.isInPause) { return; }

If (KeyMng.isRight) { snake.goRight(); } else if (KeyMng.isLeft) { snake.goLeft(); } …

If (snake.isOnApple) { MyMng.scoring(1); snake.addBody(); }

}

Your Template should manages‘saves’ and ‘records’ for you.

Use MyMng.scoring(x), andit will be automatically saved.

Testing

How your game really runs on mobile

Devices do not react the same

That’s why it is important to test on all targeted devices

Optimizing

Significant optimizations from Mobitween’s experience:

Do not use too much vectors, prefer bitmaps when possible

Use the right bitmap format JPEG vs. PNG

Optimize shapes and outlines

Avoid animating lot of movie clips at the same time

Avoid complex uses of Math and loops

Avoid many code in the same frame
