Now all you need to do is pass that bitmap to the new class in the draw method with:. Now click run and you should see your graphic appear on your screen! This is BeeBoo.

I used to draw him in my school textbooks. What if we wanted to make this little guy move? Simple: we just create x and y variables for his positions and then change these values in an update method. So add the references to your CharacterSprite and then then draw your bitmap at x, y. Remember, y coordinates are measured from the top so 0 is the top of the screen. Of course we need to call the update method in CharacterSprite from the update method in GameView.

This will make our graphic bounce around the screen off the edges, like those old Windows screensavers. You know, the strangely hypnotic ones. There is plenty more to delve into here, from handling player input, to scaling images, to managing having lots of characters all moving around the screen at once. Right now, the character is bouncing but if you look very closely there is slight stuttering.

The speed also varies a lot on the emulator compared to a physical device. Now imagine what happens when you have tons going on on the screen at once!

There are a few solutions to this problem. This will have the value of For that, I also want a private double called averageFPS.

On the emulator though you might get a different result. Try changing that 60 to 30 and see what happens. The game slows down and it should now read 30 in your logcat. There are some other things we can do to optimize performance too.

Try to refrain from ever creating new instances of Paint or bitmaps inside the loop and do all initializing outside before the game begins. I hope this guide has helped somewhat and wish you the best of luck in your upcoming coding ventures! Android Development.

The identify of food is random, but identity of cell is meaningful , so I would rather make a class Cell than food. Cells are also important to kep track of position of the snake! It is the set of valid points for the game to function on, qualitatively a matrix of cells. While the cells revert to the questions, being the collection and home of cells, the board needs to ensure the cells get satisfiable answers.

Whether it contains food or not? We need to assign food to some random cell as well. This is attributed to the board, as the cell doesn't choose whether it shall contain food, the board is acquainted with the cells it contains and hence should empowered to assign a cell to contain food. Whether it is a part of the snake or not? This is answered by the Snake class we described above. Improve Article.
