Ballance is a 3D puzzle computer game. It was developed by Cyparade and published by Atari. The player controls a ball that he or she must move from one point to another without falling off the screen.
In the game, the player can change the ball's material with special changers throughout levels. It can be a wood, rock, or paper ball. The wooden ball is very stable and can be used for several puzzles in the game. It is the very first ball, used in the easy levels. The rock ball is extremely heavy, and can be accidentally rolled off an edge very easily, but this ball can easily push down boxes and bridges. Rolling a rock ball through a bridge made of planks will make the bridge collapse and cause loss of one life. The paper ball is very light. Its surface is not smooth, unlike the wood and rock ball, and can be a bit rough at first. A paper ball can be blown into the air by fans and can roll up steep hills easily.
I have enjoy this for many years, but only can control it by keyboard.
Since I've seen the SunSPOT. An magic idea has come out: can we play this game by our SPOT? That must be a cool experience and conception for students.
I have used one Sun SPOT and one basestation for this demo, the Sun SPOT collects data "dy" and "dx" from the 3-axis accelerometer and sends to basestation by the wireless. And the basestation which is connected to PC receives data and control mouse or keyboard according to data.
In the Ballance game, we define up as "w", down as "s", left as "a" and right as "d". When the Sun SPOT collects "dx" is smaller than -0.3, the basestation types "a", "dx" is larger than 0.3, the basestation types "d". The "dy" controls up and down as same.
I think we can play more and more games by Sun SPOT like the Nintendo Wii, it's cool. You can see this demo in youtube! Enjoy Sun SPOT!
