'''Ball''', or called the '''player ball''', is the core of [[Ballance]] and the only element that can be controlled by the player directly. The mean diameter of every type of ball is 4 meters: while the shapes of wood ball and stone ball are perfectly round, the paper ball is irregular, with its maximum width being 5 meters. By using [[transformer]]s the current ball type can be changed.

* Shapes of the wood ball and the stone ball are perfect balls with the diameters of 4 meters, which are fixed in scripts, which means that only the appearances, not the hitboxes of wood/stone balls can be changed by modifying Balls.nmo; the shape of paper ball is irregular and its hitbox can even be modified in Balls.nmo. 而在Balls.nmo中修改其余两种球的形状，只会改变它们的外观，而它们正球体的碰撞箱不会变。* 虽然默认纸球的弹力是石球的4倍，木球的弹力是石球的2倍，修改BallsThough the paper ball has a elasticity 4 times of the stone ball, 2 times of the wood ball, 修改Balls.nmo时将三者等比调高，制作出[[弹力球]]时却会导致石球表观弹力高于木球，木球表观弹力高于纸球。推测这可能是三者空气阻力不同所致。
