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 transformers the current ball type can be changed.
目录
Types
Wooden ball
The default type of ball when the player starts at Level 1–12. It has a mass of 1.9 tons, with a brownish-yellow wooden texture. It is made by gluing and splicing wooden strips with some green spots and scratches.
质量轻且灵活，是三种球类中手感最为均衡的。它可以推动各种机关，但需要一定的助跑；遇见大量机关时（如大量箱子）显得无能为力。此外，它可以被最少6个风扇叠加吹起；理论上可以跨过无数个箱式浮板（需要高技术水平）。
Stone ball
The default ball type on start of Level 13. 质量为10吨。外观总体上呈青绿色，表面有大量的坑。它的力量大，可以无需助跑推动各种机关；沙袋不容易阻挡它；但它的惯性巨大，不易操控。不过由此也可以被用在自制地图中通过“过山车”式设计。事实上，第9、13关就有了这种设计。它还可以使软木桥断裂。此外，它可以被最少32个风扇叠加吹起；理论上可以跨过3个箱式浮板（需要高技术水平）。
Paper ball
The paper ball weighs 0.2 ton. There does not exist any paper transformers in unmodified Level 1, and paper ball also cannot be used。其外观为数张报纸粘合而成的不规则白色球体，棱角分明；十分轻盈，可被风扇吹起，不会压开箱式浮板，但是不能推动大多数机关（升降机围墙可以被纸球用力助跑推开；推板在特定情况下能够被推开；箱子可以非常困难地推开；单摆可以被轻松推开）。此外，由于其表面不平整，因此无法以任何方式（包括借助定位杆对齐）与单轨对齐而安全通过。
Physical parameters
Below are parameters of three types of balls (bold denotes difference from prop balls):
| Type | Diameter of hitbox (meter) | Friction | Elasticity | Mass (ton) | Linear damping | Rotational damping | Force |
|---|---|---|---|---|---|---|---|
| Wood | 4.0 | 0.8 | 0.2 | 1.9 | 0.9 | 0.1 | 0.43 |
| Stone | 4.0 | 0.5 | 0.1 | 10.0 | 0.3 | 0.1 | 0.92 |
| Paper | Mean 4.0, maximum 5.0 | 0.5 | 0.4 | 0.2 | 1.5 | 0.1 | 0.065 |
Note: "Force" is the force on the ball when it is made to roll by the player pressing down the keyboard; as a result, it is meaningless to the prop balls.
For references, below are parameters of prop balls:
| Type | Diameter of hitbox (meter) | Friction | Elasticity | Mass (ton) | Linear damping | Rotational damping |
|---|---|---|---|---|---|---|
| Wood | 4.0 | 0.6 | 0.2 | 2.0 | 0.6 | 0.1 |
| Stone | 4.0 | 0.7 | 0.1 | 10.0 | 0.2 | 0.1 |
| Paper | Mean 4.0, maximum 5.0 | 0.5 | 0.4 | 0.2 | 1.5 | 0.1 |
Effects
- Balls can activate checkpoints.
- Only when a ball comes near the modules will they be loaded, otherwise they are "frozen".
- Stone ball can break down suspension bridges on contact, regardless of its mass (if changed by modifying Balls.nmo); however the prop stone ball will not do so.
Did you know
- 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.
- Though 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。
- APaper balls can be blown by ventilators while prop paper balls can't.
