This page is about the ball that can be directly controlled by the player by pressing down buttons on the keyboard, not the Prop ball, which is a module and used as a type of props.
The appearance of three types of ball (from left: paper ball, wood ball, and stone ball).

Ball, or called the player ball, is the core of Ballance and the only element that can be controlled py the player directly. The mean diameter of every type of ball is 4 meters: the shapes of wood ball and stone ball are perfectly round, while the paper ball is irregular, with its maximum width being 5 meters.

目录

Types

Wood 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. 是由带有些许青斑和划痕的木条粘合拼接而成。

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

13关出生时默认的球。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

质量为0.2吨。第一关中不存在纸球变球器。外观上是由数张报纸粘合而成的一个不规则白色球体,棱角分明。最大特点是十分轻盈,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,因此不能借助定位杆对齐通过单轨。

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

  • 球可以触发存档点
  • 仅有球到达机关附近时,机关才会加载。其余时间机关是静止的。
  • 石球(无论修改其质量为何值)可以在接触时使软木桥断裂。但是需要注意的是,道具石球并不会产生此效果。

Did you know

  • 木球和石球的形状是直径为4米的正球形,且被脚本写死;纸球的形状则是不规则的,通过修改Balls.nmo甚至可以更改其形状。
  • 虽然纸球的弹力是石球的4倍,木球的弹力是石球的2倍,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。
