for c in cushions: create_cushion(c)

这段代码是用来创建球桌周围的边缘垫子的,其中:
- `cushions` 是一个列表,其中存储了多个多边形的顶点坐标列表,用来描述球桌的边缘垫子的形状。
- `for c in cushions:` 是一个循环语句,用来遍历 `cushions` 列表中的每一个元素,即每一个多边形的顶点坐标列表。
- `create_cushion(c)` 调用自定义函数 `create_cushion()`,并将当前多边形的顶点坐标列表 `c` 作为参数传入,用来创建一个静态的多边形刚体,表示球桌的一段垫子。函数内部的实现和作用已经在上一段代码中详细解释过了。
总体来说,这段代码的作用是遍历球桌周围的边缘垫子的顶点坐标列表,并将每一个多边形的顶点坐标列表传入 `create_cushion()` 函数中,用来创建一个静态的多边形刚体,表示球桌的一段垫子。最终,所有的垫子都将参与到物理模拟中,成为球的弹射、滚动、碰撞等行为的限制和影响因素。

解释下面这段代码balls = [] rows = 5 for col in range(5): for row in range(rows): pos = (250 + (col * (dia + 1)), 267 + (row * (dia + 1)) + (col * dia / 2)) new_ball = create_ball(dia / 2, pos) balls.append(new_ball) rows -= 1 pos = (888, SCREEN_HEIGHT / 2) cue_ball = create_ball(dia / 2, pos) balls.append(cue_ball) pockets = [ (55, 63), (592, 48), (1134, 64), (55, 616), (592, 629), (1134, 616) ] cushions = [ [(88, 56), (109, 77), (555, 77), (564, 56)], [(621, 56), (630, 77), (1081, 77), (1102, 56)], [(89, 621), (110, 600), (556, 600), (564, 621)], [(622, 621), (630, 600), (1081, 600), (1102, 621)], [(56, 96), (77, 117), (77, 560), (56, 581)], [(1143, 96), (1122, 117), (1122, 560), (1143, 581)] ] def create_cushion(poly_dims): body = pymunk.Body(body_type=pymunk.Body.STATIC) body.position = ((0, 0)) shape = pymunk.Poly(body, poly_dims) shape.elasticity = 0.8
这段代码主要是针对一个台球游戏的物理模拟部分,其中包含了以下几个部分:
1. 创建球的列表:首先创建了一个空列表 balls,用于存放所有的球,包括球台上的球和球袋中的球。
2. 创建球:通过嵌套的循环,创建了球台上的所有球,其中 rows 的初始值为 5,col 和 row 分别表示球的列数和行数,pos 表示球的位置,new_ball 表示新创建的球,dia 是球的直径,create_ball 是一个函数,用于创建球,并且将新创建的球添加到 balls 中。
3. 创建球袋和弹垫:pockets 和 cushions 分别表示球袋和弹垫的位置,其中每个位置都是一个二元组,表示位置的 x 和 y 坐标。
4. 创建弹垫的物理对象:通过 create_cushion 函数,创建了弹垫的物理对象,其中 poly_dims 是一个列表,表示弹垫的四个角的坐标。
5. 设置弹性系数:通过 shape.elasticity = 0.8,设置了弹垫的弹性系数为 0.8。
这段代码主要是为了实现一个台球游戏的物理模拟部分,其中包含了球的创建和位置设置,以及球袋和弹垫的位置和物理模拟等相关内容。

Manufacturer Provided Description
The Leopard 40's speed on the water and easy handling are its top features, earning it 'Boat of the Year 2016' from Cruising World magazine. Guests will enjoy the large cockpit with outside dining area, protected by a functional hard-top bimini, fitted as standard. The galley-up design incorporates a spacious saloon and aft facing galley with a cocktail bar and serving window overlooking the cockpit. Accommodations include 3 or 4 double cabins, each with an en-suite head. The cockpit is a perfect place to relax and entertain guests, with comfortable seating and a table that seats 8. Forward and aft there are sunbathing lounges. All blocks and winches are electric, except for the mainsail halyard winch, which is conveniently located on the coachroof. The sail plan includes a full-batten mainsail, with stack-pack and lazy-jacks, and a roller-furling genoa. The Leopard 40 is also equipped with a generator and air conditioning.
