最近学了下pygame, 感觉非常有意思, 于是用自己的理解纯手工敲了几个游戏, 下面记录一下我做飞行棋的思路过程:
运行结果
玩家轮流投骰子然后移动飞机, 全程只用鼠标操作, 右上方会提示当前的轮次及操作
基础设置
1) 首先是导包和初始化一些变量, 定义SIZE=40表示长方形的宽, 里面的长方形地区长宽比为2:1, 三角形直角边等于长方形的长, 出发地的边长等于长方形宽度的4倍
2) 游戏里设置了100帧, 设置几百都没问题(只要电脑带的动)
3) 没有导入pygame包的话就在终端输入pip install pygame即可自动下载.
import pygame, random
from pygame.locals import
# 基础设置
pygame.init()
WIDTH = 680 # 正方形棋盘边长
SIZE = 40 # 小格子正方形大小
sur = pygame.display.set_mode((WIDTH+100, WIDTH))
pygame.display.set_caption('FlightChess') # 标题
FPS = 100 # 帧率
fpsClock = pygame.time.Clock()
颜色变量
一些颜色RGB值变量的初始化, RGB值就是用红绿蓝三个色度来表示最终的颜色, 每个色度为0-255, 例如(0, 0, 0)表示黑色
# 颜色变量
# 颜色变量
WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 128, 0)
BLACK = (0, 0, 0)
YELLOW = (233, 233, 0)
BLUE = (62, 105, 22
画棋盘
首先先看几个函数的定义
1) 在圆心为(x, y)半径为R的圆中画一个颜色为color的飞机
def draw_plane(x, y, color):
# 机身
pygame.draw.line(sur, color, (x+9, y), (x-8, y), 3)
pygame.draw.line(sur, color, (x+9, y), (x+12, y), 2)
# 尾部
pygame.draw.line(sur, color, (x-8, y), (x-11, y-4), 3)
pygame.draw.line(sur, color, (x-8, y), (x-11, y+4), 3)
# 机翼
pygame.draw.line(sur, color, (x+3, y), (x-3, y-6), 3)
pygame.draw.line(sur, color, (x-3, y-6), (x-6, y-9), 2)
pygame.draw.line(sur, color, (x+3, y), (x-3, y+6), 3)
pygame.draw.line(sur, color, (x-3, y+6), (x-6, y+9), 2)
2) 在圆心为(x, y)的地方画一个白色圆, 半径为R
def draw_circle(x, y):
pygame.draw.circle(sur, WHITE, (x, y), R, R)
pygame.draw.circle(sur, BLACK, (x, y), R, 1)
3) 在左上角(x, y)坐标处开始画一个三角形, 三角形有4中形态
type==0 时直角在左上角, type==1时直角在右上角, type==2时直角在右下角, type==3时直角在左下角
zdef draw_triangle(x, y, color, type):
if not type:
pygame.draw.polygon(sur, color, ((x, y), (x+SIZE2, y), (x, y+SIZE2)))
draw_circle(x+L, y+L)
pygame.draw.polygon(sur, BLACK, ((x, y), (x+SIZE2, y), (x, y+SIZE2)), 2)
elif type == 1:
pygame.draw.polygon(sur, color, ((x, y), (x + SIZE 2, y), (x+SIZE2, y + SIZE 2)))
draw_circle(x+R+SIZE, y+L)
pygame.draw.polygon(sur, BLACK, ((x, y), (x + SIZE 2, y), (x+SIZE2, y + SIZE 2)), 2)
elif type == 2:
pygame.draw.polygon(sur, color, ((x, y + SIZE 2), (x + SIZE 2, y), (x + SIZE 2, y + SIZE 2)))
draw_circle(x + R+SIZE, SIZE+y + R)
pygame.draw.polygon(sur, BLACK, ((x, y+SIZE2), (x + SIZE 2, y), (x+SIZE2, y + SIZE 2)), 2)
else:
pygame.draw.polygon(sur, color, ((x, y), (x + SIZE 2, y + SIZE 2), (x, y + SIZE 2)))
draw_circle(x + L, y + R+SIZE)
pygame.draw.polygon(sur, BLACK, ((x, y), (x + SIZE 2, y+SIZE2), (x, y + SIZE 2)), 2)
4) 在(x, y)画一格颜色为color的长方形
type=0为横着, 1为竖着
def draw_block(x, y, color, type):
if type: # 竖
sur.fill(color, (x, y, SIZE, SIZE 2))
pygame.draw.polygon(sur, BLACK, ((x, y), (x+SIZE, y), (x+SIZE, y+SIZE2), (x, y+SIZE2)), 2)
draw_circle(x+20, y+40)
else: # 横
sur.fill(color, (x, y, SIZE 2, SIZE))
pygame.draw.polygon(sur, BLACK, ((x, y), (x+SIZE2, y), (x+SIZE2, y+SIZE), (x, y+SIZE)), 2)
draw_circle(x+40, y+20)
5) 画棋盘
下面是画棋盘的一部分代码
draw_triangle(0, 160, GREEN, 2)
draw_block(80, 160, RED, 1)
draw_block(120, 160, YELLOW, 1)
draw_triangle(160, 160, BLUE, 3)
draw_triangle(160, 160, GREEN, 1)
draw_block(160, 120, RED, 0)
draw_block(160, 80, YELLOW, 0)
draw_triangle(160, 0, BLUE, 2)
draw_block(240, 0, GREEN, 1)
draw_block(280, 0, RED, 1)
draw_path((240, 160+L), (440, 183), GREEN)
pygame.draw.circle(sur, BLACK, (L, 160+L), R, 2)
draw_end_place(YELLOW)
draw_start_place(0, 0, RED)
画出了差不多这一部分(不完全准确), 剩下的自行根据坐标来定义即可
变量思路
做完了界面, 就该考虑逻辑怎么实现了
首先我把棋盘分成了三个部分来放飞机, 出发地, 周围一圈, 终点路径
出发地
initpos = 【【0 for in range(5)】 for in range(4)】
周围一圈
grid = 【0 for in range(52)】
终点路径
endpos = {RED: 【False for in range(6)】,
YELLOW: 【False for in range(6)】,
BLUE: 【False for in range(6)】,
GREEN: 【False for _ in range(6)】}
飞机类, 表示一架飞机, 包含目前的所有信息
class Chess:
step = STEP # 还差多少步到终点
start = 0 # 飞机目前的状态, 0未出发, 1在棋盘上, 2在终点路径
color = (0, 0, 0) # 颜色
x, y = 0, 0 # 界面的笛卡尔坐标
idx = 0 # 棋盘对应部分的下标
def init(self, color, x, y, start, idx):
self.color = color # 飞机颜色
self.x, self.y = x, y
接下来在每次循环里面都画出飞机即可, 遍历每个部分是否有飞机
while True:
draw_grid()
draw_point()
# 画出出生地的飞机
for i in range(len(init_pos)): # 4
for j in range(len(init_pos【0】)): # 5
if init_pos【i】【j】:
draw_plane(init_pos【i】【j】.x, init_pos【i】【j】.y, init_pos【i】【j】.color)
# 画出棋盘中的飞机
for c in grid:
if c: # 此格有飞机, 画出飞机
draw_plane(c.x, c.y, c.color)
# 画终点路径的飞机
for i in end_pos:
for c in end_pos【i】:
if c:
draw_plane(c.x, c.y, c.color)
关于投骰子, 用random随机数来获取点数, 并将其显示在棋盘右边的位置, 投骰子的时间为0.5s, 实现的方法:
t = 0
while True:
...
if not moving and geting_point: # 投色子
t += 1/FPS
point = get_point()
if t >= 0.5:
t = 0
geting_point = False
move = True
核心逻辑
大致思路:
1. 点击后判断点击的位置是否在棋盘内
1) 在棋盘内
找到点击位置的飞机, 然后根据一系列规则和更新来维护棋盘
2) 在棋盘外
点击到了骰子, 若条件满足则开始投骰子
3) 无效点击
指点击了没反应, 在棋盘内没点击到棋子或者点击到了不是此轮此的棋子或者无法移动的棋子
在棋盘外点击了除骰子以外的地方或者条件不符合投骰子
2. 中途包含了非常多的细节, 这里就不一一叙述, 感兴趣请看全部代码.
全部代码
规则一览:
1) 点数 >= 5 时飞机才能出发, 若场上没有可移动的飞机, 自动跳过回合
2) 对于可移动的飞机, 点数丢到多少就可移动多少格
3) 飞机落点在同色块时会自动跳到下一个同色块(4格), 若是有虚线的同色块, 则会沿着虚线跨越到对面(12格)
4) 相同颜色飞机无法落在同一格, 此时会无法点击想要移动的飞机
5) 若落点处有不同颜色的飞机, 会将其打回出发点
