Effect display

Essential materials

Main code

Import module

import pygame
import os.path
import csv
import setting as set
import live
import game_event
import gameui as gi
import startupui as si

Program main function

def run_game():
    #初始化pygame库
    pygame.init()
    #创建时钟对象(控制帧率)
    clock=pygame.time.Clock()
    #实例化设置类,用于导入游戏设置
    setting=set.Setting()
    #设置游戏窗口
    screen=pygame.display.set_mode((setting.screen_width,setting.screen_height))
    pygame.display.set_caption(setting.screen_caption)

Set different groups to handle various items respectively Relationship

#玩家组
group_player=pygame.sprite.Group()
#玩家的攻击组
group_attack=pygame.sprite.Group()
#敌人组
group_enemy=pygame.sprite.Group()
#敌人的攻击组
group_enemy_attack=pygame.sprite.Group()

Instantiated ui object

    #showinfo用于在游戏内显示人物血条等信息
    showinfo=gi.Info(setting,screen)
    #人物选择按钮
    yi_button=si.MonkeyKingButton(screen,setting)
    monkey_button=si.YiButton(screen,setting)
    fox_button=si.FoxButton(screen,setting)
    bin_button=si.BinButton(screen,setting)

Button of the game start interface

    pve_button=si.PVEButton(screen,setting)
    pvp_button=si.PVPButton(screen,setting)
    endless_button=si.EndlessButton(screen,setting)
    control_button=si.ControlButton(screen,setting)
    memory_button=si.RecordButton(screen,setting)
    cooling_button=si.CoolingButton(screen,setting)

Game background

    select_button=si.SelectButton(screen,setting)
    win_button=si.WinButton(screen,setting)
    dead_button=si.DeadButton(screen,setting)

The character mark currently selected by the player

    player_button_1=si.PlayerButton1(screen,setting)
    player_button_2=si.PlayerButton2(screen,setting)
    #空白按钮
    none_button=si.NoneButton(screen,setting)
    #空白图像
    none_info=gi.ExInfo(screen,none_button,setting.introduce_none)

Introducing the image of button function

    pve_info=gi.ExInfo(screen,pve_button,setting.introduce_pve)
    pvp_info=gi.ExInfo(screen,pvp_button,setting.introduce_pvp)
    endless_info=gi.ExInfo(screen,endless_button,setting.introduce_endless)
    control_info=gi.ExInfo(screen,control_button,setting.introduce_control)
    record_info=gi.ExInfo(screen,memory_button,setting.introduce_record)
    cooling_info=gi.ExInfo(screen,cooling_button,setting.introduce_cooling)

Button group (when drawing, the previous button will be covered by the following button)

    buttons=[select_button,yi_button,monkey_button,fox_button,bin_button,
             pve_button,pvp_button,endless_button,
             cooling_button,control_button,memory_button,
             dead_button,win_button]

Label button group

    choose_buttons=[player_button_1,player_button_2]

Introduction to the image group of button functions

    button_info_dict={none_button:none_info,pve_button:pve_info,pvp_button:pvp_info,
                      endless_button:endless_info,control_button:control_info,
                      memory_button:record_info,cooling_button:cooling_info}
    #当前显示的图像列表
    info_label=[]
    #存储模拟刚体运动的列表
    rigidbody_list=[]
    #玩家实例,初始化为战士
    player_1=live.MonkeyKing(setting,screen)
    player_2=live.MonkeyKing(setting,screen)

    if not os.path.exists(setting.record_path):
        #如果游戏记录文件不存在就新创建一个
        with open(setting.record_path,'w',newline="") as f:
            writer=csv.writer(f)
            header=["Time","Mode","Winner","1st Score","2st Score","Duration(s)","1st Player","2nd Player","isCooling"]
            writer.writerow(header)

Game main loop

    while True: 
        #绘制背景
        screen.blit(setting.screen_surface_background,(0,0))
        #设置游戏帧率
        clock.tick(setting.fps)
        #检测键盘鼠标事件   
        game_event.check_event(setting,screen,group_player,group_attack,group_enemy,
                               group_enemy_attack,buttons,showinfo,button_info_dict,info_label)

Update the label of the currently selected character

        game_event.update_choose(setting,buttons,choose_buttons)

        if (setting.game_active and (setting.game_mode==0 or setting.game_mode==2)):

                    group_player.add(player_2)                
                setting.isinit=True
            #游戏计时器
            setting.timer+=1
            #更新玩家
            group_player.update()
            #生成敌人
            game_event.generate_enemies(setting,group_enemy,screen)

Update enemies, player attacks, enemy attacks, player status, etc.

game_event.update_enemies(setting,showinfo,screen,group_player,group_enemy,group_attack,group_enemy_attack)

            if setting.isinit and ((setting.player_1!=None and setting.health_1<=0) or (setting.player_2!=None and setting.health_2<=0)):              
                game_event.game_dead(setting,showinfo,group_enemy,group_attack,group_enemy_attack)

                if setting.player_1!=None and setting.player_2!=None:
                    player_1=setting.player_1
                    group_player.add(player_1)
                    player_2=setting.player_2
                    group_player.add(player_2)                        
                    setting.isinit=True

Game timer

setting.timer+=1

Update player

            player_1.update()
            player_2.update()

Update player's attack, information display and physical simulation

game_event.update_attacks_pvp(setting,screen,group_attack,rigidbody_list)
            game_event.update_state(setting,showinfo)
            game_event.update_rigidbody(setting,rigidbody_list)

Player 1 victory condition

            if setting.isinit and setting.health_2<=0:
                setting.score_1+=1
                game_event.game_win(setting,showinfo,group_enemy,group_attack,group_enemy_attack)
                setting.timer=0

                game_event.game_win(setting,showinfo,group_enemy,group_attack,group_enemy_attack)
                setting.timer=0

Draw the entire game window based on the results of the above update

        game_event.update_screen(setting,screen,group_player,group_attack,group_enemy,group_enemy_attack,
                                 showinfo,buttons,info_label,choose_buttons)
