Counter-Strike Basic Edition

An elite versus a gangster.

analyze

1. Define humans, describe public attributes life：100,name：姓名要传参
2. Define hero and terrorist classes
3. Define the main function to describe the gunfight process mainand create two objects
4. Define the grab method, which is divided into two methods Hero, Isboth
   • The defined method requires passing in the object being shot.
   • The health of the target being shot is reduced.
5. Call the grab operation in the main program
6. After the grab operation is started, everyone’s status information should be displayed in the main program
7. Define the method Personin the class __str__to display the status of each person
8. Set the opening and grabbing operation to be a repeated operation
   • Set the conditions for stopping the gunfight: one party’s health value <=0
   • Stop looping using break

Code

class Person:
    def __init__(self, name):
        self.name = name
        self.life = 100

    def __str__(self):
        return "%s当前生命值为：[%d]" % (self.name, self.life)


class Hero(Person):
    def fire(self, person):
        damage = 40
        print("%s向%s开抢，造成了[%d]伤害" % (self.name, person.name, damage))
        person.life -= damage


class Is(Person):
    def fire(self, person):
        damage = 90
        print("%s向%s开抢，造成了[%d]伤害" % (self.name, person.name, damage))
        person.life -= damage


def main():
    h = Hero("【英雄】")

        # 结束枪战
        if h.life <= 0:

            break

        # 结束枪战
        if is1.life <= 0:
            print("所有恐怖分子全部死亡，枪战结束")

9. Fixed hero information display mode and status description
   • 100: No damage
   • 70-99: Minor injury
   • 1-69: Serious injury
   • 0: hung up
10. Fix the problem of negative health value
    • When shooting, if the health value is < the damage value, the health value = 0, otherwise the health value will be reduced normally.
    • Ternary expression:变量 = 成立值 if 条件 else 不成立值

Counter-Strike Enhanced Edition

One elite versus three gangsters.

analyze

1. Create three terrorist objects, all three objects must be robbed, and all three objects must print status.
2. The end condition of the repair is that all three terrorists die, and all three terrorists die at the same time and
3. Solving the problem of robbing three terrorists
   • Random number: random
     1. Use random: add before all codesimport random
     2. Use random.randint(1, 3)to generate random numbers from 1 to 3
   • Generate a random number, judge it and shoot at that number of enemies

Code

Counter-Strike Super Enhanced Edition

analyze

1. Add gun shooting hit rate
2. Added gun damage value fluctuation
3. Added whip corpse text display effect
