这是我在lua中玩的一个小游戏，伤害是一个math.random。但当我把让玩家攻击的函数放在一个如果它不再是随机的。
它的作用如下：攻击敌人，造成22点伤害！当前敌人生命值为78敌人准备进攻！敌人对你造成19点伤害！你目前的健康状况是81袭击
攻击敌人，造成22点伤害！当前敌人生命值为78敌人准备进攻！敌人对你造成19点伤害！你目前的健康状况是81袭击
攻击敌人，造成22点伤害！当前敌人生命值为78敌人准备进攻！敌人对你造成19点伤害！你目前的健康状况是81袭击
正如你所看到的，它不是随机的，有什么修复方法吗？
math.randomseed(os.time())
player_attacked = 0
enemy_attack_time = 0
enemy_attack = 0
player = {}
player.health = 100
player_health = player.health
player.damage = math.random(0,25)
player_damage = player.damage
enemy = {}
enemy.health = 100
enemy_health = enemy.health
enemy.damage = math.random(5, 30)
enemy_damage = enemy.damage
function player.init_attack()
print('Attack? ')
wanna_attack = io.read()
if wanna_attack == 'y' then
print('Attacked enemy with '..player_damage..' damage! current enemy health is '..enemy_health - player_damage)
else
os.exit()
end
player_attacked = 1
end
function enemy.init_attack()
print('Enemy Attacked you with '..enemy_damage..' damage! your current health is '..player_health - enemy_damage)
if player_health <= 0 then
os.exit()
end
end
player.init_attack()
if player_attacked == 1 then
print('Enemy getting ready to attack!')
enemy.init_attack()
player_attacked = 0
end
while player_health ~= 0 or enemy_health ~= 0 do
player.init_attack()
if player_attacked == 1 then
print('Enemy getting ready to attack!')
enemy.init_attack()
player_attacked = 0
end
end
OP代码将player.damage和enemy.damage值设置为随机值一次，但该随机值从未更改。
为了解决这个问题，代码必须找到每次命中时调用random的方法。一种解决方案是设计一个新的函数player.hit，它可以获得一个随机伤害值，并将其应用于敌人的健康，从函数调用中返回伤害值。这可能是什么样子：
-- Player
player = {}
player.health = 100
player.hit = function ()
local damage = math.random(0,25)
enemy.health = enemy.health - damage
return damage
end
最好使用一个表构造函数来完成此操作，如下所示：
-- Enemy
enemy = {
health = 100,
hit = function ()
local damage = math.random(5, 30)
player.health = player.health - damage
return damage
end
}
现在，剩下的代码需要修改为使用函数player.hit和enemy.hit，以及现在通过调用.hit函数修改的player.health和enemy.health：
function player.init_attack()
print('Attack? ')
wanna_attack = io.read()
if wanna_attack == 'y' then
print('Attacked enemy with '.. player.hit() ..' damage! current enemy health is '.. enemy.health)
else
os.exit()
end
player_attacked = 1
end
function enemy.init_attack()
print('Enemy Attacked you with '.. enemy.hit() ..' damage! your current health is '.. player.health)
if player.health <= 0 then
os.exit()
end
end
-- ...
while player.health ~= 0 or enemy.health ~= 0 do
player.init_attack()
这是一个测试运行：

Attack?
y
Attacked enemy with 2 damage! current enemy health is 98
Enemy getting ready to attack!
Enemy Attacked you with 25 damage! your current health is 75

Attacked enemy with 20 damage! current enemy health is 38

Attacked enemy with 6 damage! current enemy health is 32

y
Attacked enemy with 13 damage! current enemy health is 19

Enemy Attacked you with 17 damage! your current health is -12
因为在初始化期间只执行player.damage = math.random(0,25)和enemy.damage = math.random(5, 30)一次，而不是针对每次攻击重复执行。
