想做一个这样的技能：猛虎：出牌阶段，你可以选择任意一名角色拼点，若你赢，则这回合内，你每对其他角色造成一点伤害，你摸一张牌，若你输，则你立刻失去一点体力；每回合限用一次。
用的版本是alpha版，其他的都实现了就是“每回合限用一次”这个.....
x_menghu_card = sgs.CreateSkillCard{ name="x_menghu_card",
target_fixed=false,
will_throw=false,
filter = function(self, targets, to_select, player) if #targets > 0 then return false end

if to_select:objectName() == player:objectName() then return false end
if to_select:isKongcheng() then return false end return true end,
on_use = function(self, room, source, targets)
if source:hasFlag("menghu_used") then return nil end
local room = source:getRoom()
local target = targets[1]
local success = source:pindian(target, "x_menghu_card", Null)
source:setFlags("menghu_used")
if success then
source:setFlags("menghu_success")
else
room:loseHp(source,1)
end
end,}
x_menghu_vs = sgs.CreateViewAsSkill{
name="x_menghu_vs",
n=0,
view_filter=function(self,selected,to_select)
return false
end,
view_as = function(self, cards)
return x_menghu_card:clone()
end,
enabled_at_play = function(self,player)
return not player:hasFlag("menghu_used")
end,
}
x_menghu = sgs.CreateTriggerSkill{
name = "x_menghu",
view_as_skill = x_menghu_vs,
events = {sgs.Damage},
frequency = sgs.Skill_NotFrequent,
on_trigger = function(self, event, player, data)
local room = player:getRoom()
local damage = data:toDamage()
if event == sgs.Damage and damage.from:hasSkill(self:objectName()) and player:hasFlag("menghu_success") then
for var = 1, damage.damage, 1 do
player:drawCards(1)
end
end
end
}


怎么这么乱啊

room:setPlayerFlag(source, "menghu_used")
或者
sgs.Self:setFlags("menghu_used")
