【Lua实战】副本次数恢复道具：使用边界与次数校验的实现

local RESTORE_CAP = 1
function useRestoreTicket(actor)
    local player = class(actor)
    local used = tonumber(getplayvar(actor, 2, "RST_USED") or "0")
    if used >= RESTORE_CAP then
        sendmsg(actor, 0, "恢复道具每日限用1张")
        return
    end
    local left = tonumber(getplayvar(actor, 2, "FB_LEFT") or "0")
    if left > 0 then
        sendmsg(actor, 0, "当前还有" .. left .. "次进入机会，无需恢复")
        return
    end
    if player:checkitemw("次数恢复券", 1) == false then
        sendmsg(actor, 0, "缺少次数恢复券，商城有售800元宝")
        return
    end
    player:takeitem("次数恢复券", 1)
    setplayvar(actor, "HUMAN", "RST_USED", used + 1, 1)
    setplayvar(actor, "HUMAN", "FB_LEFT", left + 1, 1)
    sendmsg(actor, 0, "副本次数已恢复1次")
end

function resetDailyCounts(actor)
    local player = class(actor)
    setplayvar(actor, "HUMAN", "RST_USED", 0, 1)
    setplayvar(actor, "HUMAN", "FB_LEFT", 1, 1)
end
