【Lua实战】坐骑喂养：属性成长的线性提升与上限封顶实现

local function feedOnce(actor)
    local player = class(actor)
    local growth = tonumber(getplayvar(actor, 2, "MOUNT_GROW") or "0")
    if growth >= 100 then
        sendmsg(actor, 0, "坐骑已喂养至满级，可改喂外观饲料")
        return false
    end
    if player:checkitemw("精饲料", 1) == false then
        sendmsg(actor, 0, "精饲料不足，马厩有售5000金币一袋")
        return false
    end
    player:takeitem("精饲料", 1)
    local next = math.min(100, growth + 0.5)
    setplayvar(actor, "HUMAN", "MOUNT_GROW", next, 1)
    sendmsg(actor, 0, "喂养成功，成长" .. next .. "/100")
    return true
end

local function checkStage(actor, growth)
    local stage = math.floor(growth / 20)
    local got = tonumber(getplayvar(actor, 2, "MOUNT_STAGE") or "0")
    if stage > got then
        setplayvar(actor, "HUMAN", "MOUNT_STAGE", stage, 1)
        sendmail(actor, 0, "坐骑阶段奖励", "成长达到" .. stage * 20 .. "点", "坐骑外观箱|1")
    end
