【框架设计】职业克制：三职业的相性与平衡框架

---职业相性矩阵：攻击的克制系数
local AFFINITY = {
    warrior = { warrior = 1.0, mage = 1.15, taoist = 0.9 },
    mage    = { warrior = 0.9, mage = 1.0, taoist = 1.15 },
    taoist  = { warrior = 1.15, mage = 0.9, taoist = 1.0 },
}

function Combat.affinity(atkJob, defJob)
    local row = AFFINITY[atkJob]
    return (row and row[defJob]) or 1.0
end

---伤害结算的克制系数引入
function Combat.calcWithAffinity(atk, atkJob, defJob)
    local k = Combat.affinity(atkJob, defJob)
    return math.floor(atk * k)
end

---职业平衡的观测：对局胜率的矩阵
setontimerex(106, 3600)
function Balance.report()
    for atkJob, row in pairs(PvPStats.matrix) do
        for defJob, stat in pairs(row) do
            local rate = stat.win / math.max(stat.total, 1)
            if stat.total > 100 and (rate > 0.6 or rate < 0.4) then
                Ops.alert("职业失衡预警",
                    atkJob .. " vs " .. defJob,
                    string.format("%.0f%%", rate * 100))
            end
        end
    end
end
