DPS Tracker

[Xikini]

Main function here is the DPS Tracking.

I included a tester function to just print to console..
but maybe you can send the information to the client, and have it update there for the player..
or attach it to a specific monster, like a training dummy, and let players see their dps.

Use it however you like. lol

local DPS_dropoff = 60 -- seconds (damage beyond 60 seconds, is removed)

local dpsChart = {
--    [playerId] = {
--        totalDPS = 0,
--        damageChart = {
--            {damage = 0, timestamp = os.mtime()},
--            {damage = 0, timestamp = os.mtime()},
--            {damage = 0, timestamp = os.mtime()}
--        }
--    }
}


local function updateDPSChart(playerId, newDamage)
    if not dpsChart[playerId] then
        dpsChart[playerId] = {totalDPS = 0, damageChart = {}}
    end
    local currentTime = os.mtime()
    while #dpsChart[playerId].damageChart > 0 and (dpsChart[playerId].damageChart[1].timestamp + (DPS_dropoff * 1000)) < currentTime do

        table.remove(dpsChart[playerId].damageChart, 1)
    end
    if newDamage then
        dpsChart[playerId].damageChart[#dpsChart[playerId].damageChart + 1] = {damage = newDamage, timestamp = currentTime}
        dpsChart[playerId].totalDPS = dpsChart[playerId].totalDPS + newDamage

    end
    timeSpanSeconds = math.max(timeSpanSeconds, 1)
    return math.floor(dpsChart[playerId].totalDPS / timeSpanSeconds)
end

function healthChange.onHealthChange(creature, attacker, primaryDamage, primaryType, secondaryDamage, secondaryType, origin)

local eventCallback = EventCallback

function eventCallback.onSpawn(creature, position, startup, artificial)
    creature:registerEvent("onHealthChange_DPS_Tracker")
    return true
end

-- example usage, where we ping to console every second
local function pingDPS(playerId)
    local player = Player(playerId)
    if not player then
        return

    print("Current DPS: " .. getDPS(playerId))

@Xikini great script, thanks for sharing. Just one detail I recently learned: if you want to turn a number positive, just use math.abs(x)

Working perfectly! Great Xikini! Great!
