Help making code efficient and simplifying XP and levelling

[lewiso574]

Hi. Recently i have been trying to implement XP and levelling into the gamemode i am creating. I am able to assign the player their level as well as give them XP for doing damage to enemies which is currently damage done divided by two.

Basically the code works well however it is not very efficient meaning i will have to write hundreds of lines of code for each level doing it this way.

Does anyone have and ideas on how i can simplify this process and make the code more efficient?

Here is the xp values for each level

lvl1 = 0
lvl2 = 83 
lvl3 = 174 
lvl4 = 276 
lvl5 = 388 
lvl6 = 512 
lvl7 = 650 
lvl8 = 801 
lvl9 = 969 
lvl10 = 1154 
lvl11 = 1358 
lvl12 = 1584 
lvl13 = 1833 
lvl14 = 2107 
lvl15 = 2411 
lvl16 = 2746 
lvl17 = 3115 
lvl18 = 3523 
lvl19 = 3973 
lvl20 = 4470 
lvl21 = 5018 
lvl22 = 5624 
lvl23 = 6291 
lvl24 = 7028 
lvl25 = 7842 
lvl26 = 8740 
lvl27 = 9730 
lvl28 = 10824 
lvl29 = 12031 
lvl30 = 13363 

This code is then using these values and checking them against their XP and tells me if they are above the level.
If i was to do this for every level as well as assign the player the actual level too. It would require a lot of lines of code. Is there a simpler way to do this?

function meta:addgunxp(amount)
	local currentxp = self:getgunxp()
	self:setgunxp( currentxp + amount )
end

function meta:setgunxp(amount)
	self:SetNetworkedInt( "gunxp", amount )
	self:savexp()
end

function meta:getgunxp()
	return self:GetNetworkedInt("gunxp")

end

function meta:checkxp()
	local currentxp = self:getgunxp()
	if currentxp > lvl1 then self:ChatPrint("above level 1") elseif currentxp > lvl20 then self:ChatPrint("above level 20")  end
end

function meta:savexp()
local xp = self:getgunxp()
 self:SetPData("gunxp", xp)
end

Try something like this
[LUA]
local levels = {
[1] = 0,
[2] = 83,
[3] = 174,
[4] = 276,
[5] = 388,
[6] = 512,
[7] = 650,
[8] = 801,
[9] = 969,
[10] = 1154,
[11] = 1358,
[12] = 1584,
[13] = 1833,
[14] = 2107,
[15] = 2411,
[16] = 2746,
[17] = 3115,
[18] = 3523,
[19] = 3973,
[20] = 4470,
[21] = 5018,
[22] = 5624,
[23] = 6291,
[24] = 7028,
[25] = 7842,
[26] = 8740,
[27] = 9730,
[28] = 10824,
[29] = 12031,
[30] = 13363
}

function meta:checkxp()
local currentxp = self:getgunxp()
local lastLevel = 0
for k,v in pairs(levels) do
if currentxp > v then
lastLevel = k
else
break
end
end

self:ChatPrint("above level "..lastLevel)
end
[/LUA]

This looks promising. I'll give it a go, thank you very much.

Welcome, glad i could help.

Also advice you should use Get/SetNWInt instead of Get/SetNetworkedInt because Get/SetNetworkedInt is deprecated

You're better off using a formula to calculate the experience.

I found the best model for your leveling up experience to be:

f(x)=(x*3.77)^2

You can see Desmos thinks so too:

Your next step would be to create the function as a Lua function, something along the lines of...

function getLevelExperience( level )
    return ( level * 3.77 ) ^ 2
end

function getLevelBounds( level )
    -- min, max
    return getLevelExperience( level ), getLevelExperience( level + 1 )
end
