how to use math.approach?

[TheCodingBoss]

i was trying to add a script that automatically regenerates health, ive seen people use math.approach but i cant really get it, this doesnt work and i dont know when to call it

function regenhealth(ply)
local health = ply:Health()
local maxhealth = 100
local speed = 200

if health < 100 then
 health = math.Approach( health, maxhealth, speed * FrameTime() )
     end
end

You'll need to call ply:SetHealth( health ) afterwards.

You need to use it in a Think hook, here is an example;

[lua]local speed = 67
local health

local GetMaxHealth, Health, SetHealth, player, FrameTime = GetMaxHealth, Health, SetHealth, player, FrameTime

hook.Add("Think", "kden", function()
for k,v in pairs(player.GetAll()) do
health = v:Health()

if (health < v:GetMaxHealth()) then
health = math.Approach(health, v:GetMaxHealth(), (speed * FrameTime()))
v:SetHealth(health)
end
end
end)[/lua]

It regenerates fast depending on your tickrate. Right now the minimum speed is 67, because the tickrate is 66 (for me that is), however, if your server has tickrate 33, you could try to set the speed to 34. Still, it would regenerate very fast, so I'd suggest using timers to regenerate instead depending on how fast you want it to actually regenerate.

ok how would i find the tickrate

I'd suggest you use the PlayerTick hook actually.
You can use engine.TickInterval to get the delay between ticks but really all you need is the PlayerTick hook and the FrameTime function.

hook.Add( "PlayerTick", "My foooadaa", function( ply )
    ply:SetHealth( math.Approach( ply:GetHealth(), 100, 10 * FrameTime() ) )
end )

This example increases the player's health by 10 per second i hope
