Lerping A HUD Health Bar?

[Fillipuster]

Hey everyone.

After having worked with Glua for quite a while now, I've only recently gone in to making proper HUDs.

Therefore, I was wondering how one would go about lerping the health bar? - as seen on many HUDs.

I've tried a bunch of different things, yet nothing seems to do the job. Google doesn't help much either; only showing me lerps from one value to another. A health value would be dynamic all the time.

Any help is much appreciated :D

what do you mean by "A health value would be dynamic all the time."

Well, most of the examples that Google provides lerp say 0 to 100. I'd need to lerp X to X.

My problem is basically how I'd properly save the old health value and the new one. If I do this in HUDPaint, then it will override the old health value before the lerp has completed.

[QUOTE=Moat;52152104]Simply set the "to" argument for the lerp to the player's health divided by their max health. It'll return a number between 0 and 1, which you can use to multiply the max width of your health bars by.

Here's an example I posted a while ago:
[lua]

Fantastic! Thanks a lot Moat!
local color_blue = Color(0, 0, 100)
local color_blue_light = Color(0, 0, 255)
local healthbar_max_width = 200
local healthbar_cur_width = 0

hook.Add("HUDPaint", "DrawHealthBarTopLeftCorner", function()
local localplayer = LocalPlayer()
-- Lerps the current width to a number between 0 and 1 (health divided by max health)
healthbar_cur_width = Lerp(FrameTime() * 5, healthbar_cur_width, localplayer:Health() / localplayer:GetMaxHealth())

draw.RoundedBox(0, 10, 10, healthbar_max_width, 30, color_blue) --background for health bar

-- main health bar, width = max width multiplied by the lerp number (between 0 and 1)
draw.RoundedBox(0, 10, 10, healthbar_max_width * healthbar_cur_width, 30, color_blue_light)
end)
