Custom Hud elements

[DakiLLa]

hello guys, i want to make my own hud elements and i started from health bar. Well, everything is going good but i have one problem. How do i make that red line will show my current health percentage? I know, it requires some math skills but i have no any ideas... Anybody can help me? Here is a little piece of code ofcourse.

addEventHandler( 'onClientRender', gRoot,
function()
local scX, scY = guiGetScreenSize();
local lineX = scX/1.1725;
local lineEndX = scX/1.053;
local lineY = scY/6.5;
 
dxDrawLine( lineX, lineY, lineEndX, lineY, tocolor( 0, 0, 0, 255 ), 17 );
dxDrawLine( lineX+5, lineY, lineEndX-5, lineY, tocolor( 150, 0, 0, 255 ), 9 );
dxDrawLine( lineX+5, lineY, lineEndX-5, lineY, tocolor( 255, 0, 0, 255 ), 9 );
end
);

So it looks like:

Thx in advance

This, to be honest, is math of the kind a 13 year old can do...

"Ending point" X = Offset for X + (Max width / 100 * current health)

Assuming 100 is the actual maximum, of course.

First thing you need to know is Max length of the health bar (when health is full). Then, you need to calculate what percentage of health player currently have (getElementHealth divided by max health(eg.100)). Once you get the percentage, multiply that number by max health bar length and you will get the length of the health bar to show.

This is very simple math:

maxBarLength = 100;
maxHealth = 100;
 
local percentage = getElementHealth( player ) / maxHealth; -- between 0 and 1
local currentBarLength = percentage * maxHealth; -- length of the bar to display

Have you just been busy with PHP maybe?

Since you use the ";" tags at the end haha.

No, I've been busy with other programming languages (C#, ActionScript and MAXScript) and it's just fine to use semicolons in Lua, so I don't care

well, thx a lot for your help, ive resolved this problem by the next way: ive divided width of bar by 1000 and multyplied it with current health.

local hp = ( hp_Width / 1000 )*getElementHealth( gMe );
