what does this output?

Judging by the error he posted - it returns nil.

@boro:

Where and how is the variable v defined?

[boro]

i have v defined check it

for _, v in ipairs ( getElementsByType ( "ped" ) ) do 
if ( getElementModel ( v ) == 281 ) then 
local x, y, z = getElementPosition( v ) 
if isElementOnScreen( v ) then 
local X, Y = getScreenFromWorldPosition( x, y, z ) 
if X then 
dxDrawRectangle( X - 30, Y - 20, 60, 10, tocolor( 0, 0, 0, 120) ) 
local health = exports["extra_health"]:getElementExtraHealth(v) 
local lineLength = 56 * ( health / 100 ) 
dxDrawRectangle( X - 28, Y - 18, lineLength, 6, tocolor( 255, 0, 0, 100 ) )

outputChatBox(tostring(health)) 
  

what does this output?

chatbox say nill

[Anubhav]

That means you din't set extra health to it?

[Dealman]

Try this, what does it output?

local health = exports["extra_health"]:getElementExtraHealth(v) 
outputChatBox("Value: ["..tostring(v).."]") 

Edit:

Are you absolutely sure the resource "extra_health" is running? It has to be running for it to work.

[boro]

It show this

Value: [userdata: 000000A9]

And yes i have set extrahealth to 10000 and work it good

[boro]

oh resolved

i rename resource name and now it work good

But Ty all.
