            end 

Why don't appear anything in the screen? It is anything wrong?

[JR10]

Where is screenWidth and screenHeight defined? You need to add dxDrawRectangle to onClientRender event.

The argument in getElementAlpha is wrong, supposed to be an element.

[drk]

Ah,

    local screenWidth, screenHeight = guiGetScreenSize() 

and it is on onClientRender event. I will solve getElementAlpha problem .

[JR10]

math.floor(256-256*(health)) 

What is that? 0*health, so it will always return zero.

[drk]

I've solved the problem but the bar not appear.

[JR10]

Show your code now.
