This code is like the two image split for the ammo and health icons in ep1 (near the cross hair) but does it on an angle both on the left side and right side.
This uses alot of trig and the code could be simplified a bit.

Code

This assumes you already have a HUD panel set up and ready to use. First thing to do is to define the two images:

Header: 

private:
	CHudTexture	*m_icon_rb;		// right bracket, full
	CHudTexture	*m_icon_lb;		// left bracket, full

Constructor: 

	m_icon_lb = gHUD.GetIcon( "health_full" );
	m_icon_lbe = gHUD.GetIcon( "health_empty" );

The names here refer to the textures defined in mod_textures.txt

Once we have this we need to add some code to the paint function: 

	int scaledW, scaledH, scaledDis, screenWide, screenTall, X1,Y1, X2, offset;

	offset = scheme()->GetProportionalScaledValue(100);
		
	//image width
	scaledW = scheme()->GetProportionalScaledValue(25);

	//image height
	scaledH = scheme()->GetProportionalScaledValue(100);

	//image indentation
	scaledDis = scheme()->GetProportionalScaledValue(200);

	GetHudSize(screenWide, screenTall);

	X = screenWide/2 - scaledDis - scaledW;
	Y = screenTall/2 - scaledH/2;

	m_icon_lbe->DrawScew_Left(X, Y, scaledW, scaledH, 1-HealthPer, true, offset);
	m_icon_lb->DrawScew_Left(X, Y, scaledW, scaledH, 1-HealthPer, false, offset);

This draws each element at pos X,Y with size scaledW, scaledH. Since these are health bars a health percentage is already defined. The true/false refers to which image they are (true for empty image and false for full) and the offset is the horizontal distance between the edge and the pivot point (see picture above).

We need to add the new functions into hud.cpp/hud.h
For the header add: 

	void DrawScew_Left(int x, int y, int w, int h, float per, bool isTop, int offset) const;
	void DrawScew_Right(int x, int y, int w, int h, float per, bool isTop, int offset) const;

And the cpp file add: 


void CHudTexture::DrawScew_Left(int tx, int ty, int tw, int th, float per, bool isTop, int offset) const
{
	per = max(0, min(1,per));

	vgui::surface()->DrawSetTexture( textureId );
	vgui::surface()->DrawSetColor( Color(125,125,125,125) );

	float x = (float)(tx);
	float y = (float)(ty);
	float w = (float)(tw);
	float h = (float)(th);

	if (!(per > 99 || per < 0))
	{
		float sy = y+h-(per*h);
		float sx = x+w;
