Wait isnt the problem in here 

public static void drawTexturedQuadFit(double x, double y, double width, double height, double zLevel)
{
	caveman = caveman.getCaveman();
	Tessellator tessellator = Tessellator.instance;
	if(caveman != null)
	{
		for(int i = 0; i < caveman.func_110138_aP(); i++)
		{
			if(caveman.func_110138_aP() > i)
			{
				tessellator.startDrawingQuads();
				tessellator.setColorOpaque(0, 255, 0);
				tessellator.addVertexWithUV(x + 0, y + height, zLevel, 0, 1);
				tessellator.addVertexWithUV(x + width, y + height, zLevel, 1, 1);
				tessellator.addVertexWithUV(x + width, y + 0, zLevel, 1, 0);
				tessellator.addVertexWithUV(x + 0, y + 0, zLevel, 0, 0);
				tessellator.setColorOpaque(0, 255, 0);
				tessellator.draw();
			}
			else
			{
				tessellator.startDrawingQuads();
				tessellator.setColorOpaque(255, 0, 0);
				tessellator.addVertexWithUV(x + 0, y + height, zLevel, 0, 1);
				tessellator.addVertexWithUV(x + width, y + height, zLevel, 1, 1);
				tessellator.addVertexWithUV(x + width, y + 0, zLevel, 1, 0);
				tessellator.addVertexWithUV(x + 0, y + 0, zLevel, 0, 0);
				tessellator.setColorOpaque(255, 0, 0);
				tessellator.draw();
			}
		}
	}
}

 

Because before I added that it was working

Heres my code. but yeah I think I copied everything: 

	private Timer timer;

public void HealthBarRenderer()
{
	Field[] fields = Minecraft.getMinecraft().getClass().getDeclaredFields();
	for(Field field : fields)
	{
		if(field.getType().isAssignableFrom(Timer.class))
		{
			field.setAccessible(true);
			try
			{
				timer = (Timer) field.get(Minecraft.getMinecraft());
			}
			catch(IllegalArgumentException e)
			{
				e.printStackTrace();
			}
			catch(IllegalAccessException e)
			{
				e.printStackTrace();
			}
		}
	}
}

	float healthHeight = 2.0f;//and its height
	EntityPlayer p = Minecraft.getMinecraft().thePlayer;
	double diffX = e.prevPosX + interp * (e.posX - e.prevPosX) - (p.prevPosX + interp * (p.posX - p.prevPosX));

  Quote
public void HealthBarRenderer()

originally was

  Quote
public HealthBarRenderer()

meaning its the constructor

 

this constructor was suppose to set the timer to somethign so that shit renders well

 

please copy the WHOLE class and register it

to future reader, this is the final version of my health displayer, feel free to use it and change ForgeRevCommonProxy.blankTexture to a white texture 1x1

 

  Reveal hidden contents

 

well start by usign a white 1x1 texture, after that adding a border wouldn't be hard (and you can always surround everythign with a if(entity instanceof Caveman) if you dotn want to render the other entities the same way
