	public static void renderName(Entity entity, String string, int distance, float partialTicks)
{
	RenderManager renderManager = Minecraft.getMinecraft().getRenderManager();
	Entity player = Minecraft.getMinecraft().getRenderViewEntity();
	FontRenderer fontRenderer = renderManager.getFontRenderer();
	Tessellator tessellator = Tessellator.getInstance();
	WorldRenderer worldRenderer = tessellator.getWorldRenderer();

	double d3 = Utils.getDistanceBetweenBlocks(player.getPosition(), entity.getPosition());

	if (d3 <= (double)(distance))
	{
		float scale = (float) (0.016666668F * getDistanceScalled(d3));
		int string_length = fontRenderer.getStringWidth(string) / 2;

		double playerX = player.lastTickPosX + (player.posX - player.lastTickPosX);
		double playerY = player.lastTickPosY + (player.posY - player.lastTickPosY);
		double playerZ = player.lastTickPosZ + (player.posZ - player.lastTickPosZ);
		double entityX = entity.lastTickPosX + (entity.posX - entity.lastTickPosX);
		double entityY = entity.lastTickPosY + (entity.posY - entity.lastTickPosY);
		double entityZ = entity.lastTickPosZ + (entity.posZ - entity.lastTickPosZ);
		double diffX = entityX - playerX * (double) partialTicks;
		double diffY = entityY - playerY * (double) partialTicks;
		double diffZ = entityZ - playerZ * (double) partialTicks;

		GlStateManager.pushMatrix();

		GlStateManager.translate(diffX + 0.0D, diffY + (entity.height + 0.75D), diffZ);
		GlStateManager.rotate(-player.rotationYaw, 0.0F, 1.0F, 0.0F);
		GlStateManager.rotate(player.rotationPitch, 1.0F, 0.0F, 0.0F);
		GlStateManager.scale(-scale, -scale, scale);

		GlStateManager.depthMask(false);
		GlStateManager.disableTexture2D();
		GlStateManager.disableLighting();
		GlStateManager.disableBlend();

		Minecraft.getMinecraft().ingameGUI.drawRect(-string_length - 2, -2, fontRenderer.getStringWidth(string) + 1 -string_length, fontRenderer.FONT_HEIGHT, 0x50000000);
		Minecraft.getMinecraft().ingameGUI.drawRect(-string_length - 1, -1, fontRenderer.getStringWidth(string) -string_length, fontRenderer.FONT_HEIGHT - 1, 0x50FF0000);
		fontRenderer.drawString(string, -string_length, 0, -1);

		GlStateManager.enableTexture2D();
		GlStateManager.enableLighting();
		GlStateManager.disableBlend();
		GlStateManager.depthMask(true);

		GlStateManager.popMatrix();
	}
}

 

I use in public void onRenderLiving(RenderLivingEvent.Post event).

Hi,

 

I want to draw a nametag on a given position in the World:

 

 

	

/**
* x,y,z the Position(BlockPos)
* string, the String to render
*/

public static void renderName(double x, double y, double z, String string, float partialTicks){

	RenderManager renderManager = Minecraft.getMinecraft().getRenderManager();
	Entity player = Minecraft.getMinecraft().thePlayer;
	FontRenderer fontRenderer = renderManager.getFontRenderer();
	//Tessellator tessellator = Tessellator.getInstance();

	//float scale = (float) (0.016666668F * getDistanceScalled(d3));
	int string_length = fontRenderer.getStringWidth(string) / 2;

	double playerX = player.lastTickPosX + (player.posX - player.lastTickPosX);
	double playerY = player.lastTickPosY + (player.posY - player.lastTickPosY);
	double playerZ = player.lastTickPosZ + (player.posZ - player.lastTickPosZ);

	double diffX = x - playerX * (double) partialTicks;
	double diffY = y - playerY * (double) partialTicks;
	double diffZ = z - playerZ * (double) partialTicks;

	GlStateManager.pushMatrix();

	GlStateManager.translate(diffX, diffY + 2D, diffZ);
	GlStateManager.rotate(-player.rotationYaw, 0.0F, 1.0F, 0.0F);
	GlStateManager.rotate(player.rotationPitch, 1.0F, 0.0F, 0.0F);
	//GlStateManager.scale(-scale, -scale, scale);

	GlStateManager.depthMask(false);
	GlStateManager.disableTexture2D();
	GlStateManager.disableLighting();
	GlStateManager.disableBlend();

	//Minecraft.getMinecraft().ingameGUI.drawRect(-string_length - 2, -2,fontRenderer.getStringWidth(string) + 1 - string_length, fontRenderer.FONT_HEIGHT, 0x50000000);
	//Minecraft.getMinecraft().ingameGUI.drawRect(-string_length - 1, -1,fontRenderer.getStringWidth(string) - string_length, fontRenderer.FONT_HEIGHT - 1, 0x50FF0000);
	fontRenderer.drawString(string, -string_length, 0, -1);

	GlStateManager.enableTexture2D();
	GlStateManager.enableLighting();
	GlStateManager.disableBlend();
	GlStateManager.depthMask(true);
	GlStateManager.popMatrix();
}

 

 

The problem is, that the string is buzzing around and other self definded things to render are gray now... Whats the mistake?
