Is there any way to add a name tag-type-thing to a block, where the name hovers over it? How would I do so?

 

Note: I would like to be able to do this to any block, even vanilla ones

 

Thanks

1) Where would I get the instance of the block that should have a name tag?

2) Do I need to make a new renderer that renders name tags for blocks?

Where do I render the name tag, in the event?

So I copy pasted the renderLivingLabel from Render and tweaked it for a block:

FontRenderer fontrenderer = Minecraft.getMinecraft().fontRendererObj;
				int x = pos.getX();
				int y = pos.getY();
				int z = pos.getZ();
				RenderManager renderManager = Minecraft.getMinecraft().getRenderManager();
	            float f = 1.6F;
	            float f1 = 0.016666668F * f;
	            GlStateManager.pushMatrix();
	            GlStateManager.translate((float)x + 0.0F, (float)y + 1, (float)z);
	            GL11.glNormal3f(0.0F, 1.0F, 0.0F);
	            GlStateManager.rotate(-renderManager.playerViewY, 0.0F, 1.0F, 0.0F);
	            GlStateManager.rotate(renderManager.playerViewX, 1.0F, 0.0F, 0.0F);
	            GlStateManager.scale(-f1, -f1, f1);
	            GlStateManager.disableLighting();
	            GlStateManager.depthMask(false);
	            GlStateManager.disableDepth();
	            GlStateManager.enableBlend();
	            GlStateManager.tryBlendFuncSeparate(770, 771, 1, 0);
	            Tessellator tessellator = Tessellator.getInstance();
	            WorldRenderer worldrenderer = tessellator.getWorldRenderer();
	            int i = 0;

	            if (str.equals("deadmau5"))
	            {
	                i = -10;
	            }

	            int j = fontrenderer.getStringWidth(str) / 2;
	            GlStateManager.disableTexture2D();
	            worldrenderer.begin(7, DefaultVertexFormats.POSITION_COLOR);
	            worldrenderer.pos((double)(-j - 1), (double)(-1 + i), 0.0D).color(0.0F, 0.0F, 0.0F, 0.25F).endVertex();
	            worldrenderer.pos((double)(-j - 1), (double)(8 + i), 0.0D).color(0.0F, 0.0F, 0.0F, 0.25F).endVertex();
	            worldrenderer.pos((double)(j + 1), (double)(8 + i), 0.0D).color(0.0F, 0.0F, 0.0F, 0.25F).endVertex();
	            worldrenderer.pos((double)(j + 1), (double)(-1 + i), 0.0D).color(0.0F, 0.0F, 0.0F, 0.25F).endVertex();
	            tessellator.draw();
	            GlStateManager.enableTexture2D();
	            fontrenderer.drawString(str, -fontrenderer.getStringWidth(str) / 2, i, 553648127);
	            GlStateManager.enableDepth();
	            GlStateManager.depthMask(true);
	            fontrenderer.drawString(str, -fontrenderer.getStringWidth(str) / 2, i, -1);
	            GlStateManager.enableLighting();
	            GlStateManager.disableBlend();
	            GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);
	            GlStateManager.popMatrix();

 

But nothing shows up. I have declared pos and str elsewhere and I'm sure it's being called. What am I doing wrong?

Ah ok thanks, for all wondering, here is the final code:

FontRenderer fontrenderer = Minecraft.getMinecraft().fontRendererObj;
				EntityPlayer player = Minecraft.getMinecraft().thePlayer;
				double x = ((pos.getX() - player.posX) + 0.5) ;
				double y = ((pos.getY() - player.posY) + 0.5);
				double z = ((pos.getZ() - player.posZ) + 0.5);
				RenderManager renderManager = Minecraft.getMinecraft().getRenderManager();
	            float f = 1.6F;
	            float f1 = 0.016666668F * f;
	            GlStateManager.pushMatrix();
	            GlStateManager.translate((float)x + 0.0F, (float)y + 1, (float)z);
	            GL11.glNormal3f(0.0F, 1.0F, 0.0F);
	            GlStateManager.rotate(-renderManager.playerViewY, 0.0F, 1.0F, 0.0F);
	            GlStateManager.rotate(renderManager.playerViewX, 1.0F, 0.0F, 0.0F);
	            GlStateManager.scale(-f1, -f1, f1);
	            GlStateManager.disableLighting();
	            GlStateManager.depthMask(false);
	            GlStateManager.disableDepth();
	            GlStateManager.enableBlend();
	            GlStateManager.tryBlendFuncSeparate(770, 771, 1, 0);
	            Tessellator tessellator = Tessellator.getInstance();
	            WorldRenderer worldrenderer = tessellator.getWorldRenderer();
	            int i = 0;

	            if (str.equals("deadmau5"))
	            {
	                i = -10;
	            }

	            int j = fontrenderer.getStringWidth(str) / 2;
	            GlStateManager.disableTexture2D();
	            worldrenderer.begin(7, DefaultVertexFormats.POSITION_COLOR);
	            worldrenderer.pos((double)(-j - 1), (double)(-1 + i), 0.0D).color(0.0F, 0.0F, 0.0F, 0.25F).endVertex();
	            worldrenderer.pos((double)(-j - 1), (double)(8 + i), 0.0D).color(0.0F, 0.0F, 0.0F, 0.25F).endVertex();
	            worldrenderer.pos((double)(j + 1), (double)(8 + i), 0.0D).color(0.0F, 0.0F, 0.0F, 0.25F).endVertex();
	            worldrenderer.pos((double)(j + 1), (double)(-1 + i), 0.0D).color(0.0F, 0.0F, 0.0F, 0.25F).endVertex();
	            tessellator.draw();
	            GlStateManager.enableTexture2D();
	            fontrenderer.drawString(str, -fontrenderer.getStringWidth(str) / 2, i, 553648127);
	            GlStateManager.enableDepth();
	            GlStateManager.depthMask(true);
	            fontrenderer.drawString(str, -fontrenderer.getStringWidth(str) / 2, i, -1);
	            GlStateManager.enableLighting();
	            GlStateManager.disableBlend();
	            GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);
	            GlStateManager.popMatrix();
