Render Text in World

So I am wondering how to render text into the world, pretty much the same way like a name tag.

I found out that RenderWorldEvent.Pre/Post is never actually called, or is it?

So I tried using RenderWorldLastEvent.

Now ehen I try rendering, it does not really render, maybe the problem is, that RenderWorldLastEvent does not call it correctly, or my code is wrong.

@SubscribeEvent
    public void renderGameOverlayEvent(RenderWorldLastEvent event) {
        EntityPlayer player = mc.thePlayer;
        if (getItemPlayerIsLookingAt(player) != null) {
            if (getItemPlayerIsLookingAt(player) instanceof EntityItem) {
                EntityItem item = (EntityItem) getItemPlayerIsLookingAt(player);
                renderText(item, "heyyy )", item.posX, item.posY + 1, item.posZ, 64);
            }
        }

    }

The method gets called

This is only copied from the RenderEntity class

protected void renderText(Entity entity, String text, double x, double y, double z, int p_147906_9_) {
        renderManager = mc.getRenderManager();
        double d3 = entity.getDistanceSqToEntity(renderManager.livingPlayer);
        if (d3 <= (double) (p_147906_9_ * p_147906_9_)) {
            FontRenderer fontrenderer = renderManager.getFontRenderer();
            float f = 1.6F;
            float f1 = 0.016666668F * f;
            GlStateManager.pushMatrix();
            GlStateManager.translate((float) x + 0.0F, (float) y + entity.height + 0.5F, (float) z);
            GL11.glNormal3f(0.0F, 1.0F, 0.0F);
            GlStateManager.rotate(-this.renderManager.playerViewY, 0.0F, 1.0F, 0.0F);
            GlStateManager.rotate(this.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();
            byte b0 = 0;


            GlStateManager.disableTexture2D();
            worldrenderer.startDrawingQuads();
            int j = fontrenderer.getStringWidth(text) / 2;
            worldrenderer.setColorRGBA_F(0.0F, 0.0F, 0.0F, 0.25F);
            worldrenderer.addVertex((double) (-j - 1), (double) (-1 + b0), 0.0D);
            worldrenderer.addVertex((double) (-j - 1), (double) (8 + b0), 0.0D);
            worldrenderer.addVertex((double) (j + 1), (double) (8 + b0), 0.0D);
            worldrenderer.addVertex((double) (j + 1), (double) (-1 + b0), 0.0D);
            tessellator.draw();
            GlStateManager.enableTexture2D();
            fontrenderer.drawString(text, -fontrenderer.getStringWidth(text) / 2, b0, 553648127);
            GlStateManager.enableDepth();
            GlStateManager.depthMask(true);
            fontrenderer.drawString(text, -fontrenderer.getStringWidth(text) / 2, b0, -1);
            GlStateManager.enableLighting();
            GlStateManager.disableBlend();
            GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);
            GlStateManager.popMatrix();
        }
    }

Frankly, my knowledge about rendering is not the best, but there is no error when rendering and the game does not crash, but it is simply not getting rendered.
