I intend to generate a hollow square with dimensions of 2x2 at the player's feet, providing a visual range indicator for the player.

However, it is not working in the game. The code is shown below.

private Tesselator tesselator = new Tesselator();
    private boolean isBuildLine = true; 
    @SubscribeEvent
    public void drawRectangle(TickEvent.PlayerTickEvent event) {
        LocalPlayer player = Minecraft.getInstance().player;
        LevelRenderer levelRenderer = Minecraft.getInstance().levelRenderer;
        if (player != null && isBuildLine) {
            isBuildLine = false;
            BufferBuilder builder = tesselator.getBuilder();
            builder.begin(VertexFormat.Mode.LINES, DefaultVertexFormat.POSITION_COLOR);

            // Calculated position
            double playerX = player.getX();
            double playerY = player.getY();
            double playerZ = player.getZ();
            double footY = playerY - player.getEyeHeight();

            builder.vertex(playerX - 1, footY, playerZ - 1).color(216, 59, 1, 0).endVertex();
            builder.vertex(playerX + 1, footY, playerZ - 1).color(216, 59, 1, 0).endVertex();

            builder.vertex(playerX + 1, footY, playerZ - 1).color(216, 59, 1, 0).endVertex();
            builder.vertex(playerX + 1, footY, playerZ + 1).color(216, 59, 1, 0).endVertex();

            builder.vertex(playerX + 1, footY, playerZ + 1).color(216, 59, 1, 0).endVertex();
            builder.vertex(playerX - 1, footY, playerZ + 1).color(216, 59, 1, 0).endVertex();

            builder.vertex(playerX - 1, footY, playerZ + 1).color(216, 59, 1, 0).endVertex();
            builder.vertex(playerX - 1, footY, playerZ - 1).color(216, 59, 1, 0).endVertex();


            tesselator.end();
            isBuildLine = true;
        }
    }
