[SOLVED] Display text on block like signs

Update : 

I've managed to store the value of my text field in the block in an nbtTag, but now how do I display it on the block ?

I checked this option : 

The final procedure who launched when the player click on button "Validate" :

Hello,

After a few tests, I've found a way to display text on a block. Here's how to do it (for anyone else wondering):

This procedure requires manual modifications of the files generated by MCreator (and a good knowledge of JAVA and minecraft modding):

3) Create a new class implementing BlockEntityRenderer<? extends BlockEntity> in a package named “renders”, for example. The render() method is used to configure the text display.

public class SignCityBlockRenderer implements BlockEntityRenderer<SignCityBlockBlockEntity> { // SignCityBlockBlockEntity is the class name of my custom block entity

	private final Font font;
	private final BlockEntityRendererProvider.Context context;

	public SignCityBlockRenderer(BlockEntityRendererProvider.Context context) {
		this.context = context;
		this.font = context.getFont();
	}

	@Override
	public void render(SignCityBlockBlockEntity blockEntity, float partialTicks, PoseStack poseStack, MultiBufferSource buffer, int combinedLight, int combinedOverlay) {
		String text = blockEntity.getCustomText();

		 if (text == null || text.isEmpty()) return;
		
		// Here you can put your custom code to display the text (color, size...)
		
	}

4) In the mod's main class (with the @Mod annotation), insert these lines: 
 

// Start of user code block mod init
if (FMLEnvironment.dist == Dist.CLIENT) {
	modEventBus.addListener(this::registerEntityRenderers);
}
// End of user code block mod init

5) Still in the main class,  insert these lines: 
 

// Start of user code block mod methods
private void registerEntityRenderers(EntityRenderersEvent.RegisterRenderers event) {
    System.out.println("[DEBUG] registerEntityRenderers called");
    event.registerBlockEntityRenderer(
        MoreroadsModBlockEntities.SIGN_CITY_BLOCK.get(), // This is your bloc entity
        SignCityBlockRenderer::new // This is your custom class who implements 
        						   //BlockEntityRenderer
    );
}
// End of user code block mod methods

6) Check that all imports into modified classes are correct
