Rendering Text via SpriteBatch

Hello,

I am trying to figure things out with Xenko, an my current goal would be to get a certain text appear on screen.

I am using BasicCameraController sync script from one of the example projects (1.9 engine version, of course), and adding some code I figured out from engine sources and documentation:

 public override void Update () {
        if (DefaultSpriteBatch == null)
            DefaultSpriteBatch = new SpriteBatch(Game.GraphicsDevice);
        if (DefaultFont == null)
            DefaultFont = Content.Load<SpriteFont>("XenkoDefaultFont");


        PrintString();
        ProcessInput();
        UpdateTransform();
    }

private void PrintString () {
            DefaultSpriteBatch.Begin(Game.GraphicsContext);
            DefaultSpriteBatch.DrawString(DefaultFont, "Whatever", new Vector2(0.5f, 0.5f), Color.Red);
            DefaultSpriteBatch.End();

        }

No text shows up on the screen. What am I doing wrong?

Hi @Petr_Dyachikhin

Welcome to the community.

You have to add a renderer to the Composition. This is covered in the Simple Sprite example in BallScript.cs.

Documentation doesn’t really explain this well. But they are working on it…

Hi,

Thanks, it actually works

Now, how do I make sure the text renders in foreground instead of behind all meshes?

Wow, your models must be really close to the camera

There are a bunch of options. Starting from the more complex option of setting up a multi-layer render composition. The simplest but possibly not the best option would be to call Begin with a depth stencil state, like

spriteBatch.Begin(context.GraphicsContext,depthStencilState:DepthStencilStates.None);

Nice, it works with depth stencil just fine, thank you.
I saw this stencil code in the engine sources, but did not know what it does. Now I know

Hello, I’m trying to do this as well, but the BallScript demo is gone (guessing it’s obsolete so even if I found it, it wouldn’t be helpful?)

I’m trying to render text on a SpriteBatch into a UI element (is this the correct way to do it? I already know how to do it with the TextBlock element, but I want to add colored text, so I’m assuming I need a SpriteBatch, just to avoid the XY problem). I’m already calling the SpriteBatch Begin, DrawString and End methods, but I can’t figure out how to put said SpriteBatch into the world, I don’t know which type of UI Element I need or what methods I should call on them. I’ve looked at some of the source code of the demos but I don’t quite see how I’m supposed to do it.

Hello.

Sorry I won’t be able to help you with this one, I’ve switched to another engine quite some time ago
