Graphics

[YstadYakuza]

I'm drawing some debug info using the code from the examples, such as:

GameScene.AdHocDraw += () => 
{
Director.Instance.GL.ModelMatrix.Push();
Director.Instance.GL.ModelMatrix.SetIdentity();//go in world space

Director.Instance.GL.SetBlendMode(BlendMode.Normal);
Director.Instance.SpriteRenderer.DefaultFontShader.SetColor(ref Colors.Yellow);

Director.Instance.SpriteRenderer.DrawTextDebug(
 GetDebugInfo(),
 GameScene.LocalToWorld(new Vector2(100f, 100f)), 
 GameScene.Camera2D.GetPixelSize() * EmbeddedDebugFontData.CharSizei.Y
);

Director.Instance.GL.ModelMatrix.Pop();
};

 The problem that I have is that the debug text is drawn below all other graphics so I can't see it.

I've tried setting the VertexZ on all my sprites but I can't get them lower than than the debug text. Anyone know how to fix this?

Thanks

Hi YstafYakuza,

A simple way that you can get around these ordering issues that you are seeing is to adjust the order of the Node's which are appearing on top of the text. 

scene.AddChild( sprite, -1 );

The -1 will result in the sprite being drawn on the bottom, and hence underneath the debug text. I appreciate that this may not be the best of solutions, but I will enquire as to whether there are any alternative options that you can try. 

Thanks

Thanks for helping.

How is that different from setting Sprite.VertexZ to -1? I would have thought that I was basically doing the same thing already.

Well the VertexZ property would help if you were drawing items into the 3d space (although you'd need to look at the Znear property of the Camera class). The -1 on the AddChild call specifies the draw order of the sprites, so in this example making the sprite be the first drawn (i.e. at the bottom).
