Unity: Add a Text Using a TextMesh Via Script? - unity3d

Question

I just want to be able to see some text rendered in the world.
The only example code that I've found is this:
GameObject Text = new GameObject();
TextMesh textMesh = Text.AddComponent<TextMesh>();
textMesh.font = new Font();
mat.SetColor("_Color", Color.black);
mat.SetPass(0);
meshRenderer.material = mat;
textMesh.text = "Hello World!";
Where mat is defined by the code:
Shader shader = Shader.Find("Hidden/Internal-Colored");
mat = new Material(shader);
mat.hideFlags = HideFlags.HideAndDontSave;
mat.SetInt("_Cull", (int)UnityEngine.Rendering.CullMode.Off);
mat.SetInt("_ZWrite", 0);
mat.SetColor("_Color", Color.blue);
mat.SetPass(0);
This code is added to the Start of MonoBevaviour. And the script is tied to Game Main camera.
No text appears anywhere that I can see.

Ah I think I might have something.
I am not sure though if this works for VR devices - I know that Unity e.g. doesn't render Screenspace overlay canvas on XR.
But back to the point: There is a legacy UI system which is usually not used anymore except for in editor Inspector scripting IMGUI
I think it might actually fit your very special need using GUILayout.Label you should be able to draw a flat label onto the screen even in VR.
With GUI.Label you have full control over the pixel coordinates and size.
public class YourTextDrawer : MonoBehaviour
{
void OnGUI()
{
var color = GUI.color;
GUI.color = Color.green;
var textPosition = new Rect(Screen.width / 2 - 150, Screen.height / 2 - 100, 300, 200);
GUI.Label(textPosition, "Hello World!");
GUI.color = color;
}
}
Not tested, just scrabbling this down from memory right now
And actually thinking about it, this might even work for your image as well
