Procedurally generate a TextMesh
I am trying to display 3d text in the world and TextMesh seems to be the way to go. Here is what I have so far:
var wallTxt = new GameObject("WallText");
wallTxt.AddComponent(TextMesh);
wallTxt.AddComponent(MeshRenderer);
wallTxt.GetComponent (TextMesh).text = "Hello World";
var myFont : Font = (Resources.Load("Courier") as Font);
wallTxt.GetComponent(TextMesh).font = myFont;
wallTxt.transform.position.y = 10;
GameObject.CreatePrimitive(PrimitiveType.Cube).transform.position.y = 10;
It displays something but the text is all black blocks instead of letters. Any ideas how to do this properly?
It's simpler if you create a prefab of a TextMesh, and then instantiate the prefab.
var textMeshPrefab : TextMesh;
function Start () { var wallTxt : TextMesh = Instantiate(textMeshPrefab, Vector3.up*10, Quaternion.identity); wallTxt.text = "Hello World"; }

The answer to this question is to instantiate a Text$$anonymous$$esh from a prefab. But is that the most elegant solution? I ran into the same roadblock when trying to build a Text$$anonymous$$esh dynamically from code. And I'm not finding any other answers.
Is there a reason why a dynamically generated Text$$anonymous$$esh does not have the same default material and font as one that you create in the editor?
You were on the right track. After some futzing I got this to work:
var wallTxt = new GameObject("TextField"); wallTxt.AddComponent(TextMesh); wallTxt.AddComponent(MeshRenderer); var meshRender: MeshRenderer = wallTxt.GetComponent(MeshRenderer); var material: Material = meshRender.material; meshRender.material = Resources.Load("Arial", Material); wallTxt.GetComponent (TextMesh).text = "Hello world"; var myFont : Font = Resources.Load("Arial",Font); wallTxt.GetComponent(TextMesh).font = myFont;
Just be sure to create a Resources folder in the Assets folder and put the font you want to load in there.
Try doing the same procedure in the editor and compare the result of your script with the working textmesh from the editor.
OLD ANSWER. But you need to attach the font material to the Mesh Renderer.
