Change UITexutre's material offset at runtime didn't work like it in 2.x

[simon129]

I'm using 3.0.2

reproduce step:

• Create a new scene.
• Through menu [NGUI] -> [Create] -> [Texture]
• Assign "Fantasy Atlas" material provided from NGUI package to UITexture's material
• Attach the code below
• Hit Play

In my game, I use a custom shader to mask the texture, so I can't use UITexture's UV setting.
I tried MarkAsChanged(), it didn't work.
Disable/Enable UITexture or panel.Refresh() work, but I think I should not do that at runtime.
How do I make it work in 3.0.2 ?

Thanks.

1. using UnityEngine;
2. public class UITextureOffset : MonoBehaviour
3. {
4.         float offset;
5.         UITexture tex;
6.         void Start()
7.         {
8.                 tex = GetComponent<UITexture>();
9.         }
10.         void Update()
11.         {
12.                 offset += Time.deltaTime;
13.                 if (offset > 1)
14.                         offset = 0;
15.                 tex.material.mainTextureOffset = new Vector2(offset, 0);
16.         }
17. }
18.

UIWidget.drawCall.dynamicMaterial lets you modify it as you see fit.

Note that this may not be present in 3.0.2 -- but it's there in the current latest version that's available to Pro users -- so if you don't see it, you will see it in the next update.

I've also posted the source code for it a few days ago. It's a simple 'get' property that returns the "mMat" on the draw call.
