NGUI 3 Support / Re: Multiple widgets on one gameobject possible bug

« on: October 15, 2013, 02:06:47 AM »

It's under menu [NGUI] => [Attach] => [Collider].

Or you can use the hotkey by pressing  [Alt]+[Shift]+[C]

NGUI 3 Support / Change UITexutre's material offset at runtime didn't work like it in 2.x

« on: October 15, 2013, 01:55:27 AM »

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.

Simon129, can you explain to me that works?

I upload a picture, and hope you can understand what I mean.

NGUI 3 Support / Re: Tweening multiple gameobjects with one tween event

Using UITweener.tweenGroup property ?

It can trigger multiple tweens

(3) UIDraggablePanel

The DraggablePanel works by having all the items in the draggable panel present and as you drab the panel they pop in and out of view. By my thinking, if I have 10 or 1000, if only 10 are shown in the window at any one time then surely there is no performance by having 1000? Problem is, deleting objects and creating them on the fly is surely going to bad for garbage collection. My question is basically, if I create 100 objects as my max and even if I am only using about 10 or so at a time on screen, is there a performance hit for having so many in the panel. This is of course in relation to UIDraggablePanel seemingly being quite slow on the iPhone4.

I have a draggable panel with clipping and instantiate about 150 items on it, it's very slow.
I optimize my code with the idea of "object pool", only create 5 items, and shift/un-shift the item to bottom/top of the draggable panel when it's out of visible area.
No more instantiating and destroying at runtime.

NGUI 3 Support / Re: Clip non NGUI objects

« on: August 08, 2012, 04:08:13 AM »

2D clipped shader can't be used in 3D objects.

But, you can use another camera like "Example 8 - Scroll View (Camera)" did.

NGUI 3 Support / Re: UITexture MakePixelPerfect() may need pixelSize

« on: August 06, 2012, 09:15:24 PM »

Everything under UIRoot is pixel-based.

Local scale X/Y = pixel width/pixel height.

Just adjust local scale.

I made my own UITextureUV based on UITexture.

NGUI 3 Support / Re: 123ms UIPanel.LateUpdate!?

« on: August 01, 2012, 01:22:34 AM »

If I have a large UIPanel and have about 50 widgets on it, only 1 of them with a looped color tween and others are static buttons, should I isolate that widget to it's own UIPanel to avoid the whole UIPanel to rebuild the buffer on every update to gain better performance ?

Thanks

NGUI 3 Support / Re: 123ms UIPanel.LateUpdate!?

« on: August 01, 2012, 01:13:38 AM »

That's way excessive. You need to move your animated widgets into their own panel, if possible. Them changing every frame means that the draw buffer used for them must be re-created every frame -- and if they have 44 other widgets under the same panel that means 44 others also get affected.

Are tween color and tween scale also "animated widgets" and cause UIPanel to rebuild the buffer, or just position related tween ?

thanks

NGUI 3 Support / Re: Adding prefabs of UIDragPanelContents is too large when Instantiated to scene

« on: July 11, 2012, 10:23:48 PM »

Everything NGUI should be under UIRoot, and their scale should be based on pixel.

you can box ur sprits with an empty gameobject with local scale (1,1,1), and after u instantiate and parent it to UIRoot/Anchor/UIPanel/,  make sure it's local scale is (1,1,1)

NGUI 3 Support / Re: UIButton's color in DraggablePanel problem

« on: July 11, 2012, 05:50:26 AM »

I have a situation like yours, here is how I do,

I try to mimic how UICamera.ProcessTouch(bool, bool) does on OnDrag and OnClick

1. public UICamera mCam;
2. void OnDrag(Vector2 delta)
3. {
4.     if (UICamera.currentTouch.totalDelta.magnitude > mCam.touchClickThreshold)
5.     {
6.         tween off
7.     }
8. }
