Ngui clip Animation

Environment:

Unity 4.5,NGUI3.5,iTween

Preparation:

Create a uipanel, create another uisprite under uipanel, select softclip for uipanel, and then bind panelcontroller. CS to the Panel, similar

Maskmanager

Bind panelcontroller. CS to uiroot and targets the four panels created above. Click play and press number keys 0, 1, 2, 3, and 4 to switch the effect.
