MotionBuilder Python Script06 - UI_BoxLayout

fly!

今天再来介绍一下Motionbuilder里面的Box布局

一、BoxLayout

这里主要是关于搭建出Box之后，里面的布局设置，与Script05 BoxCustomParams的并不一样

先来看一下丰满的UI效果

这里凑齐了Box内的所有Layout方法，代码如下：

def CreateTool():
    # Tool creation will serve as the hub for all other controls
    t = FBCreateUniqueTool("Box Example")
    PopulateLayout(t)
    t.StartSizeX = 800
    t.StartSizeY = 800
    ShowTool(t)


CreateTool()

代码脉络清晰，decomposition and refactor!
