以下例子表现了在UNIT3D场景中，动态更改界面字体大小、颜色。

void OnGUI()

{

GUIStyle bb=new GUIStyle();

bb.normal.background = null; 
bb.normal.textColor=new Color(1,0,0);
bb.fontSize = 15; 
offset += 40;
s = "WISEGLOVE数据手套标定方法：按下R建，再完成手册指示的标定手势，完成标定 ";// + facesouth.z.ToString ("F1");
s = GUI.TextField(new Rect(10, offset, 200, 20 + offset), s,bb);
offset += 40;
s = "WISEXMA动捕传感器标定方法：首先转动身体面对屏幕按下A建，再转动身体，\n 下方显示的朝向值接近0时，站直做标准T-POSE,按下C键，完成标定 ";
s = GUI.TextField(new Rect(10, offset, 150, 20 + offset), s,bb);
offset += 80;
s = "朝向:" + facesouth.z.ToString ("F1");
bb.fontSize = 25; 

s = GUI.TextField(new Rect(100, offset, 200, 20 + offset), s,bb);

}
