Unity3D技术之使用摄像机制作实时显示小地图

1、Unity3d中使用摄像机制作实时显示小地图Unity3d中使用摄像机制作实时显示小地图,以之前的tank为例。开始制作之前场景中物体如图。IIPerspuRGB.:豫n旳Gizmos-&eneTejrtured3CenterLocal开始制作，步骤1新建一个camera及一个plane。对齐位置，将camera改名为camera_UI。旋转plane,使之在camera_UI中显示为竖直状态。效果如下图：亡HisrdrcinyUnilytesi.unirlyPC.Mac&LinuxStaridatonrfileditAssfIsGarncObjecfTerrainMjndowHelpCjm&
