unity3d的世界坐标转化成屏幕坐标

unity3d的世界坐标转化成屏幕坐标

使用函数：Camera.WorldToScreenPoint

原型：function WorldToScreenPoint (position : Vector3) : Vector3

返回值：Vector3 中 x,y是屏幕中的位置，z是坐标到摄像机的距离 屏幕左下方是(0,0);右上方是(pixelWidth,pixelHeight)

例程：

[java] view plaincopyprint?

var target : Transform;

function Update ()

{

var screenPos = camera.WorldToScreenPoint (target.position);

print ("target is " + screenPos.x + " pixels from the left");

}

var target : Transform;
function Update ()
{
var screenPos = camera.WorldToScreenPoint (target.position);
print ("target is " + screenPos.x + " pixels from the left");
}
