function WorldToScreenPoint (position : Vector3) : Vector3
Description描述
Transforms position from world space into screen space.
从世界空间到屏幕空间变换位置。
Screenspace is defined in pixels. The bottom-left of the screen is (0,0); the right-top is (pixelWidth,pixelHeight). The z position is in world units from the camera.
屏幕空间以像素定义,屏幕左下为0,0,右上是(pixelWidth,pixelHeight),Z的位置是以世界单位衡量的到相机的距离。
