public float orthographicSize ;

描述

处于正交模式时,摄像机大小的一半。

The orthographicSize property defines the viewing volume of an orthographic Camera. To edit orthographicSize, you must set the Camera projection to orthographic.

The height of the viewing volume is (orthographicSize * 2). Unity calculates the width of the viewing volume using orthographicSize and the camera's aspect.

Unity ignores orthographicSize if the camera is not orthographic. Use fieldOfView instead.

public class Example : MonoBehaviour { //Assign this Camera in the Inspector public Camera m_OrthographicCamera; //These are the positions and dimensions of the Camera view in the Game view float m_ViewPositionX, m_ViewPositionY, m_ViewWidth, m_ViewHeight;

void Start() { // This sets the Camera view rectangle to be in the bottom corner of the screen m_ViewPositionX = 0; m_ViewPositionY = 0;

// This sets the Camera view rectangle to be smaller so you can compare the orthographic view of this Camera with the perspective view of the Main Camera m_ViewWidth = 0.4f; m_ViewHeight = 0.4f;

// This enables the Camera (the one that is orthographic) m_OrthographicCamera.enabled = true;

// If the Camera exists in the inspector, enable orthographic mode and change the size if (m_OrthographicCamera) { // This enables the orthographic mode m_OrthographicCamera.orthographic = true;

// Set the size of the viewing volume you'd like the orthographic Camera to pick up m_OrthographicCamera.orthographicSize = 5.0f;

// Set the orthographic Camera Viewport size and position m_OrthographicCamera.rect = new Rect(m_ViewPositionX, m_ViewPositionY, m_ViewWidth, m_ViewHeight); } } }
