查找播放器和相机之间的所有对象 [英] Find all objects between player and camera

问题描述

我正在使用相机的正投影来跟随玩家.我想在玩家和相机之间找到所有游戏对象，以便可以更改不透明度，以便在遮挡相机视图时它们是部分透明的.我读过有关光线投射的信息，但似乎只能在播放器和相机之间提供第一个对象.有什么方法可以做到这一点?

I am using an orthographic projection for camera to follow a player. I would like to find all gameobjects between the player and the camera so I can change the opacity so they are partially transparent while blocking the camera's view. I read about raycasting, but it seems it would give only the first object between the player and camera. What approaches are there to accomplish this?

推荐答案

只需使用物理. RaycastAll 像这样:

public class CameraScript : MonoBehaviour
{
    //Attach this script to the camera//

    public GameObject player;

    void Update()
    {
        float dist = Vector3.Distance(transform.Position, player.transform.position);
        RaycastHit[] hits = hits = Physics.RaycastAll(transform.position, 
                                                      transform.forward, 100.0F);
        foreach (RaycastHit h in hits)
        {
            //Change the opacity of the of each object to semitransparent.
        }
    }
}
