This article mainly introduces Unity3D how to customize the bulletin board, the article is very detailed, has a certain reference value, interested friends must read it!

Make a bulletin board

Create a Canvas for UI, change the Render Mode mode to World Space, and then drag the Canvas canvas into a folder to become a prefab

Add Image background image, then add Text,Canvas canvas, Text text width and height are all set to 0, and the size of the bulletin board is set by Image

Set the anchor point and other related attributes again.

Finally, bind our control script.

In this way, a custom bulletin board is made.

Mode one

If the lens zoom lens is set to the fieldOfView value of the lens

Using UnityEngine

/ * * customize the bulletin board, follow the lens rotation and always face the screen in parallel, follow the lens to zoom and zoom the same size * / public class Billboard: MonoBehaviour {Camera camera;// main lens

Private float _ fieldOfView;// initial fieldOfView

Void Start () {camera = Camera.main; _ fieldOfView = camera.fieldOfView;} void Update () {/ / follow the rotation of the lens and directly assign the rotation value of the main lens to the bulletin board. Transform.rotation = camera.transform.rotation; / / follow the lens to zoom (zoom the lens is set to the fieldOfView value of the lens) float fieldOfView = camera.fieldOfView Transform.localScale = new Vector3 (fieldOfView/_fieldOfView,fieldOfView/_fieldOfView,fieldOfView/_fieldOfView);}

} Mode two

If the lens zooms the position of the lens set by the lens

Using UnityEngine

/ * * customize the bulletin board, follow the lens rotation and always face the screen in parallel, follow the lens to zoom and zoom the same size * / public class Billboard: MonoBehaviour {Camera camera;// main lens

Private float _ distance;// initial distance

Void Start () {camera = Camera.main; _ distance = Vector3.Distance (camera.transform.position, transform.position);} void Update () {/ / follow the rotation of the lens and directly assign the rotation value of the main lens to the bulletin board to transform.rotation = camera.transform.rotation

/ / follow the lens zoom (zoom the position of the lens set by the lens), float distance = Vector3.Distance (camera.transform.position, transform.position) according to the distance from the bulletin board to the main lens; / / the ever-changing distance var scale = distance/_distance * 0.1F; transform.localScale = new Vector3 (scale,scale,scale);}} effect

The following effect does not follow the zoom. If you want to follow the zoom, you can comment on the zoom part of the script code.
