Minimap plug-in

One 、 First, we import the plug-in package Minimap.unitypackage

1、 Drag the mini map preset to the scene

2、 There will be two mistakes on the right

3、 On the top Layer Choose from Add Layer： 

4、 In the presence of Layer Add a window named “mapsystem” Of Layer, The name must be “mapsystem”

This is one less error report

5、 The second error is that the target cannot be empty , So drag players here

6、 This mark can be entrusted to the player or NPC The following is a sub object

 

 

 

Two 、 Their own use NGUI Make a small map

1、 Import resources

2、 We add a camera to the scene called minimapCamera, Put the above Audio Listener Remove the components , Adjust the camera position , Place it directly above the character ,X rotate 90 degree , Pictured

The camera can be replaced with rectangular port or conical port

 

 3、 Create a new render map Render Texture We call it minimapTexture,Texture The size there is adjusted to 512*512 Of , As minimapCamera Of Target Texture

 

4、 Choose Mini The camera , Put the rendering map on

 

 5、 Create a shader material,Assets->Create->Material

 6、 Then in the shader Shader Find the one you built there shader, stay Transparent below . At this time, the interface will appear Base（RGB） and Culling Mask,Base（RGB） Drag your previous rendering map up ,Culling Mask Drag the white round picture up , Here's the picture ：

 

 

7、 Use... In the upper right corner of the interface NGUI Map building （ First create a picture and put it in the upper right corner ）

 

8、 Build another one Texture Used to receive the previous material display map

 9、 Drag the previously made materials and maps here

 10、 Create two buttons to zoom in and out

11、 to minimap Add a script Minimap, Add the relevant functions of event control small map to the two keys

  public class Minimap : MonoBehaviour

  {

      private Camera minimapCamera;

      private Transform player;

      private Vector3 offsetPosition;

     void Start ()

     {

         minimapCamera = GameObject.FindGameObjectWithTag(Tags.MINIMAP_CAMERA)

             .GetComponent<Camera>()

         player = GameObject.FindGameObjectWithTag(Tags.PLAYER).transform;

         offsetPosition = minimapCamera.transform.position - player.position;

    }

     void Update()

     {

         minimapCamera.transform.position = offsetPosition + player.position;

     }

     public void ZoomInButtonClick()

     {

         minimapCamera.fieldOfView += 10;

     }

     public void ZoomOutButtonClick()

     {

        minimapCamera.fieldOfView -= 10;

     }

 }

By changing minimapCamera Of fieldOfView To control the zoom of the field of view of the small map , The camera follows the character by setting the distance from the character to remain unchanged

12、 In a small map, like some Npc It is usually displayed as an icon , How to achieve this requirement ？

We can do it in npc Or create a new one above the player model Quad, And give the corresponding icon map , And then all Npc Create a layer NPC, All icons create a layer NpcIcon, Render on the main camera NPC layer , Render on the mini map camera NpcIcon Layer can be  

 

At this time, there will be a problem , Marks can also be seen in the scene , At this time, you just need to click the main camera and choose to remove the mask NPC And the player's tag layer is not selected
