Unity Learning notes – Infinite map
In many simple stand-alone Parkour or racing games , You don't need to build a big map , You can use small map splicing to realize the function of infinite map .
The specific idea is ： The player is somewhere on the map , When we are about to go out of the border , The map creates another one in front of the character for splicing , It seems that the map can never be finished .
unity There are two inside Plane With a cube Make an introduction ：

default Plane The size is 10x10m, Two Plane Under one goal ;
use Cube Replace the player , Along the Z Drag in the direction cube when ,plane Will follow the alternate generation ;

Don't talk much , Code up ：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class AddPlane : MonoBehaviour
{

    const float width = 10f;// Here is the width of the plane
    public Transform player;
    Vector3 initPos;
    void Start()
    {
          initPos = transform.position;
    }

        void Update()
    {
        float totalWidth = width*2f;// * backGroundNum;
        float distZ = player.position.z - initPos.z;// Calculate the distance between the player and the insertion point in real time
        int n = Mathf.RoundToInt(distZ / totalWidth);// Round it up  

        var pos = initPos;   
        pos.z += n * totalWidth;
        transform.position = pos;
    }
}
