Entry 7: Tiling the Stages

When it comes to endless running, tiling mechanism is pretty crucial

This video show how tiling in Unity3D is made.



So what it does is it spawns the prefab randomly on the z-axis.
By following the tutorial, I'm able to get the tiling function to work.

Here's the code:




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

public class tileManager : MonoBehaviour {

    public GameObject[] tilePrefabs;

    private Transform playerTransform;
    public float spawnZ = -1000.0f;
    public float tileLength = 1900.0f;
    public int amnTilesOnScreen = 3;
    public float safeZone = 1000.0f;
    private int lastPrefabIndex = 0;

    public List<GameObject> activeTiles;

// Use this for initialization
void Start () {
        activeTiles = new List<GameObject>();
        playerTransform = GameObject.FindGameObjectWithTag("Player").transform;

        for(int i = 0;i < amnTilesOnScreen; i++)
        {
            if (i < 3)
                SpawnTile(0);
            else
                SpawnTile();
        }


    }

// Update is called once per frame
void Update () {

        if(playerTransform.position.z - safeZone> (spawnZ - amnTilesOnScreen * tileLength))
        {
            SpawnTile();
            DeleteTile();
        }


}

    void SpawnTile(int prefabIndex = -1)
    {
        GameObject go;
        if (prefabIndex == -1)
            go = Instantiate(tilePrefabs[RandomPrefabIndex()] as GameObject);

        else
            go = Instantiate(tilePrefabs[prefabIndex]) as GameObject;

        go.transform.SetParent(transform);
        go.transform.position = Vector3.forward * spawnZ;
        spawnZ += tileLength;

        activeTiles.Add(go);
    }

    void DeleteTile()
    {
        Destroy(activeTiles[0]);
        activeTiles.RemoveAt(0);
    }

    private int RandomPrefabIndex()
    {
        if (tilePrefabs.Length <= 1)
            return 0;

        int randomIndex = lastPrefabIndex;
        while(randomIndex == lastPrefabIndex)
        {
            randomIndex = Random.Range(0, tilePrefabs.Length);

        }

        lastPrefabIndex = randomIndex;
        return randomIndex;
    }

}

Then I've created a gameObject that stores the code. Then from there, I can start creating some obstacle courses and make it into prefabs.

All I need to do now is to adjust where the prefabs going to spawn so that the coming prefab wouldn't clip with other prefab
