Skyline을 생성하는 방법

using UnityEngine;

public class SkylineManager : MonoBehaviour {

	public Transform prefab;
}

	public Transform prefab;
	public int numberOfObjects;
	public Vector3 startPosition;

	private Vector3 nextPosition;

	void Start () {
		nextPosition = startPosition;
	}

	void Start () {
		nextPosition = startPosition;
		for (int i = 0; i < numberOfObjects; i++) {
			Transform o = (Transform)Instantiate(prefab);
			o.localPosition = nextPosition;
			nextPosition.x += o.localScale.x;
		}
	}

 

using UnityEngine;

public class Runner : MonoBehaviour {

	public static float distanceTraveled;

	void Update () {
		transform.Translate(5f * Time.deltaTime, 0f, 0f);
		distanceTraveled = transform.localPosition.x;
	}
}

큐란 무엇일까요?(자료구조) 바로가기

using UnityEngine;
using System.Collections.Generic;
