How to make background loop and camera follow spawned gameobjects?
How to make background loop and camera follow gameobjects? And what I mean by that is that camera would always be on the latest gameobject. It feels like it takes lots of memory after couple times repeating spawning process so I will need some way to erase past gameobjects which are out of screen. Im new with C# so any help would be greatly appreciated!
So first of all Im using this script to spawn gameobjects:
[SerializeField]
private GameObject _spawnPrefab;
private List<Vector3> _targets = new List<Vector3>();
private void Start()
{
_targets.Add(_spawnPrefab.transform.position);
}
private void Update()
{
Spawn();
}
private void Spawn()
{
if (Input.GetMouseButtonDown(0))
{
GameObject go = Instantiate(_spawnPrefab, _targets.LastOrDefault() + new Vector3(_spawnPrefab.GetComponent<Renderer>().bounds.size.x, 0f), Quaternion.identity);
_targets.Add(go.transform.position);
}
I would like to make the script to work endlessly now it gives Fatal Error what says: "Size overflow in allocator" after ~14 times repeating the spawning process. In hierarcy it spams that gameobject(Clone)Clone)(Clone)(Clone)(Clone)(Clone).. Like ALOT the only component besides that script is Box Collider 2D. I earlier had Rigidbody 2D aswell but it seems like that script multiplies each time when used those current gameobjects.
To be able to follow an object even after it has moved, you need to store its Transform. So change the type of _targets to List<Transform> and the last line in Spawn() to _targets.Add(go.transform);. Then to get the last transform for your camera to follow I would write the following function:
public Transform GetLastTarget () {
if (_targets.Count > 0) { return _targets[_targets.Count - 1]; }
return null;
}
You can use the transform.position from GetLastTarget() for following with your camera. Make sure you check that GetLastTarget() didn't return null!
Good luck!
Thanks for replying! I will try that when I get back to home.
Harinezumi's solution should work. If you have trouble implementing it, give me your email and we can arrange a Skype and Teamviewer session to help you out.
I'm a bit stuck here.
Your help would be much appreciated. Vilzzzu@gmail.com
