How to instantiate and destroy objects with 2d trigger
I am making a 2d game: Car Escape.
I want to make 50 levels in one scene. Levels are prefabs and I need some help with code. How can I make level 1 show initially and if I passed level 1, instantiate level 2 and destroy level 1 with OnTriggerEnter2D, etc.
public class WinZoneScript : MonoBehaviour {
// Reference to WinText game object
public GameObject []levels; //levels map
public GameObject panel; //panel next button to go to next level
public int level; // number of ever levels
//Use this for initialization
void Start ()
{
panel.gameObject.SetActive(false);
level = PlayerPrefs.GetInt("level", level);
levels[level].gameObject.SetActive(enabled);
}
// If target car (red one) exits the playground
void OnTriggerEnter2D (Collider2D col)
{
// then "You Win!" sign is turned on
levels[level].gameObject.SetActive(false);
panel.gameObject.SetActive(enabled);
PlayerPrefs.SetInt("level", level);
}
public void Next()
{
PlayerPrefs.GetInt("level", level);
panel.gameObject.SetActive(false);
PlayerPrefs.Save();
}
Best Answer
You need to instantiate your each level prefabs. So your script should be like:
public GameObject []levels; //levels map
public GameObject panel; //panel next button to go to next level
public int level; // number of ever levels
private GameObject activeLevel;
void Start() {
panel.gameObject.SetActive(false);
level = PlayerPrefs.GetInt("level", level);
activeLevel = Instantiate(levels[level]);
}
// If target car (red one) exits the playground
void OnTriggerEnter2D(Collider2D col) {
// then "You Win!" sign is turned on
//player presses proceed button and Next method is called
}
public void Next() {
Destroy(activeLevel); //unless you want to just deactivate it
if(level < levels.Length - 1){ //get the mext level if available
level++;
PlayerPrefs.SetInt("level", level);
PlayerPrefs.Save();
activeLevel = Instantiate(levels[level]);
}
}
