How can I save the gold in my game scene to the main menu scene?
Hello I have a problem about PlayerPrefs. The golds in the game scene come to the main menu scene, but the previous golds are also deleted. For example; I won 5 gold from the first game, 5 gold will be written on the main menu scene. Let's say I won 4 gold in the second game, normally a total of 9 gold should be written on the main menu scene, but instead of deleting the previous gold, the gold I earned in the last game is written. So 4 will be written. How can I solve this problem? I need your help. I want all the gold to be collected in the main menu scene.
My game scene:
public class PlayerControl : MonoBehaviour
{
private float gold;
public Text goldText;
private void OnCollisionStay(Collision collision)
{
if (collision.gameObject.tag == "Gold")
{
goldText.text=((int)gold).ToString();
gold ++;
PlayerPrefs.SetFloat("Gold", gold);
PlayerPrefs.Save();
Destroy(collision.gameObject);
}
}
}
My main menu scene:
public class Menu : MonoBehaviour
{
public Text goldText;
public float gold;
void Start()
{
PlayerPrefs.SetFloat("Gold",PlayerPrefs.GetFloat("Gold") + gold);
gold=PlayerPrefs.GetFloat("Gold",gold);
goldText.text="Gold: " + gold;
}
Well obviously you already write to the same player pref so you always overwrite previous values.
Unless you really want to save the gold count ever over a game restart i'd suggest you just use a static variable to keep track of your gold. Static variables will be kept over scene changes.
for example:
public class GoldManager
{
public static int PlayerGoldCount = 0;
}
Then you can always just access and change the gold count with GoldManager.PlayerGoldCount ...
If you want to stick with your solution with the playerprefs you have to get the player gold count and add the newly gotten gold count to the last count and then save it again to the player prefs.
