How to use a public int in another script?
Hello,
I have a script, which will display on the menu your total coins.
In my game, I have a score, and when you die, the score must be updated to your coins. Now what I have done, is when you get a point for your score, it also needs to be updated directly to the total coins. So the same OnTriggerEnter2D function.
This is my coins script:
public static Coins C;
public Text coinsText;
public int coins;
// Use this for initialization
void Start () {
C = this;
coinsText.text = " " + coins;
PlayerPrefs.SetInt ("coins",1);
Update();
}
// Update is called once per frame
void Update () {
Score.HS.OnTriggerEnter2D ();
coins = PlayerPrefs.GetInt("coins");
}
And this is my Score script:
public static Score HS;
public Text scoreText;
public Text HighScore;
public int krolschValue;
public int score;
Coins int coins;
int highScore;
void start () {
HS = this;
score = 0;
UpdateScore ();
highScore = PlayerPrefs.GetInt("HighScore1",1);
}
public void OnTriggerEnter2D () {
score += krolschValue;
coins += krolschValue;
UpdateScore ();
}
public void UpdateScore () {
scoreText.text = "X " + score;
HighScore.text = "HighScore: " + highScore;
}
public void CheckHighScore()
{
if(score > highScore)
{
Debug.Log ("Saving Score");
PlayerPrefs.SetInt("HighScore1",score);
}
}
Now I want the public int coins, from the coin script to the score script, so I can set into the OnTriggerEnter2D function that the coins also should get the value from the score on every point you get.
What I have right now doesn't work, I have set Coins int coins, from the coins script.
try making an instance of coin script in the score script.
if you are using c#, it can be done something like this,
public CoinScript _inst;
from _inst, you can access public variables of coin script from score script
drag drop the CoinScript object in the inspector.
Okay, so in the score script, I have set a public Coins (which is name of coinscript) _inst;
And in the void OnTriggerEnter2D, I have set:
coins += krolschValue;
but i doesn't work, it can't get the int coins.
You have to get the object in with coin script is attached.
CoinScript _intstance;
void Start()
{
_instance = GameObjectwithCoinScript.getcomponent<CoinScript>();
}
and now you can access the coins
What do I need to get exactly in the void Start?
$$anonymous$$y GameObject where the Coins script is in, is called Coins$$anonymous$$anager
And the coins script is: Coins
How many scripts do you have ? and which script do you have coins (variable)? You have to get the game object whose variable you want to access.
You need to access the script that is attached to another GameObject, the easiest way to this is the following:
GameObject with your UI Script
public Text coinsText;
public int coins;
GameObject with your Score logic
public Coins UIgameObject;
public int score;
public void OnTriggerEnter2D ()
{
score += krolschValue;
UIgameObject.coins += krolschValue;
UpdateScore ();
}
The "trick" lies inside the Editor, select the the Score Logic GameObject that is inside the Hierarchy window, you will se a field that expects your UI/Coin script, drag the GameObject that has the UI/Coin script to that field, this way the Score Logic will have a pointer to access the script inside the code.
This is Unity 101 I recommend you check the tutorials available in Unity3D.com
