Need help with adding score from 2 different script C#

Questions & Answers

Hi guys! so my first script is when the player pick up an gameobject A, player get 3 points and if the player pick up gameobject B, the player get 5 points.

So as the player keep picking up these objects, the score will keep adding up and this is working fine.

However, I have another script that have gameobject C ( Rocks ) which player have to avoid. if gameobject C collides with a gameobject D (lava), the player get 1 points. (originally, I want the player to get 1 point for avoiding rock, but I find that really difficult to do so i decided to destroy rock and get point instead)

The only problem I am having is that the score does not add both script together as one instead it adds as 2 different score.
so if my player pick up 2 gameobject A, the player get 6 points. and if the gameobject C collides with gameobject D, player get 1 points. so the point should have add up to 7 but it didn’t, the score went back to 1.

here’s the script for the pick up part

public Text scoreText;
public int lettuceValue;
public int wormValue;
private int point;

// Use this for initialization
void Start ()
{
	point = 0;
	SetCountText ();
}

// Update is called once per frame
void Update () 
{
}

void OnTriggerEnter2D(Collider2D other)
{
	if (other.gameObject.CompareTag ("PickUp")) {

		Destroy (other.gameObject);
		point += wormValue;
		SetCountText ();
	} 
	else if (other.gameObject.CompareTag ("PickUp2")) {
		Destroy (other.gameObject);
		point += lettuceValue;
		SetCountText ();
	}
}

void SetCountText ()
{
	scoreText.text = "score:" + point.ToString();
}

}

and this is the avoid script

public Text scoreText;
private int point;

void Start ()
{
	point = 0;
	SetCountText ();
}

void Update ()
{
	

}
// in order for this to work, you must have the collider2D isTrigger AND one of the gameObject MUST have a rigidbody2D
void OnTriggerEnter2D(Collider2D other)
{
	if (other.gameObject.CompareTag ("Load"))
	{

		Destroy (other.gameObject);
		point = point + 1;
		SetCountText ();
	}
}

void SetCountText ()
{
	scoreText.text = "score: " + point.ToString ();
}

}

So how do I get those 2 script scores add everything up as one?

Create a third gameobject and attach this script to it;

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class PointsManager : MonoBehaviour {

    public Text scoreText;

    private int Points;

    public void Start()
    {
        Points = 0;
        scoreText.text = "score:" + Points;
    }

    public void AddPoints(int amount)
    {
        Points = Points + amount;
        scoreText.text = "score:" + Points;
    }
}

Then, modify your first script to look like this;

public int lettuceValue;
public int wormValue;
public PointsManager manager;

void OnTriggerEnter2D(Collider2D other)
{
    if (other.gameObject.CompareTag("PickUp"))
    {
        Destroy(other.gameObject);
        manager.AddPoints(wormValue);
    }
    else if (other.gameObject.CompareTag("PickUp2"))
    {
        Destroy(other.gameObject);
        manager.AddPoints(lettuceValue);
    }
}

And your second script to look like this;

public PointsManager manager;
// in order for this to work, you must have the collider2D isTrigger AND one of the gameObject MUST have a rigidbody2D
void OnTriggerEnter2D(Collider2D other)
{
    if (other.gameObject.CompareTag("Load"))
    {
        Destroy(other.gameObject);
        manager.AddPoints(1);
    }
}

Then just pass the first empty gameobject as an argument to both of your other scripts. The point total should keep a rolling count from both of them.

Make your points public static instead of private. When they are private it means there can be multiple instances of them.

    public void Start()
    {
        Points = 0;
        scoreText.text = "score:" + Points;
    }

    public void AddPoints(int amount)
    {
        Points = Points + amount;
        scoreText.text = "score:" + Points;
    }
}

Then, modify your first script to look like this;

public int lettuceValue;
public int wormValue;
public PointsManager manager;

void OnTriggerEnter2D(Collider2D other)
{
    if (other.gameObject.CompareTag("PickUp"))
    {
        Destroy(other.gameObject);
        manager.AddPoints(wormValue);
    }
    else if (other.gameObject.CompareTag("PickUp2"))
    {
        Destroy(other.gameObject);
        manager.AddPoints(lettuceValue);
    }
}

And your second script to look like this;

public PointsManager manager;
// in order for this to work, you must have the collider2D isTrigger AND one of the gameObject MUST have a rigidbody2D
void OnTriggerEnter2D(Collider2D other)
{
    if (other.gameObject.CompareTag("Load"))
    {
        Destroy(other.gameObject);
        manager.AddPoints(1);
    }
}

Then just pass the first empty gameobject as an argument to both of your scripts.

Sorry if I misunderstand BUT wouldn’t you do this?
put this in avoid script

public PickUpScript pickupscript;

and put this in pick up script

public AvoidScript avoidscript;

and say

     if(//player picks up thingy) 
     {
         avoidscript.scoreint = avoidscript.scoreint + 1;
     }
