move background on scoring system

Questions & Answers

I’m doing a top-down-shooter type of football game and I want the field to move “up” once I reach a certain score, and “down” if I go below a certain score. What I have doesn’t work, but I thought it may be a good starting point.

Here’s something I tried to get the field moving using the score:

 void Update()
    {
        MoveupField();
		
		
    }


public void MoveupField()
    {
        //'field moving code'
        if (Player.Score > 99)
        {
            transform.Translate(Vector3.down, Space.World);
            transform.position = new Vector3(transform.position.x, 1f, transform.position.z);
        }
        if (Player.Score > 199)
        {
            transform.position = new Vector3(transform.position.x, 14f, transform.position.z);
        }
        if (Player.Score > 299)
        {
             transform.position = new Vector3(transform.position.x, 27f, transform.position.z);
        }
        if (Player.Score > 399)
        {
            transform.Translate(Vector3.down, Space.World);
        }
        
    }

Forgive me if this is a silly question, but have you checked what Player.Score actually is, via Debug.Log? In the code you’ve posted, if it’s 99 or less, nothing is going to happen.

First, you’re making it way more complicated than it is. Don’t bother with translate or x / z. Just change transform.position.y = 1, 14, 27 or whatever. And you don’t need to do those tests every frame, only during the event “the score just changed”.

Anyway, your code should work already. Use some print() to see if it goes inside your if(). I suspect it doesn’t, maybe Player.Score is wrong, or maybe the Update function isn’t even run, which would mean the script isn’t attached to an activated game object, or isn’t enabled.

Well I’m sure this probably isn’t the most efficient way to do things, but I got the field to work and move like I wanted. Here’s the code:

using UnityEngine;

using System.Collections;

public class Field : MonoBehaviour
{
#region Variables

public GameObject Field1;
public GameObject Field2;
public GameObject Field3;
public GameObject Field4;
public GameObject Field5;

#endregion

#region Properties
#endregion

#region Functions

void Update()
{
    MoveupField();
	
	
}

public void MoveupField()
{
//‘field moving code’

	//starting field
	if (Player.Score < 199)
	{
		Field1.renderer.enabled = true;
		Field2.renderer.enabled = false;
		Field3.renderer.enabled = false;
		Field4.renderer.enabled = false;
		Field5.renderer.enabled = false;
	}
	//20yrd line
    if (Player.Score > 199)
    {
		//transform.Translate(Vector3.down, Space.World);
        //transform.position = new Vector3(transform.position.x, 1f, transform.position.z);
		Field1.renderer.enabled = false;
		Field2.renderer.enabled = true;
		Field3.renderer.enabled = false;
		Field4.renderer.enabled = false;
		Field5.renderer.enabled = false;
    }
	//50yrd line
    if (Player.Score > 399)
    {
        //transform.position = new Vector3(transform.position.x, 14f, transform.position.z);
		Field1.renderer.enabled = false;
		Field2.renderer.enabled = false;
		Field3.renderer.enabled = true;
		Field4.renderer.enabled = false;
		Field5.renderer.enabled = false;
    }
	//opponet 20yrd line
    if (Player.Score > 599)
    {
        //transform.position = new Vector3(transform.position.x, 27f, transform.position.z);
		Field1.renderer.enabled = false;
		Field2.renderer.enabled = false;
		Field3.renderer.enabled = false;
		Field4.renderer.enabled = true;
		Field5.renderer.enabled = false;
    }
	//goal line
    if (Player.Score > 799)
    {
        //transform.Translate(Vector3.down, Space.World);
		Field1.renderer.enabled = false;
		Field2.renderer.enabled = false;
		Field3.renderer.enabled = false;
		Field4.renderer.enabled = false;
		Field5.renderer.enabled = true;
    }
    
}//end move up field
