I’m making a vertically scrolling 2d background that loops.
Here’s the code:
using UnityEngine;
using System.Collections;
public class BackGround : MonoBehaviour {
//the point the background goes back to start
private float reset = 19.2f;
//the point where the background goes after a reset
private float startPoint = -19.2f;
//the speed of movement
private float speed;
void Update () {
//if the background is at reset point, move it to startPoint
if(reset <= transform.position.y) {
transform.position = (new Vector3(0, startPoint, 0));
}
//EnemySpawner.speedPlus is a static float
speed = 0.05f + EnemySpawner.speedPlus;
//Move the backgound up
transform.position += new Vector3(0,speed,0);
}
}
The problem is that there is a space between the backgrounds where is nothing. Background 1 is set to (0,0,0) and background 2 is at (0,-19.2,0). -19.2 seems to be the right coordinate so that the background 2 is just right under the background 1 (they are the same picture).
As you can see in the image, there is a white line between the backgrounds. I want that line gone.
It’s my first post here so pardon me if i did something wrong. Also feel free to ask anything.
It is probably because of the origin of the “reset point”. Try moving the reset point a bit closer than before.
Solution : 2
Instead of moving backgrounds by repositioning, try Instantiating the backgrounds and have a constant scrolling of backgrounds. Destroy panes that go out of camera view to improve performance as well.
Managed to fix it with my own way as changing reset point didn’t help and solution 2 was too time consuming. For anyone with the same problem i just made the background to go to the exact position of the lower backgrounds end.
using UnityEngine;
using System.Collections;
public class BackGround : MonoBehaviour {
//the point the background goes back to start
private float reset = 19.2f;
//the point where the background goes after a reset
private float startPoint;
//the speed of movement
private float speed;
public GameObject otherBackground;
void Update () {
SpriteRenderer sRenderer = otherBackground.GetComponent<SpriteRenderer>();
startPoint = transform.position.y - sRenderer.bounds.size.y*2;
//if the background is at reset point, move it to startPoint
if(reset <= transform.position.y) {
transform.position = (new Vector3(0, startPoint, 0));
}
//EnemySpawner.speedPlus is a static float
speed = 0.05f + EnemySpawner.speedPlus;
//Move the backgound up
transform.position += new Vector3(0,speed,0);
}
}
Thanks for the support anyway.
