Добрый день. Я рисую линию через LineRenderer и перемещаю объект по точкам этой линии впоследствии.
Есть скрипт DrawManager, который отвечает за создание префаба с линией с компонентом LineRender, есть скрипт Line1, который весит на этом префабе и есть PlayerController который управляет объектом.
Всё работает нормально, но если я создаю клон объекта и пытаюсь от него начать рисовать линию, то всё ломается.
Не пойму, как мне сделать независимые друг от друга эти объекты. Я хочу повесить на сцену 4 объекта, чтобы была возможность рисовать для каждого из них линию и чтобы каждый объект, не обращая внимание на другие линии двигался по своей. Вот код:
DrawManager.cs:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DrawManager : MonoBehaviour
{
private Camera _cam;
[SerializeField] private Line1 _linePrefab;
public const float RESOLUTION = .3f;
private Line1 _currentLine;
void Start()
{
_cam = Camera.main;
}
void Update()
{
Vector2 mousePos = _cam.ScreenToWorldPoint(Input.mousePosition);
if (Input.GetMouseButtonDown(0) && PlayerController.canDraw) _currentLine = Instantiate(_linePrefab, mousePos, Quaternion.identity);
if (Input.GetMouseButton(0) && PlayerController.canDraw) _currentLine.SetPosition(mousePos);
}
}
Line1.cs:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Line1 : MonoBehaviour
{
[SerializeField] private LineRenderer _renderer;
private readonly List<Vector2> _points = new List<Vector2>();
private float _deleteDistance = .5f;
public void SetPosition(Vector2 pos)
{
if (!CanAppend(pos)) return;
_points.Add(pos);
_renderer.positionCount++;
_renderer.SetPosition(_renderer.positionCount - 1, pos);
}
private bool CanAppend(Vector2 pos)
{
if (_renderer.positionCount == 0) return true;
return Vector2.Distance(_renderer.GetPosition(_renderer.positionCount - 1), pos) > DrawManager.RESOLUTION;
}
private void OnDestroy()
{
_points.Clear();
_renderer = new LineRenderer();
}
private void Update()
{
if (PlayerController.isMoving)
{
if (_renderer.positionCount > 0 && Vector2.Distance(_renderer.GetPosition(0), PlayerController.positionGlobal.transform.position) < _deleteDistance)
{
_points.RemoveAt(0);
_renderer.positionCount--;
}
}
if (PlayerController.finalMoving) {
if (_points.Count > 1)
_points.Clear();
}
UpdateLine();
}
private void UpdateLine()
{
_renderer.positionCount = _points.Count;
for (int i = 0; i < _points.Count; i++)
{
_renderer.SetPosition(i, _points[i]);
}
}
}

Простой
