Script C# untuk Membuat Efek Jejak Kursor di Unity

Di bawah ini adalah skrip yang menghasilkan jejak yang mengikuti kursor mouse di Unity.

• Buat skrip baru, beri nama SC_CursorTrail lalu tempel kode di bawah ini di dalamnya:

SC_CursorTrail.cs

using UnityEngine;

public class SC_CursorTrail : MonoBehaviour
{
    public Color trailColor = new Color(1, 0, 0.38f);
    public float distanceFromCamera = 5;
    public float startWidth = 0.1f;
    public float endWidth = 0f;
    public float trailTime = 0.24f;

    Transform trailTransform;
    Camera thisCamera;

    // Start is called before the first frame update
    void Start()
    {
        thisCamera = GetComponent<Camera>();

        GameObject trailObj = new GameObject("Mouse Trail");
        trailTransform = trailObj.transform;
        TrailRenderer trail = trailObj.AddComponent<TrailRenderer>();
        trail.time = -1f;
        MoveTrailToCursor(Input.mousePosition);
        trail.time = trailTime;
        trail.startWidth = startWidth;
        trail.endWidth = endWidth;
        trail.numCapVertices = 2;
        trail.sharedMaterial = new Material(Shader.Find("Unlit/Color"));
        trail.sharedMaterial.color = trailColor;
    }

    // Update is called once per frame
    void Update()
    {
        MoveTrailToCursor(Input.mousePosition);
    }

    void MoveTrailToCursor(Vector3 screenPosition)
    {
        trailTransform.position = thisCamera.ScreenToWorldPoint(new Vector3(screenPosition.x, screenPosition.y, distanceFromCamera));
    }
}

• Lampirkan SC_CursorTrail ke Kamera Utama

Tekan Putar dan amati jejak yang mengikuti kursor.
