Différentes méthodes de mise en œuvre et effets des objets de notes d'apprentissage Unity suivent le mouvement

Il existe de nombreuses façons d'implémenter le mouvement d'objets dans Unity. Cet article présentera 7 méthodes d'implémentation différentes, vous pouvez vous référer à l'effet vous-même

1. Définir la méthode Position

public Transform targetTansform;

In Update/FixedUpdate:
this.transform.position = targetTansform.position;

2. Méthode Vector3.Lerp()

public Transform targetTansform;
public float lerpSpeed = 5f;
In Update/FixedUpdate:
this.transform.position = Vector3.Lerp(this.transform.position,targetTansform.position, lerpSpeed * Time.fixedDeltaTime);

3. Méthode Vector3.MoveTowards()

public Transform targetTansform;
public float moveSpeed = 5f;
In Update/FixedUpdate:
this.transform.position = Vector3.MoveTowards(this.transform.position,targetTansform.position, moveSpeed * Time.fixedDeltaTime);

4. Vector3.MoveTowards() combiné avec la méthode Vector3.Lerp()

public Transform targetTansform;
public float lerpSpeed = 5f;
public float moveSpeed = 5f;
In Update/FixedUpdate:
this.transform.position = Vector3.MoveTowards(this.transform.position,Vector3.Lerp(this.transform.position,targetTansform.position, lerpSpeed * Time.fixedDeltaTime), moveSpeed * Time.fixedDeltaTime);

5. Méthode Vector3.SmoothDamp()

public Transform targetTansform;
public float dampSpeed = 100f;
In Update/FixedUpdate:
this.transform.position = Vector3.SmoothDamp(this.transform.position,targetTansform.position, ref velocity,dampSpeed * Time.fixedDeltaTime);

6. Méthode AddForce()

public Transform targetTansform;
private Vector3 velocity = Vector3.zero;
In Update/FixedUpdate:
Vector3 force = targetTansform.position - transform.position;
force = force.normalized;
force = force * forceSpeed;
this.transform.GetComponent<Rigidbody>().AddForce(force);

7. méthode transform.Translate ()

public Transform targetTansform;
In Update/FixedUpdate:
Vector3 moveDirection = targetTansform.position - transform.position;
transform.Translate(moveDirection,Space.World);

                this.transform.position = Vector3.MoveTowards(this.transform.position,targetTansform.position, moveSpeed * Time.fixedDeltaTime);

            case FollowType.MoveTowardsAndLerp:

                break;
            case FollowType.SmoothDamp:
                this.transform.position = Vector3.SmoothDamp(this.transform.position,targetTansform.position, ref velocity,dampSpeed * Time.fixedDeltaTime);
                break;
            case FollowType.RigibodyAddForce:
                Vector3 force = targetTansform.position - transform.position;
                force = force.normalized;
                force = force * forceSpeed;
                transform.GetComponent<Rigidbody>().AddForce(force);
                break;
            case FollowType.Translate:
                Vector3 moveDirection = targetTansform.position - transform.position;
                transform.Translate(moveDirection,Space.World);
                break;
            
        }
