公式ユニティ トレーニングhttps://www.youtube.com/watch?v=D5MqLcO6A8g を見つけて、バグを見つけました (スコアを見てください)。

私はそれを修正するために約2日を費やし、失敗しました。「DontGoThroughThings」スクリプトを見つけて、2D で使用できるように書き直そうとしました。また失敗)

私を助けてください！

これは書き換えスクリプトです：

public LayerMask layerMask; //make sure we aren't in this layer 
public float skinWidth; //probably doesn't need to be changed 

private float minimumExtent; 
private float partialExtent; 
private float sqrMinimumExtent; 
private Vector2 previousPosition; 
private Rigidbody2D myRigidbody; 


//initialize values 
void Awake() 
{ 
    myRigidbody = GetComponent<Rigidbody2D>(); 
    previousPosition = myRigidbody.position;
    minimumExtent = Mathf.Min(Mathf.Min(GetComponent<Collider2D>().bounds.extents.x, GetComponent<Collider2D>().bounds.extents.y)); 
    partialExtent = minimumExtent * (1.0f - skinWidth); 
    sqrMinimumExtent = minimumExtent * minimumExtent; 
} 

void FixedUpdate() 
{ 
    //have we moved more than our minimum extent? 
    Vector2 movementThisStep = myRigidbody.position - previousPosition; 
    float movementSqrMagnitude = movementThisStep.sqrMagnitude;

    if (movementSqrMagnitude > sqrMinimumExtent) 
    { 
        float movementMagnitude = Mathf.Sqrt(movementSqrMagnitude);
        //RaycastHit2D hitInfo; 

        //check for obstructions we might have missed 
        if (Physics2D.Raycast(previousPosition, movementThisStep, movementMagnitude, 0, layerMask.value)) 
            myRigidbody.position = (movementThisStep/movementMagnitude)*partialExtent;
        Debug.DrawLine(myRigidbody.position, myRigidbody.position - previousPosition, Color.green);
    } 

    previousPosition = myRigidbody.position; 
}

これはユニティパッケージですhttps://www.dropbox.com/s/a3n1dalbc1k0k42/Hat%20Trick.unitypackage?dl=0

PS私の英語で申し訳ありませんが、助けてくれてありがとう!!

これは、このスクリプトを書き直した 2D バージョンです (Unity 4.6 用):

using UnityEngine;
using System.Collections;

public class DontGoThroughThings : MonoBehaviour
{
    public delegate void CollidedDelegate(Collider2D collider);
    public event CollidedDelegate Collided;

    public LayerMask layerMask; //make sure we aren't in this layer 
    public float skinWidth = 0.1f; //probably doesn't need to be changed 

    private float minimumExtent;
    private float partialExtent;
    private float sqrMinimumExtent;
    private Vector2 previousPosition;
    private Rigidbody2D myRigidbody;



    //initialize values 
    void Awake()
    {
        myRigidbody = rigidbody2D;
        previousPosition = myRigidbody.transform.position;
        minimumExtent = Mathf.Min(BoundsOf(collider2D).extents.x, BoundsOf(collider2D).extents.y);
        partialExtent = minimumExtent * (1.0f - skinWidth);
        sqrMinimumExtent = minimumExtent * minimumExtent;
    }

    void FixedUpdate()
    {
        //have we moved more than our minimum extent? 
        Vector2 movementThisStep = (Vector2)myRigidbody.transform.position - previousPosition;
        float movementSqrMagnitude = movementThisStep.sqrMagnitude;

        if (movementSqrMagnitude > sqrMinimumExtent)
        {
            float movementMagnitude = Mathf.Sqrt(movementSqrMagnitude);

            //check for obstructions we might have missed 
            RaycastHit2D[] hitsInfo = Physics2D.RaycastAll(previousPosition, movementThisStep, movementMagnitude, layerMask.value);

            //Going backward because we want to look at the first collisions first. Because we want to destroy the once that are closer to previous position
            for (int i = hitsInfo.Length-1; i >= 0; i--)
            {
                var hitInfo = hitsInfo[i];
                if (hitInfo && hitInfo.rigidbody != rigidbody2D)
                {
                    if (Collided != null)
                    {
                        Collided(hitInfo.collider);
                    }
                }
            }
        }

        previousPosition = myRigidbody.transform.position;
    }

    // compute bounds in local space
    public static Bounds BoundsOf(Collider2D collider) {
        var bounds = new Bounds();

        var bc = collider as BoxCollider2D;
        if (bc) {
            var ext = bc.size * 0.5f;
            bounds.Encapsulate(new Vector3(-ext.x, -ext.y, 0f));
            bounds.Encapsulate(new Vector3(ext.x, ext.y, 0f));
            return bounds;
        }

        var cc = collider as CircleCollider2D;
        if (cc) {
            var r = cc.radius;
            bounds.Encapsulate(new Vector3(-r, -r, 0f));
            bounds.Encapsulate(new Vector3(r, r, 0f));
            return bounds;
        }


        // others :P
        //Debug.LogWarning("Unknown type "+bounds);

        return bounds;
    }

    // return bounds in world space
    public static Bounds BoundsColliders(GameObject obj) {
        var bounds = new Bounds(obj.transform.position, Vector3.zero);

        var colliders = obj.GetComponentsInChildren<Collider2D>();
        foreach(var c in colliders) {
            var blocal = BoundsOf(c);
            var t = c.transform;
            var max = t.TransformPoint(blocal.max);
            bounds.Encapsulate(max);
            var min = t.TransformPoint(blocal.min);
            bounds.Encapsulate(min);
        }

        return bounds;
    }


}

それがあなたのために働くかどうか私に知らせてください。

ありがとう、リダン
