Unity 5.6 2D-如何检查2个对撞机是否没有碰到任何其他对撞机？

问题描述

在Unity 5.6 C＃中，我知道有一种方法可以通过使用IsTouching来检查碰撞器是否被任何其他碰撞器碰触。

In Unity 5.6 C#, I know there is a way to check for if a collider is being touched by any other collider by using IsTouching.

但是，我会想知道如何将两个碰撞器组合在一起（彼此接触），以及如何检查两个碰撞器是否彼此接触。

However, I would like to know how to group two colliders together(that are touching each other), and how to check if they both are touching any collider besides each other.

推荐答案

我会用我在评论中提到的想法试一下（我发现仅凭评论部分很难理解）。

I will give it a shot with the idea I mentioned in the comments (I see it is hard to understand with only the comments section).

我将使用碰撞列表并在此处存储所有触摸，并使用和。

I would use a list of collisions and store any touches here, filtering out the "partner" collider using OnCollisionEnter and OnCollisionExit.

由于两个都附加到同一个GameObject上，因此很容易过滤它们：

Since both are attached to the same GameObject it is easy to filter them:

public class Collisions : MonoBehaviour
{
    // Show in the Inspector for debug
    [SerializeField] private List<Collider> colliderList = new List<Collider>();

    public bool IsTouching => colliderList.Count != 0;

    private void Awake ()
    {
        // Make sure list is empty at start
        colliderList.Clear();
    }

    private void OnCollisionEnter(Collision collision)
    {
        // Filter out own collider
        if(collision.gameObject == gameObject) return;

        if(!colliderList.Contains(collision.collider) colliderList.Add(collision.collider);
    }

    private void OnCollisionExit(Collision collision)
    {
        // Filter out own collider
        if(collision.gameObject == gameObject) return;

        if(colliderList.Contains(collision.collider) colliderList.Remove(collision.collider);
    }
}
