GameObject的领导者/C问题 [英] GameObject's Following a Leader / Centipede Issue

问题描述

我很难将一些GameObject链接在一起以跟随领导者".

I am having difficulty chaining together some GameObjects to "Follow the leader".

这是我要完成的工作:

有头"对象的地方，它随它一起拉body对象.像蛇或cent.

Where there is a "head" object and it pulls the body objects with it. Like a snake or centipede.

但是，这是正在发生的事情

However, this is what is happening:

它们都跟着头部走，但是它们似乎整体上都在运动.

They all kinda follow the head and but they seem to move as a whole.

有人可以看到我在做什么错吗?

Can anyone see what I am doing wrong?

这是其他类继承的my对象. 我开始尝试只让CentipedeObject移动所有独立GameObjects的想法.但这是行不通的.

Here is my Centipede Object that the others classes inherit from. I started to tinker with the idea of just making the CentipedeObject move all of the independent GameObjects. But that didn't work.

CentipedeObject.cs

public abstract class CentipedeObject : MonoBehaviour {

    [SerializeField]
    private float moveSpeed = 1.5f;

    public float MoveSpeed {
        get {
            return moveSpeed;
        }
    }
}

这是进行移动的 CentipedeHead .

public class CentipedeHead : CentipedeObject {

    private Rigidbody2D _body;
    private Vector2 moveDirection = Vector2.zero;
    private void Awake() {
        _body = GetComponent<Rigidbody2D>();
        _body.gravityScale = 0;
        _body.constraints = RigidbodyConstraints2D.FreezeRotation;

    }
    private void Start() {
        InvokeRepeating("ChangeDirection", 0, Random.Range(1.25f, 3.0f));
    }

    private void FixedUpdate() {
        _body.velocity = moveDirection.normalized * MoveSpeed;
    }

    private void ChangeDirection() {

        moveDirection = Vector2.zero;

        switch (Random.Range(0, 4)) {
            case 0:
                moveDirection += Vector2.up;
                break;
            case 1:
                moveDirection += Vector2.right;
                break;
            case 2:
                moveDirection += Vector2.down;
                break;
            case 3:
                moveDirection += Vector2.left;
                break;

        }
    }
}

C身体部分应该紧跟头部或其他身体部分.

And the CentipedeBody part that should just follow the head or another body part.

public class CentipedeBody : CentipedeObject {

    public GameObject objectToFollow;

    private Vector3 followSize;

    void Start() {
        //Get the size of the object we are following
        followSize = objectToFollow.GetComponent<SpriteRenderer>().bounds.size;

        //Set initial distance
        transform.position = objectToFollow.transform.position + followSize;
    }

    private void FixedUpdate() {
        Vector3 followFromPosition = objectToFollow.transform.position + followSize;
        transform.position = Vector3.MoveTowards(transform.position, followFromPosition, MoveSpeed * Time.deltaTime);
    }
}

推荐答案

我认为更新像素的逻辑是错误的.当头部向左移动一个像素时.您正在使所有其他身体部位向左移动1个像素.您所需要做的是(从图中)2确切地位于1所在的位置. 3取代了2，以此类推.

I think the logic of updating the pixels is wrong. When the head moves one pixel left. You are making all other body parts move left by 1 pixel. Where as what you need to do is that (from your diagram) 2 takes the exact place where 1 was. 3 takes the place where 2 was and so on.
