Collision and direction in Unity C#…?

Question

I'm using this code to move to right direction:

transform.Translate(1,0,0);

Then I'm using this to move to opposite direction, I need to change x axis positive/negative.

void OnCollisionEnter2D(Collision2D col){

}

Help me to make it happen.... Thanks in advance.

Answer 1

This Is for newbie like me, it's work for me!

using UnityEngine;
using System.Collections;

public class CollisionAndtheMovement : MonoBehaviour {
    public float speed;
    public bool  toRight;`enter code here`
    // Use this for initialization
    void Start () {
        toRight = true;


    }

    // Update is called once per frame
    void Update (){
        if (toRight) {
            transform.Translate (Vector2.right*Time.deltaTime*speed, 0);
        }

        if (!toRight) {
            transform.Translate (Vector2.left*Time.deltaTime*speed, 0);
        }

    }

    void OnCollisionEnter2D(Collision2D col){
        if (col.gameObject.tag == "Crate" && toRight) {
            toRight = false;
        } else {
            toRight = true;
        }
    }
}

Answer 2

您可以将transform.Right用于此目的，也可以用于相反方向-transform.Right可以解决问题。

Answer 3

To go the opposite direction, just make the number negative.

void OnCollisionEnter2D(Collision2D col){
  transform.Translate(-1,0,0);
}
