没有重载方法需要 0 个参数

Question

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CollisionDetection : MonoBehaviour {
    public Collision c;
    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {
        OnCollisionEnter ();
    }

    void OnCollisionEnter(Collision c){     
        if (c.gameObject.name == "Wall") {
            Movement.MoveDirection = Vector2.zero;
        }
    }
} 

I can pass the parameter Collision c but i cant pass it back as an argument, when I do I get the error expected 3 with a bunch of syntax on my screen such as: Expected ) , Expected ;

Answer 1

Your method signature doesn't match the invocation. In detail:

void OnCollisionEnter(Collision c) {
    ...
}

Does not match the usage just above where you're invoking it (in Update ):

OnCollisionEnter ();

Answer 2

Remove two lines Public coliision c Oncollision enter()

Everything fine
