错误 CS7036：没有给出与所需形式参数“播放器”相对应的参数无法找出代码的问题？

Question

我还是编码新手，这个问题让我陷入困境。

我在关注tutorial video，了解如何制作开机脚本，但由于某种原因，它不起作用。

我一直在寻找解决方案，但它们似乎都不起作用。任何帮助将不胜感激！

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

public class PowerUpPickupEffect : MonoBehaviour 
{
    public GameObject pickupEffect;

    public float multiplier = 2.0f;

    void OnTriggerEnter2D (Collider2D other)
    {
        if (other.CompareTag ("Player")) 
        {
            Pickup ();
        }
    }

    void Pickup (Collider player) 
    {
        Instantiate (pickupEffect, transform.position, transform.rotation);

        player.transform.localScale *= multiplier;

        Destroy (gameObject);
    }
}

Answer 1

您的方法PickUp 需要Collider 作为参数。

但是：请注意 Collider != Collider2D
它们来自两个完全独立的物理引擎 Physics 和 Physics2D！

对于 2D 应该是

void OnTriggerEnter2D(Collider2D other)
{
    if (other.CompareTag("Player"))
    {
        // pass in the expected argument
        Pickup(other);
    }
}

void Pickup(Collider2D player)
{
    Instantiate(pickupEffect, transform.position, transform.rotation);

    player.transform.localScale *= multiplier;

    Destroy(gameObject);
}

或用于 3D

void OnTriggerEnter(Collider other)
{
    if (other.CompareTag("Player"))
    {
        // pass in the expected argument
        Pickup(other);
    }
}

void Pickup(Collider player)
{
    Instantiate(pickupEffect, transform.position, transform.rotation);

    player.transform.localScale *= multiplier;

    Destroy(gameObject);
}
