在 C# Unity3D 中创建游戏并且它不起作用

Question

my snippets doesn't work in vscode, i use Unity 3.5 and VScode lastest version and public class not show in gameobject there is my code:

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

public class kontrol : MonoBehaviour
{
    public float berat, tinggiLoncat;
    public private void OnParticleCollision(GameObject bird) {
    };
    // Start is called before the first frame update
    void Start()
    {
        
    }

    void OnMouseDown() {
        bird.GetComponent<Rigidbody2D> ().gravityScale = berat;
        bird;GetComponent<Rigidbody2D> ().velocity = new Vector2 ( bird;GetComponent<Rigidbody2D>().velocity.x, tinggiLoncat);
    }

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

}

Answer 1

This isnt working because you have many syntax errors and the script isn't compiling so you cant add it obviously.

    public private void OnParticleCollision(GameObject bird) { // Public Private? Choose one!
    }; //no semicolon after methods
        
        bird.GetComponent<Rigidbody2D> ().gravityScale
        bird;GetComponent<Rigidbody2D> ().velocity //why are you using a semicolon, you did it right in the first place.

1. GetComponent is expensive. Use it once in Awake or Start , and save the reference. For example:

class SomeComponent: MonoBehaviour {
    Rigidbody rb;
    void Awake() {
        rb = GetComponent<Rigidbody>();
    }
    void Update() {
        // do something with rb
    }
}

2. You're using semicolons instead of periods.
