将旧的Unity代码升级到Unity 5 [英] Upgrading old Unity code to Unity 5

问题描述

在触发按钮上播放动画的代码似乎不起作用.我在Youtube上观看了一个视频，并使用一个简单的animation.Play();对该视频进行了处理，但我无法在我的计算机上使用它.我做错了什么或团结改变了它?请帮助我在网上找不到解决方案.所有解决方案也不起作用".

The code to play animation on trigger button does not seem to work. I saw a video on Youtube and with a simple animation.Play(); it worked on that video but yet, I couldn't get it to work on my computer. What did I do wrong or did unity change it? please help I cant find solution on the net. All the "solution not working either".

这是我得到的错误:

类型UnityEngine.Component不包含播放的定义 而且类型UnityEngine.component的扩展方法Play都不能 被发现

Type UnityEngine.Component does not contain a definition for play and no extension method Play of type UnityEngine.component could be found

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

public class animationtrigger : MonoBehaviour {


    void Start()
    {

    }
    int speed = 10;
    // Update is called once per frame
    void Update () {
        if (Input.GetKeyDown("N"))
        {
            animation.Play("Cube|moving side");
            //transform.Translate(1 * Vector3.forward * Time.deltaTime * speed);
            //Animator anim = GetComponent<Animator>();
            //if (null != anim)
        //  {
        //      anim.Play("Cube|moving side");
        //  }
        }
    }
}

推荐答案

我做错了什么还是团结改变了它?

what did i do wrong or did unity change it?

团结一致.我已经看到相似过去几周的问题.尽管我不认为它们是重复的，但在这里为以后的问题回答所有这些都是很有意义的.

Unity changed. I've seen similar questions for the past few weeks. Although I don't think they are duplicates but it would make sense to answer all these here for future questions.

animation 变量在Component下定义为MonoBehaviour继承的public变量.然后，您的代码将从MonoBehaviour继承，您可以访问animation.

The animation variable is defined under Component as a public variable which MonoBehaviour inherits from. Your code then inherits from MonoBehaviour and you have access to animation.

这些是Component类中不推荐使用的变量的完整列表:

These are the complete list of variables from the Component class that are deprecated:

public Component animation { get; }
public Component audio { get; }
public Component camera { get; }
public Component collider { get; }
public Component collider2D { get; }
public Component constantForce { get; }
public Component guiElement { get; }
public Component guiText { get; }
public Component guiTexture { get; }
public Component hingeJoint { get; }
public Component light { get; }
public Component networkView { get; }
public Component particleEmitter { get; 
public Component particleSystem { get; }
public Component renderer { get; }
public Component rigidbody { get; }
public Component rigidbody2D { get; }

访问附加到相同脚本的组件的新方法:

使用GetComponent<ComponentName>().大写该变量的 first 字母使其成为组件类.音频的一种例外是 AudioSource而不是音频.

Use GetComponent<ComponentName>(). Capitalize the first letter of that variable to make it its component class. One exception is audio which becomes AudioSource instead of Audio.

1 .animation.Play("Cube|moving side");变为GetComponent<Animation>().Play("Cube|moving side");

2 .rigidbody2D.velocity变为GetComponent<Rigidbody2D>().velocity

3 .rigidbody.velocity变为GetComponent<Rigidbody>().velocity

4 .renderer.material变为GetComponent<Renderer>().material

5 .particleSystem.Play()变为GetComponent<ParticleSystem>().Play()

6 .collider2D.bounds变为GetComponent<Collider2D>().bounds

7 .collider.bounds变为GetComponent<Collider>().bounds

8 .audio.Play("shoot");变为GetComponent<AudioSource>().Play("shoot");

9 .camera.depth变为GetComponent<Camera>().depth

我不必将所有内容都放进去，因为下面的示例应指导任何人这样做.这些是SO上最常问到的问题.

I don't have to put all of them because the example below should guide anyone do this. These are the most asked and asked components on SO.

缓存组件:

您可以缓存组件，这样就不必每次都拥有GetComponent.

You can cache component so that you don't have be GetComponent everytime.

Animation myAnimation;
void Start()
{
    //Cache animation component
    myAnimation = GetComponent<Animation>();
}

void Update()
{
    if(somethingHappens)
    {
        //No GetComponent call required again
        myAnimation.Play("Cube|moving side");
    }
}
