what did i do wrong or did unity change it?
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.
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.
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; }
New way to access component that attached to the-same script:
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"); becomes GetComponent<Animation>().Play("Cube|moving side");
2.rigidbody2D.velocity becomes GetComponent<Rigidbody2D>().velocity
3.rigidbody.velocity becomes GetComponent<Rigidbody>().velocity
4.renderer.material becomes GetComponent<Renderer>().material
5.particleSystem.Play() becomes GetComponent<ParticleSystem>().Play()
6.collider2D.bounds becomes GetComponent<Collider2D>().bounds
7.collider.bounds becomes GetComponent<Collider>().bounds
8.audio.Play("shoot"); becomes GetComponent<AudioSource>().Play("shoot");
9.camera.depth becomes GetComponent<Camera>().depth
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.
Cache Component:
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");
}
}
