How to play Animator when something happens?

Hi there,

quick description:

I have:
- camera
- about 20 different objects
- destroyed versions of these objects

I want to play an Animator in the camera (very quick zoom in and zoom out) when the object is destroyed. How can I do that?

From what I know, the code should partly look like that:

Code (CSharp):

1.     Animator anim;    
2.  
3. if ( Here's the part, where I don't know what to put )
4.         {
5.             anim = GetComponent<Animator>();
6.         }

I know, that's a simple problem, but I'm more a painter than programmer. :d

 

If you want to zoom in/out the camera you shouldn't be using animations. Animations are for 3d animations or sprite animations as far as I know.

In 3D you can play around with the camera position and the field of view to make a zoom in/out. In 2D you can play around with the position and the size.

 

Hmm, but I can animate the size of the camera using Animator and I am making a 2D game. I just don't know what I should type after "if" in brackets. I want to zoom in/out the camera when destroyed object shows up.

EDIT:

I guess, I can use tags with that destroyed objects, so the animation in camera would start, when the object with that tag will show up, but how the script should look like?

something like this?

Code (CSharp):

1.  
2.   Animator anim;
3.  
4.   if (gameObject.tag == "example")
5.   {      
6.      anim = GetComponent<Animator>();  
7.   }
8.  

 

As I said, movement by animation is only used on specific cases. For example, when you have an animation of a player running.

In this case, you want to zoom in and out a camera, so you'll have to do this via script and not via Animator.

 

Are you sure? I already did it in Animator, here is the screenshot. I just need to know how in the script make it play when destroyed object shows up.

 

You need to setup some transitions in the Animator window. Here is an example of my menu system Animator.



I've got 2 triggers for parameters, Open and Close.
Both animations are set to not loop.
OpenAnim will be played once Open is triggered.
CloseAnim will be played once Close is triggered.
I made it so no animation gets played at the start.

Code (CSharp):

1. Animator anim;
2.  
3. void Start()//or Awake()
4. {
5.      anim = GetComponent<Animator>();
6. }
7.  
8. void Open()
9. {
10.     anim.SetTrigger("Open");
11. }
12.  
13. void Close()
14. {
15.     anim.SetTrigger("Close");
16. }
17.  

This is one way to do it.

 

Of course you can, but you said you want to zoom at an object, not just zoom the camera. You'll need to move the camera to the object position and then change the size, that's why you need to do it via script.

 

No, no, I just need to zoom the camera. I don't need it to zoom at an object. I want it to zoom when that object will show up just in game, I don't even need to see that object on the screen.

Hmmm, so how the script should look like in my case? I want to activate Animator in the camera, when other object is destroyed.

 

Oh I thought you wanted to move it to the gameObject.

It's fine then. With the Animator component make 3 points. First one is the default, middle one should be the zoomed one and third one default again.

When you have that, you should play around with the speed and see which animation speed looks cool.


Lastly, when an object is destroyed, you should call Play() on the Animator component, if clip is loaded.

 

The destroyed object needs to tell the camera it has been destroyed. There are many ways it can be done.

You could send a message to the camera object from the object that gets destroyed.

Code (CSharp):

1. void OnDestroy()
2. {
3.     Camera.main.SendMessage("ZoomIn");
4. }

then in the camera script

Code (CSharp):

1. void ZoomIn()
2. {
3.     anim.SetTrigger("ZoomIn");
4. }
