When I tap my screen the 2d animation appears but when it ends it stays there, how do I make it disappear?

Im using this code to make it appear:

// Makes the sprite visible by changing the alpha to 1

gifAnimation.getMaterial(0).getPass(0).baseColor = new vec4(1, 1, 1, 1);

Hi there, probably the easiest way to make an anim disappear is to simply disable the SpriteVisual. Here's a script that takes in a Sprite Visual via the Inspector and plays the animation once. Then, it registers a callback for when the animation finishes. Upon finish, it disables the sprite visual. Hope that helps!
```
// -----JS CODE-----
//@input Component.SpriteVisual myAnimation

script.myAnimation.enabled = true;
script.myAnimation.getMaterial(0).getPass(0).baseTex.control.play(1, 0.0);
script.myAnimation.getMaterial(0).getPass(0).baseTex.control.setOnFinish( onAnimationFinished );

function onAnimationFinished()
{
    script.myAnimation.enabled = false;
}
```

It says: cannot write property 'enabled' of undefined at [anon] (script:16) preventsyield

Make sure you've linked the animation to the script in the Inspector.
- First, add the script to an empty game object
- Select the object with the script in the Objects panel
- In the Inspector panel, find the script and click the "myAnimation" field
- Find the 2D animation in your scene and select it
- Press refresh in the Preview panel and the error should go away
Cheers,

Travis

Thank you for your answer :) It worked but when I press it again you only hear the sound from the animation, how can I make it that when I press the screen again it replays the animation with the sound?

I found something and everything is finished but now my file is to big and if I remove frames the file becomes bigger for some reason.

When importing a 2D animation, one or more sprite sheets are created. One way to reduce the size of the animation is to set the File Count parameter to a lower number on import (which represents the number of resulting animations).

Besides file count, likely your resulting sprite sheets created in the animation tool aren't compressed. There are two ways to fix this.

1) Reimport your animations and lower the quality which will use compression (bottom right hand corner of the animation import tool). Try to use a low number here for a smaller file size

2) You can also compress your already exported animations. To do this, go to your projects folder on your computer. There you will see a Public folder. In the Public folder, there should be another folder (named the animation name) which has your exported animation. Take all the images in there and run them through https://tinypng.com/ which will compress them quite a bit. Replace the images with the compressed ones. Your lens should now fit within the 4 mb limit
