Welcome to the forum!

this works:

` MyBolts1 = new Bolts(7.0, 6.0, 1.0, 2.0, 12.0, 15.0, myImageBolt);`

We can’t run your code

What happens falsely, what do you want to happen instead?

its supposed to be a simple game if the character us hit to minus point if the character evades the bolts you gain a point. game over if the score is -5 and you win if the score reaches 50 (which maybe too complicated)

So is it that some of my false needed to be trues?

Thank you

please format your code posting by pasting it into the

```auto
</> code button

```

of the editor header menu ( context name: Preformatted text )  
it looks like  
```  
type or paste code here  
```

also can use the ``` manually above and below your code.

thank you.

* * *

your code need lots of files to run  
so we can not test it

if you make a version without files  
and sound…  
we might test your logic.
