hey ya’ll! My code is almost complete but I am having a problem with one of my classes not initializing a function I made. Specifically the “kill” function ( atarget.kill(); ). it says that kill() expects parameters like “kill(Ball)” however when I put Ball in it doesn’t work. Same with aBall. anyone know what is wrong? here is the code in question.  
from a separate class  
void kill(Ball aBall){

```
if(bottom>=aBall.c1d+2.5 &&front>=aBall.c1d+2.5){
   isCrashed=true;
   println("hit");

```

}  
}  
from the constructor

for (target atarget : targetList) {

```
atarget.render();
atarget.wallDetect();
atarget.move();
atarget.reset();

```

//where the problem is  
atarget.kill();

```
for (laffey aLaffey : laffeyList) {
  aTarget.crash(aLaffey);
}
//println(aTarget.isCrashed);

```

}  
}

Those code pieces are hard to put together and I can’t say just based on them what’s wrong. My guess is that your if statement `if(bottom>=aBall.c1d+2.5 &&front>=aBall.c1d+2.5)` isn’t working as you expect.
