I don't understand what's wrong, and how i can call "isCollision" method. In addition i have a bug because i didn't have PLAYER matrix, that i had to get in the part 16.(I coppied ENEMY matrix and renamed it as PLAYER 😅 )Why the 2nd task don't accept this part of code? : if(bullets.isEmpty()) { return; } What's wrong in this part of code ? : else if(isAlive == true) { // for(Bullet a : bullets) { // a.isCollision(ship); // } }

Last condition not validating. Tried everything Not sure what is going on with the last requirement for validation. I'm not even 100% sure what it conditions are even asking me to do. Then in the text it is suggesting using setPoint() but it didn't even ask us to make a return value for that method. Thanks in advance for your time.
