As far as I can tell from your problem definition, you're overthinking it:
ConcurrentMap is overkill because you won't be writing concurrently. As long as you pass a memory barrier of some sort, your other threads will read correctly.

I have a little mario game I started working on realize that it's format is very messy, can anyone critique my code on how to make it better, faster, neater, easier to access.
I'm quite a noob so finding mistakes shouldn't be too diffuclt.
Here it is:

from my recent post it had some negatives to fix hehe :P I think this should be well structured and written for you JavaScript heroes ;)
How does this code look to you? If something needs to be changed please tell me :)

Simple version: My Game consists of two players; Every Player can do actions, I need to be able to get the opponent (the other player) inside each Player.
@Vogel612 I asked an on-topic question on Programmers, but it doesn't help me that much as it is more a general statement, fine-tuned advice can only be given after seeing my concrete code
Suppose I have the following two classes to start off with:
public class Game {
private final Player self;
private final Player opponent;
public Game(final Player self, final Player opponent) {
this.self = Objects.requireNonNull(self);
this.opponent = Objects.require...
It would still have a cicular dependency (a game has players, a player has a game) even though not at compile time, but I'm not seeing a concrete way to solve it
Well if you want to keep it out of the Game, you need to connect the Players somehow.. But I'd rather not have a Player have a Player, but some EventBus-like structure to notify of changes..
@Vogel612 Yes, I haven't taken that law into consideration too much. It's freakin' hard making a TCG as it is, I don't need Law of Demeter to make it even worse for me :)
@skiwi In one way or another, I think so yes. If you would assign the game twice to a player with different games, then you're screwed. However, the easiest way to avoid it is to: Don't do it.
@skiwi Two AIs FTW! Having AIs playing against each other makes some testing so much easier.
I want to erase all memory in a container. Currently I'm using this :

void clear_mem(Cont &container)
{
while (!container.empty())
{
delete container.back();
container.pop_back();
}
}
Should the operation of deleting the memory held by the ...
@chillworld Hearthstone is kinda like Magic, but simpler, it only has creatures and sorceries as cards. My problem is if you have a minion (creature) in play that says "other friendly minions have +1/+1", or a minion that says "This minion's attack is equal to it's health". All these "enchantments"/"rules" makes making a TCG game hard. If it were one-time only effects, that wouldn't be a problem, but this is static effects, as long as the minion is in play, that rule applies.
@Vogel612 You tell me once I post the code for review :)
@Vogel612 The "Every time an enemy minion dies" is not a problem, as that's a clear trigger-action. The "All murlocs on your side has x/y" is quite difficult, yes.
@Vogel612 But the Action isn't really an action, it's a static effect. "All murlocs on your side have +1/+2" is always there. It's not applied once, it's just there...
@Vogel612 Questing Adventurer? Indeed. The opponent tends to focus on removing that very early on. Or they wait until it gets bigger and then just use Silence on it.
@Vogel612 There is no "Neighboring minions have +1/+2 and taunt", taunt is only given as a one-time action. It's applied as a battlecry, which triggers when you play the minion from hand.
@Vogel612 Yes, silence removes already-applied buffs. All already-applied buffs, except the static effects (unless you silence the minion that gives the static effect).
private Player getOpponent() {
return game.getPlayers().filter(x -> x != this).findFirst().orElseThrow(() -> new IllegalStateException("No opponent has been found."));
}
@skiwi That's almost like I do it, except I don't use streams. Also consider what would happen if you have a 3-player game and you want to get the next player.
@skiwi Yes, it is. I sometimes do that, but when I know the cards that both players have it's easy to think "I shouldn't play this card because the opponent has that card"
I'm before implementing quicksort as an exercise.
I'm trying to do this generic, for any data type that can be.
What aspects I should consider to do so?
Until now I'm wondering whether the quicksort algorithm should reside in static service class called sorter, or maybe should I export this lo...
I see Netbeans patched their issue in Supplier<IllegalStateException> exceptionSupplier = new IllegalStateException("No opponent has been found");, where it would complain that the new instance was ignored
@skiwi At the moment: I don't. I have three big TCGs at the moment, two of which are just meant to be clones of existing games. And the third one is not meant to be balanced.
@skiwi You will see later, when I make the third one available, why that one isn't meant to be balanced :)
@skiwi I have however used my Fighting code (see my CR question) to make sure that when adding a cheat card to a deck, a player drastically increases the win %. So I believe that can be used to balance things. That requires though that you make AIs and let them play, unless you want to go through and play 1000 games manually :)
I don't think it's a good thing that I can put monsters on an already occupied spot and that the original monster just disappears and is never to be found again?
OK, so, you ever have one of those moments when you do something stupid, and you don't realize what you are doing, and everything you do compounds it.... well, I have one... happening right now ....

@rolfl I don't know... When fully JITted (so performance matters) I suppose they can come close to the performance, but well obviously there's going to be overhead
@SimonAndréForsberg If you do something that's not allowed, my goal is to surely always throw some kind of exception to make sure a failing program can't live on
@skiwi Have two methods in your actions, one for checking if it's allowed, one for actually performing it: boolean actionIsAllowed(); void onPerform();
What is not so sane is that I have a method public int increaseHitpoints(final int increment) { } on MonsterCard, which has 100% test coverage, yet the return value is never tested.
It shouldn't be too bad, but even if it's 100% there can still be a sh*tload of bugs...
@SimonAndréForsberg if you test something that's connected to it, you're maybe not doing it right, if you need to depend on the method to return the expected value without having it tested...
This code is awesomely written. I still have a few really small remarks:
Ordering members:
If openness separates concepts, then vertical density implies close association. So lines of code that are tightly related should appear vertically dense.

@Vogel612 I might be doing it wrong, but I think that if I would test each and every detail it would take longer time to get progress (refer to @skiwi for reference)
@Vogel612 Absolutely, I just found out that a Mage can win turn 2 here because I wasn't decreasing the mana available when the mage were using its Hero Power. But when I find those bugs, then I add a test case just for them.
@Test
public void heroPowerCost() {
game = testGame(HStoneClass.MAGE);
reachMana(2);
assertDamageToOpponent(1, game.getCurrentPlayer().getHeroPower());
useFail(game.getCurrentPlayer().getHeroPower());
}
@Vogel612 I don't think you can entirely avoid using manual testing. Manual testing for me is to discover the edge-cases that your code currently doesn't handle (or test).
I have following code, in which i have to handle exception for 2 statements,
2nd line and 4th line
if(re.search("USN:.*MediaRenderer", datagram, flags=re.IGNORECASE)):
deviceXML = re.search("LOCATION:(.*.xml)", datagram, flags=re.IGNORECASE).group(1) # this line
root = El...
@Vogel612 Then you'd have to think about each and every situation your code can go wrong, I believe you will always miss a case. Like when I first tested my HStone code manually, I discovered that I could use a minion on the battlefield to attack a minion on the opponent's hand. Not quite what was planned. Would you remember to add a unit test for that?
@Vogel612 Yes, being stuck with older Java is a pain. I'm glad I can use some Java 8 features in Android and GWT now, all that's missing now is the Streams (and java.time package, but Streams are more important)
@SimonAndréForsberg Did you add a unit test for the bug report after you discovered it though? The amount of AAA companies reintroducing obvious bugs with patches is horrible.
