# AlienWar
This game takes place in a very crowded planet where aliens are the superior race. Your task is to create your own alien and beat all other.
## The Board
It is a 2 dimensional board.  
The length of one side of the board is `Math.ceil(sqrt(species * 100 * 2.5))` = ~40% of board used.
The board is a planet, so if you walk out of the map in the west, you come back in the east. If you walk out in the north, you will find yourself in the south.
## Abilities
Each species on the planet has abilities. Here they are:
```
**Name**        **Benefit**
life        HP = *lifeLVL* * 5 (reduces with every hit you take, 0 = dead), base HP = 10
strength    Your hits do a random int in range [1 to strengthLVL] damage
defense     Randomly select int in range [0 to (50 / *defenseLVL* + 1)], if int == 0 then dodge next attack
vision      Gives you *visionLVL*/2 fields around you vision
cleverness  Blurs (increases) every ability randomly in range [0 to *clevernessLVL*/2] when sending to other aliens
```
## The Game
* There will be 100 instances of each submission.
* After instancing, each alien can set 10 ability points in total. You can set different points for every instance.
* If you set more than 10 points, the instance dies.
* A game consists of 1000 rounds. Each round:
	+ Every alien has to return a move via `move(char[] fields)`. This includes Move.STAY.
	+ If several aliens are on a field, 2 will be randomly selected:
		- If both agree on peace (return false in `wantToFight`) they will stay where they are, else they will fight.
		- This loops until only one alien stays on a field or all agree on peace.
* If an alien kills something, **he gets 1/5 of each of his enemies abilities**. The winners HP will be refilled with 2\**enemyLifeLVL*.
* **Winner is the one with the most abilities** (sum of abilities of living aliens).
## Fights
Both aliens will hit each other "at the same time", this means if you kill the other alien, he still can hit you one time.
Dodging: Before you get hit, the game will calculate if you can dodge the attack by using `rand.nextInt(50 / defenseLvl + 1) == 0`. **defenseLvl will never be greater than 50** when calculating your dodge-skills (hence maximum dodge-chance is 50%).
Hitting: If you don't dodge the attack, you will get hit and your HP will be reduced by `rand.nextInt(enemy.getStrengthLvl()) + 1`.
A fight ends when either one or both alien involved are dead. The winner, if one exists, gets the reward.
## Gamerules
* Base level for every ability (without giving any ability points) is 1 (base HP is 10).
* The values sent when asked to fight are **life (not HP!), strength, defense and vision**-levels.
* Cleverness is NOT sent when asked to fight.
* All floating numbers will be ROUNDED to nearest integer when using/sending them, but stored and increased as float.
* Maximum dodge-chance is 50%. Otherwise fights may never terminate.
## The Prey
There are 5 species which are already on the field. Since they are prey, they choose not to fight when asked to.
```
Whale:       lvl 10 life            Stays   
Cow:         lvl 10 strength        Random move
Turtle:      lvl 10 defense         South west
Eagle:       lvl 10 vision          Examines fields, tries to avoid danger      
Human:       lvl 10 cleverness      North east
```
They will be represented with their first letter (i.e. `W` for whale) in the map (Aliens with `A`, empty fields with a whitespace `' '`).
## Additional Rules
* Reflection is disallowed.
* Interacting (instancing etc.) with other aliens is disallowed.
* Writing/Reading external resources like files or databases is also disallowed.
* Only Java (version 1.8) submissions allowed (Java is rather easy, and you don't have to be an expert for this game).
* All submissions must extend the alien-class and will be placed in the alien-package.
* I will accept the best alien on 19th of July. All aliens submitted by 12:00 UTC that day will be tested.
* Maximum 3 submissions per user since there are already very many aliens.
## Example of an alien
```
package alien;
import planet.Move;
public class YourUniqueNameHere extends Alien {
    public void setAbilityPoints(float[] abilities) {
        abilities[0] = 2; //life
        abilities[1] = 2; //strength
        abilities[2] = 2; //defense
        abilities[3] = 2; //vision
        abilities[4] = 2; //cleverness
    }
    public Move move(char[][] fields) {
        //you are in the middle of the fields, say fields[getVisionFieldsCount()][getVisionFieldsCount()]
        return Move.STAY;
    }
    public boolean wantToFight(int[] enemyAbilities) {
        //same order of array as in setAbilityPoints, but without cleverness
        return true;
    }
}
```

# Manager
Here's a manager. Naturally, the cleverness is 0 and he always strives to go where the sun don't shine. And, of course, he will only fight the weak and is very good in dodging trouble:
```
public class Manager extends Alien {
    private static final int STRENGTH = 5;
    @Override
    public void setAbilityPoints( float[] abilities ) {
        abilities[/* strength   */ 1] = STRENGTH;
        abilities[/* defense    */ 2] = 5;
        abilities[/* cleverness */ 4] = 0; // just to make sure
    }
    @Override
    public Move move( char[][] fields ) {
        return Move.WEST;
    }
    @Override
    public boolean wantToFight( int[] enemyAbilities ) {
        return enemyAbilities[1] < STRENGTH;
    }
}
```

## CartographyLongVisionAlien
This Alien is a consistant performing variant of one of my attempts to produce an alien that is of winning potential. 
It has initial 5x5 vision which it uses to build up an internal map of the surrounding area giving it superior enemy avoidance ability.
In my testing of 100 rounds, on average, It sneaks ahead of all other aliens. (09/07/2014)
**UPDATED GIF showing the repell/attract field effect**
I have modified the Game code to produce animated GIFs of the simulation. You can view such a simluation [here](https://drive.google.com/file/d/0B9i-DPAdw_3YUkdLNlEybjlfbEk/edit?usp=sharing)

  * This Alien attempts to map the visible and guess the movements within the immediate non-visible area around the alien.
  * To this end, the alien can initially see 5x5 grid. It applies weights on the cells of its internal map based on the 
  * prey/alien/blanks within its field of view. It then performs a simple blur to guess movements and then chooses the optimum move

# Choose Your Battles
This alien runs away from other aliens, but runs towards prey (so long as that wouldn't take it towards aliens).
I used a genetic algorithm to help me choose the starting values. The results suggest we should rely on strength and life to get through early battes. Vision is useful later, but we can pick that up from vanquished foes.
We only fight battles we think we can comfortably win - we estimate how many moves it would take to kill our alien, how many it would take to kill our enemy, and only join the battle if it we're "twice as hard" as our opponent.

## Junkie
This alien is addicted to *something*. He starts the war on a pretty nasty fix.
While his fix is going strong (`fix > 3`) he is pleasantly content to sit in his stupor and is up for anything.
However, once his fix starts to wear off (`fix <= 3`) he starts stumbling around in no discernible direction trying to figure out what happened. If asked to fight, he becomes cautious and only fights if he thinks he can win. 
Once his fix runs out, being the addict he is, he must restart the vicious cycle.
```
public class Junkie extends Alien {
    private int fix = 10;
    public void setAbilityPoints(float[] abilities) {
        abilities[0] = 4; //life
        abilities[1] = 3; //strength
        abilities[2] = 3; //defense
    }
    public Move move(char[][] fields) {
        fix -= 1;
        if (fix == 0) {
            fix = 10;
        }
        else if(fix <= 3 && fix > 0) {
            return Move.getRandom();
        }
        return Move.STAY;
    }
    public boolean wantToFight(int[] enemyAbilities) {
        if(fix > 3) {
            return true;
        }
        // Am I stronger than their defense and can I withstand their attack?

## Bender "Bending" Rodriguez
I was pretty liberal with code comments. You can read them in context to see what is going on, but I'll also add some snippets below.
### Summary
> 
> This alien operates on the principle that killing puny Humans is easy and inflates your perceived strength, which will intimidate other aliens into steering clear.
> 
> 
> Whales and Eagles are also bendable. =)
>

The original impetus behind Bender was a misunderstanding of the game shape. Namely: I thought it was a cylinder where easy-prey Humans would get trapped at the north end. Bender was going to beeline the north map edge and travel west, gobbling up the Humans. The world turns out to be a torus, so the modified version you see here attempts to intercept Humans in their north-easterly migration instead.
### Movement

> 
> * For the prey whose movement is known, we add their desirability to the square at which they will be next turn.
> * For those we do not, we divide their desirability equally among the squares that they may move to next turn.
> 	+ Aliens get a bonus negative to their existing square because of banana peels.
>

> 
If you don't find anything interesting nearby, get a sense of whether south, west, or southwest is a more promising option.
Picking one or two prevailing directions lessens the chance that any given Bender will come across any of his compatriots, and picking a direction counter to his main prey should help him kill all humans faster.
I could probably tweak the numbers in the desirability matrix with [James\_pic's genetic algorithm](https://codegolf.stackexchange.com/a/32889/26867) for even better outcomes, but I don't know how to do that.
### Aggressiveness
Bender mostly targets prey, and is pretty conservative with his `wantToFight`. Anyone over Strength 4 is shunned *unless* you think you're dealing with a clever human. Clever humanity is demonstrated by having more Defense and Vision than an alien is likely to have. It's adjusted over the course of an instance by Bender's own ability stats, to account for aliens killing turtles and eagles.

# Warrior
This is a very simple minded alien who just wants to fight. He doesn't care about his enemies nor about his surroundings.
```
public class Warrior extends Alien {
    public void setAbilityPoints(float[] abilities) {
        abilities[0] = 5;
        abilities[1] = 5;
    }
    public Move move(char[][] fields) {
        return Move.getRandom(); //enemies are everywhere!
    }
    public boolean wantToFight(int[] enemyAbilities) {
        return true; //strong, therefore no stronger enemies.
    }
}

You now have someone to test your own alien against.

# Rogue
Like other's have said, I am using the Eagle's movement to some degree. Rather than try to make a winning alien (My best ideas were already taken D:), I decided to make an alien with some character! My alien is a hired gun oblivious to the alien war, and is only on this planet to hunt the filthy human who has skipped out on his death stick debt. My alien will search the planet for the human, and continue to trail behind the human without killing him. Once an alien is seen near him, he will then try to quickly kill the human, and face off against this new foe with "luck on his side" from his completed task.

        }
      else {
        return false;
      }

```
The code is centered around the idea that I should sprint towards the human. Once I beat him, I then wrap around to the southwest, where I will look for the turtle.
**EDIT :** Oh, and about the turtle thing...my alien doesn't like them, so it's totally canon you guys.

Crash landed and just trying to survive. Survives mostly by it's agility and intelligence and counts every scar, considering carefully if it's worth it to start a fight or not. The survivor starts off just hunting and trying to avoid all those other aliens with their big weapons but as it gets more bold may start to go after them. When it really gets going it won't care who it's facing anymore.

# FunkyJack
Just for kicks, here's another entry with a slightly different approach. This one is only focused on avoiding fights. This isn't really a viable strategy due to being surrounded by enemies in the first couple of rounds. 40% of squares are occupied in the first round so on average you will be immediately adjacent to 3-4 enemies. But when increasing the initial empty squares to 12.5 times the species rather than 2.5 times the species it gets an average survival rate of 98.5%.

# Guard
Stack life, buff strength & defense, then stay put. Only attack if the opponent seems to be aggressive (defined as `strength` being greater than 2):
```
public class Guard extends Alien{
    public void setAbilityPoints(float[] abilities){
        abilities[0] = 6;  // life
        abilities[1] = 2;  // str
        abilities[2] = 2;  // def
        abilities[3] = 0;  // vis
        abilities[4] = 0;  // clv
    }
   
    public Move move(char[][] fields){
        return Move.STAY;
    }
    
    public boolean wantToFight(int[] enemyAbilities){
        return enemyAbilities[1] >= 3;
    }
