1. FightingICE AI Coding
PUJANA P.

2. To Run AI Step 1 Export JAR
MUST use the same name

3. To Run AI Step 2 Put JAR to the game folder

4. AI00: Null

5. Class Structure
@Override
public void close() {
}
@Override
public void getInformation(FrameData arg0) {
}
@Override
public int initialize(GameData arg0, boolean arg1) {
return 0;
}
• runs only once at the end of each game.
• gets information from the game status of each frame
• If fd.getRemaningTime() returns a negative value,
the current round has not started yet.
• More info in Javadoc of AIToolkit.
1 game = 3 rounds (60 sec / round)
• executed only once in the beginning of a game

6. Class Structure
@Override
public Key input() {
return null;
}
@Override
public void processing() {
}
@Override
public void roundEnd(int arg0, int arg1, int arg2) {
}
• receives key inputted from AI.
• It is executed in each frame and returns a value in the Key type.
• executed in each frame
• informs the result of each round.
[not sure] frames / sec

7. AI01: Random
Randomly Press Keys

8. Final Code For Copy-Paste

9. Step 1 Declare Global Variables & Initialization
Key inputKey;// Key class for return.
Random rnd;// is used for getting a random number.
@Override
public int initialize(GameData arg0, boolean arg1) {
inputKey = new Key();
rnd = new Random();
return 0;
}

10. Step 2 Modify Processing
@Override
public Key input() {
return inputKey;
//return null;
}
@Override
public void processing() {
// every key is set randomly.
inputKey.A = (rnd.nextInt(10) > 4) ? true : false;
inputKey.B = (rnd.nextInt(10) > 4) ? true : false;
inputKey.C = (rnd.nextInt(10) > 4) ? true : false;
inputKey.U = (rnd.nextInt(10) > 4) ? true : false;
inputKey.D = (rnd.nextInt(10) > 4) ? true : false;
inputKey.L = (rnd.nextInt(10) > 4) ? true : false;
inputKey.R = (rnd.nextInt(10) > 4) ? true : false;
}

15. Final Code For Copy-Paste

16. Step 1 Declare Global Variables & Initialization

@Override
public int initialize(GameData arg0, boolean player) {
inputKey = new Key();
this.player = player;
frameData = new FrameData();
this.commandCenter = new CommandCenter();
return 0;
}

17. Step 2 Modify Other Part
@Override
public void getInformation(FrameData frameData) {
this.frameData = frameData;
this.commandCenter.setFrameData(this.frameData, player);
}
@Override
public Key input() {
//return null;
return inputKey;
}
Be careful

18. Step 3 Modify Processing
@Override
public void processing() {
if(!frameData.getEmptyFlag()){
if(frameData.getRemainingFramesNumber()>0){
if (commandCenter.getSkillFlag()) {
inputKey = commandCenter.getSkillKey();
} else {

Tips

54. AI05: Switch

55. Final Code For Copy-Paste
1. Copy-Paste, export JAR
2. Test
3. Create “dataaiDataSwitchsignal.txt”
Put 1 as value
4. Test again

56. @Override
public void processing() {
if (!frameData.getEmptyFlag()) {
if (frameData.getRemainingFramesNumber() > 0) {
if (switchFlag) {
randomProcessing();
} else {
copyProcessing();
}
}
}
}
Step 1 Use of Switch

57. @Override
public int initialize(GameData gameData, boolean playerNumber) {
...
file = new File("data/aiData/Switch/signal.txt");
if(!file.exists()){
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
try {
br = new BufferedReader(new FileReader(file));
String line = br.readLine();
System.out.println("signal:" + line);
if (line.equals("1"))
switchFlag = true;
else
switchFlag = false;
br.close();
} catch (IOException e) {
Step 2 Read Switch
2
1

58. public void close() {
try {
System.out.println("myScore:" + myScore);
System.out.println("opScore:" + opponentScore);
if (myScore < opponentScore) {
System.out.println("lose");
pw = new PrintWriter(new BufferedWriter(new FileWriter(file)));
if (switchFlag) {
pw.println("0");
} else {
pw.println("1");
}
pw.close();
} else {
System.out.println("win");
}
} catch (IOException e) {
e.printStackTrace();
}
}
Step 3 Write Switch
