Develop your AI

Introduction

Your AI must be developed using Java-Script, it must include CustomPlayer() definintion and 2 functions:

• init
• turn

function CustomPlayer(){
	this.init = function(team, player, match){
		return ;
	};
	this.turn = function(status){
		return ;
	};
}

Required functions

Function init(team, player, match)

Called before the start of the match 1 time for each player.

Used to ask to AI the starting position of its players.

• parameters

  • team (number) can be 0 or 1; represents the team you are on.
  • player (number) integer from 0 to 10; represent the index of the player in the team. Note that player 0 will be you goalkeeper.
  • match (object) containing following values:

    match.MAXX		// (number) the highest X coordinate of the playing field
    match.MAXY		// (number) the highest Y coordinate of the playing field
    match.MAXSPEED		// (number) the maximum speed that a player can achieve by speeding up
    match.MAXVARIATION	// (number) the maximum change in speed in a frame
    match.INFLUENCEZONE	// (number) the maximum distance at which a normal player (or goalkeeper outside his bonus limit) can attempt a kick
    match.GOALKEEPERINFZONE	// (number) the maximum distance at which a goalkeeper inside his bonus zone can attempt a kick
    match.GOALKEEPERLIMIT	// (number) the maximum X axis distance from his team's goal in which a goalkeeper is granted his bonuses
    match.MAXBALLSPEED	// (number) the maximum speed that a player can set on the ball with a kick
    match.GOALSIZE		// (number) the width of the goal
    match.GOALCOORDS	// (object) array of two elements, containing the Y coordinates at which the goalposts are
      match.GOALCOORDS[0]	  // (number) Y coordinate of first goalpost
      match.GOALCOORDS[1]	  // (number) Y coordinate of second goalpost

• return

  an array defined as follows:

   [
     value,	// (number) containing start position on x axis of this player
     value	// (number) containing start position on x axis of this player
   ]

Function turn(status)

Called during the match 1 time for each player in every timeframe.

Used to ask to AI the speed variation of its players and their kick attempts.

• parameters

  • status (object)

    status.ballStatus		// (object) contains the status of the ball
      status.ballStatus.x		  // (number) X coordinate of the ball
      status.ballStatus.y		  // (number) Y coordinate of the ball
      status.ballStatus.speedX	  // (number) speed of the ball on the X axis
      status.ballStatus.speedY	  // (number) speed of the ball on the Y axis
    status.teamsStatus		// (object) array contains 2 arrays, stores the position and speed of all players (team=[0,1]) 
      status.teamsStatus[team]	  // (object) array contains team's players position and speed (player=[0,1,2,3,4,5,6,7,8,9,10])
        status.teamsStatus[][player]    // (object) object contains player position and speed
          status.teamsStatus[][].x        // (number) X coordinate of the player on team team with number player
          status.teamsStatus[][].y        // (number) Y coordinate of the player on team team with number player
          status.teamsStatus[][].speedX   // (number) speed of the player on team team with number player on the X axis
          status.teamsStatus[][].speedY   // (number) speed of the player on team team with number player on the Y axis
          status.teamsStatus[][].distance // (number) distance between the player and the ball

• return

  an object defined as follows:

   {
     player:
     {
       deltaSpeedX: value,	// (number) containing the speed variation required on y axis for this player
       deltaSpeedY: value	// (number) containing the speed variation required on y axis for this player
     },
     ball:
     {
       thisspeedX: value,	// (number) containing the speed this player try to impress to the ball on x axis
       thisspeedY: value	// (number) containing the speed this player try to impress to the ball on y axis
     }
   }
