Code viewer for World: Heads Up Poker AI(unfinish...




//My comments
//I started working on this but after a while realised to deliver anything decent would
//require a very large amount of time and effort.
//Decided to do a simpler game to have a complete deliverable
//My other game was connect 4.
//I choose that as it is easy to see that a simple random AI is of no use against a human


// =============================================================================================
// More complex starter World for WWM
// 3d-effect Maze World (really a 2-D problem)
// Mark Humphrys, 2016.
//
// This more complex World shows:
// - Skybox
// - Internal maze (randomly drawn each time)
// - Enemy actively chases agent
// - Music/audio
// - 2D world (clone this and set show3d = false)
// - User keyboard control (clone this and comment out Mind actions to see)
// =============================================================================================


// =============================================================================================
// Scoring:
// Bad steps = steps where enemy is within one step of agent.
// Good steps = steps where enemy is further away. 
// Score = good steps as percentage of all steps.
//
// There are situations where agent is trapped and cannot move.
// If this happens, you score zero.
//
// Scoring on the server side is done by taking average of n runs.
// Runs where you get trapped and score zero can seriously affect this score. 
// =============================================================================================






// World must define these:
 
const	 	CLOCKTICK 	= 100;					// speed of run - move things every n milliseconds
const		MAXSTEPS 	= 1000;					// length of a run before final score
 





//---- global constants: -------------------------------------------------------

const gridsize = 9;						// number of squares along side of world	   

const NOBOXES =  Math.trunc ( (gridsize * gridsize) / 10 );
		// density of maze - number of internal boxes
		// (bug) use trunc or can get a non-integer 

const squaresize = 100;					// size of square in pixels
const MAXPOS = gridsize * squaresize;		// length of one side in pixels 
	
const SKYCOLOR 	= 0xddffdd;				// a number, not a string 
const BLANKCOLOR 	= SKYCOLOR ;			// make objects this color until texture arrives (from asynchronous file read)




const show3d = true;						// Switch between 3d and 2d view (both using Three.js) 
 
const startRadiusConst	 	= MAXPOS * 0.8 ;		// distance from centre to start the camera at
const skyboxConst			= MAXPOS * 3;		// where to put skybox 
const maxRadiusConst 		= MAXPOS * 10  ;		// maximum distance from camera we will render things
