Function Documentation

◆ add_weapon()

		py,
		n
	)

{*}	px
{*}	py
{*}	n

◆ check_success()

function speeddown ( )

This function is bind to the decrease button it increases the value of var speed so that animation time is more and hence speed decreases finally.

◆ speedup()

function speedup ( )

This function is bind to the increase button it decreases the value of var speed so that animation time is less and hence speed increases finally.

◆ walk()

function walk ( r )

This function controls the movement of warrior based on the input given.

Exception handling is also done in this function as while moving if warrior steps out of arena alert box is shown

Parameters

{int} r integer determining direction of traversal. 1 => move_up, 2=>move_down() 3 => move_right() 4=> move_left

◆ weapon()

function weapon ( )

This function checks if the gem is collected or not in order.

It sets value of insequence to be true if gems are collected in correct order.

Variable Documentation

◆ gem_found

var gem_found = [false, false, false, false, false]

The list stores info about which gems are collected.

◆ id_order

var id_order = []

it stores the values as the gems are added to the arena.

◆ index

var index = 0

stores the index upto which the gems found are checked while checking in animate part of jquery.
This is required since jquery implements animation through queue.

◆ innerHTML

speed_show innerHTML = speed_dict[speed]

◆ insequence

var insequence = true

it stores true if the gems are collected in sequence else false.

◆ log

console log

Initial value:

= function (message) {
        if (typeof message == 'object') {
            logger.innerHTML += (JSON && JSON.stringify ? JSON.stringify(message) : message) + '<br />';
        }
        else{
            logger.innerHTML += message + '<br />'
        }
    }
})()

◆ logger

var logger = document.getElementById('log')

◆ pos_x

var pos_x = 0

stores the X-coordinate of warrior

◆ pos_y

var pos_y = 0

stores the Y-coordinate of warrior

◆ reloaded

var reloaded = true

check if reloading was done before or not

◆ speed

var speed = 500

For the animation speed of the player.

◆ speed_dict

speed_dict = {250 : "fast", 500 : "medium", "750" : "slow"}

maps speeds in milliseconds to the name corresponding to them.

◆ speed_show

const speed_show = document.getElementById("speed_")

The element in which we have to show speed.
