== Arrays == An array is used to store multiple values in a single variable. Example array: {{{ browser = ["Safari", "IE", "FireFox", "Chrome"] }}} the example given above shows an array with 4 elements (values), the elements are "strings". Each element is seporated by commas: "," Arrays are indexed from 0, meaning the first elements index is 0, the second elements is 1 and so on. An array element can be referenced separately, like so: {{{ browser = ["Safari", "IE", "FireFox", "Chrome"] echo browser[0] }}} The above example will return "Safari" as safari has an index of 0 within the "browser" Array. == Array Functions == |

Arrays
An array is used to store multiple values in a single variable.
Example array:
browser = ["Safari", "IE", "FireFox", "Chrome"]
the example given above shows an array with 4 elements (values), the elements are "strings". Each element is seporated by commas: ","
Arrays are indexed from 0, meaning the first elements index is 0, the second elements is 1 and so on.
An array element can be referenced separately, like so:
browser = ["Safari", "IE", "FireFox", "Chrome"] echo browser[0]
The above example will return "Safari" as safari has an index of 0 within the "browser" Array.

push
Usage: array.push("x")
Adds one or more elements to the end of an array and returns the new length of the array.
Example:
- myArray = ["a","b","c","d"]
- echo "myArray = "+myArray
- returnVal = myArray.push("e")
- echo "myArray = "+myArray
- echo "returnVal = "+returnVal
Result:
- myArray = a,b,c,d
- myArray = a,b,c,d,e
- returnVal = 5
pop
Usage: array.pop()
Removes the last element from an array and returns the value of that element.
Example:
- myArray = ["a","b","c","d"]
- echo "myArray = "+myArray
- returnVal = myArray.pop()
- echo "myArray = "+myArray
- echo "returnVal = "+returnVal
Result:
- myArray = a,b,c,d
- myArray = a,b,c
- returnVal = d
unshift
Usage: array.unshift("x")
Adds one or more elements to the beginning of an array and returns the new length of the array. The other elements in the array are moved from their original position, i, to i+1.
Example:
- myArray = ["a","b","c","d"]
- echo "myArray = "+myArray
- returnVal = myArray.unshift("_")
- echo "myArray = "+myArray
- echo "returnVal = "+returnVal
Result:
- a,b,c,d
- _,a,b,c,d
- 5
shift
Usage: array.shift()
Removes the first element from an array and returns that element. The remaining array elements are moved from their original position, i, to i-1.
Example:
- myArray = ["a","b","c","d"]
- echo "myArray = "+myArray
- returnVal = myArray.shift()
- echo "myArray = "+myArray
- echo "returnVal = "+returnVal
Result:
- myArray = a,b,c,d
- myArray = b,c,d
- returnVal = a
concat
Usage: array.concat()
used to join two or more arrays together.
Example:
boy = ["Luke", "Bob","Jason"]
girl = ["Emma", "Katie", "Chiara"]
uni = ["Jordan","alex","Jessie"]
names = uni.concat(girl,boy)
echo names
Result:
Jordan,alex,Jessie,Emma,Katie,Chiara,Luke,Bob,Jason
sort
Usage: array.sort()
Used to sort the order of array elements.
Example:
- array = ["b", "a", "d", "c"]
- echo array.sort()
Result:
- a,b,c,d
join
Usage: array.join()
Takes an array and joins the elements into one string.
Example:
- array = ["a", "b", "c", "d"]
- echo array.join()
Result:
- "a,b,c,d"
IndexOf
Usage: array.indexOf()
Checks for the first instance of an element and returns its position.
If the item is not found, it will return as "-1"
If the item is present more than once, the indexOf method returns the position of the first occurrence.
Example:
array = ["google", "yahoo", "DuckDuckGo", "Bing"]
echo array.indexOf("DuckDuckGo")
Result:
- 2
lastIndexOf
Usage: array.lastIndexOf()
Checks for the last instance of an element and returns its position.
If the item is not found, it will return as "-1"
If the item is present more than once, the lastIndexOf method returns the position of the last occurrence.
Example:
array = ["google", "yahoo", "DuckDuckGo", "Bing","DuckDuckGo","google"]
echo array.lastIndexOf("DuckDuckGo")
Result:
- 4
reverse
Usage: array.reverse()
Reverses the order of the elements in the array.
Example:
count = ["1","2","3","4","5"]
echo count.reverse()
Result:
- 5,4,3,2,1
splice
Usage: array.splice()
adds or removes elements to or from an array, and returns the removed elements.
Example:
browser = ["Safari", "IE", "FireFox", "Chrome"]
echo browser.splice(2, 2)
Result:
FireFox,chrome
- Safari,IE
slice
Usage: array.slice()
The slice() method returns the selected elements in an array, as a new array object.
The slice() method selects the elements starting at the given start argument, and ends at, but does not include, the given end argument.
Example:
browsers = ["IE", "Chrome", "FireFox", "Safari", "SeaMonkey"]
Good = browsers.slice(1, 3)
Result:
Good = Chrome,FireFox
length
Usage: array.length
Returns the length of an array as an integer.
Example:
array = SearchEnemyCastles(10) echo "length: " + array.length + ", id: " + array[0].id + ", CityName: " + array[0].name + ", userName: " + array[0].userName + ", alliance: " + array[0].allianceName + ", prestige: " + array[0].prestige + ", honor: " + array[0].honor
Result:
length: 19, id: 17894, CityName: RED, userName: SomeN00b, alliance: 422, prestige: 6758, honor: 10495584936
MultiDimensional
Usage: array = [1,["a1","a2","a3"],["b1","b2","b3"],2]
Example:
array = ["bob",["count",1,2,3],["letters","a","b","c"],"bill"]
echo array[1][0]+" The amount of "+array[2][0]"in this array."
echo array[1][1]+". "+array[1][1]
echo array[1][2]+". "+array[1][2]
echo array[1][3]+". "+array[1][3]
echo array[0]+" & "+array[3]+" have been added to the main array also."
Result:
- - count The amount of letters in this array.
- - 1. a
- - 2. b
- - 3. c
- bob & bill have been added to the main array also.
ArrayCollection
This allows multiple arrays, similar to MultiDimentional but Sub-Arrays are also named.
Where as MultiDimentional works using array[0][0], this method allows named sub-arrays.
Usage: array = [ {a:1},{b:2} ]
Example:
array = [ {a:1},{b:2} ]
echo array[0].a
echo array[1].b
Result:
- - 1
- - 2
substr
Returns a select section of a string.
options are required in the substr brackets "substr(options)"
Usage: string.substr()
In the Example below the options are "0, 4" this will start the new string at char "0" of the existing string, and end it 4 chars after.
Example: theString = "NEAT Bot"
echo theString.substr(0, 4)
Result:
- NEAT
