Functions are NOT case sensitive Functions enforce a strict type system, all strings/text must be surrounded by double quotes or it will be treated as the name of a variable. Parameters in [] are required, parameters in <> are optional. Booleans are either true or false (or conditions), Strings are pieces of text (Strings must be surrounded by quotes) and Number are... well... numbers...

Type casting

int([Text]) - returns the number equavilent of the provided text (ex. "1" returns the number 1, "20" returns the number 20, etc.)
int([Character]) - returns the ascii of the provided Character
str([Anything]) - returns the text equavilent of the provided value (ex. the number 1 returns "1", the boolean true returns "true", etc.)
char([Number]) - returns the Character located at the provided index in the ascii Character table.

Reading variables

getVar([String variable]) - returns the variable with the given name (ex. fps, key_h).
getNumber([String variable]) - returns the Number variable with the given name.
getString([String variable]) - returns the String variable with the given name.
getBoolean([String variable]) - returns the Boolean variable with the given name.

Math helper functions

Trigonometry

Yeah, I have no idea how trigonometry works so this is just a list with no explanation.

sin([Number])
cos([Number])
tan([Number])
asin([Number])
acos([Number])
atan([Number])

Other

abs([Number]) - returns the positive value of the provided number (ex. abs(1) returns 1, abs(-1) returns 1, etc.)
floor([Number]) - returns the closest round number that is either equal to or less than the provided number (ex. floor(7.25) returns 7, floor(8) returns 8, floor(6.9) returns 6, etc.)
ceiling([Number]) - returns the closest round number that is either equal to or greater than the provided number (ex. ceiling(7.25) returns 8, floor(8) returns 8, floor(6.9) returns 7, etc.)
sqrt([Number]) - returns the square root of the provided number (ex. sqrt(4) returns 2)
pow([Number], [Number]) - returns the first number to the power of the second number (ex. pow(2,8) returns 256)
min([Number], [Number]) - returns the lowest of the two provided numbers (ex. min(1,20) returns 1)
max([Number], [Number]) - returns the highest of the two provided numbers (ex. max(1,20) returns 20)
truncate([Number], [Number]) - returns the first number with the decimal cut off beyond the point provided in the second number (ex. truncate(1.69, 1) returns 1.6)
rng([Number], [Number], <Number>) - returns a random number between the first two numbers, if a third number is provided it will be used as the seed

Misc

exists([Text]) - returns true if a file named the provided text exists within Hudder's config folder otherwise it returns false (ex. exists("hud") will return true)
strwidth([Text]) - returns the width of the provided text if drawn on screen with a scale of 1
map() - returns a Java HashMap (If you don't know what that means then it has no use for you)
array([Number], [Any]) - creates an array of the provided size filled with the provided value.
toBinaryString([Number]) - returns the binary value of the provided Number in string form (ex. toBinaryString(5) will return 101)

The following functions are deprecated. Please avoid using them as they may be removed in a future update.

Inventory information (Deprecated, see Item components)

itemname([Number]) - returns the name of the item in the provided slot
itemdurability([Number]) - returns the durability of the item in the provided slot
itemmaxdurability([Number]) - returns the maximum durability of the item in the provided slot
itemcount([Number]) - returns the count of items in the provided slot
itemmaxcount([Number]) - returns the maximum count of items in the provided slot (ex. if an enderpearl is in the slot it will return 16)

Text manipulation (Deprecated, see Strings)

concat([Text], [Text]) - returns the combination of the provided texts (ex. concat("1","2") returns "12")
substring([Text], [Number], [Number]) - returns the text between the 2 provided points (ex. substring("Long text", 1, 4) returns "ong")
repeat([Text], [Number]) - returns the provided text repeated the requested amount (ex. repeat("Repeat", 2) returns "RepeatRepeat")
length([Text]) - returns the length of the provided text (ex. length("Length") returns 6)
