Description

This contains the list of built-in gdscript functions. Mostly math functions and other utilities. Everything else is expanded by objects.

Member Function Description

sin

• float sin ( float s )

Standard sine function.

cos

• float cos ( float s )

Standard cosine function.

tan

• float tan ( float s )

Standard tangent function.

sinh

• float sinh ( float s )

Hyperbolic sine.

cosh

• float cosh ( float s )

Hyperbolic cosine.

tanh

• float tanh ( float s )

Hyperbolic tangent.

asin

• float asin ( float s )

Arc-sine.

acos

• float acos ( float s )

Arc-cosine.

atan

• float atan ( float s )

Arc-tangent.

atan2

• float atan2 ( float x, float y )

Arc-tangent that takes a 2D vector as argument, retuns the full -pi to +pi range.

sqrt

• float sqrt ( float s )

Square root.

fmod

• float fmod ( float x, float y )

Module (remainder of x/y).

fposmod

• float fposmod ( float x, float y )

Module (remainder of x/y) that wraps equally in positive and negative.

floor

• float floor ( float s )

Floor (rounds down to nearest integer).

ceil

• float ceil ( float s )

Ceiling (rounds up to nearest integer).

round

• float round ( float s )

Round to nearest integer.

abs

• float abs ( float s )

Remove sign (works for integer and float).

sign

• float sign ( float s )

Return sign (-1 or +1).

pow

• float pow ( float x, float y )

Power function, x elevate to y.

log

• float log ( float s )

Natural logarithm.

exp

• float exp ( float s )

Exponential logarithm.

isnan

• float isnan ( float s )

Return true if the float is not a number.

isinf

• float isinf ( float s )

Return true if the float is infinite.

ease

• float ease ( float s, float curve )

Easing function, based on exponent. 0 is constant, 1 is linear, 0 to 1 is ease-in, 1+ is ease out. Negative values are in-out/out in.

decimals

• float decimals ( float step )

Return the amount of decimals in the floating point value.

stepify

• float stepify ( float s, float step )

Snap float value to a given step.

randomize

• Nil randomize ( )

Reset the seed of the random number generator with a new, different one.

randi

• int randi ( )

Random 32 bits value (integer). To obtain a value from 0 to N, you can use remainder, like (for random from 0 to 19): randi() % 20.

randf

• float randf ( )

Random value (0 to 1 float).

rand_range

• float rand_range ( float from, float to )

Random range, any floating point value between 'from' and 'to'

rand_seed

• Array rand_seed ( float seed )

Random from seed, pass a seed and an array with both number and new seed is returned.

deg2rad

• float deg2rad ( float deg )

Convert from degrees to radians.

rad2deg

• float rad2deg ( float rad )

Convert from radias to degrees.

linear2db

• float linear2db ( float nrg )

Convert from linear energy to decibels (audio).

db2linear

• float db2linear ( float db )

Convert from decibels to linear energy (audio).

max

• float max ( float a, float b )

Return the maximum of two values.

min

• float min ( float a, float b )

Return the minimum of two values.

clamp

• float clamp ( float val, float min, float max )

load

• Object load ( String path )

Load a resource from the filesystem, pass a valid path as argument.

inst2dict
