Math Extensions
Ratchet expands on the standard math library to give you a few more functions for convenience. All standard Lua functions are available as well and not listed on this page.
round function
Returns the value of a number rounded to the specified amount of decimal places or to nearest integer by default.
Syntax:
lua
int math.round( float number [, int decimals = 0 ] )clamp function
Clamps a value within a range of values between a defined minimum bound and a maximum bound.
Syntax:
lua
float math.clamp( float value, float min, float max )lerp function
Performs linear interpolation, returning a value between two numbers at a specific increment between 0 and 1.
Syntax:
lua
float math.lerp( float start, float stop, float t )distance function
Calculates a distance between two points in 2D space using Pythagorean theorem.
Syntax:
lua
float math.distance( float x1, float y1, float x2, float y2 )
