/*
|
|
* Author: Pterolatypus
|
|
* Returns the image of a value on a linear piecewise function defined by given points
|
|
* Force integer causes decimals to be rounded up or down by chance based on their decimal part, i.e. 2.7 has a 70% chance to return 3 and 30% to return 2
|
|
*
|
|
* Arguments:
|
|
* 0: Input value <NUMBER>
|
|
* 1: Function points, must be in descending order by X (input) value <ARRAY>
|
|
* 2: Whether to force integer <BOOLEAN>
|
|
*
|
|
* ReturnValue:
|
|
* Interpolated result <NUMBER>
|
|
*
|
|
* Example:
|
|
* [0.2, [[1,0], [0.5,1], [0,0]]] call ace_medical_damage_fnc_interpolatePoints
|
|
*
|
|
* Public: No
