dist
float dist (float x1,
float y1,
float x2,
float y2)
Returns the distance between two points.
| Parameters | |
|---|---|
x1 |
float |
y1 |
float |
x2 |
float |
y2 |
float |
| Returns | |
|---|---|
float |

distanceToFurthestCorner
float distanceToFurthestCorner (float pointX,
float pointY,
float rectLeft,
float rectTop,
float rectRight,
float rectBottom)
Returns the furthest distance from the point defined by pointX and pointY to the four corners of the rectangle defined by rectLeft, rectTop, rectRight, and rectBottom.
The caller should ensure that the point and rectangle share the same coordinate space.
| Parameters | |
|---|---|
pointX |
float |
pointY |
float |
rectLeft |
float |
rectTop |
float |
rectRight |
float |
rectBottom |
float |
| Returns | |
|---|---|
float |
|
geq
boolean geq (float a,
float b,
float epsilon)
Fuzzy greater than or equal to for floats.
Returns true if a is greater than or equal to b, allowing for epsilon error due to limitations in floating point accuracy.
Does not handle overflow, underflow, infinity, or NaN.
| Parameters | |
|---|---|
a |
float |
b |
float |
epsilon |
float |
| Returns | |
|---|---|
boolean |
|
lerp
float lerp (float start,
float stop,
float amount)
Returns the linear interpolation of between and .
| Returns | |
