lerp()

Examples
a = 20
b = 80
c = lerp(a, b, .2)
d = lerp(a, b, .5)
e = lerp(a, b, .8)
beginShape(POINTS)
vertex(a, 50)
vertex(b, 50)
vertex(c, 50)
vertex(d, 50)
vertex(e, 50)
endShape()
x1 = 15
y1 = 10
x2 = 80
y2 = 90
line(x1, y1, x2, y2)
for i in range(10): 
    x = lerp(x1, x2, i/10.0) + 10
    y = lerp(y1, y2, i/10.0)
    point(x, y)
Description Calculates a number between two numbers at a specific increment. The amt parameter is the amount to interpolate between the two values where 0.0 equal to the first point, 0.1 is very near the first point, 0.5 is half-way in between, etc. The lerp function is convenient for creating motion along a straight path and for drawing dotted lines.
Syntax
lerp(start, stop, amt)
Parameters
startfloat: first value
stopfloat: second value
amtfloat: float between 0.0 and 1.0
