Quartic movement in WorldsPlayer

Assumptions: Start at 0, time = t goes from 0 to 1

let b = end of move action
let c = end of 1st SetPoint3Action
let d = end of 2nd SetPoint3Action
let e = end of 3rd SetPoint3Action

let d(t) = (e-d)t + d
let c(t) = (d(t) - c)t + c
let b(t) = (c(t) - b)t + b
let p(t) = b(t)t


p(t) = ((((((e-d)t + d) - c)t + c) - b)t + b)t

p(t) = -bt^2 + bt - ct^3 + ct^2 - dt^4 + dt^3 + et^4

p(t) = (e-d)t^4 + (d-c)t^3 + (c-b)t^2 + bt

High jump (1 second instead of 6):

p(t) = 150(1-(1-2t)^4)

p(t) = -2400t^4 + 4800t^3 - 3600t^2 + 1200t

e-d = -2400
d-c = 4800
c-b = -3600
b = 1200
c = -3600 + 1200 = -2400
d = 4800 + -2400 = 2400
e = -2400 + 2400 = 0

b = 1200
c = -2400
d = 2400
e = 0
