How can I convert this Ruby Code to JS?

[nio kasgami]

Hey guys I had a Linear code where Galenmereth helped me to create for doing lineart movement more "easily" in Ace...

Now though I want to convert it to MV but I don't know how to properly convert it to JS

here the code

#---------------------------------------------------------------------------- # ○ new method: lineart #---------------------------------------------------------------------------- # * t = Current time (frame) # * b = Start value # * c = Target value # * d = Duration total (frames) # * Returns: Value modified by t def lineart(t, b, c, d) return c*t/d.to_f + b end thanks for any further answer

It's pretty much exactly the same.

Class_Name.prototype.lineart = function(t, b, c, d) {  return c * t / d + b;}

You don't need to_f because JS uses floats by default, and both the old and the new would return a float. The only thing you left out was what class this method belongs to.

in regards to more complicated ruby code I wouldn't.  I would just re-write it from scratch There are tools out there to do this how ever the code they produce is often un readable and unmaintainable.

I approve although this little line's of code do the same's job both in Ruby in JS so no need to rewrite everything's lol

the only big difference would be is I don't need to convert to float

In this case, it's one of Robert Penner's easing functions, which have been translated in a whole bunch of languages, so you could just google for them ^^
