For those of you familiar with Robert Penner’s easing equations, do you feel any shame using them? I mean, do you think that people who use Penner’s formulas are unoriginal and such?
I like the equations, but I don’t like taking someone else’s code and using it (with credit of course)…but then again, I don’t have the math skills just yet to create my own formulas…hm. So, does anyone see anything wrong with using Penner’s (or anyone else’s) equations?
What’s wrong by using Penner’s equation?
I bought his book, I like it, if I use his script I put like this:
//The following easing is written by Penner.
Why would you reinvent the wheel, anyway? If I use E=mc2 it doesn’t mean that I claim I wrote that.
Most of his equations (at least the originals that I’m familiar with) are just “the way its done.” Want to go to frame two? Use gotoAndPlay(2). Want a linear tween? Use the equation penner used for linear a tween. If you took the time to write it on your own, it’d pretty much be exactly the same. Penner just provides a collection that doesn’t require people to write them out on their own and instead just copy and paste.
It is a formula for movement. What you do with that formula creates the artform.
Also you don’t need to buy the book to get the AS guides:
