Hey guys,
I was messing around today and found a website with some spring mathematics on it. So I put together a spring script. This is to create realistic spring animation. You can run the script with a timer or you can keyframe the "Time" input on the script.
Here's a little explanation of the script:
Time - Link a timer into this or keyframe this input. This drives the animation.
Speed - Naturally this will adjust the speed. If set to one, it runs at the same speed as the timer. So usually less then one will yield smoother animation.
Amplitude - Set this to the amount you want the spring effect to start. For instance, if you set it to 90, the output will start from 90 and decay from there.
Decay - This is how quickly you want the spring movement to decay. Setting a higher number will create a stiffer spring effect.
Floor - This is the number that the spring will finally come to rest to. For instance, if you set it to 0, the output will eventually stop at 0.
Reverse - This will reverse the spring to start from the other direction.
OUT - Link this into one of the matrix inputs for an object (Location, Rotation, or Scale).

Here's the script and a scene that demonstrates a few different ways to use it. Just start the timer. |

I was messing around with a car suspension some months back, I am wondering whether I can use your Spring Animator... thanks for doing this Dele, it gives me something to work from :D

Thanks guys. :)
It might work to simulate car suspension, depending on what exactly you're trying to do. I'm not sure how many real useful purposes this script will have, but I figure it may come in handy for odd things here or there. |

Hmm... I was thinking about taking one of the cars from the library and creating a Low-Rider with those funky jumping effects... :cool:

Here we go. Not really a video (YET) but just modifications to the spring timer stuff.
Per Roman's request, this is the beginning of a lowrider car jumping. More will follow.
This is my first go at the link editor. It could and will look better but this is not too bad for a start. Just follow Dele's instructions: Push the Start Timer button and watch the car Rock!
That's a good question then. How do you create keyframes from a timer type script? Add commands to the script? Most likely...

well that's odd. I guess the car never got loaded. I'll do that tonight. Sorry about that!
