Rigging Items TF2

GhostDetector

How do I rig an object? And is there a way to rig an object so it starts flying backwards when walking or running? Or must the item be static.

I think the closest thing for what your looking for is called "jigglebones", but I'm not sure.. You should wait for more opinions

You'll need to decompile the character rigs, then import one into 3d program.

Then use 'skin' modifier to skin the mesh to the required bone/s.

The items are 'static', no animations allowed.

Jiggle bones can do a lot, but they only work when the player is moving. And they only 'jiggle' at good framerates.

Also, they can only be controlled so much, making something face a certain direct or fly backward would be tough. It might spin around and face backwards for a second, but then spin around again.

Here's something to try when you get to work with jiggle bones. You will be using a regular "has_base_spring" type of jiggle bone. These jiggle bones don't rotate your vertices but work like a spring that can extend. You will be using this type of a jiggle block in your .qc file(Taken from the Valve Developer Community):

$jigglebone "Bouncy" {
     has_base_spring {      
     stiffness 100 
     damping 1 
     left_constraint -20 20
     up_constraint -20 20
     forward_constraint -20 20
     }
 }

The constraints are applied according to the original bone positions. So, the motion you described will probably need something like -20 and 0 as the forward constraints. Also, you'll probably need a high damping value.

If you are new to jiggle bones, I suggest you watch a video tutorial like this one:

Good luck!
