change offset in different animations of a transform constraint

Pixelsmil

Hello!
I've been searching for a while but can't find if it's possible to do this. I have an IK that is affecting some bones and I need to change some values in different animations. I realized that I can make changes in the mixing and store keyframes but the changes of the offset is global even if i try to change it from the Animate mode. It's not possible to do this, right? Or I'm doing something wrong?

Thank you!

For more context, I'm trying to have a character with different ranged weapons types so for 2 handed weapons I'm using that IK but for pistols I need to tweak those offset values.

My plan B is having another IK just for pistols but it doesn't sounds as the cleanest solution.

Pixelsmil It is the correct solution to have a transform constraint for each position that you want to be matched to. If you change weapons using skins, it is possible to activate certain constraints only while a particular weapon skin is active by adding the corresponding constraints for the skin. See the "Skin sonstraints" section of the Spine User Guide for more information: https://esotericsoftware.com/spine-skins#Skin-constraints

You could have different constraints for each different kind of gesture, and if you're worried about performance, you can turn each of these gun/pistols/firearm into a separate skin and add the respective constraints to have them work to the skin

If skins are not an option, you could choose to layer animations as in the Spineboy example project:

Ok, fixed!.
I wasn't understanding correctly how to use constraints. What I did is just keeping one IK and add more transform constraints so now I can have any weapon type. I will consider using skins to manage those, thanks for the example! You helped me a lot.

Thanks for the fast reply!

Just to clarify that answer (it popped up on my search)...
Is it correct that none of the Offset values on a transform constraint are keyable, animatable? That seems to be what's indicated here, just not so explicitly.
I'd like to have a character flip an upward-pointing wand into the air, then grab it, constrained once again in her hand but now downward pointing. Changing the Offset -> Rotate 'does' that when the mix values are re-set to 100, but that Offset -> Rotate attribute is not keyed. Seems I should create a 2nd constraint for that.
Do you know if keyable offsets are on a list for later releases, in development? I'd find that very handy - fewer modules/controls = better.
Thanks!

You're correct, transform constraint offset is not keyable and using a second constraint could be a solution to have the wand pointing downward after the flip. Another option might be to check Relative, then you could key the wand to rotate +180 degrees.

It could be useful to key offset sometimes, though we don't have short term plans to do so.
