Generating Animation Keypaths when layers have "." in their name

[daniel-e-gonzalez]

Hi, I have a lottie animation that has layers that have . in their name. This is causing issues with being able to generate AnimationKeypaths from an allHierarchyKeypaths call on my LottieAnimationView since the default AnimationKeypath constructor delimits by .. The generated AnimationKeypath has an entry of "" and then another entry for "myLayerName". It really should have a single entry for ".myLayerName".

I am able to work around this by using AnimationKeypath(keys: myKeys) (where myKeys is generated using some workaround code), but I would like to instead be able to just use AnimationKeypath(keypath: keypath). Can this be fixed?

Which Version of Lottie are you using?

Lottie 4.5.0

Expected Behavior

AnimationKeypath(keypath: keypath) returns the correct keypaths when layers have . in the name.

Actual Behavior

There is a blank entry and an incorrectly named entry in the keypath.

We could make it so \. escapes the . to be a part of the layer name rather than a separator, but this risks breaking existing use cases of \ in key paths. I think using AnimationKeypath(keys:) is a pretty reasonable workaround.

Got it. I'm ok with using the workaround, but just out of curiosity, is it ever valid for there to be an entry in the AnimationKeypath that is just ""? If it isn't, it could be possible for the Lottie library to detect if this edge case has occurred and adjust it accordingly.

Thanks for the quick responses on all of this!

ah, sorry i just realized that only happens in my specific case where my layer name begins with "." so not really a great rule it can use i suppose :/
