Timeline support has now been added for Unity 2019!
You can download the latest unitypackage from here as usual:
Spine Unity Download
Then go to Edit - Preferences - Spine
and at Timeline Package Support
hit Enable
to automatically perform all necessary steps to activate the Timeline components for Unity 2019.
The full description as in the Changelog:
Timeline Support for Unity 2019 using the existing Timeline components. By default, all Spine Timeline components are deactivated in Unity 2019 and can be activated via the Spine Preferences menu. This step became necessary because in Unity 2019, Timeline has been moved to a separate Package and is no longer included in the Unity core. Please visit Edit - Preferences - Spine
and at Timeline Package Support
hit Enable
to automatically perform all necessary steps to activate the Timeline components.
This will automatically:
- download the Unity Timeline package
- activate the Spine Timeline components by setting the compile definition
SPINE_TIMELINE_PACKAGE_DOWNLOADED
for all platforms
- modify the
spine-unity.asmdef
file by adding the reference to the Unity Timeline library.
