getAttachmentThreshold method
When the mix percentage (getMixTime / getMixDuration) is less than the
attachmentThreshold, attachment timelines are applied while this animation is being mixed out. Defaults to
0, so attachment timelines are not applied while this animation is being mixed out.
Implementation
double getAttachmentThreshold() {
return _bindings.spine_track_entry_get_attachment_threshold(_entry);
}
