how to make separate Paper animations for falling and jumping

I’m learning Unreal, and right now I’m learning paper 2D, using a video tutorial I’ve made a falling animation but he didn’t include how to make one for jumping, in comments he said something about checking velocity but I’m still very much new to this

this is the relevant area for the jumping and animation

the comment


the Video

I’ve found this page which is unhelpfully outdated for version 5

there is a plugin PaperZD which supposedly makes this easier but I’m unsure whether or not to dedicate time to learning a 3rd Party plugin that could at any point disappear or change its TOS
