SpriteLoop is a free 2D animation tool similar to Spine or Spriter created by Balkan Ram Games - balkanramgames.itch.io/spriteloop
My community made plugin allows you to use the exported .spla animation file format it can export and drag and drop it into Construct 3.
Features a large assortment of Actions and Expressions to control the animations
Supports SpriteLoop's keyframe event/data triggers and skin / image variants features.
As a bonus tool I also created a tool that will convert PSD files into SpriteLoop's import file format so that you can Setup your character the same way you drew it in your favorite art tool that exports PSD files. (Like Affinity or Krita)

How to Use:
After installing the plugin and restarting Construct 3, simply drag an exported .spla file from SpriteLoop into the Construct 3 layout viewport.
Control the animations etc via construct 3 actions.
