I use Memao Sprite Sheet Creator to create a lot of NPCs. It's a great tool for that.

However, adding them in Construct 3 is really tedious. That's why I created a little tool for it:

This small tool generates a folder structure containing all the animations of an exported Memao character,
as well as the Construct 3 instructions for the location of the foot polygon and the origin point.
This is a real time-saver, especially when importing many NPCs.
Simply drag the sheet.png file onto the executable. Important: a config.txt file must also be located
in the sheet's directory. This file is in the tool's main directory. The config.txt file should be self-explanatory.
Just modify it as needed. After creating the folder structure, double-click a copied dummy sprite in
Construct 3 and drag the folder onto the Animations panel (on the right) in the open Animation Editor.
That's it. Very easy. Have fun.
