I just wanted to revisit an old topic:
Exporting sprites from Construct 3 to work with them in another editor (or whatever).
Some guy talked about making a script to loop through all the graphics and export them frame by frame.
Turns out it is a MUCH easier solution:
The .c3p project file is actually just some sort of archive (ZIP?).
Using 7-zip (Use your favorite archive software) I was able to extract the file to a folder, an in that folder you have all the assets for your game neatly sorted in sub-folders.
one of those folders is names images
, and in there you will find all the graphics for your game.
Cheers!
