Hey, guys!
I just wanted to let you know I uploaded a free Construct 3 template on Itch.io:
https://sleepingpandagames.itch.io/gameboy-like-color-transition-template-for-construct-3
This is a Construct 3 sample project with 3 native functions that can be used to mimic the GameBoy color transition animation you can see in GB games.This C3 project is very tiny so that you can easily add it to existing projects or new ones.
It uses C3 native plugins AJAX, and JSON to make things work. Color palettes and their respective RGB values are stored in a simple .json file that we can load into our C3 project using one simple AJAX call.
I hope this can be useful to you.
Let me know if you need help, or if you'd like to suggest new features.
