I've made a new pack of transitions while I was watching YouTube. My brain had no involvement in creating these, therefore they didn't came out as perfect as I prefer, but I leave it to you to decide if they're look good enough for your games.
There's no script file on the side, but you can look into the files provided in the first post to see how to define a new transition from these.
you can download these for free from both:
