I've been making ImageDissolve transitions for Ren'py the old fashion way of writing the whole line of code and editing the variables in the editor.
after a while the whole deal got too time consuming and reloading the game for every single change didn't seem right, therefor I created this little tool to help me. the only thing you need to do is specify the folder that you're putting the images in, run the game, load the image from the list, tweak the parameters and copy the transition to your game.
This tool helps you customize and preview the transitions live without reloading. it's much faster and easier.
I will ship it with few empty directories that I'm planning to fill with new images in the future and one folder containing my older creations inside the "old" directory.
it is created on top of the 0GUI theme (as you can in the video) but it's nod dependent on it and should work with your game's theme smoothly.
the "clip.rpy" contains a small function that helps with copying the transitions into your clipboard to paste into your game. it's a part of extra functions that I'm adding to the 0GUI, if you already have that in your game you can remove this file.
